What they found
This study found that latent tuberculosis infection (LTBI) prevalence was 11.8% in Liaocheng and 9.7% in Weihai. Increased PM2.5 and NO2 concentrations were associated with higher odds of LTBI in both cities.
What they studied
Researchers conducted a cross-sectional study in Liaocheng and Weihai, China, from April 13-30, 2025, to assess the link between air pollution and LTBI prevalence in the elderly.
Takeaways
The study suggests that managing air pollution is crucial for preventing and controlling tuberculosis.
