Previously, considerable advances have been made in the effort to prevent mother-to-child HIV transmission (PMTCT) through various treatment policies in Kenya. These policy changes have been propagated by scientific discoveries that have been rapidly translated into health policy. The main objective of this study is to assess the changing HIV treatment policy to PMTCT services in Kenya. We assess the coverage of PMTCT programme in Kenya from 2002 to 2016 and estimate the risk of transmission of HIV in light of changing policy on PMTCT prophylaxis. We systematically compared performance of options A, B, B+ and Antiretroviral Therapy (ART) in terms of their effects in preventing new infant infections. Results show a good level of enrollment but low global coverage rate over the years. In Kenya, full HAART represents a favorable policy option from a cost-effectiveness perspective to prevent future infant infections, save mothers' lives and reduce orphanhood. These findings provide a starting point for the development of interventions responsive to policy changes in PMTCT programs.
