Mar 4, 2011 (CIDRAP News) – A new report from the Centers for Disease Control and Prevention (CDC) makes clear why norovirus is the world's leading cause of gastroenteritis and the leading cause of foodborne disease outbreaks in the United States.

The virus is so contagious that one food handler with contaminated hands can infect hundreds of people, the report says. Those who have had the virus may have little protection against future infection.
