A 23-year-old woman who had worked as a hostess at a nightclub was found dead in her house. The cause of death was diagnosed as miliary tuberculosis from the findings of medico-legal autopsy. Recently, tuberculosis (TB) has re-emerged as a health problem due to recurrence in the aged, and infections among health care workers and young adults like the present case. Currently, the common source of TB transmission is recurrence in the aged, but global migration, difficulty to achieve permanent immunity by BCG vaccination, immunodeficiency such as HIV infection, and drug abuse and/or sexual intercourse are also thought to be associated with tuberculosis in young adults. Forensic pathologists should be aware of such connections with TB, and should take care not to become mediators of TB infections.
