Abstract

Abstract : Background . Under Option B plus, the transmission of Human Immunodeficiency Virus (HIV) along the Early Infant Diagnosis (EID) of HIV cascade remains unknown. We described HIV transmission along the EID cascade and determined associated factors at Arua Regional Referral Hospital, Northwestern Uganda. Methods . Data on 295 mother-baby pairs in EID care (January 2014 and April 2015) was extracted, cleaned, and analysed in STATA. Univariate, bivariate, and multivariate analyses were performed. Independently associated factors were stated in adjusted odds ratio (AOR), 95% confidence interval (CI), andp -values. Results . 233 (89.0%) mothers were above 30 years, 251 (85.1%) were in World Health Organization (WHO) clinical stages I/II at enrolment, 170 (57.6%) attended antenatal care (ANC) visits during recent pregnancy, and 204 (69.1%) delivered in a health facility. Meanwhile, 257 (87.1%) HIV Exposed Infants (HEIs) received Nevirapine prophylaxis from birth up to 6 weeks and 245 (83.0%) were exclusively breastfed during the first 6 months. Of 295 mother-baby pairs, 25 (8.5%) HEIs turned HIV-positive along the EID cascade. Baseline maternal CD4 count of more than 500 cells/ul compared to less than 500 cells/ul (adjusted odds ratio (AOR) = 0.29; 95% Confidence Interval (CI): 0.10–0.85;p = 0.024) and exclusive breastfeeding (EBF) in the first 6 months of delivery in contrast to not EBF in the first 6 months (AOR = 0.17; 95% CI: 0.52–0.55;p = 0.003) reduced HIV transmission. Meanwhile, ANC visits, place of delivery, time of Nevirapine initiation, and maternal antiretroviral therapy use were not significantly associated with infant HIV transmission. Conclusion . HIV transmission was high. High baseline CD4 count and exclusive breastfeeding reduced HIV transmission.
