Norovirus Behind Outbreak in Indiana

Noroviruses, which cause more than half of all foodborne illness outbreaks, are transmitted primarily through the fecal-oral route, and fewer than 100 norovirus particles are said to be needed to cause infection. Transmission occurs either person-to-person or through contamination of food or water. Foodborne norovirus transmission can occur when food is contaminated by an infected food handler.
