在加纳对人轮状病毒（HRV）感染及其季节性分布进行了为期12个月的研究。从阿克拉三个综合诊所的儿童中共获得561份粪便样本，447份腹泻粪便和114份非腹泻粪便（对照）。轮状病毒在12个月中的10个月被检测到，并显示出季节性趋势。在相对凉爽干燥的月份，气温较高，而在潮湿的季节，气温较低。感染高峰在2月（26.20/o）和9月（24.5%）。在447例腹泻粪便中的67例（15.00/o）和114例对照中的8例（7.0%）中检测到HRV。18个月以下年龄组的HRV分离率最高（20.2%）。RNA电泳分型以长型为主（83.6%）。非A组HRV检出率为14.9%。
Human rotavirus (HRV) infection and its seasonal distribution was studied over a 12-month period in Ghana. A total of 561 stool samples, 447 diarrhoea stools and 114 non-diarrhoea stools (controls), were obtained from children attending three polyclinics in Accra. Rotavirus was detected during 10 of the 12 months and showed a seasonal trend. It was high during the relatively cool dry months and low during the wet season. Peaks of infection were in February (26.20/o) and September (24.5%). HRV was detected in 67 of 447 of the diarrhoea stools (15.00/o) and in eight of 114 controls (7.0%). The HRV isolation rate was highest (20.2%) in the under-18-months age group. The RNA electropherotype of the HRV isolates was predominantly (83.6%) of the long type. Non-group A HRV was detected in 14.9% of the HRV-positive samples.
