Using Virus Sequencing to Determine Source of SARS-CoV-2 Transmission for Healthcare Worker

Whether a healthcare worker's severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is community or hospital acquired affects prevention practices. We used virus sequencing to determine that infection of a healthcare worker who cared for 2 SARS-CoV-2-infected patients was probably community acquired. Appropriate personal protective equipment may have protected against hospital-acquired infection.
