Surveillance of rotavirus gastro-enteritis in children in Blantyre, Malawi
2013
AbstractBackground: Rotavirus is a leading cause of acute gastro-enteritis in infants and young children worldwide. Previous studies of rotavirus gastro-enteritis in Malawi have documented a high disease burden with an extensive diversity of circulating rotavirus strains.Methods: In anticipation of the introduction of national rotavirus vaccination, a 2-year surveillance study was undertaken in 2008 and 2009 of children in Blantyre seeking hospital care for acute gastro-enteritis. Rotavirus was detected in faecal specimens by ELISA. Rotavirus G and P types were determined by RT-PCR.Results: Rotavirus, which circulated throughout the year, was detected in 220/720 (31%) children. Over 85% of patients with rotavirus gastro-enteritis were <1 year of age. A total of 13 rotavirus G/P types were identified, the most common strains being G1P[8] (39·5%), G12P[6] (23·2%), G2P[4] (9·5%), G9P[8] (6·8%) and G8P[4] (6·4%).Conclusions: The data confirm the importance of rotavirus infection in young Malawian children and...
