With a disproportionate burden of tuberculosis (TB) amongst migrants in Europe [1], Burman et al. [2] have highlighted the pressing need for alternative approaches to make TB infection (TBI) screening comprehensive and accessible. Across high-income Organisation for Economic Co-operation and development countries, a median of 52% of TB cases occur in foreign-born individuals, who are at their highest risk of developing TB disease within the first 5 years of migration [3]. Molecular epidemiological studies indicate that the majority of these cases occur as a result of TBI reactivation, often acquired overseas [4]. Within the UK, overseas-born migrants have a 14-fold higher TB incidence than UK-born individuals [5]. The World Health Organization therefore recommends that migrants from countries with a high TB burden may be prioritised for TBI screening [6, 7].

由于欧洲移民的结核病 （TB） 负担不成比例 [1]，Burman等人 [2] 强调了迫切需要替代方法来使结核病感染 （TBI） 筛查全面和可及。在高收入经济合作组织和发展国家中，中位数 52% 的结核病病例发生在外国出生的个体中，这些人在移民的前 5 年内患结核病的风险最高 [3]。分子流行病学研究表明，这些病例中的大多数是 TBI 再激活的结果，通常是在海外获得的 [4]。在英国，海外出生的移民的结核病发病率是英国出生者的 14 倍 [5]。因此，世界卫生组织建议可以优先对来自结核病高负担国家的移民进行 TBI 筛查 [6， 7]。
