Rotavirus infection in Nigerian infants and young children with gastroenteritis.

In a study conducted over a 5-month period (September 1979 to January 1980), rotaviruses were detected by counterimmunoelectrophoresis in the feces of 16 (13.8%) of 116 infants and young children between 1 and 48 months old with acute, sporadic gastroenteritis, at Ife, Nigeria. The highest frequency of rotavirus infection was found in th 7- to 12-month age-group (18.9%). Males constituted 61% of the sample and excreted rotavirus at a significantly higher rate than did females (P less than 0.01). Rotavirus infection was higher in the drier months of November-January (19.3%) than during the rainy months of September and October (8.5%).
