Tuberculosis or consumption is one of the most dreaded diseases. It is a major health problem in India and often rated the number one killer. Over five lakh people die of this disease every year.

Tuberculosis is caused by a tiny germ called tubercle bacillus which is so small that it can be detected only by a microscope. The germ enters into the body through the nose, mouth and windpipe and settles down in the lungs. It multiplies by millions and produces small raised spots called tubercles.

Tuberculosis is not hereditary but an infectious or communicable disease. Those suffering from the disease for a considerable time eject living germs while coughing or spitting and when these enter the nose or mouth of healthy persons, they contract the disease. Mouth breathing and kissing as well as contaminated food and water are also responsible for spreading tuberculosis.
