Tuberculosis is a Fatal Disease among Some Developing Countries of the World

Tuberculosis (TB) is an infectious fatal disease mainly among the developing countries. It is caused by a bacterium called Mycobacterium tuberculosis and spreads through the air and infects the lungs and other organs and parts of the persons who come in contact to the infected persons. It remains a major global health problem and about 2 billion people are thought to be infected with TB and about 1.3 million died each year from the disease. In the 95% of all cases, 99% of death occurs in developing countries, with the greatest burden in Sub-Saharan Africa and Southeast Asia. India alone accounts for an estimated one-quarter (26%) of all TB cases worldwide and only China and India combine accounting for 38%. To prevent TB, the WHO recommends that infants receive a BCG vaccine where TB is a common disease. At present each year globally about 100 million children receive BCG vaccine. Drug resistant TB is a rising global problem which is more difficult and expensive to treat and cure or sometimes it is impossible to treat successfully. It can occur when healthcare providers prescribe the wrong treatment, the wrong dose, or wrong length of time for taking the drugs or irregular and incomplete medicines are used by the patients
