Understanding Viral Gastroenteritis: The Basics of Stomach Flu
Viral gastroenteritis, commonly known as the stomach flu, is an inflammation and irritation of the intestines caused by various viruses. This highly contagious illness can spread rapidly through close contact with infected individuals or via contaminated food, water, or surfaces. Despite its colloquial name, it’s not related to influenza.
The most prevalent viruses responsible for viral gastroenteritis include norovirus and rotavirus. These pathogens can easily proliferate in crowded environments such as childcare facilities, schools, nursing homes, and cruise ships. Understanding the nature of this illness is crucial for effective prevention and management.
How does viral gastroenteritis spread?
Viral gastroenteritis transmits through several routes:
- Consuming contaminated food or water
- Close contact with infected individuals
- Sharing utensils or personal items with someone carrying the virus
- Touching contaminated surfaces
- Poor hand hygiene, especially among food handlers
The ease of transmission underscores the importance of proper hygiene practices and awareness in preventing outbreaks.
Recognizing the Symptoms of Stomach Flu
Symptoms of viral gastroenteritis typically manifest shortly after infection, although the onset can vary depending on the specific virus. For instance, norovirus symptoms usually appear within 12 to 48 hours, while adenovirus symptoms may take 3 to 10 days to develop.
What are the primary symptoms of viral gastroenteritis?
The main symptoms include:
- Loose, watery diarrhea (more than 3 times per day)
- Fever or chills
- Nausea and vomiting
- Headache, muscle aches, or joint pain
- Sweating or clammy skin
- Abdominal cramps and pain
- Loss of appetite
It’s important to note that diarrhea caused by viral gastroenteritis is typically not bloody. The presence of blood in stool could indicate a more severe infection and requires immediate medical attention.
How long do symptoms of viral gastroenteritis last?
The duration of symptoms can vary depending on the causative virus, ranging from 1 to 14 days. In the case of norovirus, the most common cause of viral gastroenteritis, most people start feeling better within 1 to 3 days of symptom onset, according to the Centers for Disease Control and Prevention (CDC).
Common Viruses Causing Stomach Flu
Several viruses can cause viral gastroenteritis, each with its own characteristics and patterns of infection. Understanding these pathogens can help in recognizing and managing the illness more effectively.
Which viruses are primarily responsible for viral gastroenteritis?
The most common viruses causing stomach flu include:
- Norovirus
- Rotavirus
- Adenovirus
- Astrovirus
Norovirus: The Leading Cause of Viral Gastroenteritis
Norovirus is highly contagious and can affect individuals of any age. It’s the primary cause of gastroenteritis outbreaks worldwide, with most cases in the United States occurring between November and April. Norovirus spreads through contaminated food, water, surfaces, or direct contact with infected individuals.
Symptoms of norovirus infection include:
- Nausea
- Diarrhea
- Fever
- Body aches
Rotavirus: A Major Concern for Young Children
Rotavirus commonly affects infants and young children, who can then transmit the virus to other children and adults. It’s usually contracted and transmitted orally, with symptoms typically appearing within 2 days of infection. Rotavirus is a significant cause of severe diarrheal illness in young children worldwide.

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.

Symptoms of stomach flu
Abdominal pain: symptom of stomach flu, which is manifested by soreness and discomfort in the abdomen. The pain is usually localized and may be accompanied by spasms.
Diarrhea: is common with intestinal flu and is one of the most common symptoms. Diarrhea may be associated with loose or semi-liquid stools and frequent calls to the toilet.
Nausea and vomiting: are common symptoms of intestinal flu and often appear in the first few hours after infection. Nausea and vomiting may be accompanied by abdominal discomfort and weakness.

Dehydration: intestinal flu can cause desiccation associated with frequent diarrhea. Dehydration can lead to weakness, headache, and low blood pressure.
How the stomach flu is transmitted
The stomach flu is a viral disease that is transmitted through the fecal-oral route. This means that the infection is transmitted through contact with infected feces or through the oral cavity.
The most common mode of transmission of intestinal flu is through poor hygiene. For example, if an infected person does not wash their hands before eating, after using the toilet, or after contact with animals, they can transmit the virus to other people.
Influenza can also be spread through contaminated objects and surfaces such as doorknobs, sinks, cutlery, which can be contaminated with bacteria and viruses. If a person touches such a contaminated object and then puts their hands or objects into their mouth, they may be infected with the intestinal flu.
There is also the possibility of transmission through contact with infected animals such as rabbits, rodents, birds and other animals that may contain bacteria and viruses that cause intestinal flu.
It is important to remember that stomach flu is a highly contagious disease that can spread quickly and easily. The best way to protect yourself from infection is to practice good hygiene: wash your hands with soap and water, avoid shared items (cereals, cutlery), stay home when you are sick, and go to the doctor.

How to prevent stomach flu?
Practice good hand hygiene
Clean hands are the best way to prevent stomach flu. Wash your hands before eating, after using the toilet, after contact with sick people, and after contact with animals. Use soap and warm water to wash your hands, then dry your hands with a towel. If you don’t have access to soap and water, use alcohol-based gel or wet wipes.
Avoid contaminated food
Most cases of stomach flu are caused by eating contaminated food. Avoid foods that spoil quickly, such as meat, eggs, fish, and dairy products. Also cook meat, poultry, and eggs before eating them.
Do not touch sick animals
Animals can carry the flu virus. You may have heard of outbreaks of intestinal flu in animals such as pigs and birds. If you visit farms, zoos, or other places where animals can be observed, avoid direct contact with them. Don’t touch them unnecessarily, don’t kiss them, and don’t hold them in your arms.
Stay home if you are sick
Stay home if you have flu symptoms such as diarrhea and vomiting. Also avoid contact with other people so as not to infect them.
Take precautionary measures while traveling
If you are traveling abroad, please pay attention to local public health and advice on preventing the flu. It is generally recommended to drink bottled water, avoid ice, spicy and fried foods, and contact with infected people.
Diagnosis of intestinal flu
Diagnosis of intestinal influenza is an important step in the treatment of this disease. The most common diagnostic method is a stool test for the presence of the virus. To do this, a stool sample is taken and laboratory analysis is carried out. This analysis allows you to detect the presence of the virus in the intestines of the patient.
For a complete diagnosis of intestinal flu, a specialist can use other research methods, such as a blood test. This method allows you to determine the presence of antibodies in the blood, which indicates that the virus has already been in the human body.
In addition, an important diagnostic step is to ask the patient about symptoms. Describing the symptoms that accompany the disease will help the doctor determine which type of flu the patient is suffering from.
In general, the diagnosis of intestinal flu requires a comprehensive approach. The patient undergoes laboratory tests, and also gives a description of the symptoms of the disease. This approach will allow diagnosing the disease accurately and prescribing the correct treatment.
Treatment of intestinal influenza
Symptomatic treatment
The main method of treatment of intestinal influenza is symptomatic, aimed at relieving the symptoms of the disease. First of all, it is necessary to eliminate dehydration – it is imperative to drink liquids, primarily water. It is recommended to monitor nutrition and increase fluid intake. It is also important to eat a balanced diet, avoid fatty and fried foods and eat easily digestible foods. To improve well-being, you can use antipyretic, anti-inflammatory and analgesic drugs prescribed by a doctor.
Etiotropic therapy
Etiotropic therapy is aimed at the destruction of the causative agent of intestinal influenza. For this, a number of drugs are used – antiviral, antibacterial and antiparasitic. The choice of drug depends on the type of pathogen and the degree of damage to the body. It is not recommended to select drugs on your own, you need to consult a doctor for qualified help.
Physiotherapy and anti-inflammatory treatments
Physiotherapy can help restore the body’s defenses and speed up the healing process. For example, ozone therapy helps to improve blood circulation and immune functions of the body, and ultraviolet rays therapy has a pronounced anti-inflammatory effect. However, the use of physiotherapy must be agreed with the attending physician.

ENTEROVIRUS INFECTION
Enteroviruses are so named because after infection they multiply initially in the gastrointestinal tract. Despite this, they usually do not cause intestinal symptoms, most often they actively spread and cause symptoms and diseases of such organs as: heart, skin, lungs, brain and spinal cord. Enteroviruses are found throughout the world, but infection most often occurs in areas with poor hygiene and high overcrowding. The virus is most often transmitted by the fecal-oral route, as well as through contaminated food or water. Inhalation of certain strains of the virus into the body can lead to respiratory diseases. Breast milk contains antibodies that can protect newborns. The incubation period for most enteroviruses is 2 to 14 days. In temperate regions, infections occur mainly in summer and autumn.
Enterovirus most often enters the human body through the gastrointestinal tract (GIT) or respiratory tract. Once in the gastrointestinal tract, viruses stop in the local lymph nodes where they begin the first stage of reproduction. Around the third day after infection, the viruses enter the bloodstream and begin to circulate throughout the body. On the 3-7th day, viruses with blood can enter the organ systems where the second stage of reproduction can begin and, as a result, cause various diseases. The production of antibodies to the virus occurs during the first 7-10 days.
Symptoms and signs of enterovirus infection
Enteroviruses cause a huge number of infections per year. More than 90% of these cases are either asymptomatic or cause a nonspecific febrile illness. Usually the range of symptoms is very wide, but in most cases it almost always includes: fever (increase in body temperature up to 39-40 ° C), general weakness, headache, muscle pain and gastrointestinal symptoms.
Enteroviruses entering the human body can cause several symptoms.
- Runny nose and stuffy nose and sinuses , sore nose, sore throat, earache, difficulty swallowing, loss of smell or taste.
- Nausea, indigestion, reflux, bloating , upper and lower abdominal pain, cramps, constipation alternating with diarrhoea.
- Rapid weight loss due to indigestion and reduced calorie intake or weight gain due to inactivity.
- Numbness in limbs , muscle twitching and spasms. Facial tingling and numbness may be observed.
- Miscellaneous headaches (acute, aching, throbbing).
- Pain in bones, muscles and joints . Leg pain is quite common.
- Chest pain and tightness, palpitations .
- Cough, shortness of breath, wheezing .
- Heart rhythm disorder (arrhythmias) or tachycardia (palpitations)
- Intermittent fever – characterized by a rapid, significant increase in temperature (38-40 ° C), which lasts for several hours, and then is replaced by its rapid fall to normal values), chills and severe night sweats.
- Blurred vision, reduced visual acuity .
- Blisters or ulcerations in the mouth, pharynx and, in women, in the vagina/cervix .
- Psychological problems – Anxiety or depression.
- Problems with concentration . Cognitive problems, short-term memory problems.
- Sleep disturbance .
- Seizures are rare but do occur.
- Swollen lymph nodes in the neck and armpits
- Rash
It is impossible to talk about any specific symptoms characteristic of the entire group of enteroviruses in addition to those listed above, but it is possible to group the symptoms manifested in complications of enterovirus infection:
Treatment of enterovirus infection
. The basis is symptomatic and supportive treatment. Bed rest, plenty of fluids, vitamins, antipyretic in case of high temperature.
