Abstract:To determine the prevalence and characterization of lassa virus (LASV) in western area of Sierra Leone. Eight hundred and twenty samples were collected from western area of Sierra Leone by random sampling method and the lassa virus specific IgG antibody were detected.The seropositivity rate in the sampled population was 28.78%, and the 95% confidence interval (95% CI) was 25.68%-31.88%. Anti-LASV seropositivity rate was 43.48% (80/184) in rural area, which was higher than 24.82% (136/548) in urban area. The difference was statistically significant (χ2=23.06, P<0.05).There was no significant difference in anti-LASV seropositivity rate between male and female, neither among different age groups. LASV IgG seroprevalence in western area of Sierra Leone was still very high and there was significant difference between rural and urban. The sanitary conditions and the rodent control should be improve especially in rural.
