When and for how long is a person able to spread tuberculosis?
A person with TB disease may remain contagious until he/she has been on appropriate treatment for several weeks. It is important to note that a person with TB infection, but not the disease, cannot spread the infection to others since there are no TB bacteria in the sputum.
