What happens after exposure to TB?
After getting exposed to the TB bacteria, a couple of scenarios can happen. Some people may develop active TB soon (within weeks). In others, the bacteria lays dormant. This is the latent phase of infection. There’s a 5-10% chance of developing an active infection without treatment. The highest chance for developing the infection is within the first 1-2 years after getting the bacteria. This chance decreases if you take treatment for Latent Tuberculosis Infection.
