Journal ArticleDOI
Monitoring and evaluation of programmes to prevent mother to child transmission of HIV in Africa.
TL;DR: Many countries are expanding the coverage of programmes to prevent mother to child transmission of HIV, but without true measures of effectiveness they may not be making the best use of resources.
