Leaving no one behind: lessons from implementation of policies for universal HIV treatment to universal health coverage.

ART coverage has increased at global, regional and national levels to all population groups. However, the gains have not been equitable among locations and populations. Policies towards universality may widen the inequity in resource-limited settings unless countries take precautions and "put the last first". We argue that primary health care and public health approaches, with multi-sectoral actions and community engagement, are vital to minimize inequity, achieve UHC and leave no one behind.
