Human rotavirus infection was studied over a 13-month period (January 2004 to January 2005) in children <5 years of age admitted with severe diarrhea at the Korle-Bu Teaching Hospital in Accra, Ghana. During this period, 206 hospitalizations for diarrhea were recorded, with 34.0% (70/206) being positive for rotavirus infection. Infection occurred throughout the year, with peak rotavirus infection occurring during the month of March. Hospitalization associated with rotaviruses was most common in the 6-8 month age group. The case fatality rate of rotavirus infection was 2.9% (2/70) and occurred in children <12 months of age. Four rotavirus VP7 genotypes (G1, G2, G3, and G9) were detected. The predominant genotypes were G2 (22.9%), G1 (17.1%), G9 (17.1%) and G3 (12.9%). Mixed G types were also detected. The predominant VP4 genotypes (P types) were P[6] (38.6%), P[8] (21.4%), P[4] (4.3%) and P[9] (1.4%). The predominant rotavirus strains infecting children in Accra were G9P[6] (10.0%) and G1P[8] (8.6%). Strains with unusual genotypes such as G2P[8] and G(2/3)P[6] were also detected.
