Assessment of the effectiveness of PMTCT (Prevention of Mother to Child Transmission) to Children Born from HIV-1 positive Mothers
Abstract: Mother-to child transmission (MTCT) of HIV is one of the biggest challenges of the HIV/AIDS pandemic especially in resource constrained settings. Africa has the highest burden of the disease accounting for about 90% of pediatric HIV infections. Approximately 370,000 children became infected with HIV globally; most of these infections occurred through mother-to-child transmission. PMTCT (prevention of mother to child transmission) service reduces the risk of this transmission. In the absence …
