[An analysis of the uneven prevalence of tuberculosis in various areas and regions in China].

This article analyzed the uneven prevalence of tuberculosis in various areas and regions and its trend in China nowadays based on the data of the nationwide epidemiological sampling survey of tuberculosis in 1979 and 1990. The highest prevalence was 25-30 times higher than the lowest among provinces, municipalities and regions. The prevalence in remote areas and regions was significantly higher than that in coastal areas and municipalities. The ratios of the prevalence of pulmonary tuberculosis between cities and countryside were 1:2.4-2.8. Most of the investigation points which had a higher prevalence was located in remote and inland areas. Some minority areas which had higher prevalence resided in the northwest and southwest remote areas. The uneven tuberculosis prevalence in various areas and regions indicated that tuberculosis is still an important public health problem in China at present.
