Abstract
Previous studies have found declining incidence of tuberculosis (TB) in Bissau, Guinea-Bissau. This study aimed to report incidence rates of TB for the period 2004-2020, stratifying by sex, smear-status, and HIV-status, as well as describe developments in TB case fatality rate and diagnostic delay. Data from the Bandim Health Project HDSS and the TB registry from Jan 1st, 2004 to Dec 31st, 2020 were used. Incidence rates were calculated for each year and for smear-positive, smear-negative, HIV-positive, HIV-negative, and unknown HIV-status. Incidence rate ratio and test for trend were done using a one-step Newton approximation to the log-linear Poisson regression coefficient. Overall TB incidence declined only slightly over the period from 294 per 100,000 in 2004 to 273 in 2020. TB/HIV coinfection declined from 108 in 2004 to 14 in 2020, as did incidence among females and smear-negative cases. Incidence of PTB in Bissau, Guinea-Bissau is declining slowly, if at all. TB incidence among females, smear-negative TB, TB case fatality rate, and TB/HIV coinfection and diagnostic delay are declining.
