There are two types of tuberculosis − Latent TB infection (non-infectious) and tuberculosis (infectious).
Latent tuberculosis infection:
– People infected with latent TB do not have symptoms and may not feel sick.
– A skin or blood test will indicate whether a person has a bacterial infection.
– It is not possible to transmit TB germs from an infected person to other people.
– People with latent TB infection may never develop the disease because the bacteria lie dormant. In other cases, especially when people with weakened immune systems are involved, the bacteria can become active and cause TB.
– Treatment is needed to ensure that infected people do not develop active TB disease, but preventive treatment may not be an option in some cases.
– About 5-10% of people with latent TB infection will develop the disease if left untreated.

– Treatment usually involves taking a combination of medicines for six months.
– People with weakened immune systems, such as those with HIV Or diabetes, more susceptible to tuberculosis.
TB is spread through the air when a person with active TB infection coughs, sneezes, talks or sings. Bacteria can remain in the air for hours.
