I don't have the numbers off the top of my head, but I would think that well over 50% of people who are screened need some kind of diagnostic procedure or medical intervention, including treatment, so quite a high proportion of people. One of the diseases you referred to is tuberculosis.
Je ne peux pas vous citer des chiffres de mémoire, mais je dirais que plus de 50 p. 100 des demandeurs d'asile examinés ont besoin d'un diagnostic ou d'une intervention, y compris un traitement médical.
