目的研究探讨化学药物预防对农村地区中小学生结核菌感染者的预防效果。方法采取PPD皮内注射法,对随机抽取的部分农村中小学生进行结核菌感染状况调查,对强阳性的学生给予预防性服药,并与未服药组的强阳性学生进行对照。结果所调查学生阳性率42.1%,强阳性率12.8%,密切接触者强阳性率显著高于其它学生;服药组1年内未发生结核病例,而对照组1年内5人发病,发病率差异有统计学意义(P<0.05)。结论廊坊市农村地区中小学生结核菌感染率高,防治形势严峻;化学药物预防对学生结核病的发生有较好的预防作用,应予进一步推广应用。
Objective To study the preventive effect of chemical drugs on prevention of tuberculosis in primary and secondary school students in rural areas. Methods PPD intradermal injection was used to investigate the prevalence of Mycobacterium tuberculosis in selected rural primary and secondary school students. Preventive medication was given to strongly positive students and was compared with those of strong positive students who did not take medicine. Results The positive rate of the surveyed students was 42.1%, the strong positive rate was 12.8%. The strong positive rate of close contacts was significantly higher than that of other students. The tuberculosis cases did not occur within one year in the medication group, while the incidence of the five cases in the control group was statistically significant Significance (P <0.05). Conclusion The prevalence of TB in primary and secondary school students in rural areas in Langfang City is high, and the prevention and treatment situation is serious. Prevention of chemical drugs has a good preventive effect on the occurrence of tuberculosis in students, and should be further popularized and applied.
