Implication

May support multi-virus testing in shellfish outbreaks; leaves open sapovirus contribution to clinical severity.

Structured PICO

P
Population
71 stool specimens (56 patients and 15 food handlers) from 11 oyster-associated outbreaks of gastroenteritis between January 2002 and March 2006 in Japan.
O
Outcome
Detection and genotyping of enteric viruses (norovirus, sapovirus, kobuvirus, astrovirus) in stool specimens.

Multiple enteric viruses, including multiple genotypes of norovirus and sapovirus, can co-contaminate oysters and cause gastroenteritis outbreaks, highlighting the need to screen for multiple viral agents.

Limitations

  • No oyster samples were available for screening to confirm the source of the viruses.
