Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium Tuberculosis (MTB). TB is an air-borne infectious disease, which primarily affects the lungs.
Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that causes AIDS. HIV weakens a person’s immune system so it can’t fight the TB germs.
The World Health Organization (WHO) declared Tuberculosis (TB) a global emergency in 1993 and it remains one of the world’s major causes of illness and death. It is therefore important to raise public awareness about the devastating health, economic and social consequences of this disease.
There are two types of TB conditions: Latent TB infection and TB disease.
