Abstract

The epidemiological trends of tuberculosis since the pre-chemotherapy era to the recent resurgence in developed countries and further worsening of the problem in developing countries are presented in this review article. The declining trend of magnitude of tuberculosis observed in most of the developed countries since the beginning of this century as a natural phenomenon hastened after the introduction of chemotherapy. However, no such downward trend was observed in most of the developing countries including India even after the introduction of chemotherapy. In recent years, the declining trend of tuberculosis in developed countries has witnessed a reversal as a result of HIV epidemic, socio-demographic factors and emergence of multi-drug resistance. These factors have also led to further wo rsening of the problem in developing countries. In fact, the global incidence of tuberculosis is expected to increase further in the coming years, more significantly in the countries of Africa and South-East Asia including India. This calls for more intens ive and sustained efforts at decreasing the reservoir of infection and reducing transmission.
