Tuberculosis (TB) is the most common presenting illness and cause of death among people with HIV.
It is fatal if undetected or untreated and is the leading cause of death among people with HIV, responsible for more than 1 of 3 HIV-associated deaths.
The sexual partners and drug injecting partners of people diagnosed with HIV infection have an increased probability of also being HIV-positive.
WHO recommends assisted HIV partner notification services as a simple and effective way to reach these partners, many of whom are undiagnosed and unaware of their HIV exposure and may welcome support and an opportunity to test for HIV.
Early detection of TB and prompt linkage to TB treatment and ART can prevent these deaths.
TB screening should be offered routinely at HIV care services and routine HIV testing should be offered to all patients with presumptive and diagnosed TB.
The Human Immunodeficiency Virus (HIV) targets the immune system and weakens people's defense systems against infections and some types of cancer.
As the virus destroys and impairs the function of immune cells, infected individuals gradually become immunodeficient.
Serological tests, such as RDTs or enzyme immunoassays (EIAs), detect the presence or absence of antibodies to HIV-1/2 and/or HIV p24 antigen.
No single HIV test can provide an HIV-positive diagnosis.
