Background
Tuberculosis is responsible for almost 1.5 million deaths every year, with sub-Saharan Africa
accounting for around a third of them. Globally an estimated 4 million people with
tuberculosis go undiagnosed each year. Late diagnosis can lead to extensive lung damage,
with long-term consequences for peoples’ respiratory health, and onward transmission.
Project aim
To validate novel diagnostics for early diagnosis of tuberculosis
Study design
ERASE-TB is a multi-country prospective cohort study implemented in three Southern African countries (Mozambique, Tanzania and Zimbabwe). A total of 2108 household contacts of 903 people diagnosed with tuberculosis were enrolled in the study and followed every 6 months for a maximum of 24 months. At each visit participants are screened for TB, novel diagnostic tests are performed and samples are bio banked for future testing. Primary outcome will be microbiologically confirmed tuberculosis at baseline or during follow-up.
Duration
February 2021 to January 2025.
