Norovirus, sometimes known as the winter vomiting bug[1] in the UK, is the most common cause of viral gastroenteritis in humans. It affects people of all ages.[2] The virus is transmitted by fecally contaminated food or water, by person-to-person contact,[3] and via aerosolization of the virus and subsequent contamination of surfaces.[4] The virus affects around 267 million people and causes over 200,000 deaths each year; these deaths are usually in less developed countries and in the very young, elderly and immunosuppressed.[5]
Norovirus infection is characterized by nausea, forceful vomiting, watery diarrhea, abdominal pain, and in some cases, loss of taste. General lethargy, weakness, muscle aches, headache, and low-grade fever may occur. The disease is usually self-limiting, and severe illness is rare. Although having norovirus can be unpleasant, it is not usually dangerous and most who contract it make a full recovery within a couple of days.[1] Norovirus is rapidly inactivated by either sufficient heating or by chlorine-based disinfectants, but the virus is less susceptible to alcohols and detergents.
