The purpose of this trial is to determine whether isoniazid (INH) reduces the risk of Mycobacterium tuberculosis (MTB) infection in HIV-exposed but uninfected (HEU) children, as well as to determine epidemiologic and immunologic correlates of MTB infection in HEU.
Randomized controlled trial (RCT) of isoniazid (INH) vs. no INH to prevent Mycobacterium tuberculosis infection in HIV-exposed uninfected (HEU) infants.
