Rubella Seropositivity and Associated Factors Among Young Female Adults in Bangladesh: A Cross-Sectional Study

A relatively high prevalence of rubella IgG seropositivity was detected. However, approximately one in ten participants remained susceptible to rubella infection during pregnancy and at risk of related adverse outcomes, including congenital rubella syndrome. Seropositivity was not associated with rubella vaccination history suggesting endemic transmission of the rubella virus. The low proportion of participants with a known vaccination history indicates gaps in vaccination documentation. Therefore, well-recorded vaccination histories and strengthened surveillance systems should be developed.
