Viral gastroenteritis, often called the "stomach flu," is an inflammation of the stomach and intestines caused by viruses. Common viruses include norovirus and rotavirus. Symptoms typically include diarrhea, vomiting, stomach cramps, and sometimes fever. It spreads easily through contaminated food, water, or surfaces. Most cases of viral gastroenteritis are mild and resolve within a few days. Staying hydrated is crucial, as the illness can lead to dehydration. Good hygiene practices, such as frequent handwashing, can help prevent the spread of the viruses responsible for this condition.
