Risk Factors Associated with Loss to Follow-Up during Tuberculosis Treatment in the Sanatorium Hospital of Luanda, Angola.

Background: Tuberculosis (TB) continues to be a serious public health threat that affects the most vulnerable populations. Patients who are lost to follow-up (LTFU) after TB diagnosis still represent one of the biggest challenges to TB control.

Method: In this prospective observational study, we aimed to identify and analyse the risk factors associated with LTFU among TB patients who started first-line TB treatment in the Sanatorium Hospital in Luanda.
