Depends: Norovirus is the most common viral cause of "stomach flu" or gastroenteritis. Exposure can result in illness within 24 hours. Other causes of gastroenteritis like bacteria can take several days. Handwashing and food safety can help prevent spread of illnesses like these. Thanks for trusting HealthTap!
