Norwalk Agent / Norwalk-Like Viruses

Norwalk virus is classified as a member of the calicivirus  group of enteric viruses.  With humans as the only known reservoir, it is transmitted primarily by the fecal oral route. Outbreaks suggest contaminated food, water and raw shellfish to be the primary route of transmission with transmission to family members secondary.

BioVir has isolated Norwalk from water sources by filter concentration, cell culture for subsequent identification by molecular techniques (ie. Polymerase Chain Reaction (PCR)).
