Viral gastroenteritis, commonly known as the stomach flu, presents with several hallmark symptoms, primarily watery diarrhea and vomiting. Other associated symptoms include headache, fever, chills, and abdominal pain. These symptoms typically manifest within 4 to 48 hours following exposure to the virus and typically persist for 1 to 2 days. However, in some cases, symptoms may persist for up to 10 days. It’s essential to stay hydrated and rest during this time, and seek medical attention if symptoms are severe or prolonged.
