Contact Investigation

Every case of TB started as a contact to a person with active pulmonary or laryngeal TB disease. For this reason, it is essential to identify, examine, evaluate, and treat all persons who are at risk of infection with Mycobacterium tuberculosis (m. tb) due to recent exposure to a newly diagnosed or suspected case of pulmonary or laryngeal TB.

The documents linked below describe and outline the procedural steps in a contact investigation.
