The Basic Services Division provides HIV Counseling and testing services for HIV infection, the critical first step in detecting and linking people with HIV to access treatment cascade and care. It also provides an important opportunity to reinforce HIV prevention. TSACS is offering these services since 1998 with the goal to identify as many people living with HIV, as early as possible (after acquiring the HIV infection), and linking them appropriately and in a timely manner to prevention, care and treatment services.
