Prevalence and risk factors of latent tuberculosis infection in healthcare workers in Eastern China

The LTBI prevalence among HCWs in Yantai is relatively low. TB screening should be included in the annual health check-ups for HCWs, especially for high-risk groups such as frontline HCWs, long-serving workers, and those with household contact with TB, to reduce the risk of TB infection. These findings highlight the need to enhance infection control measures and active surveillance for at-risk HCWs, even in low TB incidence settings. Future research should focus on longitudinal studies to understand LTBI dynamics and the effectiveness of interventions in low-incidence settings.
