Norovirus spread by restaurant employees
The CDC's Morbidity and Mortality Weekly Report (MMWR) includes a report titled, "Norovirus Outbreak Associated with Ill Food-Service Workers --- Michigan, January--February 2006" this week. In it, we learn that:
On January 30, 2006, the Barry-Eaton District Health Department (BEDHD) in Michigan was notified of gastrointestinal illness in several members of two dining parties after a meal at an Eaton County restaurant on January 28.
- BEDHD began an investigation to identify the source and agent of infection
- Norovirus genogroup I (GI) was detected in stool specimens submitted by multiple patrons and employees.
- Several food-service workers had been ill during January 19--February 3, 2006, and that a line cook had vomited in the restaurant on January 28, possibly increasing environmental contamination and transmission of virus.
- At least 364 restaurant patrons became ill with norovirus during the outbreak.
