Rubella seroprevalence and demographic feature analysis in pregnant women from Southern Pakistan.

: The present study was conducted to estimate the prevalence of rubella infection in pregnant women of district Lakki Marwat leading to foetal death, abortion, premature birth or congenital rubella syndrome. A total of 200 blood samples were collected from pregnant women visiting different maternal health care centers of the study area. Sera samples were tested for rubella-specific IgG and IgM antibodies through ELISA. The overall sero-positivity rate for IgG was 16% and for IgM was 2.5% in the pregnant women respectively. A higher sero-positivity rate was observed in the age group of 26-33 years. Women of rural areas showed higher sero-positivity rate than urban areas. The high sero-prevalence of rubella in the pregnant women of the study area poses a serious threat to the developing foetus.
