Report by the Center for Disease Control and Prevention (US) on the consequences of the introduction of COVID-19 into a long-term residential care facility in Washington, which resulted in cases among 81 residents, 34 staff members, and 14 visitors; 23 persons died.
The report highlights limitations in effective infection control and prevention. Staff working in multiple facilities was identified as one of the factors that contributed to intra- and interfacility spread.
The report suggests the following measures:
- Identifying and excluding potentially infected staff members
- Restricting visitors except in compassionate situations
- Ensuring early recognition of potentially infected residents
- Implementation of appropriate infection control measures
