Key summary

  • The program’s priority for TPT will be all children under 5 years old who are household contacts of people with bacteriologically confirmed pulmonary TB and all PLHIV.
  • TPT will also be expanded to other household contacts aged 5 years or more.
  • Symptom screening will be conducted for TB contacts under 5 years old and PLHIV, with TPT provided, based on the presence or absence of symptoms.
  • Other groups (contacts aged >5 years) will undergo additional tests (X-ray, bacteriological, and/or serological test) to rule out active TB, and only then can be initiated for TPT.
  • Serological tests (like TST, IGRA or TBST) to be done as available for detection of TB infection.
  • For non-PLHIV, the preferred TPT regimen will be a combination containing isoniazid and rifapentine (HP). However, children aged less than 2 years or less will still receive 3 months of HR, and HP will be provided to those aged 2 years and above. − If HP containing regimen is not available, then 3 HR will continue to be the choice of regimen.
  • For PLHIV, the preferred regimen is 3 HP. If the 3-month HP regimen is not available, a 6-month isoniazid (INH) regimen will be preferred choice for TPT.
