Evaluation of the latent tuberculosis screening and treatment strategy for asylum seekers in Stockholm, Sweden 2015-2018 - a record linkage study of the care cascade.

In many countries with low tuberculosis (TB) incidence (<10/100,000) a high proportion of cases originate from latent TB infection (LTBI) reactivation among migrants from high-incidence countries (≥100/100,000) who have been infected before arrival in the host country [1, 2]. Consequently, LTBI screening and management for migrants is an important intervention to reduce TB incidence in those countries [1, 3, 4].
