What temperature is considered a fever in children. How to accurately measure a child’s temperature. When is a fever too high for a baby or child. When should you take your child to the doctor for a fever. How to keep a child comfortable during a fever.

Understanding Fever: A Natural Defense Mechanism

Fevers, while often concerning for parents, serve an important purpose in the body’s defense against infections and inflammation. Dr. Brandon Smith, assistant professor of pediatrics at Johns Hopkins, explains:

“Fever is a well-designed, natural weapon that the body uses to fight off infections or inflammation. An infection or inflammation in the body releases signals in the blood that tells the body to raise its temperature setting. The rise in temperature helps send out cells from the immune system to fight off infection or bring down inflammation in the body.”

This understanding can provide some reassurance to parents, but it’s still crucial to know when a fever requires medical attention.

Defining Fever in Children: What Temperature is Considered Too High?

Contrary to common belief, not all elevated temperatures constitute a fever. Dr. Amna Husain, a pediatrician at Pure Direct Pediatrics, clarifies:

“A fever is any temperature above 100.4 degrees Fahrenheit (F) or 38 degrees Celsius (C). A lot of parents believe 99-100 F are fevers for kids, but these are considered normal variations of the body’s temperature — a true fever in children is 100.4 F. While the average median core temperature is 98.6 F, normal temperature fluctuates throughout the day.”

Understanding this threshold can help parents distinguish between normal temperature variations and actual fevers.

Temperature Variations Throughout the Day

It’s important to note that body temperature isn’t constant. Factors such as time of day, physical activity, and even the menstrual cycle in older girls can affect body temperature. Typically, body temperature is lowest in the early morning and highest in the late afternoon or evening.

Accurate Temperature Measurement: Best Practices for Parents

When it comes to measuring a child’s temperature, accuracy is key. Dr. Brandon Smith advises:

“Although there are a variety of methods for taking a child’s temperature, the most accurate ways are rectally in infants and young children and orally in older children. Under the arm, on the forehead and simple touching are easy, but not great ways to measure temperatures.”

Different Methods of Temperature Measurement

• Rectal temperature: Most accurate for infants and young children
• Oral temperature: Suitable for older children who can follow instructions
• Axillary (armpit) temperature: Less accurate but can be used as a quick check
• Temporal (forehead) temperature: Convenient but less reliable than rectal or oral methods
• Tympanic (ear) temperature: Quick but can be affected by ear wax or improper placement

Parents should consult with their pediatrician about the most appropriate method for their child’s age and condition.

When is a Fever Too High? Understanding the Danger Zone

While the number on the thermometer can be alarming, it’s not always the most critical factor. Dr. Nick DeBlasio, a pediatrician at Cincinnati Children’s Hospital Medical Center, explains:

“For kids older than 12 weeks, there isn’t an exact temperature that warrants a medical evaluation, as so much of it depends on how the child is acting, what other symptoms they’re having and how long the fever has lasted.”

However, there is one crucial exception: infants under 12 weeks old with a rectal temperature of 100.4 F or higher require immediate medical attention, as this could indicate a dangerous infection.

Debunking Fever Myths

It’s a common misconception that high fevers can cause brain damage. Dr. Smith clarifies:

“Sometimes parents are worried that a higher fever may cause harm to the brain or death in their child. This isn’t true. Fevers don’t harm the body. Instead they help to fight off whatever infection or inflammation is happening.”

Fevers rarely exceed 106 F, and the body has mechanisms to prevent dangerous temperature elevations.

When to Seek Medical Attention: Key Signs and Symptoms

While fevers often resolve on their own, certain situations warrant a call to the pediatrician. Dr. Smith outlines the following scenarios:

1. The child is under 3 months (12 weeks) of age and has a rectal temperature of 100.4 F or higher.
2. The child shows very low energy, extreme tiredness and is not acting themselves.
3. Fever has been going on for more than three days.
4. Other symptoms are present, such as sore throat, vomiting, ear pain, belly pain or pain when urinating.
5. The child is drinking less than usual and has had fewer than four wet diapers in a span of 24 hours or two urinations while they’re awake for the day.
6. The child is having trouble breathing (this should warrant a call to the doctor whether or not a fever is present).

These guidelines can help parents determine when professional medical evaluation is necessary.

Managing Fever at Home: Comfort Measures and Treatment Options

While waiting for a fever to resolve or before seeking medical attention, there are several ways to keep a child comfortable:

Hydration

Ensuring adequate fluid intake is crucial during a fever. Offer water, clear broths, or electrolyte solutions designed for children. For infants, continue breastfeeding or formula feeding as usual.

Rest

Encourage the child to rest and sleep as much as possible. The body needs extra energy to fight off infection.

Clothing and Environment

Dress the child in lightweight, breathable clothing. Keep the room temperature comfortable, but avoid making it too cold.

Fever-Reducing Medications

Over-the-counter medications like acetaminophen or ibuprofen can help reduce fever and alleviate discomfort. Always follow dosage instructions based on the child’s weight and age, and consult with a healthcare provider before administering any medication.

Cool Compresses

Applying a cool, damp cloth to the forehead, wrists, or back of the neck can provide comfort. Avoid cold baths or alcohol rubs, as these can be counterproductive and potentially dangerous.

Fever in Special Populations: Considerations for Infants and Immunocompromised Children

Certain groups of children require special attention when it comes to fevers:

Infants Under 3 Months

As mentioned earlier, any fever in infants under 12 weeks of age requires immediate medical attention. Their immune systems are still developing, making them more susceptible to serious infections.

Immunocompromised Children

Children with weakened immune systems due to chronic conditions, cancer treatments, or other factors may be at higher risk for complications from infections. These children often require more aggressive evaluation and treatment of fevers.

Children with Chronic Medical Conditions

Children with conditions such as heart disease, lung disease, or sickle cell anemia may have different thresholds for when a fever becomes concerning. Parents of these children should have a clear plan from their healthcare provider about when to seek medical attention for fever.

Understanding Fever Patterns: What They Can Tell Us

The pattern of a fever can sometimes provide clues about its cause:

Continuous Fever

A fever that remains steady and elevated may indicate a bacterial infection.

Intermittent Fever

Fevers that come and go might suggest a viral infection or certain inflammatory conditions.

Remittent Fever

A fever that fluctuates but never returns to normal may be seen in some serious bacterial infections.

Periodic Fever

Fevers that occur in regular patterns over weeks or months might indicate rare conditions like periodic fever syndromes.

While these patterns can be informative, they should always be interpreted by a healthcare professional in the context of the child’s overall clinical picture.

The Role of Fever in Different Illnesses: Viral vs. Bacterial Infections

Fevers can be caused by various factors, but infections are the most common culprits in children. Understanding the differences between viral and bacterial infections can help parents know what to expect:

Viral Infections

• Often cause fevers that last 3-5 days
• Typically resolve on their own without antibiotics
• Common examples include colds, flu, and many stomach bugs
• May be accompanied by symptoms like runny nose, cough, or diarrhea

Bacterial Infections

• Can cause higher fevers that persist longer
• Often require antibiotic treatment
• Examples include strep throat, pneumonia, and urinary tract infections
• May be associated with more severe symptoms or localized pain

It’s important to note that distinguishing between viral and bacterial infections often requires medical evaluation and sometimes laboratory tests.

Fever Prevention: Strategies for Keeping Children Healthy

While not all fevers can be prevented, there are steps parents can take to reduce the risk of infections:

Hygiene Practices

• Encourage regular handwashing, especially before eating and after using the bathroom
• Teach children to cover their mouths and noses when coughing or sneezing
• Avoid sharing utensils, cups, or personal items

Vaccination

Keeping children up-to-date on recommended vaccinations can prevent many serious infections that cause fever.

Healthy Lifestyle

• Ensure children get adequate sleep
• Encourage a balanced diet rich in fruits and vegetables
• Promote regular physical activity to boost the immune system

Avoiding Exposure

When possible, limit contact with individuals who are sick, especially during cold and flu season.

The Psychological Impact of Fever on Children and Families

While the physical aspects of fever are well understood, the psychological impact on both children and their families is often overlooked:

Children’s Perspective

For children, fever can be a confusing and sometimes frightening experience. They may feel uncomfortable, irritable, and unsure of what’s happening to their bodies. It’s important for parents to provide reassurance and explain the situation in age-appropriate terms.

Parental Anxiety

Parents often experience significant anxiety when their child has a fever. This “fever phobia” can lead to overuse of fever-reducing medications or unnecessary medical visits. Education about the purpose and management of fever can help alleviate this anxiety.

Family Dynamics

A child’s illness can disrupt family routines and cause stress for siblings and other family members. Open communication and involving other family members in care (when appropriate) can help maintain a sense of normalcy.

Long-Term Effects

Repeated experiences with fever and illness during childhood can shape a person’s approach to health and medical care in adulthood. Positive, supportive experiences during childhood illnesses can foster resilience and a balanced approach to health management later in life.

Fever and Child Development: Understanding the Broader Context

While fevers are often seen as purely negative events, they can play a role in a child’s overall development:

Immune System Maturation

Exposure to various pathogens and the body’s subsequent immune response (including fever) helps strengthen and mature the immune system over time.

Cognitive Development

Experiences with illness can contribute to a child’s understanding of their body and health concepts. These experiences provide opportunities for learning about self-care and the importance of health.

Emotional Development

Navigating the challenges of illness can foster resilience and coping skills in children. The care and attention received during illness can also reinforce attachment bonds with caregivers.

Social Understanding

Illness experiences can help children develop empathy and understanding for others who are sick or facing health challenges.

While fevers and illnesses should never be sought out, understanding their potential developmental impacts can help parents frame these experiences more positively for their children.

The Future of Fever Management: Emerging Technologies and Approaches

As medical science advances, new technologies and approaches are emerging that may change how we monitor and manage fevers in children:

Continuous Temperature Monitoring

Wearable devices that continuously monitor body temperature are being developed. These could provide more accurate fever tracking and early warning of temperature spikes.

Smart Thermometers

Some new thermometers can connect to smartphone apps, allowing for easy tracking of temperature trends and symptoms over time. This data can be shared with healthcare providers for more informed decision-making.

Telemedicine

The growth of telemedicine services allows parents to consult with healthcare providers remotely, potentially reducing unnecessary emergency room visits for fever.

Improved Diagnostics

Rapid diagnostic tests that can quickly distinguish between viral and bacterial infections are becoming more widely available. These could lead to more targeted treatment approaches.

Personalized Medicine

As our understanding of individual genetic and immune system variations grows, more personalized approaches to fever management may emerge, tailored to each child’s unique physiology.

While these advancements hold promise, it’s important to remember that they should complement, not replace, the fundamental principles of fever management and the invaluable role of attentive caregiving.

What is considered a fever in children? When to worry and when you can chill

They may be a common symptom of cold and flu viruses, but fevers in children have the ability to unnerve even the most experienced of parents and caretakers. But here’s some (emotional) comfort: A higher-than-normal temperature isn’t all bad. 

“Fever is a well-designed, natural weapon that the body uses to fight off infections or inflammation,” says Dr. Brandon Smith, assistant professor of pediatrics at Johns Hopkins in Baltimore. “An infection or inflammation in the body releases signals in the blood that tells the body to raise its temperature setting. The rise in temperature helps send out cells from the immune system to fight off infection or bring down inflammation in the body.”

“Fever is a well-designed, natural weapon that the body uses to fight off infections or inflammation.”

All of that said, when the number on the thermometer continues to rise, it isn’t exactly easy to relax. Here, experts and parents weigh in on what to look for and what to do when a child comes down with a fever, along with tips on how to keep them comfortable — because you want to keep your cool when they’re hot.

What temperature is considered a fever for a child?

According to Dr. Amna Husain, a pediatrician at Pure Direct Pediatrics in Marlboro Township, New Jersey, a fever is any temperature above 100.4 degrees Fahrenheit (F) or 38 degrees Celsius (C). “A lot of parents believe 99-100 F are fevers for kids, but these are considered normal variations of the body’s temperature — a true fever in children is 100.4 F,” Husain explains. “While the average median core temperature is 98.6 F, normal temperature fluctuates throughout the day.”

What is the most accurate way to take a child’s temperature?

Something to keep in mind: When it comes to taking a child’s temperature, assessing their core (internal) temperature will yield more reliable results than outward skin temperature.  

“Although there are a variety of methods for taking a child’s temperature, the most accurate ways are rectally in infants and young children and orally in older children,” says Smith. “Under the arm, on the forehead and simple touching are easy, but not great ways to measure temperatures.”

When is a fever too high for a baby or child?

While it may be tempting to compulsively check a child’s temperature when they’re not feeling well, how they’re acting and feeling, as well as the duration of the fever, is more important than the number on the thermometer. 

The only absolute that a fever is too high in a child and the doctor should be called immediately is when there’s a rectal temperature of 100.4 F or higher in infants 12 weeks of age or younger, as this may be a sign of a dangerous infection. “This is considered a medical emergency,” says Dr. Nick DeBlasio, a pediatrician at the Pediatric Primary Care Center at Cincinnati Children’s Hospital Medical Center in Cincinnati. 

“For kids older than 12 weeks, there isn’t an exact temperature that warrants a medical evaluation, as so much of it depends on how the child is acting, what other symptoms they’re having and how long the fever has lasted.” If a child is generally feeling and acting OK, and no symptoms are present other than fever, DeBlasio likes to evaluate them within three days. “If they are acting sick or complain of other things, such as a sore throat, ear pain, poor urine output or breathing problems, I like to see them sooner,” he says.

It’s also worth noting that high fevers don’t cause brain damage. “Sometimes parents are worried that a higher fever may cause harm to the brain or death in their child. This isn’t true,” says Smith, who notes that a fever rarely — if ever — will go above 106 F. “Fevers don’t harm the body. Instead they help to fight off whatever infection or inflammation is happening.”

When should I take my child to the doctor for a fever?

Here’s when parents and caregivers should call the pediatrician for a fever, according to Smith:

• The child is under 3 months (12 weeks) of age and has a rectal temperature of 100.4 F or higher.
• The child shows very low energy, extreme tiredness and is not acting themselves.
• Fever has been going on for more than three days.
• Other symptoms are present, such as sore throat, vomiting, ear pain, belly pain or pain when urinating.
• The child is drinking less than usual and has had fewer than four wet diapers in a span of 24 hours or two urinations while they’re awake for the day.
• The child is having trouble breathing (this should warrant a call to the doctor whether or not a fever is present).

Other signs a child should be evaluated by their doctor, according to the American Academy of Pediatrics (AAP):

• The child has been in a very hot place, such as a car.
• A stiff neck, severe headache or unexplained rash are present.
• The child has immune system problems, such as cancer, or is taking steroids.
• A seizure has occurred.
• The child seems to be getting worse.

Child fever temperature chart

Child’s age	When to see a doctor
Infants and babies (newborn – 3 mos.)	100.4 degrees or higher
Babies (3 mos. +), as well as toddlers, big kids and teens	100.4 degrees or higher AND any of the following: • Very low energy, extreme tiredness, not acting themselves. Fever for 3+ days. Other symptoms, such as sore throat, vomiting, ear pain, belly pain, or pain when urinating. • Child is drinking less than usual and has fewer than four wet diapers in a span of 24 hours or two urinations while awake for the day. • The child is having trouble breathing.

What causes fever?

Fevers are typically caused by infections from viruses (think cold and flu) or bacteria (think strep), according to the AAP. And the fever itself isn’t the illness, but instead a byproduct of the infection — and a good one at that.  

“Fever is a protective mechanism from the immune system,” says Husain. “It’s a sign that the immune system is on to whatever pathogen the body is fighting.”

Other, less common, causes of fever in children, are:

• Immunizations. Some kids get a low-grade fever after getting a vaccination, according to the AAP.
• Overdressing. Infants, who don’t regulate body temperature as well as older kids, may get a fever if they’re dressed too warmly or are in a hot environment. (Even if you suspect this is the cause of fever, though, it’s imperative you call their doctor if they’re 12 weeks or younger. )
• Teething. Sometimes teething can result in a slight rise in body temperature, but typically it won’t cause a temperature over 100 F. “When any of my kids were teething, they always felt a little warmer than usual and had a faint rise in temperature,” says mom of two Alissa Davenport of Rochester, New York. “If they were running a little hot and drooling a ton, I usually knew it was teething.”

How to bring down a fever in a child

If a child has a fever but generally seems OK — they’re playing, eating and drinking and have their usual energy — the fever may not need to be treated. “As a pediatrician and a mother, I advocate treating a fever if the child is uncomfortable,” says Husain. “If they’re running around and playing as normal, why treat? On the other side of the spectrum, I’ve treated my daughter with Tylenol when she is ill with a viral process but fever-free to provide comfort and pain relief.”

“As a pediatrician and a mother, I advocate treating a fever if the child is uncomfortable. ”

DR. AMNA HUSAIN, PEDIATRICIAN

If a child is generally feeling crummy when they have a fever, either ibuprofen (only after 6 months of age) or acetaminophen can be used in appropriate doses. “Many pediatricians advise sticking to just one of these medications to make sure there’s no confusion and extra doses aren’t given,” says Smith.  

Some parents and caregivers also like to use baths to help bring down a fever — which is OK, so long as the temperature is appropriate. “Sponging or using a washcloth can help a child feel better and bring down their temperature, but it’s important that the water is lukewarm and not cold,” notes Smith. “Cold baths or sponging with cold water will just cause your child to shiver and won’t help to make them feel better.” 

What to know about fever, kids and COVID-19 

These days, isn’t uncommon for parents and caregivers to wonder about COVID-19 when a child comes down with a fever. However, it’s important to know that, while fever is a sign of COVID-19, it doesn’t necessarily mean a child has COVID-19. That said, it’s still important to stay vigilant.

“Fever is one of the most common symptoms that people with COVID-19 have, but it can also be a sign of another infection,” says Smith, who adds that it’s also important to think about the child’s risk of getting COVID. In other words: Were the in close contact with someone who had or has COVID?

When in doubt, Smith says, always call your child’s pediatrician, who will either have them come in for an exam, or, at the very least, offer some peace of mind.

How to Effectively Treat Your Baby’s High-Temperature Fever

As a parent, nothing is more precious than your child. If your little one is exhibiting signs and symptoms of a high temperature,  your natural reaction might be to panic. Not to worry — you can easily assess the severity of their fever at home by using a baby fever chart. 

It’s normal for your baby’s temperature to fluctuate for various reasons, and it’s not always necessarily a bad thing. But you may be wondering what is a fever for a baby.

Below, we’ll explain the baby fever chart to help decide whether you should treat your little one’s fever at home and when you should call the pediatrician or local urgent care center.  

Infant, Toddler, and Baby Fever Chart

It’s normal for your baby’s temperature to fluctuate for various reasons: from physical exertion, taking a warm bath, fighting allergies, or even digestion and heightened metabolism. Even the time of day can have an impact since body temperatures tend to rise in the afternoon and early evening.

Use the baby fever chart below to help assess your child’s situation to know how to effectively treat the fever.

What Temperature is Considered a Fever for a Baby?

Many people do not know what temperature is a fever for a baby, and therefore do not always properly manage the specific situation.

Your child is considered to have a fever if he or she:

• Has a rectal, ear or temporal artery temperature of 100. 4 F (38 C) or higher
• Has an oral temperature of 100 F (37.8 C) or higher
• Has an armpit temperature of 99 F (37.2 C) or higher

If you’re in doubt about a temperature reading, use another method to confirm the results.

Use the Right Thermometer to Determine Fever in Babies

To determine whether your child does indeed have a fever, it’s necessary to obtain the right temperature measurement. This starts with having the right instrument. Regardless of your baby’s age, a digital multiuse thermometer is recommended.

Not only is a digital thermometer inexpensive and easy to use, it’s also the most reliable temperature-taking instrument. There are several ways to take your child’s temperature with a digital thermometer. 

• Rectal thermometers – These are recommended whenever possible as they give the most accurate readings, especially for babies and toddlers under 2 years old. However, they typically aren’t fun for you or your baby.
• Armpit thermometers – This method may be easier to obtain a temperature in your little one, but they aren’t as accurate.
• Tympanic (ear) or temporal (forehead) thermometers – These methods aren’t as precise because they can be skewed by external temperatures. Mercury thermometers should be avoided at all times because if they were to break, they would expose your child to their toxic effects.

Since a rectal temperature is considered the most accurate method to assess temperature in babies, this is recommended whenever possible.

How to Reduce Baby Fever at Home

Should your child seem uncomfortable or in pain, there are several options for baby fever treatment at home to help him or her feel better. 

Baby Fever Treatment Methods

Fever-reducing medicines such as ibuprofen (for babies over 6 months) and acetaminophen can provide some relief, but there are other baby fever treatment methods that can lower a temperature:

• Cold compress – Placing a cool, wet washcloth on your child’s head can draw the fever out and help your baby rest.
• Fluids – To prevent dehydration and aid the body in cooling itself, give your child plenty of fluids, including water, clear soups, popsicles, or yogurt. If your baby is younger than 6 months, breast milk will hydrate and strengthen your little one’s immune system while fighting illness.
• Keep baby’s room cool – Use air conditioning or a fan on its low setting to keep your baby’s room at a comfortable temperature (70-74ºF). Also, try to avoid taking your child outside in the sun. Should you venture out, remain in the shade.
• Lightweight clothing – Remove extra layers of clothing so your child can lose heat more easily through the skin. Since infants can’t regulate their temperature well, it’s harder to cool them down once overheated with multiple layers.
• Lukewarm sponge bath – Help your child feel more at ease with a relaxing sponge bath using lukewarm water. As water evaporates from his or her skin, it can bring the fever down temporarily. But avoid using cold water as this can cause your baby to shiver, raising his or her temperature.

Whatever you choose to do to alleviate discomfort, do not use aspirin as this can cause a potentially fatal illness called Reye’s syndrome.

How to Dress Baby with Fever at Night

If your baby has a fever or chills, it may be tempting to dress them in extra clothes and blankets. However doing this may actually prevent the fever from coming down or make it go higher, adding to your child’s discomfort. 

Instead, dress your baby in a single layer of light, comfortable clothes and one lightweight blanket to sleep with. Keep their room temperature comfortable – not too hot or too cold.

What Causes Fever in Babies and Toddlers

It’s important to remember a fever is not itself an illness. Instead, it’s a symptom of another underlying issue. In most cases, the issue is probably an infection; however, depending on what type of infection it is or whether it’s another problem will determine the course of treatment. 

Some of the most common causes are:

• Viral infection – Viruses like an intestinal infection, the cold or flu, croup, or chickenpox can cause your baby to develop a fever as a natural response to fighting off infection. Since viruses are not bacterial in nature, antibiotics will, unfortunately, have no effect.
• Bacterial infection – While less typical than viral fevers, bacterial fevers can be a much more serious infection. Ear and throat infections, urinary tract infections, bacterial pneumonia, or bacterial meningitis require antibiotics to prevent additional health complications.
• Over bundling – Because they can’t regulate their bodies as well as older kids, infants – particularly newborns – can get fevers if they’re overdressed or in a warm environment. Make sure your baby is not over-bundled with extra blankets or clothes, causing a rise in body temperature. Also, check to see that his or her room is comfortable – not too hot or cold.
• Immunization – If your child received a vaccination in the past 24 hours, he or she might experience a low-grade fever. This should be nothing to worry about, and appropriate dosages of infants’ or children’s acetaminophen or ibuprofen can be used to alleviate pain. But, if the fever persists past 48 hours, it’s advisable to call your doctor or visit an urgent care center.
• Teething – It’s possible for your infant to develop a slight rise in temperature because of new teeth coming in. Rubbing your child’s teeth or using a teething ring can help. If your baby’s teething fever lasts longer than 2 days, seek medical advice.

It can be difficult to determine what is causing the fever, which is why many doctors will order a blood, urine test, or X-ray to pinpoint the root cause.

When to Seek Medical Treatment

Let’s say your little one is showing signs of a fever and you take his or her temperature. Just because your thermometer reads 102ºF, it shouldn’t be cause for alarm. What some parents don’t know is that a higher temperature reading doesn’t necessarily correlate to a sicker child.

However, you should call your doctor or urgent care center if your baby:

• Has a rash
• Is not eating
• Is not sleeping well
• Is very cranky, irritable, or difficult to calm down

If you’re ever in doubt, it’s always best to play it safe and call your pediatrician or local urgent care for advice.

When to go to the Emergency Room 

Take your child to the emergency room right away or call 911 if they have any of the following symptoms:

• Has a seizure
• HAS purple or blood-colored spots on their skin
• Is having trouble breathing
• Is lethargic or not responsive
• Shows signs of dehydration, such as fewer wet diapers, crying without tears or having a sunken soft spot on their head

These symptoms indicate your baby’s fever is serious and should therefore be treated urgently.

When to Take a Baby to GoHealth Urgent Care

If your child has a fever, they are not alone – infants and toddlers get fevers. While at the onset you might be worried, just know that your baby should be back to its normal, rambunctious self within a few days.

Rather than basing the severity of your child’s fever on just a thermometer reading, be aware of how your little one’s actions, as this can be a more telling sign of what is going on.

Plus, make sure not to mistake a fever for heatstroke, which is caused by external heat rather than an infection or internal condition. When a baby is left in a very hot place, like a closed car or warm beach in the summer, it can cause body temperature to rise to fatal levels.

You know your baby better than anyone. Whether you’re a new mom or a dad of four, if you’re concerned, don’t hesitate to contact your family doctor for an appointment or advice. Your local GoHealth Urgent Care Center has visit times available when you cannot wait for your primary care provider, for what could be days.

Because when your baby’s back to smiling and playing, as usual, you’ll be able to relax once again – at least about their high-temperature fever!

Bringing down a high temperature is dangerous for others: this leads to additional cases of infection

A decrease in elevated temperature annually leads to 700 additional deaths in the United States, scientists have shown on a mathematical model.

Many people during illness, feeling unwell, reduce fever by taking antipyretics – aspirin, paracetamol, and so on. Indeed, the body does not tolerate an increase in temperature, and, having knocked it down, a person subjectively begins to feel better. But the disease does not go away. Doctors warn that a temperature that is not too high (as a rule, they call a figure below 38.5 degrees) should not be brought down, as it helps the body fight infection. Now scientists have summed up the evidence base for this statement:

they used a mathematical model to prove that at least 700 people die of the flu every year in the United States because it is common practice in society to use antipyretics.

These results were published by specialists in infectious diseases, as well as mathematics and statistics from McMaster University in Hamilton (Ontario, Canada) in Proceedings of the Royal Society B .

Influenza pandemic with a trail

Influenza pandemics can be predicted using the results of the work of Moscow State University scientists, who were the first in the world to study. ..

The tradition of lowering body temperature when sick has been around for thousands of years. Hippocrates recommended taking an infusion of willow bark, which was later shown to contain acetylsalicylic acid, or aspirin. The ancient Romans, Chinese and Indians used other plants with similar properties to lower the temperature.

Fever (fever) is an initially protective and adaptive reaction, in which high temperature creates unfavorable conditions for the reproduction of pathogens and, on the contrary, enhances the action of the immune system.

Body temperature rises under the influence of pyrogens. External pyrogens are lipopolysaccharides of the shell of bacteria, internal pyrogens are produced by cells of the immune system. As a result, the thermoregulation of the body is rebuilt in such a way that heat production begins to increase heat transfer. But there is a threshold for a safe rise in temperature, because too high becomes dangerous for the body itself.

It was only in the 1970s that some doctors began to suggest that there was a benefit to raising the temperature during an infection: bacteria and viruses multiply more poorly. So, its decrease allows them to multiply, and the disease continues. Article 19For 75 years, in the Journal of the American Medical Association , researchers have proven that

in people infected with rhinovirus, if they take aspirin to reduce fever, the virus multiplies faster in the body.

Another work showed that the influenza virus in ferrets was more rapidly transmitted from one animal to another if their body temperature was lowered.

In a new study, mathematician David Earn and his colleagues at McMaster University applied a mathematical model to the American population and estimated how quickly the virus spreads if infected people lower their temperature, and how many additional infections occur. They concluded that the use of antipyretic drugs in the US results in at least 1% of additional influenza cases and 700 excess influenza deaths per year. However, it all depends on how easily the virus is transmitted from person to person.

If the virus is transmitted worse, helping it in the form of lowering the temperature will add 5% extra flu cases and 2,000 extra deaths.

The influenza virus is predictable

However, some experts are critical of the data obtained. “The conclusion is not without merit,” said Philip McWick of the University of Maryland. “Although some of the data embedded in the model are derived from animals and may be very different from what happens in the human population.” He is referring to data on the best transmission of the influenza virus when the temperature drops in ferrets. Epidemiologist Gerard Krause of the Helmholtz Infection Research Center adds that better transmission of the virus does not always result in more people being infected.

But David Earn claims that he and his colleagues were as correct as possible in their conclusions. They also considered such a scenario that

people who lowered the temperature, for example, with the help of aspirin, feel better and go to work, thereby transmitting the virus to colleagues.

And he adds that the behavior of the virus in the body with a decrease in temperature remains to be carefully studied. Scientists admit that we still know unforgivably little about the benefits or harms that an increase in temperature in the human body brings.

In general, if you are ill, whether or not to lower your temperature is a personal matter for everyone. But we must understand that taking antipyretics is not a treatment, but only a temporary relief.

What does a fever mean? ✅ Information for patients from experts Sanmedekspert

Since childhood, we know that there is a normal temperature, and sometimes it is “bad”. The norm is a temperature of 36. 6 degrees. Everything above and below indicates that something is wrong in the body.

The reasons for the rise in temperature can be quite innocent: for example, in women around the middle of the cycle, when ovulation occurs. The thermometer readings may increase after intense physical exertion – this is normal. But sometimes the reasons are much more serious.

The first thing to do is to listen carefully to yourself and try to understand what else is bothering you besides the fever. The effectiveness of the treatment that the doctor prescribes will depend on how correctly you determine this. At very high temperatures (above 39degrees) the condition can be very serious, and the best thing to do is to immediately call an ambulance. A strong fever can be accompanied by convulsions, a short-term loss of consciousness, even delirium – in a word, this is not a state when it is enough just to lie down at home.

What is fever and what does it mean?

Specialists distinguish elevated (febrile) temperature (above 38 degrees) and subfebrile (37 – 38 degrees). They are tolerated in different ways, and, as a rule, testify to different diseases.

In addition to these two species, pyretic temperature is also distinguished – above 39 degrees. This is the most dangerous case when you should not figure out the reasons on your own – you need emergency help.

Febrile temperature

Temperature above 38 degrees, as a rule, occurs in acute situations – when an infectious or viral disease begins to develop in the body, since it is at this temperature that the causative agents of such diseases – bacteria and viruses – die.

The body can also react to poisoning by a sharp rise in temperature.

If you have wounds and unhealed injuries, a rise in temperature is a very dangerous signal that may mean that an infection has attacked the injured area.

Among the diseases that are accompanied by fever, the most common are:

• Influenza . It differs from ARVI, first of all, in heat. As a rule, it is accompanied by pain in the muscles and joints, but catarrhal phenomena (cough, runny nose) join later. With SARS, on the contrary, sneezing and coughing come first, and then the temperature gradually rises.
• Angina . This disease is also familiar to everyone since childhood, and it is difficult to confuse it with something else – a sharp rise in temperature, soreness, swelling and sore throat: the picture is usually quite unambiguous. If a sore throat is not treated on time, it is fraught with complications, and very serious ones.
• Chicken pox and measles . These childhood diseases may well attack an adult. In the event that he did not get sick with them in childhood. Adults endure these diseases more severely than children, and are sometimes treated longer. The insidiousness is that other symptoms – except for fever – are not observed for the first two days. Characteristic vesicles on the skin appear on the third day. Therefore, if the temperature has risen, you feel unwell, but nothing hurts – it is best to immediately call a doctor at home.
• Pneumonia . In this case, in addition to fever, the patient will be disturbed by severe pain in the chest, shortness of breath, dry cough (sometimes, however, there is no cough). If the temperature is high and you find it difficult to breathe, a doctor’s call should be immediate – pneumonia can only be cured qualitatively in a hospital.
• Pyelonephritis . The inflammatory process in the kidneys also has characteristic manifestations, except for fever. There may be discomfort or pain in the lower ribs, in the side. Blood pressure rises, edema appears – because the kidneys cannot cope with the usual load. It is not worth treating yourself: the disease is serious, tends to take a chronic form and is fraught with complications.
• Hemorrhagic fever . A very dangerous infectious disease carried by rodents. A critically high temperature is accompanied by an almost complete lack of urination, muscle pain, the skin acquires a reddish tint. What to do: call an ambulance immediately.
• Gastroenterocolitis – a group of diseases that include cholera, typhoid fever, dysentery and some others. Alas, they still exist today. As a rule, in addition to fever, there are characteristic symptoms – uncontrollable vomiting or incessant diarrhea. What to do: call an ambulance, which is very likely to take you to the infectious diseases department, where they will take all the tests from you, determine the problem and prescribe treatment.
• Appendicitis . High temperature is accompanied by pain in the umbilical region, nausea, vomiting. If the stomach hurts, and these pains intensify when moving, changing the position of the body, immediately call an ambulance. An inflamed appendix in itself is not so terrible – the operation to remove it is not particularly difficult and you will recover quickly after it, but possible complications (for example, peritonitis) are extremely dangerous.
• Meningitis and encephalitis . Infectious inflammation of the meninges. The condition is severe, intense fever is accompanied by headache, visual disturbances, nausea, often spasm of the neck muscles. A hemorrhagic rash may appear on the abdomen and legs. The best thing to do is to call an ambulance and immediately begin treatment in a hospital setting.
• Hepatitis A . Of all types of hepatitis, the most harmless, but still a serious disease. It is difficult to determine in the first days – the skin and whites of the eyes acquire a characteristic yellowish tint on days 4-5, and the intense heat stops by this time.

What should I do before the doctor or ambulance arrives?

Antipyretics – paracetamol, ibuprofen, nimesil – help bring down the high temperature. And it is best to use rectal suppositories – they act faster than powders and tablets. Even if you are shivering, you can’t wrap yourself up, on the contrary, it is recommended to open as much of the body area as possible, you can do cool compresses.

Subfebrile temperature

Subfebrile temperature – between 37 and 38 degrees – would seem to be a less dangerous thing. However, it is often very hard to bear, a person feels overwhelmed, exhausted. And the worst thing is that all this can go on for weeks.

Without a strong fever, in a “sluggish” mode, people with impaired immune status, weakened ones get sick – in this case, the body simply cannot adequately respond to the disease. Most often, a small temperature accompanies SARS – after a cough and a runny nose have appeared, the thermometer begins to show ever higher numbers, and the symptoms, of course, do not disappear anywhere.

Other diseases that may be accompanied by subfebrile temperature and their symptoms:

• Exacerbations of chronic bronchitis (in this case, you will cough more than usual)
• Chronic sinusitis and sinusitis (headache, difficulty in nasal breathing)
• Asthma (cough, shortness of breath, shortness of breath)
• Pulmonary tuberculosis (unstoppable cough, possibly with blood in sputum)
• Myocarditis (pain in the region of the heart)
• Chronic pyelonephritis (pain in the side, slight swelling)
• Inflammatory diseases of the urogenital area – for example, cystitis (frequent and painful urination)
• Gastric and duodenal ulcer (abdominal pain after eating, blood in feces)
