Norovirus and sapovirus were detected in 12% of hospitalized infants with acute gastroenteritis in Chiang Mai, Thailand, revealing significant genetic diversity including a novel recombinant strain.
Supports noro-/sapovirus as regional gastroenteritis pathogens; leaves open recombinant strain significance and needs prospective validation.
Stool specimens from hospitalized infants with sporadic gastroenteritis in Chiang Mai, Thailand, between July 2000 and July 2001 were examined for norovirus and sapovirus by reverse transcription-PCR and sequence analysis. These viruses were identified in 13 of 105 (12%) specimens. One strain was found to be a recombinant norovirus.
