Trends and delays in pulmonary tuberculosis diagnosis among elderly patients (≥ 60 Years) in Southern China: a 13-year surveillance data analysis (2010–2022)

The burden and delays associated with TB diagnosis remain significant among the elderly in Southern China. Enhanced health education and proactive screening efforts are crucial for this high-risk group to mitigate diagnostic delays, particularly for those with respiratory comorbidities and in less developed regions. Future research should focus on addressing these barriers and evaluating the effectiveness of tailored interventions to improve TB control strategies for the elderly.
