Tigray survey finds 10.6% with presumptive TB after the war
A community study of 2,340 residents, run after the conflict that wrecked the region's health system, found presumptive tuberculosis above 10% in both town and countryside.
| Group | Value (%) |
|---|---|
| Overall | 10.6 (8.4 to 13) |
| Rural | 12.3 (10.8 to 14) |
| Urban | 11.8 (10.6 to 13.1) |
A community survey conducted in Tigray after the region's war found that 10.6% of residents had presumptive tuberculosis — symptoms suggestive of active disease — with a 95% confidence interval of 8.4% to 13% [s1]. The study, published in the Journal of Clinical Tuberculosis and Other Mycobacterial Diseases, reads the figure as a marker of what the conflict did to a health system that once detected and treated TB, rather than as a confirmed case count [s1].
The context is the destruction. Tigray recorded 6,700 confirmed tuberculosis cases in 2020, the year before the war began [s1]. Ethiopia as a whole is a high-burden country, ranking third in Africa and eighth globally for TB, and war, the authors note, is an ideal condition for the disease to spread [s1].
What was measured
The study was a community-based comparative cross-sectional survey of 2,340 participants, carried out from January to February 2024 using multistage cluster sampling across rural and urban areas [s1]. "Presumptive tuberculosis" is a screening category, not a diagnosis: it covers anyone with at least one suggestive sign — a cough lasting more than two weeks, fever, loss of appetite, night sweats, chest pain or weight loss [s1].
That distinction matters for reading the headline number. A presumptive-TB prevalence of roughly one in ten does not mean one in ten residents has active tuberculosis; it means that share carried symptoms warranting a diagnostic work-up that, in a functioning system, most would clear. In a region whose laboratories and clinics were damaged, the gap between who needs testing and who can get it is the finding.
Town and countryside alike
The burden was distributed more evenly than the usual rural disadvantage would predict. Presumptive TB prevalence was 12.3% in rural areas (95% CI 10.8% to 14%) and 11.8% in urban areas (95% CI 10.6% to 13.1%) — a slight difference, with overlapping confidence intervals [s1].
The factors associated with presumptive TB point at living conditions and a thinned-out primary-care network: inadequate ventilation, going to sleep hungry, close contact with a known TB patient, and households that had not been visited by health extension workers [s1]. The last of these is the clearest fingerprint of system collapse — the community health workers who would normally find and refer cases were not reaching homes.
The limits, stated plainly
This is a single region, surveyed once. A cross-sectional design captures a moment, not a trend, and cannot establish that the war caused the burden it measured, only that the burden is high in its aftermath [s1]. Because the outcome is symptom-based, the 10.6% figure is best read as the size of the group needing diagnostic follow-up, which will exceed the number with confirmed disease [s1]. The authors frame the result as a tool for targeting screening — identifying where active cases are most likely to be found — rather than as a prevalence of tuberculosis itself [s1].
Why it matters beyond Tigray
Globally, the direction of travel had been the other way. WHO's Global Tuberculosis Report 2025 found that TB killed more than 1.2 million people and made an estimated 10.7 million ill in 2024, both lower than the year before, and that the WHO African Region cut TB incidence by 28% and deaths by 46% between 2015 and 2024 [s2]. A post-conflict resurgence in one region runs against that regional gain, and illustrates how quickly a disruption can reverse it [s1][s2].
What to watch
The near-term question is whether diagnostic and treatment services can be rebuilt fast enough to convert screening into care. The study's practical recommendation is to bring TB screening and diagnosis closer to communities during the post-war recovery, so that the people flagged as presumptive can actually be tested and, where needed, treated [s1].
