Frequent HIV testing, and early start of antiretroviral treatment in those with HIV, would give short- and long-term declines in TB incidence

Implementing the 3Is policy (Intensified tuberculosis case finding, Infection control, and Isoniazid preventive therapy) combined with earlier start of ART can prevent HIV-associated TB. Early diagnosis and treatment, along with a comprehensive package of HIV care, form the basis of prevention and control of HIV-associated TB.
