abstract
The present study was conducted to find out the prevalence of rubella virus infection among pregnant women of IDPs (internal displaced persons) of NWA agency in Baka Khil camp KPK, Pakistan from February 2015 to July 2015.Two hundred fifty (250) blood samples were randomly collected from IDPs pregnant women. Sera were separated and screening was with Enzyme linked immunosurbant assay (ELISA). At overall 19.6% (49/250) and 3.6% (9/50) were positive against rubella specific IgG and IgM antibodies respectively. A higher prevalence was found in women of 32-39 years age group. 3rd trimester and house wife showed a high positivity rate (IgG=22.10%, IgM=5.26%) and (IgG=22.14%, IgM=5%) respectively. Also illiterate and women of low income status were at high risk of infection. The high prevalence of rubella infection during pregnancy can lead fetus at high risk of congenital rubella syndrome (CRS). So it is advisable to health planners to avoid further incidence of rubella infection by the immunization of childbearing age women.
