A fever is a body temperature that’s higher than is considered normal. It’s also called a high temperature, hyperthermia, or pyrexia, and it’s usually a sign that your body is working to keep you healthy from an infection. Normal body temperatures are different for everyone, but they lie within the range of 97 to 99. A temperature of 100.4 or higher is considered a fever.

A part of your brain called the hypothalamus controls your body temperature. In response to an infection, illness, or some other cause, the hypothalamus may reset the body to a higher temperature. So when a fever comes on, it’s a sign that something is going on in your body.

Fevers themselves generally aren’t dangerous, but you should check in with your doctor if:

• An adult’s temperature is 103 or higher
• A very young infant (under 3 months) has a rectal temperature 100. 4 or higher (call your doctor or go to an emergency room immediately)
• A 3-6-month-old has a higher than normal rectal temperature and is also irritable or sleepy (call your doctor right away)
• A 3-6-month-old has a 102 or higher rectal temperature
• A 6-24-month-old has a fever higher than 102 for more than a day or with other symptoms such as a cough or diarrhea
• A child older than 2 has a fever that comes with rash, real discomfort, irritability, listlessness, headache, stiff neck, or repeated diarrhea or vomiting
• An infant or child has a seizure
• Any temperature over 104 in a child, which could cause a seizure
• Any fever that starts after someone has been in hot temperatures, which could be a sign of heat stroke
• The fever doesn’t go down after taking over-the-counter medications such as ibuprofen in the appropriate doses
• You’ve been in contact with someone who has COVID-19

Fevers are signs of some sort of illness or infection. When you have, you may also notice these symptoms:

• Chills or shivering
• Sweating
• Headache
• Feeling weak
• Being irritable
• Losing your appetite
• Being dehydrated

A fever can be a sign of several health conditions, which may or may not need medical treatment.

The most common causes of fever are infections such as colds and stomach bugs (gastroenteritis). Other causes include:

• Infections of the ear, lung, skin, throat, bladder, or kidney
• Heat exhaustion
• COVID-19
• Sunburn
• Conditions that cause inflammation, such as rheumatoid arthritis
• Side effects of medications
• Vaccines and immunizations
• Blood clots
• Autoimmune conditions such as lupus and inflammatory bowel disease (IBS)
• Cancer
• Hormone disorders such as hyperthyroidism
• Illegal drugs such as amphetamines and cocaine
• Teething in babies can cause a mild, low-grade fever (not over 101 degrees)

Although a fever is easy to measure with a thermometer, finding its cause can be hard. Besides a physical exam, your doctor will ask about symptoms and conditions, medications, and if you’ve recently traveled to areas with infections or have other infection risks. A malaria infection, for example, may cause a fever that typically comes back. Some areas of the U.S. are hot spots for infections such as Lyme disease and Rocky Mountain spotted fever.

Your doctor may ask if you have been around someone with COVID-19 or have any other symptoms of COVID-19.

Sometimes, you may have a “fever of unknown origin.” In such cases, the cause could be an unusual or not obvious condition such as a chronic infection, a connective tissue disorder, cancer, or another problem.

Fever is usually associated with physical discomfort, and most people feel better when a fever is treated. But depending on your age, physical condition, and the underlying cause of your fever, you may or may not require medical treatment for the fever alone. Many experts believe that fever is a natural bodily defense against infection. There are also many non-infectious causes of fever.

Treatments vary depending on the cause of the fever. For example, antibiotics would be used for a bacterial infection such as strep throat.

The most common treatments for fever include over-the-counter drugs such as acetaminophen and nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen. Children and teens should not take aspirin because it’s linked to a condition called Reye’s syndrome.

Stay comfortable by: 

• Drinking a lot of clear liquids such as water, broth, and juices or a rehydration drink.
• Taking a lukewarm bath.
• Resting.
• Keeping yourself cool with lightweight clothing and bed coverings.

  Countries affected by fever of unknown origin

  China

  The first cases of the unknown fever were reported in Wuhan, China in December 2019. The disease soon spread throughout the country and was also a source of concern for international health organizations.

  Italy

  At the beginning of 2020, Italy was one of the countries that faced the emergence of an unknown fever. The disease, known as COVID-19, became widespread and led to the closure of borders and the introduction of quarantine.

  Iran

  Iran has also become one of the countries where many cases of unknown fever have been reported. Soon the disease became a pandemic and caused a worldwide crisis.

  • China, Italy and Iran are the top countries affected by the unknown fever in early 2020.

  How is fever of unknown origin transmitted?

  Fever of unknown origin is spread from person to person through droplets of air, close contact with an infected person, or contact with their blood, urine, or other bodily fluids.

  It is also possible to transmit infection through the bites of infected insects, such as mosquitoes, which may carry the virus.

  It is important to note that transmission of fever of unknown origin can occur not only from sick people, but also from animals that carry this infection.

  To prevent transmission, hygiene measures such as regular handwashing, wearing masks in public places and avoiding contact with people who are sick should be followed.

  If you suspect you have a fever of unknown origin, it is important to seek medical attention and follow all your doctor’s recommendations to avoid infecting others.

  Consequences of a fever of unknown origin

  Unfortunately, a fever of unknown origin can leave serious consequences even after it has been treated.

  • Weakening of the immune system. During the fight against the disease, the body spends a lot of energy, and after it ends, the immune system may remain weakened for a while, which can lead to secondary infections.
  • Violation of the functioning of organs. In some cases, a fever of unknown origin can cause malfunction of organs such as the kidneys, liver, heart, which will require long-term treatment and rehabilitation.
  • Post-traumatic stress syndrome. People who have had a severe form of fever may develop post-traumatic stress syndrome, which manifests itself in the form of increased anxiety, nervousness, insomnia and other psychological problems.

  It is important to note that the consequences of a fever of unknown origin can be very diverse and individual in each case. Therefore, if you suspect this disease, you should immediately consult a doctor and follow his recommendations in order to minimize potential health consequences.

  How to minimize the risk of contracting a fever of unknown origin?

  1. Practice good personal hygiene. Wash your hands regularly with soap and water or use an alcohol-based hand rub. Do not touch your face with your hands unnecessarily. Cover your mouth and nose with your elbow or use disposable tissues when coughing or sneezing.

  2. Avoid contact with other people. Avoid crowded places, close contact with people who are sick or who may be infected without symptoms. If communication is necessary, wear a mask.

  3. Watch your health. Monitor temperature regularly and pay attention to symptoms. If signs of illness appear, consult a doctor immediately.

  4. Eat only carefully prepared food. Do not eat raw or undercooked foods. Cook meat and fish avoiding contact with other foods.

  5. Follow the news and instructions from local authorities. If cases have been reported in your area, follow recommendations to reduce the risk of infection and limit movement.
