CDC says norovirus sickens up to 21 million a year

From Lisa Schnirring at CIDRAP, excerpt :

" Getting a handle on the nation's norovirus burden is difficult, because reporting isn't required and there's not a widely used test for the disease, but experts from the US Centers for Disease Control and Prevention (CDC) who analyzed the latest data reported new estimates yesterday—up to 21 million infections each year, as many as 800 fatal.

The new estimates provide some detailed and surprising numbers. For example, the CDC experts predict that the disease strikes five times during a typical American's lifespan.

Before yesterday's new numbers, reported in Emerging Infectious Diseases, the most often cited norovirus burden numbers were from a 1999 report that covered a broad array of foodborne illnesses. While the new annual illness estimate is slightly lower than the earlier one, the CDC researchers reported overall upticks in hospitalization and death numbers."
