Norovirus (formerly Norwalk agent ) is an RNA virus ( taxonomic family Caliciviridae ) that causes approximately 90% of epidemic nonbacterial outbreaks of gastroenteritis around the world, and may be responsible for 50% of all foodborne outbreaks of gastroenteritis in the United States . Norovirus affects people of all ages. The viruses are transmitted by fecally contaminated food or water, by person-to-person contact, and via aerosolization of the virus and subsequent contamination of surfaces. After infection , immunity to norovirus is usually incomplete and temporary. There is an inherited predisposition to infection, and individuals with blood type AB are more often infected, while blood types O and AB can confer partial protection against symptomatic infection. --> Outbreaks of norovirus infection often occur in closed or semiclosed communities, such as long-term care facilities, overnight camps, hospitals, prisons, dormitories, and cruise ships, where the infection spreads very rapidly either by person-to-person transmission or through contaminated food. Many norovirus outbreaks have been traced to food that was handled by one infected person. Norovirus is rapidly inactivated by either sufficient heating or by chlorine-based disinfectants , but the virus is less susceptible to alcohols and detergents , as it does not have a lipid envelope .
