Abstract

Rotavirus testing was performed on fecal samples of 607 infants and young children aging from 0 to 6 years with acute diarrhoea between May 1986 and April 1990. Samples were analyzed by polyacrylamide gel electrophoresis (PAGE). Rotaviruses were detected in 123 samples (20.27%); from those, 107 (87.00%) were classified as subgroup II (long profile). Rotaviruses were not detected in the control group of healthy children, but it were present in 7.80% of the children hospitalized for other causes but acute diarrhoea. Most of the children with rotavirus infection ranged from 6 to 24 months of age (73.98%). The mean of positive cases during the rainy months (October to April) was of 9.60% and during the dry period was of 34.48%. The highest values were 53.17 and 73.27% in June and July, the coldest months of the year.

摘要

1986年5月至1990年4月期间，对607名0至6岁患急性腹泻的婴幼儿粪便样本进行了轮状病毒检测。样本通过聚丙烯酰胺凝胶电泳（PAGE）进行分析。在123份样本中检测到轮状病毒（20.27%）；其中，107份（87.00%）被归类为II型亚组（长型）。在健康儿童对照组中未检测到轮状病毒，但在因其他原因而非急性腹泻住院的儿童中，轮状病毒的检出率为7.80%。大多数感染轮状病毒的儿童年龄在6至24个月之间（73.98%）。雨季（10月至4月）阳性病例的平均检出率为9.60%，旱季为34.48%。在一年中最冷的6月和7月，检出率最高，分别为53.17%和73.27%。
