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.

Emerging Infectious Diseases
Infectious diseases are a continuing danger everyone. Some diseases have been effectively controlled with the help of modern technology. Yet new diseases—such as SARS and West Nile virus infection—are constantly appearing. Others, such as malaria, tuberculosis, and bacterial pneumonias, are now appearing in forms that are resistant to drug treatments. NCID offers a great deal of emerging infectious disease information.
