After a TB infection, some of the bacteria can become surrounded by immune cells and go dormant. This is how people still test positive for having TB bacteria without manifesting symptoms. It’s called a latent TB infection. If the immune system becomes weakened by other factors (autoimmune disease, fighting other infections, taking clot shots, etc) the TB bacteria can revive and cause another TB episode.
