目的掌握武安市中小学入学新生结核病免疫现状,为做好学生结核病防治工作提供依据。方法对武安市4所城区小学、5所乡村小学、3所乡村中学初一学生,2所城区中学初一学生共8 664名进行结核菌素(PPD)试验。结果武安市乡村小学一年级新生PPD阳性率为60.45%,城区一年级新生PPD阳性率为63.02%,差异有统计学意义(P<0.05);乡村小学一年级新生PPD强阳性率为2.23%,城区小学一年级新生PPD强阳性率为1.03%,差异有统计学意义(P<0.01)。城区初一新生PPD阳性率为56.77%,乡村初一新生PPD阳性率为50.44%,差异有统计学意义(P<0.01)。结论武安市城区小学一年级新生阳性率较高,说明学生对结核菌有一定抵抗力。但乡村学校新生PPD强阳性率较高,学校传染病防治工作存在隐患,需要进一步重视在校学生的结核病防治工作。
Objective To grasp the status quo of TB immunization among primary and secondary school students in Wu’an and provide the basis for the prevention and treatment of tuberculosis among students. Methods A total of 8 664 first grade students from 4 urban primary schools, 5 rural primary schools, 3 rural middle schools and 2 junior high schools in Wu’an City were tested for tuberculin (PPD). Results The positive rate of PPD was 60.45% in primary freshmen of Wuan’an primary school and 63.02% of freshmen in urban primary school, with a significant difference (P <0.05). The positive rate of PPD in primary freshmen in rural primary school was 2.23% The positive rate of PPD in grade one freshmen in urban primary school was 1.03%, the difference was statistically significant (P <0.01). The positive rate of PPD in urban freshmen was 56.77%, and the positive rate of PPD in rural freshmen was 50.44%, the difference was statistically significant (P <0.01). Conclusions The first-grade freshmen in Wu’an urban primary school have a high positive rate, indicating that the students have some resistance to TB. However, there is a strong positive rate of PPD among freshmen in rural schools. There is a hidden danger in the prevention and treatment of infectious diseases in schools. Further attention should be paid to tuberculosis prevention and control among school-going students.
