Tuberculosis epidemiology in the Asia–Pacific region

Abstract

Abstract: The Asia–Pacific region accounts for about 20% of the global burden of tuberculosis (TB). However, there are a wide variety of TB problems between countries and areas. This variety could be described in three dimensions: (i) historical trends of the TB epidemics, closely related to the advent of industrialization or urbanization; (ii) success in modern TB control in the early days; and (iii) expansion of the directly observed therapy, short course (DOTS) strategy during the past 20 years. Moreover, these dimensions have been subject to the ‘health infrastructure’ based on such social goods as people's education, economic standards, and social security or stability. The Asia–Pacific Region offers very good examples to illustrate the roles of these factors in leading to such a variety of TB problems as seen today. Thus, this region was the first to achieve the global target of DOTS by the end of 2005, that is to detect 70% of patients and to treat them with DOTS, and to successfully cure 85% of those detected.However, we should remember that we are currently challenged by TB combined with HIV infection and AIDS; TB with drug‐resistance, especially multidrug‐resistant (MDR) or extensively drug resistant (XDR) forms; TB in people with special risk factors, for example diabetes and senility; and other medical and socioeconomic problems. At the same time, we have to be careful about the premature loss of people's interest in TB, due to illusion or unfounded optimism, especially among medical professionals and the government.
