Twenty-eight newborns delivered in Chiang Mai, Thailand in October and December, 1988 were followed up for rotavirus infection for two years after birth. Sixty-eight percent (19/28) of the index children discharged group A human rotavirus (HRV) antigen and/or viral genomic RNA in their feces during the two years, and 7.1% (2/28) discharged twice during the period. Seasonal distribution of HRV-positive fecal specimens was 29% (6/21) in January to April, 1989, 9.5% (2/21) in August and September, 1989, 57% (12/21) in December, 1989 to April, 1990, and 4.8% (1/21) in June, 1990.
Eighty-six per cent (24/28) of the index children developed diarrhoeal symptom and the total number of the episodes was 67, i.e., 2.39 for one child during the two years. One severe episode, 20% (3/15) of moderate and 12% (6/51) of mild diarrhoeal episodes were correlated to the rotavirus infection.
