Can non contagious tb become contagious
co worker has it and I'm worried
A person who does not get sick is known to have non-contagious latent TB. This TB is dormant and cannot be transmitted. Further on, even if tuberculosis is contagious, it's not that easy to catch.
It has the potential, but it's pretty rare. If you're worried, go get checked out by a doctor. :)
there is a difference between non-active tb, and being a carrier. if a person has non-active tb,too much stress and physical depletion of strength can turn the tuberculosis into active tb.
