RESUMO
Rotavírus foram pesquisados em 607amostrasfecais de crianças de até 6 anos de idade com quadros de diarréia aguda, no período de maio de 1986 a abril de 1990. Foi utilizada a técnica de eletroforese em gel depoliacrilamida (PAGE), sendo os rotavírus detectados em 123 amostras (20,27%) das quais 107(87,00%) apresentaram perfil eletroforético longo, compatível com o subgrupo II. Os rotavírus não foram encontrados no grupo controle constituído de crianças sadias, sendo porém detectados em 7,80% das crianças internadas por outras causas que não diarréia aguda. A maioria das crianças positivas para rotavírus encontrava-se na faixa etária de 6a24 meses (73,98%). A média depositividade nos meses chuvosos (outubro a abril) foi igual a 9,60% e no período seco, 34,48% com picos que variaram entre 53,17 e 73,27% nos meses de junho e julho, os mais frios do ano.

ABSTRACT
Rotavirus testing was perfimed on fecal samples of 607 infants and young children aging from Oio 6 years with acute diarrhoea between May 1986and April 1990. Samples were analyzed by polyacrylamide gel electrophoresis (PAGE). Rotaviruses ware detected in 123 samples (20.27%);from those, 107 $S7.00%) were classified as subgroup U (long profile). Rotaviruses were not detected in the control group of healthy children, but it were present in 7.80% of the children hospitalizedfor other causes but acute diarrhoea. Most of the children with rotavirus infection rangedfrom 6 to 24 months of age (73.98%). The mean of positive cases during the rainny months (October to April) was of 9.60% and during the dry period was of34.48%. The highest values were 53.17 and 73.27% in June and July, the coldest months of the year.
Keywords: Rotavirus. Acute diarrhoea in infants. Epidemiology.
