norovirus
Sign in to saveNorovirus, also known as Norwalk virus, is the most common cause of gastroenteritis. The infection, sometimes referred to as the winter vomiting disease, is characterized by non-bloody diarrhea, vomiting, and stomach pain. Fever or headaches may also occur. Symptoms usually develop 24 hours after being exposed, and recovery typically occurs within one to three days. Complications are uncommon, but may include dehydration, especially in the young, the old, and those with other health problems.
AI overview
Norovirus is a highly common virus that causes gastroenteritis, characterized by symptoms like vomiting, diarrhea, and stomach pain that typically appear within a day of exposure and resolve within a few days. While most people recover quickly, the illness matters because dehydration can be a serious complication for vulnerable groups such as young children, elderly people, and those with existing health conditions.

诺如病毒（英语：Norovirus，NV），又稱為诺罗病毒、诺沃克病毒或膿融病毒，是一种引起非细菌性急性胃肠炎的病毒。諾羅病毒的特徵是感染人口密度較高和衛生環境差的地方，如郵輪。諾羅病毒主要由糞口途徑傳染，即食物被充滿病毒的糞便汙染所致，在人口密度高的地方也可能透過飛沫傳染。

Norovirus, also known as Norwalk virus, is the most common cause of gastroenteritis. The infection, sometimes referred to as the winter vomiting disease, is characterized by non-bloody diarrhea, vomiting, and stomach pain. Fever or headaches may also occur. Symptoms usually develop 24 hours after being exposed, and recovery typically occurs within one to three days. Complications are uncommon, but may include dehydration, especially in the young, the old, and those with other health problems.
The virus is usually spread by the fecal–oral route. This may be through contaminated food or water or person-to-person contact. It may also spread via contaminated surfaces or through air from the vomit of an infected person. Risk factors include unsanitary food preparation and sharing close quarters. Diagnosis is generally based on symptoms. Confirmatory testing is not usually available but may be performed by public health agencies during outbreaks.
