BACKGROUND: Cameroon has adopted the option B+ for the prevention of mother-to-child transmission (MTCT) program of HIV in August 2014 in order to eradicate MTCT of HIV.
OBJECTIVE: To analyze in routine life settings, efficacy of option B+ for PMTCT and associate factors.
METHODS: We conducted a cross-sectional study over a 6-month period in the ESSOS hospital center. Study population comprised HIV-positive mothers and their infants aged 0-24 months. Variables included were : moment of HIV maternal testing, timing of commencement of maternal antiretroviral therapy (ART) and self-reported adherence to ART. Efficacy was measured through early and late MTCT rate and associated factors.
RESULTS: We included 200 mothers and 124 infants. Under option B+, the rate of transmission was at 4.20% at 6 weeks and 5.83% at 12 months. The rate of HIV transmission in breastfed infants stood at 3.7%. In unadjusted analysis, bottle-feeding, term at birth, early screening and management during pregnancy were associated with lower risk of HIV transmission. After adjustment, term at delivery after 37 weeks adjusted odds ratio (AOR) [0.059; (0.0061; 0.56)] was protective; while lack of prophylaxis was among HIV-exposed infants emerged as the main factor associated with residual transmission of HIV [AOR 117.23 ; (3.55 ; 3874.9)].
CONCLUSION: In this setting of Yaoundé, routine option B+ posted laudable results at 12 months even amongst breastfed children and should therefore be made sustainable.
