This open comparative study for evaluating hypersensitivity to tuberculin among medical students (n=441), nursing students (n=178) and economics students (n=230) in Vitória, State of Espírito Santo, had the aim of assessing whether the prevalence of positive tuberculin tests among healthcare students could be used as a sentinel event for nosocomial transmission in localities with high endemicity. There was a significant change in the frequency of purified protein derivative reactivity in the nursing students (20.3%) and medical students (18.4%), in comparison with the economics students (6%) (p <0.001). As expected, the medical and nursing students had more knowledge about tuberculosis than did the economics students (p <0.001). Our data suggest that the incidence of Mycobacterium tuberculosis infection among nursing and medical students in our region, which has high endemicity of tuberculosis, does not differ from what is found in low-incidence countries. These data reinforce the need for implementing biosafety programs for this target population.
这项开放性比较研究旨在评估圣埃斯皮里图州维多利亚市的医学生（n = 441）、护理专业学生（n = 178）和经济学专业学生（n = 230）对结核菌素的超敏反应，目的是评估在高流行地区，医护专业学生结核菌素试验阳性的患病率是否可作为医院内传播的哨兵事件。与经济学专业学生（6%）相比，护理专业学生（20.3%）和医学生（18.4%）的纯化蛋白衍生物反应频率有显著变化（p < 0.001）。正如预期的那样，医学生和护理专业学生比经济学专业学生对结核病有更多的了解（p < 0.001）。我们的数据表明，在结核病高流行的我们地区，护理专业学生和医学生中结核分枝杆菌感染的发生率与低发病率国家的情况没有差异。这些数据强化了为这一目标人群实施生物安全计划的必要性。
