Our work develops procedures and useful tools for the screening, assessment and management of prevalent infectious or parasitic diseases (tuberculosis, measles, chickenpox, scabies, bed bugs) among asylum seekers and detainees in the canton of Vaud, populations living in similar closed settings. Its aim is to support health professionals in their work, to maintain the health of the target population and to protect the health of the community. Through a literature review and a focus group with experts, it is proposed to harmonize the existing procedures in asylum seekers centres end prisons of the canton of Vaud. The proposed decision algorithms are coherent with the recommendations of the literature and relevant in terms of public health and ethics, as well as feasible logistically and acceptable by the field health professionals.
