Aim 3: Evaluate for indirect effects of the SPIRIT intervention on the prescribing of IPT to child (≤14 years of age) household contacts of active TB cases, and HIV-infected children (12 months to 14 years of age). The investigators hypothesize that IPT prescribing for child (≤14 years of age) household contacts of adults with active TB disease and for HIV-infected children (12 months to 14 years) will increase in SPIRIT intervention compared to control groups, as an indirect effect on DHO support for IPT implementation, IPT prescribing practices and patient perceptions of IPT.
