Signs of Stomach Flu and When to See a Doctor!

Causes and Risk Factors of Stomach Flu (Viral Gastroenteritis)!

Also known as food poisoning or viral gastroenteritis.

Viral gastroenteritis dubbed the "stomach flu" is the second most common illness in the United States. It is not caused by the influenza virus, and it is not a respiratory illness. Instead, the stomach flu is caused by a contagious virus (frequently norovirus or rotavirus) that attacks the intestinal tract and causes inflammation, vomiting, and diarrhea.
