A member asked:
Could you tell me what are my chances of contracting tb after being exposed to someone with active tb?
A doctor has provided 1 answer
Moderate: Tb is considered moderately contagious. The chance of contracting TB depends on the closeness of the contact with the person who has pulmonary tuberculosis and the infectivity of that person. Persons with cavitary TB are most contagious followed by persons with positive sputum TB smears. Immunosuppressed persons are more susceptible to infection.
