ABSTRACT
Rotavirus infection is very common in developing countries and occurs at least once in children under the age of 5 years. The rate of detection of rotavirus infection in various age groups (0-5 years) in patients with gastroenteritis admitted to hospital from the Faisalabad region, Pakistan is reported. Out of 300 fecal samples, 189 (57.3%) were positive for rotavirus by immunoassay. Patients aged 7-12 months (35.4%) were infected most commonly followed by the age group 0-6 months (28%). Different genotypes of rotavirus were identified by hemi-nested RT-PCR. The most common genotype was G1P[8] (25.3%), followed by G1P[6] (21.1%). Other genotypes were G1P[9], G2P[6], G9P[10]), G3P[8] (1.5%), and G9P[11] (1%). There were two (1%) cases of mixed G genotype, one patient with two genotypes G1, G10 and another patient with 3 genotypes G1, G10, and G12. There were 6 (3.1%) cases of mixed P genotypes, 3 P[4], P[11] and 3 P[8], P[11]. These results provide an outline of rotavirus infection in this area for the first time.
