Link Workers are the community resource persons, trained and deployed to encourage people to seek HIV counselling, testing and registration. They create awareness about HIV prevention and care at the village level.

The concept evolved in the Bagalkot learning site under the Samastha project in 2002. This later developed into the link workers scheme (LWS) that was led by the National AIDS Control Organisation (NACO) and funded by the Global Fund for HIV/AIDS, TB and Malaria (GFATM), implemented in more than 166 districts in India.

KHPT extended technical assistance and contributed towards development of operational guidelines for LWS.
