Noroviruses (genus Norovirus, family Caliciviridae) are a group of related, single-stranded RNA, non-enveloped viruses that cause acute gastroenteritis in humans. The most common symptoms of acute gastroenteritis are diarrhea, vomiting, and stomach pain. Norovirus is the official genus name for the group of viruses previously described as ?Norwalk-like viruses? (NLV).
Noroviruses spread from person to person, through contaminated food or water, and by touching contaminated surfaces. Norovirus is recognized as the leading cause of foodborne-disease outbreaks in the United States. Outbreaks can happen to people of all ages and in a variety of settings.

Norovirus Information
This new toolkit is a complementary resource to the Guideline for the Prevention and Control of Norovirus Gastroenteritis Outbreaks in Healthcare Settings that was released in 2011.
Healthcare professionals can use the materials in the toolkit to educate staff and patients about norovirus and to assist with outbreak response.
