Connectivity between long-term care homes and subsequent SARS-CoV-2 outbreaks

Staff cohorting was associated with reduced importation risk of SARS-CoV-2 cases into LTCH.

Implementing these structural strategies to meet the LTCH workers and residents' needs are pivotal to prevent and manage future respiratory virus outbreaks.
