( Norovirus)
Norovirus (was "Norwalk-like viruses")[1], an RNA virus of the Caliciviridae taxonomic family, causes approximately 90% of epidemic non-bacterial outbreaks of gastroenteritis around the world,[2][3] and is responsible for 50% of all foodborne outbreaks of gastroenteritis in the US.[4] Norovirus affects people of all ages. The viruses are transmitted by faecally contaminated food or water and by person-to-person contact.[5] After infection, immunity to norovirus is usually incomplete and temporary.[6] There is an inherited predisposition to infection and people whose blood type can be detected in their saliva are more often infected.[2] Outbreaks of norovirus disease often occur in closed or semi-closed communities, such as long-term care facilities, hospitals, prisons, dormitories, and cruise ships where once the virus has been introduced, the infection spreads very rapidly by either person-to-person transmission or through contaminated food.[7] Many norovirus outbreaks have been traced to food that was handled by one infected person.[8] Norovirus is rapidly denatured by chlorine-based disinfectants, but because the virus particle does not have a lipid envelope, it is less susceptible to alcohols and detergents.[9]
