Seroprevalence of rubellaSerological analysis found that 2.1% of the study partici-pants were positive for antirubella IgM, indicating a recent rubella virus infection (or reinfection). The seroposi-tivity rate of antirubella IgG was 86.3%, which indicates past exposure/infection with development of protective immunity. Thus, the rate of susceptibility to rubella among the pregnant women was calculated to be 13.7%. Overall, 1.9% of participants were found to be positive for both IgM and IgG. The positivity rates for antirubella IgM were 5.4% in the age range 15–19years, 2.5% among those who had a secondary level education, 2.4% among merchants and 2.2% among urban residents or married. The rate of antirubella IgG peaked in the age range 20–24years (89%), and decreased thereafter with increasing age. The seropositivity of IgG was higher among urban residents (90%), merchants (90.5%), women with a primary level
