Implication

May warrant Aichi virus testing in adult oyster-related outbreaks; leaves open prospective studies before diagnostic adoption.

Structured PICO

P
Population
47 stool samples from adult patients in oyster-associated gastroenteritis outbreaks and 397 pediatric stool samples in Aichi Prefecture, Japan, plus an unspecified number of individuals aged 7 months to 35 years for antibody testing.
I
Intervention
Enzyme-linked immunosorbent assay (ELISA) for Aichi strain antigen and neutralizing antibody
O
Outcome
Prevalence of Aichi strain antigen in stool samples and neutralizing antibody in the population

The Aichi strain is a newly identified small round virus that likely causes diarrhea primarily in young adults, with antibody prevalence increasing significantly with age.
