Abstract

Tuberculosis (TB) remains a significant global health issue, with undiagnosed cases posing risks to public health and forensic personnel. Forensic autopsies are important in identifying TB cases, as undetected infections in deceased individuals can lead to occupational exposure through aerosolized transmission. However, TB surveillance in forensic autopsies remains insufficient, limiting its recognition in public health strategies. This study analyzed 43,190 forensic autopsies conducted in South Korea from 2019-2023, identifying 195 TB cases (0.45%), including 114 deaths (0.26%) primarily caused by TB. The highest prevalence was recorded in 2019 (0.59%), with a gradual decline in subsequent years. Regional analysis showed that Incheon had the highest TB prevalence (0.74%). Pulmonary TB was the most common (80.77%), followed by miliary TB (15.38%). These findings highlight the potential occupational risks for forensic personnel because of undiagnosed TB infections. Notably, 72.3% of TB cases were identified postmortem without previous medical records, increasing the likelihood of unprotected exposure. Additionally, forensic investigations often lack systematic reporting of TB cases, making it difficult to assess the true prevalence and risks. Strengthening TB monitoring in forensic autopsies can enhance case identification and improve public health surveillance. Establishing a more structured reporting system for TB cases in forensic settings may help prevent occupational exposure and support national TB control efforts.
