As one of the 22 high burden countries for tuberculosis (TB), China reported an estimated one million TB cases each year, accounting for more than one eighth of global cases. In 2010, the number of reported cases was 70 per 100,000 population.

The map shows the distribution of TB cases in China. As depicted by graduated colours, the number of reported cases per 100,000 population in 2010 was generally higher in rural central-western China than that in urban eastern China. The circle symbols, indicating retreatment patients, suggested that this could be high not just in high TB burden provinces but also municipalities with low incidence, as a result of rural-to-urban migration.

Tuberculosis in retreatment patients requires extensive chemotherapy and poses a threat to public health as drug resistance might have developed. Therefore, better case management and appropriate treatment regimens are important to control tuberculosis in China.

Data for the map were obtained from Chinese Center for Disease Control and Prevention.

中國是全球22個結核病高負擔國家之一,每年新增約一百萬個病例,佔全球超過八份之一的病例數目。2010年,中國每十萬人口中便有70個新增病例。

地圖顯示中國結核病的分佈情況。依圖中顏色所示,2010年中國中西部的農村地區每十萬人計的結核病病例數目較東部的城鎮地區為高。圖中圓圈符號則顯示,高比例的復發患者除了出現於結核病高負擔的省份外,亦因城鄉遷移而出現於發病率低的直轄市。

相比一般結核病,復發患者需要較長時間的療程。由於可能已產生抗藥性,高復發現象對公共衛生構成更嚴重的威脅。要有效控制中國結核病疫情,妥善個案管理及適當的治療處方均為重要。
