With COVID cases and hospitalizations climbing, UMass Memorial is bringing back a mask mandate for staff when interacting with patients.

“We have continued to see a dramatic increase in the number of COVID-19 positive employees over the past two weeks, which has led to exposures of both fellow caregivers and patients,” a memo sent to staff on Thursday stated. “In response to this, as a protective measure for our staff and patients, effective immediately we are requiring mandatory caregiver masking for all patient encounters in all licensed clinical areas.”

The Worcester hospital says that if the trend continues, it may need to require masks for anyone who enters the building. They will re-evaluate the mandate in four weeks, “unless worsening conditions dictate otherwise.”
