Coronavirus Disease 2019 Outcomes in French Nursing Homes That Implemented Staff Confinement With Residents
French nursing homes in which staff voluntarily confined themselves to the facility (n=17 facilities corresponding to 794 staff and 1,250 residents) experienced COVID-19 cases in only 6% of facilities compared to 48% of facilities in which staff did not self-confine (n=9,513 facilities corresponding to 385,290 staff and 695,060 residents).
