Microfilarial infection in eight districts of Nepal
Abstract
An epidemiological study for lymphatic filariasis was conducted in 8 districts of Nepal representing three geographical regions i.e. terai, mid-terai and hilly region. The overall microfilariaemia, antigenaemia and lymphatic filariasis rate were found to be 0.63%, 4.70% and 10.75% respectively. The highest crude disease and endemicity rate were found in Bhaktapur district (23.88% and 28.36% respectively), and the least. in Saptari and Rautahat districts (7.69% and 1.47% respectively). Regarding age-wise prevalence, the endemicity rate of filariasis gradually increasesd with the increase in age. According to sexwise prevalence, the infection rates in both sexes were almost similar. Regarding region-wise prevaJence the highest endemicity rate was found in Hilly region (24.05%) and the least in Terai region (12.54%). The sensitivity of ICT card test was found 7.5 times higher than smear test. The survey study showed that illiteracy has direct impact regarding the knowledge of filariasis. For this, awareness programs through different media can help in controlling this disease.
