TUBERCULOSIS; an airborne life taking disease
Tuberculosis is a contagious infection that usually attacks your lungs. Mycobacterium tuberculosis is a causative agent, it can also pass to brain and other parts of body from lungs. In most of the cases infection do not show any symptoms this is called latent tuberculosis. It is an airborne disease that can transfer from infected person to other through air while coughing, talking or sneezing.
STAGES OF TUBERCULOSIS
When we talk about TB, it is not always meant that you are sick. There are two forms of TB:
LATENT TB:
A person with strong TB has a latent TB stage. It means that you have germs of TB, but you have strong immune system that keeps the germs from spreading. These germs are not active. This stage of TB is not contagious. But in the future if your immune system becomes weak or you caught in such disease that weakens your immune system, it may activate your TB germs. Like if you caught in HIV or your chest infection is not normal or you had a infection in the past then doctor or medical care worker will give you medication to prevent from TB.
This type of TB does not have symptoms but certain type of test can claim your infection.
ACTIVE TB:
In stage type of TB, the germs are active and contagious. The germs multiply and you got sick. In ninety percent cases you get infection from latent stage of TB, like the germs in the latent stage of TB are activated and make you sick.
