What is the incubation period of tuberculosis?

Answer 1

To answer the question, once the bacteria begin to multiply, it generally takes 2 to 12 weeks to either develop symptoms of TB or to show a positive PPD skin test. A latent infection can stay dormant in your lungs for years or decades, with no sign but a positive skin test, or it could convert to an active infection at any point. However, once it becomes known that you have a TB infection, active or inactive, it can be treated and eradicated with antibiotics. If successfully treated, the bacteria are not going to stay in you for the rest of your life; they will die. Since the skin test looks for the immune reaction to the bacteria, not the bacteria itself, the skin test will remain positive throughout your lifetime, even if the infection is completely cured.
