Diarrhea fever and body aches. Norovirus Symptoms: Recognizing and Treating the Stomach Flu at Home
What are the main symptoms of norovirus. How long does the stomach flu typically last. Can you differentiate between stomach flu and food poisoning. What are effective home remedies for treating norovirus symptoms. How does the stomach flu spread and how can it be prevented.
Understanding Norovirus: The Common Culprit Behind Stomach Flu
Norovirus, often referred to as the “stomach flu,” is a highly contagious viral infection that affects millions of people worldwide each year. Despite its nickname, it’s not related to influenza. Instead, norovirus is the leading cause of gastroenteritis, an inflammation of the stomach and intestines that results in a range of uncomfortable symptoms.
Norovirus accounts for more than 50% of all gastroenteritis cases, making it crucial to understand its symptoms, transmission, and treatment options. While other viruses like rotavirus and bacteria such as salmonella and E. coli can also cause similar symptoms, norovirus remains the most common culprit.
Key Facts About Norovirus
- Responsible for over 50% of gastroenteritis cases
- Highly contagious and can survive on surfaces for days
- Not prevented by the flu shot
- Symptoms can appear as quickly as 12 hours after exposure
Identifying Stomach Flu Symptoms: What to Look Out For
Recognizing the symptoms of norovirus is essential for proper management and preventing its spread. The primary symptoms of stomach flu include:
- Stomach pain
- Nausea
- Vomiting
- Diarrhea
- Low-grade fever
- Chills
- Muscle aches
These symptoms can vary in intensity and duration from person to person. How long does the stomach flu typically last? The duration of symptoms can range from one to 14 days, with most cases resolving within a few days.
Onset and Duration of Symptoms
Symptoms of norovirus can begin as soon as 12 hours after exposure to the virus. This rapid onset is one of the characteristics that distinguishes it from some other gastrointestinal illnesses. The severity and duration of symptoms can depend on factors such as age, overall health, and immune system strength.
Stomach Flu vs. Food Poisoning: Unraveling the Confusion
Given the similarity in symptoms, it’s common for people to confuse stomach flu with food poisoning. How can you differentiate between stomach flu and food poisoning? While both conditions can cause vomiting, diarrhea, abdominal discomfort, and fever, there are some key differences to consider:
Timing of Symptom Onset
Food poisoning symptoms typically appear within hours of consuming contaminated food or drink. If you can recall eating something questionable and symptoms develop shortly after, food poisoning is more likely. Stomach flu symptoms, on the other hand, usually take 24-48 hours to manifest after exposure to the virus.
Affected Population
If multiple people who shared the same meal experience similar symptoms simultaneously, it’s more likely to be food poisoning. Stomach flu, being highly contagious, can affect individuals who haven’t necessarily eaten the same foods but have been in close contact with an infected person.
Duration of Illness
Food poisoning typically resolves faster than stomach flu, often within 24-48 hours. Norovirus symptoms can persist for several days, sometimes up to two weeks in severe cases.
The Spread of Norovirus: Understanding Transmission and Prevention
Norovirus is notorious for its high contagiousness and ability to spread rapidly through communities. How does the stomach flu spread and how can it be prevented? The primary mode of transmission is the fecal-oral route, meaning that virus particles from infected feces or vomit find their way into the mouths of uninfected individuals.
Common Transmission Routes
- Direct contact with an infected person
- Touching contaminated surfaces and then touching the mouth
- Consuming contaminated food or water
- Inhaling airborne particles from vomit
One of the challenges in preventing norovirus spread is its resilience. Unlike many viruses, noroviruses can survive on surfaces for days, making thorough cleaning and disinfection crucial in controlling outbreaks.
Effective Prevention Strategies
- Frequent and thorough handwashing with soap and water
- Proper food handling and preparation techniques
- Thorough cleaning and disinfection of contaminated surfaces
- Avoiding close contact with infected individuals
- Staying home when sick to prevent spreading the virus
Home Remedies for Norovirus: Effective Ways to Manage Symptoms
While there’s no specific medical treatment for norovirus, several home remedies can help alleviate symptoms and promote recovery. What are effective home remedies for treating norovirus symptoms? Here are some strategies recommended by healthcare professionals:
1. Hydration is Key
Preventing dehydration is crucial when battling norovirus. Drink plenty of fluids, including water, clear broths, and oral rehydration solutions. For adults, sports drinks can help replenish electrolytes. Children can benefit from pediatric electrolyte solutions like Pedialyte.
2. Gradual Diet Reintroduction
As your appetite returns, slowly reintroduce easily digestible foods. Start with bland, low-fiber options such as:
- Bananas
- Rice
- Applesauce
- Toast
- Crackers
3. Rest and Recovery
Allow your body time to heal by getting plenty of rest. Avoid strenuous activities until you’ve fully recovered.
4. Over-the-Counter Medications
For adults under 65, over-the-counter medications like loperamide (Imodium) or bismuth subsalicylate (Pepto-Bismol) can help manage diarrhea. However, it’s essential to consult a healthcare provider before using these medications, especially for children or older adults.
Norovirus vs. COVID-19: Navigating Symptom Overlap
In the context of the ongoing COVID-19 pandemic, it’s important to distinguish between norovirus and COVID-19 symptoms. While both can cause gastrointestinal issues, there are some key differences to be aware of:
Symptom Progression
About 20% of COVID-19 cases involve gastrointestinal symptoms like nausea, vomiting, and diarrhea. However, these symptoms typically develop in the first couple of days and are often followed by respiratory symptoms such as fever, cough, and fatigue.
Duration and Additional Symptoms
Norovirus symptoms usually resolve within a few days, while COVID-19 can persist for a longer period. Additionally, COVID-19 often involves respiratory symptoms and loss of taste or smell, which are not typical of norovirus infections.
When to Seek Medical Attention
If you experience gastrointestinal symptoms followed by respiratory issues or other COVID-19 symptoms, it’s advisable to consult a healthcare provider and consider getting tested for COVID-19.
Preventing Norovirus Outbreaks: Community and Institutional Strategies
Given the highly contagious nature of norovirus, prevention strategies are crucial, especially in communal settings like schools, healthcare facilities, and cruise ships. What measures can be taken to prevent norovirus outbreaks in these environments?
Enhanced Cleaning Protocols
Implement rigorous cleaning and disinfection protocols, paying special attention to high-touch surfaces. Use EPA-approved disinfectants effective against norovirus.
Hand Hygiene Campaigns
Promote proper hand hygiene through educational campaigns and by providing easy access to handwashing facilities and alcohol-based hand sanitizers.
Isolation Policies
Establish and enforce policies for isolating individuals with symptoms of gastroenteritis to prevent the spread of the virus.
Food Safety Measures
In food service settings, implement strict food handling and preparation guidelines to minimize the risk of contamination.
Long-Term Health Impacts of Norovirus Infections
While norovirus infections are typically acute and self-limiting, recent research has begun to explore potential long-term health effects. Are there any lasting impacts of norovirus infections?
Gut Microbiome Alterations
Some studies suggest that norovirus infections may lead to temporary changes in the gut microbiome, potentially affecting digestive health and immunity.
Post-Infectious Irritable Bowel Syndrome
A small percentage of individuals may develop post-infectious irritable bowel syndrome (IBS) following a severe norovirus infection, leading to ongoing gastrointestinal symptoms.
Immune System Effects
Research is ongoing to understand how repeated norovirus infections might impact long-term immune function, particularly in vulnerable populations.
While these potential long-term effects are still being studied, they underscore the importance of prevention and proper management of norovirus infections.
Understanding norovirus, its symptoms, and effective management strategies is crucial for individual health and public health efforts. By recognizing the signs early, implementing proper hygiene practices, and following appropriate home care methods, we can minimize the impact of this common yet disruptive illness. As research continues to uncover more about norovirus and its effects, staying informed and adhering to prevention guidelines remains our best defense against this persistent pathogen.
Have the Stomach Flu? 4 Ways to Treat Symptoms at Home
There’s almost nothing worse than being bent over a toilet throwing up. And, sadly, it can be hard to know what caused you to be there in the first place. Kelli Miller, ANP, UnityPoint Health, lists the symptoms of the stomach flu and how long it lasts, plus ways to feel better, so you can get out of the bathroom and get back to normal.
Stomach Flu Symptoms
Miller says it’s easy to get confused about the difference between influenza, or “the flu,” and gastroenteritis, better known as “the stomach flu.” The stomach flu is caused by a number of viruses, mainly norovirus, which accounts for more than 50 percent of all cases, and others, like rotavirus. Bacteria, such salmonella and E. coli, can also be to blame. Getting the flu shot does not prevent you from getting the stomach flu, but it does prevent you from getting influenza.
“Stomach flu symptoms include stomach pain, nausea, vomiting and diarrhea,” Miller says. “A low-grade fever, chills and muscle aches aren’t uncommon to experience as well. Symptoms can start as little as 12 hours after exposure.”
These symptoms can last anywhere from one to 14 days, and unfortunately, the stomach flu is extremely contagious.
“The stomach flu is spread by the fecal-oral route, which means the viruses from infected feces or vomit find their way into our mouths from either touching a contaminated surface and then touching your face or eating/drinking contaminated foods and/or water. Compared to other viruses, noroviruses can live for days on household surfaces, which is why they spread easily,” Miller says.
Stomach Flu vs. Food Poisoning
Miller says the clinical symptoms of the stomach flu and food poisoning overlap quite a bit, as you can have vomiting, diarrhea, abdominal discomfort and fever with either one. She says the easiest way to determine the cause of your discomfort is to look back at your recent history.
“If your symptoms are caused by food poisoning, they tend to occur within hours after eating something. If you can recall eating something questionable, or if others who ate the same thing as you and have similar symptoms, you probably have food poisoning. If you are the only one who got sick, you more than likely picked up a viral illness,” Miller says.
Stomach Flu vs. COVID-19
To make matters even more confusing, some people with COVID-19 (about 20% according to studies) experience stomach issues including nausea, vomiting and/or diarrhea. Most people with those symptoms usually report developing them in the first couple of days and then go on to experience other respiratory or cold-like symptoms like fever, headache, cough and fatigue.
If you experience nausea, vomiting and/or diarrhea, keep an eye out for other symptoms that may follow. If you notice a progression in the illness, talk with your doctor about getting tested for COVID-19. Remember, if you’re feeling sick, stay home and continue to wash your hands frequently.
How to Treat the Stomach Flu at Home
Miller says there’s often no specific medical treatment for viral gastroenteritis. Antibiotics aren’t effective against viruses and overusing them can contribute to the development of antibiotic-resistant strains of bacteria. She recommends treating the stomach flu with the following self-care steps:
- Keep drinking the right fluids. You’ll need to drink enough fluids to prevent dehydration. In addition to water, older children and adults can drink sports drinks, like Gatorade, Power Aid, while babies and young children can have an oral rehydration solution, such as Pedialyte. If your child is vomiting, you can try to give your child a few teaspoons of fluid every few minutes. Babies who breastfeed can continue to breastfeed. But, you should avoid drinks with increased sugar content, such as juices or sodas, which can make diarrhea worse.
- Eat the right foods. If you don’t have an appetite, you should resort to drinking only liquids for a short period of time. Boiled starches (potatoes, noodles, rice, wheat and oats) and plain cereals with salt are recommended, if you have watery diarrhea. You may also try crackers, bananas, soup and boiled vegetables.
- Avoid heavy foods. On the other hand, you should avoid certain foods until you are feeling better. These include dairy products, caffeine, alcohol, nicotine and fatty or highly-seasoned foods.
- Get plenty of rest. The illness or dehydration can make you feel tired.
“Adults under 65 years old with a new bout of diarrhea, with no fever or blood in bowel movements, can take medicine to stop diarrhea, such as loparmide (Imodium) or bismuth subsalicyclate (Pepto Bismal) for one to two days, if they’re not allergic to these medications. Children and adults over the age of 65 should check with their health care provider before taking any over-the-counter medicines,” Miller says.
As contagious as it is, keeping your family from catching the stomach flu can be tricky. Miller offers these tips to protect against the viral infections that cause gastroenteritis:
- Immunize little ones. Infants can be immunized with the rotavirus vaccine. This is offered at 2, 4 and 6 months old during well-child visits.
- Simply wash your hands. Wash your hands often to stop the spread of germs. Hand sanitizer works after being in public as well.
- Give your home the once-over. Use household cleaning products to disinfect surfaces and objects, like countertops, doorknobs, handles, sinks, toilets, computer keyboards and phones.
- Separate your laundry loads. Wash laundry of those recovering from the stomach flu in different loads than the rest of your family.
- Keep your distance. Try to keep your children, especially newborns, away from anyone who is sick. If someone in your family is sick, stay home and do not go to work, school or day care. You should be symptom-free for 48 hours before returning.
When the Stomach Flu Requires a Doctor
While most stomach illnesses pass on their own, there are cases when medical attention is necessary. Miller recommends watching for signs of severe dehydration:
- Increased thirst
- Dry mouth
- Headache
- Confusion
- Increased heart rate over 100 beats per minute
- Increased breathing rate
- Dizziness, including when standing from a sitting or laying position
- Passing out
- Fatigue
- Dark yellow or amber colored urine
- No urination within the past six to eight hours (during the day)
In addition to severe dehydration, Miller also says the following are causes for concern, and if you experience these, contact your provider:
- Bloody stool/rectal bleeding or blood in vomit
- Vomiting for more than 24 hours
- Fever greater than 104 degrees
- Weight loss
- Severe abdominal pain
- Prolonged symptoms lasting more than a week
- Are currently pregnant
Lastly, call your baby’s doctor right away if your baby:
- Has vomiting lasting several hours
- Hasn’t had a wet diaper in six hours
- Has bloody stools or severe diarrhea
- Has a sunken soft spot (fontanel) on the top of his or her head
- Has a dry mouth or cries without tears
- Is unusually sleepy, drowsy or unresponsive
If any of these symptoms are present, evaluation by a health care professional is needed right away, and IV hydration may need to be administered or possible admission to the hospital.

Viral gastroenteritis can cause nausea and vomiting. You can get the virus that causes it from other people or through contaminated foods, drinks, or surfaces. Washing your hands often may help prevent it.
Viral gastroenteritis is an inflammation and irritation of your intestines caused by one of a number of viruses, most commonly norovirus or rotavirus. This illness is also known as the stomach flu.
This highly contagious illness spreads through close contact with people who have the virus or through contaminated food or water.
It can easily spread in close quarters, such as:
- childcare facilities
- schools
- nursing homes
- cruise ships
This article will help you understand more about viral gastroenteritis including symptoms, causes, treatment, and prevention.
Symptoms of gastroenteritis usually begin shortly after infection. For example, symptoms caused by norovirus typically develop within 12 to 48 hours. Symptoms from adenoviruses may be delayed 3 to 10 days after contact.
Depending on which type of virus you’ve contracted, symptoms can last anywhere from 1 to 14 days. Symptoms often start suddenly over the course of 1 or 2 hours.
Symptoms can include:
- loose, watery diarrhea more than 3 times per day
- fever or chills
- nausea and vomiting
- headache, muscle aches, or joint aches
- sweating or clammy skin
- abdominal cramps and pain
- loss of appetite
Diarrhea caused by viral gastroenteritis isn’t usually bloody. Blood in your stool could be a sign of a more severe infection.
You should seek emergency medical treatment if:
- diarrhea has lasted for 2 days or more without getting less frequent
- your infant develops diarrhea
- blood is present in your diarrhea
- you show or see signs of dehydration, such as dry lips or dizziness
In addition to the above symptoms, you should seek emergency attention for your child if they have the appearance of sunken eyes or if they aren’t making tears when they cry.
Viral gastroenteritis is caused by a number of different viruses. It’s easy for these viruses to spread in group situations. Some of the ways the virus is transmitted include:
- eating contaminated food or drinking contaminated water
- being in close contact with someone who has the virus
- sharing utensils or other items with someone who has the virus
- touching contaminated surfaces
- not washing hands properly, especially food handlers
Viral gastroenteritis affects people of all ages all over the world. But some factors can increase the risk of contracting viral gastroenteritis. People who are at a higher risk include:
- children under the age of 5
- older adults, especially those who live in nursing homes or assisted living facilities
- people with a compromised or weakened immune system
- those who are often in group settings, such as schools, dormitories, day care, religious gatherings, and other indoor group settings
Other factors that may increase the risk of becoming ill with viral gastroenteritis include:
- being malnourished, especially low levels of vitamin A or zinc
- recent travel to developing countries
- antibiotic or antacid use
- anal intercourse
Several different types of viruses can cause viral gastroenteritis. The most common include:
- norovirus
- rotavirus
- adenovirus
- astrovirus
Let’s look at each of these viruses in more detail.
Norovirus
Norovirus is highly contagious and can affect anyone at any age. It spreads through contaminated food, water, and surfaces, or by people who have the virus. Norovirus is common in crowded spaces.
Norovirus is the leading cause of gastroenteritis in the United States and worldwide. Most outbreaks in the United States occur between November and April.
Symptoms include:
- nausea
- diarrhea
- fever
- body aches
According to the Centers for Disease Control and Prevention (CDC), most people who become ill with norovirus start to feel better within 1 to 3 days of symptom onset.
Rotavirus
Rotavirus commonly affects infants and young children. Those who contract it can then pass the virus to other children and adults. It’s usually contracted and transmitted via the mouth.
Symptoms typically appear within 2 days of infection and include:
- vomiting
- loss of appetite
- watery diarrhea that lasts anywhere from 3 to 8 days
A rotavirus vaccine was approved for infants in 2006. Early vaccination is recommended to prevent severe rotavirus illnesses in infants and small children.
Adenovirus
The adenovirus affects people of all ages. It can cause several types of illness, including gastroenteritis. The adenovirus can also cause common cold-like symptoms, bronchitis, pneumonia, and pink eye (conjunctivitis).
Children in daycare, especially those under 2 years of age, are more likely to get adenovirus.
Adenovirus is passed through the air via sneezing and coughing, by touching contaminated objects, or by touching the hands of someone with the virus.
Symptoms associated with adenovirus include:
- sore throat
- pink eye
- fever
- coughing
- runny nose
Most children will feel better within a few days of experiencing adenovirus symptoms. However, symptoms such as pink eye may last longer than a few days.
Astrovirus
Astrovirus is another virus that commonly causes gastroenteritis in children. Symptoms associated with astrovirus include:
- diarrhea
- headache
- mild dehydration
- stomach pain
The virus most often affects people in late winter and early spring. It’s transmitted through contact with a person who has the virus or via an infected surface or food.
Symptoms usually appear within 2 to 3 days after initial exposure, and the virus will usually go away within 1 to 4 days.
The main complication of viral gastroenteritis is dehydration, which can be quite severe in babies and young children. Viral gastroenteritis accounts for over 200,000 childhood deaths worldwide per year.
Other complications of viral gastroenteritis include:
- nutritional imbalances
- body weakness or fatigue
- muscle weakness
Dehydration can be life threatening. Call your doctor if you or your child have these symptoms:
- diarrhea lasting more than a few days
- blood in the stool
- confusion or lethargy
- dizziness or feeling like you’re going to faint
- nausea
- dry mouth
- an inability to produce tears
- no urine for more than 8 hours or urine that is dark yellow or brown
- sunken eyes
- sunken fontanel on an infant’s head
Dehydration that accompanies viral gastroenteritis can lead to several complications of its own. These include:
- brain swelling
- coma
- hypovolemic shock, a condition that occurs when your body doesn’t have enough fluid or blood
- kidney failure
- seizures
To prevent complications, get immediate medical attention if you or your child have symptoms of dehydration.
Most of the time, your medical history and physical exam are the basis for diagnosis, especially if there’s evidence that the virus is spreading through your community.
Your doctor may also order a stool sample to test for the type of virus, or to find out if your illness is caused by a parasitic or bacterial infection.
The main focus of treatment is to prevent dehydration by drinking plenty of fluids. In severe cases, hospitalization and intravenous fluids may be necessary.
Over-the-counter oral rehydration solutions (OHS), such as Pedialyte, can be helpful in mild cases. These solutions are easy on your child’s stomach, and contain a balanced mixture of water and salts to replenish essential fluids and electrolytes.
These solutions are available at local pharmacies and don’t require a prescription. However, you should follow the instructions carefully.
Antibiotics have no effect on viruses. Check with your physician before taking any over-the-counter medications.
Shop online for oral rehydration solutions such as Pedialyte and oral electrolyte products.
Treating diarrhea and vomiting
Diarrhea can be treated in adults with over-the-counter medications such as loperamide (Imodium) or bismuth subsalicylate (Pepto-Bismol).
Your doctor may also prescribe probiotics to replace the healthy bacteria that’s lost during diarrhea or they may prescribe medications to treat severe vomiting.
What to eat and what to avoid
As you start to feel better and reintroduce foods into your diet, it’s best to opt for bland foods, such as:
- rice
- potatoes
- toast
- bananas
- applesauce
These foods are easier to digest and less likely to cause further stomach upset. Until you’re feeling better, you may want to avoid some types of foods, such as:
- fatty or fried foods
- caffeine
- alcohol
- sugary foods
- dairy products
Self-care steps
If you have viral gastroenteritis, consider these self-care measures to help ease your symptoms and prevent dehydration:
- Drink extra fluids with and between meals. If you have difficulty, try drinking very small amounts of water or sucking on ice chips.
- Avoid fruit juices. These don’t replace the minerals that you’ve lost and can actually increase diarrhea.
- Electrolytes. Children and adults can consume sports drinks to replenish electrolytes. Younger children and infants should use products formulated for children, such as OHS.
- Limit portion sizes. Try to eat food in smaller amounts to help your stomach recover.
- Get lots of rest. Prioritize getting at least 7 to 8 hours of sleep each night. Don’t exert yourself until you feel that you have your usual level of energy and strength.
- Medications. Check with your doctor before taking medications or giving them to children. Never give aspirin to children or teenagers with a viral illness. This can cause Reye’s syndrome, a potentially life threatening condition.

In addition to rehydrating and resting, there are some natural and home remedies that may help you relieve the symptoms of viral gastroenteritis.
Heating pad or heat pack
If you have abdominal pain, try applying a low-temperature heating pad or a warm heat pack to your stomach. Cover the heating pad with a cloth and don’t leave it on for more than 15 minutes at a time.
The heat can help relax the muscles in your digestive tract and keep them from spasming.
Shop online for heating pads and heat packs.
Brown rice water
Some parents serve rice water to their children. This is the water that remains after boiling brown rice. It’s high in electrolytes and can help with rehydration.
To make rice water:
- Boil 1 cup of rice and 2 cups of water for about 10 minutes until the water becomes cloudy.
- Strain the rice and keep the water.
- Cool the rice water before serving.
Ginger
Products containing ginger, such as ginger ale or ginger tea, may help soothe an upset stomach.
A 2019 review of studies found that a divided daily dose of 1,500 milligrams of ginger taken in two parts throughout the day may help reduce nausea. More research needs to be done on ginger’s ability to treat other gastrointestinal symptoms.
Shop online for ginger ale and ginger tea.
Mint
Mint may also have anti-nausea properties similar to those of ginger. Sipping a soothing mint tea may help you feel better.
Studies have found that peppermint oil may help relax the muscles in your gut. It also has anti-microbial and anti-inflammatory properties.
Shop online for mint tea.
Yogurt or kefir
Although dairy products should be avoided when you have your most acute symptoms, eating unflavored yogurt with live active cultures or drinking kefir may help restore your body’s natural bacterial balance after illness.
Shop online for plain yogurt and kefir.
Viral gastroenteritis can spread easily. However, there are some steps you can take to lower your risk of contracting the virus or passing it to others.
Prevention tips
- Wash your hands often, especially after using the bathroom and before food preparation. If necessary, use hand sanitizer until you can access soap and water.
- Don’t share kitchen utensils, plates, or towels if someone in your household is sick.
- Don’t eat raw or undercooked foods.
- Wash fruits and vegetables thoroughly.
- Take special precautions to avoid contaminated water and food when traveling. Avoid ice cubes and use bottled water whenever possible.
- Ask your doctor if you should have your infant vaccinated against rotavirus. There are two vaccines, and they’re generally started around 2 months old.

Viral gastroenteritis is an inflammation and irritation of your intestines caused by one of several types of viruses.
Vomiting and diarrhea are among the most common symptoms. You can get viral gastroenteritis from other people or through contaminated foods, drinks, or surfaces.
Generally, viral gastroenteritis symptoms come on suddenly and pass quickly. If diarrhea lasts longer than 48 hours, be sure to follow up with your doctor.
It’s also a good idea to get medical attention if your infant or young child develops diarrhea because it can lead to serious complications due to dehydration.
Enteroviral infection
09/18/2017
Enterovirus infection is a multiple group of acute infectious diseases that can affect children and adults when infected with viruses of the Enterovirus genus. The insidiousness of the causative agents of enterovirus infection is that they can cause various forms of clinical manifestations, from mild malaise to serious damage to the central nervous system. With the development of an enterovirus infection, the symptoms are characterized by a feverish state and a wide variety of other signs caused by damage to the respiratory system, gastrointestinal tract, kidneys, central nervous system and other organs.
How the infection spreads:
The main route of transmission of enterovirus infection is fecal-oral .
Household contact , through household items, contaminated hands, if personal hygiene is not observed.
Airborne if the pathogen multiplies in the respiratory tract, when coughing, sneezing.
Waterway – infection can occur when vegetables and fruits are watered with contaminated sewage, as well as when swimming in open contaminated water bodies, according to some reports, even water in coolers is a source of enterovirus infection.
If a pregnant woman is infected with an enterovirus infection, a vertical route of the pathogen’s transmission to the child is also possible.
Enterovirus infection is characterized by summer-autumn seasonality, a person has a very high natural susceptibility, and after the illness, type-specific immunity is maintained for several years.
The incubation period of any enteroviral infections is no more than 2-7 days.
All diseases that can be caused by enteroviruses according to the severity of the inflammatory process can be conditionally divided into 2 groups:0017 Serious diseases
These include acute paralysis, hepatitis, serous meningitis in children and adults, pericarditis, myocarditis, neonatal septic-like diseases, any chronic infections in HIV-infected people (HIV infection: symptoms, stages).
Less severe diseases
Conjunctivitis, three-day fever without rash or with rash, herpangina, vesicular pharyngitis, pleurodynia, uveitis, gastroenteritis. Enterovirus D68 can occur with severe cough and bronchopulmonary obstruction.
Symptoms:
Signs of SARS . Children develop perspiration, sore throat, sometimes runny nose, cough, fever. The temperature is high at the first stages, then decreases and after 2-3 days it jumps sharply again. This phenomenon is called “enterovirus fever”. It lasts, as a rule, 3 days, the child will feel unwell. During this period, diarrhea, vomiting, nausea sometimes appear, which can stop abruptly.
Rash . This manifestation of the disease is called “exanthema”. A rash appears on the second day after the temperature rises. As a rule, it is localized on the neck, legs, arms, face, back, chest. Outwardly, it looks like small red dots on the skin, identical to the manifestation of measles. Sometimes the rash is localized in the mouth, throat, looks like bubbles filled with liquid, which then turn into sores.
Muscle pain . Enterovirus infection in some cases affects muscle tissue. It is localized more often in the chest, abdomen, much less often in the back, arms, legs. Deterioration of the condition is manifested by movement, the pain has a paroxysmal character. The duration can be several minutes and up to half an hour. If you do not start timely therapy, muscle pain will become chronic.
Diarrhea, vomiting. Often manifested in children under 2 years of age when the body is affected by an enterovirus infection. Sometimes the symptom is accompanied by bloating, pain. Diarrhea can last for several days. The main task of parents during this period is to restore fluid deficiency in time.
Additional symptoms of enterovirus infection:
drowsiness, lethargy;
abdominal pain;
loss of appetite;
swelling of the extremities;
general malaise;
dehydration;
conjunctivitis, redness of the eyes, lacrimation;
enlargement of the lymph nodes.
In healthy adults with strong immunity, enterovirus infection cannot develop to severe pathological processes, and most often it is completely asymptomatic, which cannot be said about young children, especially newborns and adults weakened by other diseases, such as HIV infection, oncological diseases, tuberculosis.
To prevent the disease of enterovirus infection, it is necessary to observe preventive measures:
Use guaranteed safe water and drinks (boiled water and drinks in factory packaging).
Eat foods that have been heat treated.
Thoroughly wash fruits and vegetables with safe water and then rinse with boiling water.
When swimming in ponds and pools, do not allow water to enter the oral cavity.
Follow the basic rules of personal hygiene.
You should avoid visiting mass events, places with a large number of people (public transport, cinemas, etc.).
Wet cleaning of residential premises is recommended at least 2 times a day, ventilation of premises.
Under no circumstances should a child visit an organized children’s group (school, preschool institutions) with any manifestations of the disease. At the first signs of illness, you should immediately seek medical help, do not self-medicate!
