I just found out a person with tuberculosis was in contact with me at work. how risky was that interaction? should i get tested?

Yes: You should get tested and evaluated by your doctor. If your initial skin test is negative you'll need repeat testing in 8-10 weeks.

Yes: If your colleague has active pulmonary tuberculosis, the health department will do the testing. If he/she has latent tb, you are not at risk and need not be tested. The risk of catching TB depends on factors related to how close a contact you had, for how long, and how advanced the case was when exposed. It is transmitted by airborne droplets.

Screen: The transmission is by airborne droplets. The office workers should all be tested if there is a case of active TB in the office.
