What is Viral Gastroenteritis?

Viral gastroenteritis is an infection that leads to symptoms like diarrhea, vomiting, stomach cramps, and nausea. It is highly contagious and spreads through contaminated food, water, or close contact with infected individuals.

• Recovery Phase: Symptoms gradually improve, but fatigue and mild digestive issues may persist.

Managing Symptoms
