The highest prevalence observed in the second trimester may have been because most of the pregnant women presented in the antenatal clinic in their fourth and fifth months of pregnancy. The virus is so much in constant circulation that prevalence did not differ much with the reproductive characteristics and sociodemographic data studied. and eight (40%) were positive for rubella IgG and IgM antibodies, respectively. None of them of the possible risk factors analyzed were significantly associated with illness. Age and additional sociodemographic factors were of little significance, and awareness of rubella was low. Summary The prevalence of rubella was high in both pregnant (93.1%) and nonpregnant ladies (90%), suggesting sustained transmission, which further suggests endemicity. The presence of rubella IgM and IgG antibodies in pregnant women predisposes babies to congenital rubella syndrome and emphasizes the need for the initiation of a national rubella vaccination system in Nigeria. =3, =3, em P /em =0.343), trimester of pregnancy (IgM- em /em 2=0.220, em df /em =2, em P /em =0.896, and IgG- em /em 2=2.745, em df /em =2, em P /em =0.253), reproductive characteristics studied, sociodemographic data gathered, and clinical characteristics observed were not significant risk factors for rubella computer virus illness for pregnant or nonpregnant ladies (where applicable), while shown in Furniture 1C4 and ?and6.6.

Conversation About 93.1% of the pregnant women experienced IgG antibodies to rubella virus. This value is similar A-889425 to the 97.9% prevalence reported by Mohammed et al10 in Zaria, 96.1% prevalence reported by Tamer et al18 in the western region of Turkey, and 88.6% prevalence reported by Fokunang et al19 in Cameroon. The high prevalence acquired may have been due to a sustained illness and the development of antibodies to rubella computer virus. This suggests that rubella computer virus is common in the study area and that the majority of the pregnant women experienced previously been exposed to the computer virus. The number acquired with this study is definitely, however, much higher than the 53%, PPP2R1B 7%, 68.5%, 54.1%, and 76% reported in other A-889425 parts of Nigeria by Onakewhor and Chiwuzie,11 Agbede et al,12 Bamgboye et al,13 Bukbuk et al,14 and Onyenekwe et al15 in Benin City, Ilorin, Ibadan, Maiduguri, and Lagos, respectively. This indicates the distribution of rubella computer virus across Nigeria varies for reasons that could possibly be climatic. The development of IgG antibody is an effort made by the immune system to help neutralize the computer virus. This antibody prolongs existence and confers immunity against reinfection. Consequently, it is right to presume that the pregnant women that experienced IgG antibodies are immune. A clearer picture was, however, seen when the seroprevalence of IgM antibody to rubella computer virus was also regarded as. A prevalence of 38.8% was obtained among the pregnant women for IgM antibody. Significantly, 36.9% of these pregnant women also experienced IgG antibody, suggesting either reinfection or resolving primary infection and that they were not actually immune as concluded earlier, but were still in the recovery stage, although this was not confirmed with an avidity test. Most of these ladies were in their second and third trimesters of pregnancy, suggesting that they were infected earlier in pregnancy, as virtually all infected persons should have developed IgG antibodies by 30 days postinfection.20 These pregnant womens fetuses should therefore not be excluded from the risk of CRS. The A-889425 38.8% prevalence acquired is much higher than any that has been reported in Nigeria. Ogbonnaya et al,16 Onakewhor and Chiwuzie,11 Pennap et al,17 and Agbede et al12 reported prevalences of 6.8%, 10%, 4.2%, and 1.1% in Abia State,.
