本文调查了我国部分地区非典型分枝杆菌感染率:海南(71.1％)、福建(47.8％)、河南(33.7％)、四川(29.5％)、内蒙(45％)、山东(40.9％)、河北(28.7％)、陕西(16.9％)、山西(34.3％)、辽宁(57.1％)。流行特点:东南沿海气候温暖的海南、福建两省PPD-B阳性率高于气候寒冷的北方诸省。男高于女,农村高于城镇。各组PPD-B阳性率皆高于对照的PPD-RT23。调查同时采用了随机抽样、典型和新兵三种方法。
This article investigated the prevalence of atypical mycobacteria in some areas in China: Hainan (71.1%), Fujian (47.8%), Henan (33.7%), Sichuan (29.5%), Inner Mongolia (45%), Shandong Hebei (28.7%), Shaanxi (16.9%), Shanxi (34.3%) and Liaoning (57.1%). Epidemic characteristics: Hainan and Fujian provinces with a mild climate along the southeast coast have a higher positive rate of PPD-B than those provinces in northern China with cold climate. Male is higher than female, rural is higher than town. The positive rate of PPD-B in each group was higher than that of the control PPD-RT23. The survey also used random sampling, typical and recruits three methods.
