Data are presented as median (interquartile range), unless otherwise indicated; data from Germany, Italy, Norway and Spain, as well as coverage data from Switzerland, represent two studies and so are presented as median (range). Follow-up screening studies were excluded as they were only reported in studies from Belgium and the Netherlands. RC: reception/holding centre; POA: port of arrival; OS: occasional screening; CPA: community post-arrival screening. #: Belgium has been carrying out centralised screening upon arrival since 1999; prior to that screening was not systematic, but voluntary screening at reception centres occurred; ¶: screening of refugee groups of specific origin offered asylum in the country (Vietnamese for Denmark and Kosovan for Ireland) at or shortly after arrival; these studies were also considered occasional screening studies since they covered only a specific group of migrants; +: CPA covers migrants and RC asylum seekers; §: among asylum seekers in RCs; the coverage estimate for migrant entry screening is 70% (C. Erkens, KNCV Tuberculosis Foundation, The Hague, the Netherlands; personal communication); ƒ: there was one additional record of (occasional) screening of Kosovan refugees upon arrival in Norway (n = 600), with a tuberculosis yield of 0.70% and coverage of 74.0%.
