Medical students are considered to be personnel with a high level of risk for developing latent tuberculosis infection (LTBI). One possible reason is lack of knowledge about the transmission, prevention, and biosafety standards for tuberculosis disease.
This research aimed to determine the rate of LTBI among medical students studying in a private School of Medicine in Monterrey, Mexico.
In this cross-sectional study, we obtained blood samples from 174 medical students. LTBI was diagnosed using the QuantiFERON®-TB Gold Plus test. The prevalence of LTBI was compared with the socio-demographic data of the students and their level of knowledge and use of personal protective equipment (PPE).
The proportion of LTBI in the students was 20.6%. Medical students in their first few years of medical school had a lower prevalence of LTBI than students in their final years of medical school. Additionally, students with a low level of knowledge on LTBI and low use of proper PPE had a higher prevalence of LTBI.
In a School of Medicine in Monterrey, Mexico, the proportion of medical students with LTBI was low but the proportion increased in advanced students. Students who demonstrated adequate knowledge and use of respiratory protective masks had lower prevalence rates for LTBI.
医学生被认为是发生潜伏性结核感染（LTBI）风险较高的人群。一个可能的原因是对结核病的传播、预防和生物安全标准缺乏了解。
本研究旨在确定在墨西哥蒙特雷一所私立医学院学习的医学生中LTBI的发生率。
在这项横断面研究中，我们采集了174名医学生的血样。使用QuantiFERON®-TB Gold Plus检测诊断LTBI。将LTBI的患病率与学生的社会人口统计学数据及其对个人防护装备（PPE）的知识水平和使用情况进行比较。
学生中LTBI的比例为20.6%。医学院低年级的医学生LTBI患病率低于高年级学生。此外，对LTBI知识水平低且正确使用PPE较少的学生LTBI患病率较高。
在墨西哥蒙特雷的一所医学院，LTBI医学生的比例较低，但高年级学生的比例有所增加。对呼吸防护口罩有充分了解并使用的学生LTBI患病率较低。
