Epidemiological survival pattern, risk factors, and estimated time to develop tuberculosis after test and treat strategies declared for children living with human immune deficiency virus.

Background: Due to their age category and the immune-suppressing effects of HIV, children were more vulnerable to experience endogenous reactivation of latent bacilli in the lung and increased risk of active tuberculosis incidence. The aim of this study is to assess the survival pattern, risk factors, and estimated time to develop TB after children started ART at selected health facilities of North Wollo, Ethiopia, from November 1, to September 30, 2021.

Methods: Facility-based retrospective cohort study was employed from November 1 to September 30, 2021.
