Molecular identification of rotavirus strains associated with diarrhea among children in Kwara State, Nigeria
The study was carried out to determine the molecular characteristics of the rotavirus strains associated with diarrhea among children in Kwara state, Nigeria. A total of 150 stool samples were collected from diarrheic children. The stool samples were screened for rotavirus,using Enzyme linked Immunosorbent assay (ELISA). Nine (9) stool samples were positive 6%. The prevalence of rotavirus infection according to sex was as follows: Male 3.30% and Female 2.70%. The distribution of infection according to age of the children was as follows; <1-2 years 4% and 3-5 years had 2%. The prevalence of infection in dry months was 4.7% while in wet months it was
