The tuberculosis situation in 46 countries in Asia is reported. TB is still prevalent in Asia and more than 5 million or 60% of new TB patients in the world occur in Asia annually. Prevalence of TB is high in rural and urban areas, the young and the aged, female as well as males. Because of high prevalence of TB and delay in case-finding, annual risk of TB infection is still 1.5% or more in almost all countries. The cure rate by standard chemotherapy is often less than 50%, so that the prevalence of initial drug resistance is very high in many countries. As a result, TB is not decreasing to a satisfactory degree in almost all the developing countries of Asia. To improve this situation, WHO Headquarters presented a new TB controlstrategy recently. Priority is given to curing 85% of detected smear positive cases in all the developing countries by the introduction of short-course chemotherapy including rifampicin, and to detecting 65% of existing smear positive cases. The author stresses the importance of improvement and activation of the TB control program in Asian countries for TB control in the world.
