Norwalk virus. Coloured transmission electron micrograph (TEM) of a section through Norwalk viruses, originally isolated from an outbreak in Norwalk, Connecticut, USA in 1968. Characteristic of Norwalk viruses is their ill- defined 'hairy' surface. The virus is associated with diarrhoea and vomiting outbreaks among humans. The Norwalk virus is believed to be similar to the caliciviruses, which are also implicated in gastroenteritis and have been found in the faeces of children with diarrhoea. Magnification unknown.
