HomeSince the introduction of data collection on TB-diabetes mellitus (DM) co-morbidity into the surveillance of active TB disease in 2005, underreporting of DM status gradually decreased until 2012; since then, it has remained approximately constant (Figure 10). The overall proportion of missing information on DM has consistently been above 50%, which makes it challenging to interpret national-level data on TB-DM co-morbidity. In the last 2 years, the proportion of individuals diagnosed with active TB disease for whom DM information was missing has increased, following a period of stability: from 50.3% in 2018 to 61.9% and 56.4% in 2019 and 2020, respectively (Figure 10).
The percentage of individuals reported with active TB disease identified as having a DM diagnosis did not change significantly over time, remaining in the range of 21.4-26.5% (Figure 11).
