Possible reorganization of monobloc hospitals. Areas in blue are virus-free zones, areas in yellow are contaminated viral zones, and areas in green are uncertain viral status zones. All patients use the green road to the triage area. After screening, the patient is redirected according to the presumed viral state to the yellow or blue area. Dedicated elevators are identified and used by dedicated patients. The blue elevator cannot stop on the yellow floors, and the yellow elevator cannot go up to the blue floors. Green floors are shared common areas (technical units, radiology departments, etc.). If a second wave of infection hits the country, the COVID-negative floors will gradually be converted into COVID-positive floors. The yellow and blue arrows show the possible evolution in the case of a second wave.
