Rubella seroprevalence among unvaccinated school-aged children in Jos, North Central, Nigeria.

INTRODUCTION

rubella poses a significant public health threat, particularly in developing countries, where congenital rubella remains a preventable concern. This cross-sectional study examined rubella seroprevalence among children aged 10 and under from May to September 2016 in Jos, Nigeria.

METHODS

using a multistage sampling method, eligible participants who had not been vaccinated against the rubella virus and consented to participate in the study were recruited across schools in the city. Rubella-specific IgG and IgM antibodies were detected from eluted serum collected from the participants using the enzyme-linked immunosorbent assay (ELISA). Data analysis and visualization was done using the R software version 4.3.1.

RESULTS

of the 405 participants investigated in this study, 336 (82.96%) tested positive for rubella IgG, while 9 (2.22%) tested positive for rubella IgM. Factors such as age ≥ 5 years and lack of Western education showed significant associations with rubella seropositivity.

CONCLUSION

this study highlights the seroprevalence of rubella IgG and IgM antibodies among children aged 10 and under in Jos, Nigeria. The significant associations between rubella seropositivity and factors such as age ≥ 5 years and lack of Western education underscore the necessity for an effective rubella vaccination program to prevent congenital rubella syndrome (CRS).
