Viral Gastroenteritis
Viral gastroenteritis, commonly known as the stomach flu, is an infection of the digestive tract caused by a virus. The most common types of viruses that cause gastroenteritis are norovirus and rotavirus.
Symptoms of viral gastroenteritis can include:
abdominal pain or cramping
Symptoms can range from mild to severe and last from a few days to a week or longer. The virus is usually spread through contact with contaminated food, water, or surfaces or close contact with an infected person. Good hygiene, such as washing hands thoroughly and frequently, can help prevent the spread of the virus.
There is no specific treatment for viral gastroenteritis, and antibiotics are ineffective against viruses. Treatment is focused on managing symptoms and preventing dehydration. Drinking clear fluids such as water, sports drinks, or clear broth can help replace fluids and electrolytes lost due to vomiting and diarrhea. Over-the-counter medications such as anti-nausea drugs, antidiarrheal agents, and pain relievers may also be used to manage symptoms.
In severe cases of dehydration, hospitalization and intravenous (IV) fluids may be necessary. It's important to seek medical attention if symptoms are severe, if there is blood in the stool or vomit, or if symptoms last longer than a few days.
