क्या हैं जो टीबी बीमारी का पता लगाना कठिन बनाता हैं?
Many infectious diseases cause illness very quickly. With TB, a person can be infected with the bacteria, but not become sick with TB disease. This is called latent TB infection. A person with latent TB is not contagious and cannot pass TB on to others. The other type of TB is active TB disease. Active TB may take several decades to occur—or it may develop soon after infection. Someone with active TB is contagious and can spread the disease to others. The active form may progress more quickly in people who have a weak immune system. Other infectious diseases have a latent period. These diseases can be hard to diagnose.
