COVISAN was set up from April 14, 2020 at 4 pilot sites of Assistance publique-Hôpitaux de Paris (APHP) to break the sequence of transmission of SARSCoV-2 according to an original model already proven in Haiti to eradicate cholera in the 2010s. This device relies on a systematic screening of the possible COVID-19 cases, assistance in their containment and care for their close relatives. Mobile teams carried out home visits to evaluate the possibilities of home confinement, to propose material help (errands, laundry, outsourcing accommodation) and to propose a screening of their relatives. By June 17, 2020, 6376 patients have been moved towards COVISAN, and 153 had a positive RT-PCR to SARS-CoV-2. COVISAN has made possible an innovating town-hospital partnership, involving multiple actors (nursing staff, administrative staff, logistician, and service professions). Health authorities have decided to model their strategy to control the SARSCoV-2 spread closely to COVISAN's, and implemented “contact tracing”. COVISAN that learned by doing, has also encountered some difficulties, mainly concerning the different staff statutes and also with the internal and external communication.
