To implement well functioning and efficient PMTCT programs that provide quality services and are accessible and affordable, programs need to be well thought out and be based on informed decision-making. That is, program planners should refer to the most current national and sub-national guidelines on PMTCT and guidelines for all related services that may be offered, such as family planning and reproductive health services. This section of the toolkit includes resources that will provide program planners with guides and tools for PMTCT program planning and implementation.
