The epidemiological impact of HIV infection comprises :

1. Increased risk of infection
2. Increased risk of breakdown into disease among TB infected
3. Increased fatality among the diseased.

This is simply due to the fact that the lowered resistance brought about by this virus makes people who are dually infected i.e., infected with both HIV and tubercle bacillus ,very susceotible to develop tuberculosis.The overall risk of dually infected persons who were first infected with infected with tuberculosis and later infected with HIV,probably reaches 50 per cent((Grzybowsky-Ind J Tub 1995,42,195-200
