Answers: how long can u live!!!
tuberculosis spreads in microscopic droplets that are released into the air when someone with the untreated, active form of the disease coughs, speaks, laughs, sings or sneezes.
Although tuberculosis is contagious, it's not especially easy to catch. In general, you need long-term contact with an infected person to become infected yourself. You're much more likely to contract tuberculosis from a family member or close co-worker than from a stranger on a bus or in a restaurant. A person with nonresistant active TB who's been effectively treated for at least two weeks is generally no longer contagious. Rarely, a pregnant woman with an active TB disease may pass the bacteria to her fetus.
Lowered immunity. When your immune system is healthy, macrophages can often successfully wall off TB bacteria, but your body can't mount an effective defense if your resistance is low. A number of factors can weaken your immune system. Having a disease that suppresses immunity, such as HIV/AIDS, diabetes or the lung disease silicosis, and receiving treatment with corticosteroids, arthritis medications or chemotherapy drugs can damage your body's ability to protect itself.
Close contact with someone with infectious TB. In general, you need to spend an extended period of time with someone with untreated, active TB to become infected yourself. You're most likely to catch the disease from a family member, roommate, friend or close co-worker.
Nationality. People from regions with high rates of TB
