Viral gastroenteritis is an intestinal infection characterized by watery diarrhea, stomach cramps, nausea or vomiting, and sometimes fever.
It is commonly spread through contact with an infected person or by consuming contaminated food or water, and it is often referred to as the stomach flu.
While most healthy individuals recover without complications, it can be life-threatening for infants, older adults, and those with weakened immune systems.
There is no specific treatment for viral gastroenteritis, making prevention essential. To reduce the risk, avoid potentially contaminated food and water, and wash your hands thoroughly and frequently.
What are the Causes of Stomach Flu?
A viral infection usually causes stomach flu, though bacteria or parasites can also cause it. The most common culprits include:
Rotavirus: This is the leading cause of severe diarrhea in children.
Norovirus: This highly contagious virus can spread rapidly in communities and often causes outbreaks.
Salmonella: A bacterial infection transmitted through contaminated food and water.
Stomach flu can be easily transmitted through contaminated food, water, or contact with an infected person. Good hygiene is important to prevent the spread of the virus.

What are the Stomach Flu Symptoms?
The symptoms of gastric stomach flu symptoms typically appear within 1-3 days after exposure and may include:
- Nausea and vomiting
- Diarrhea
- Abdominal cramps or stomach ache
- Fever
- Headache
- Fatigue
How Long is Stomach Flu Contagious?
Stomach flu, or viral gastroenteritis, can be contagious before symptoms even appear and remains contagious after recovery.
Typically, a person can spread the virus for 1-3 days after symptoms subside. In some cases, it can be longer, especially if caused by certain viruses like norovirus, making good hygiene essential, such as washing hands frequently and thoroughly.
How Long Does Stomach Flu Last?
The duration of the flu depends on the type of virus causing the infection. Symptoms usually last between 1 to 3 days, but some viruses may cause symptoms to linger for up to 10 days.
The severity of the illness varies from mild to severe, but most people recover within a few days with rest, hydration, and proper care. If symptoms persist longer, it’s important to consult a healthcare provider.

What are the Treatment and Prevention Methods?
While there’s no specific treatment for stomach flu, the goal is to manage the symptoms and prevent dehydration. Here are some tips:
Treatment
Stay hydrated: Drink fluids like water or broth to avoid dehydration.
Eat bland foods: Opt for easy-to-digest foods like toast, crackers, or plain rice.
Rest: Get plenty of rest to allow your body to recover.
Over-the-counter medications: Some medications, such as anti-diarrhea or anti-nausea, may help alleviate symptoms.
Consult a doctor: If symptoms persist or worsen, or if you experience signs of dehydration (such as dizziness, dry mouth, or decreased urine output), it’s important to seek medical advice.
Prevention
To prevent it:
- Wash your hands frequently with soap and water.
- Avoid sharing food or utensils with others.
- Clean and disinfect surfaces regularly.
- Cook food thoroughly to kill harmful bacteria.
- Avoid contact with sick individuals.
In cases where children are diagnosed with stomach flu, these are things to keep in mind:
- Ensure your child receives the rotavirus vaccine, as it’s the leading cause of gastroenteritis.
- Wash hands regularly with warm water and soap, especially after using the bathroom, changing diapers, and before or after handling food.
- Rinse all fruits and vegetables before consumption, and ensure eggs, fish, and meat are fully cooked and getting bacteria.
If diarrhea persists and contains blood, your doctor may recommend tests and antibiotics. You can also request a medical certificate to care for your child at home.
A licensed doctor will assess the child’s condition and symptoms and issue a certificate within 6 hours of submitting the request if necessary.
Conclusion
While stomach flu is typically mild and resolves within a few days, it can be highly contagious and severe in vulnerable populations.
Proper handwashing, safe food handling, and vaccination can reduce the risk of infection. If symptoms persist or worsen, consult a healthcare provider.
