Part D programs focus on the development and operation of systems of
primary health care and social services that benefit children, youth, and women living
with HIV and their families. These systems aim at building comprehensive,
community-based, coordinated programs that include health and social outreach elements,
as well as prevention. Title IV also works to develop new ways to effectively link
these care systems with HIV research supported by the National Institutes of Health
(NIH) and other organizations.
