Effective immediately masks are optional, but encouraged, in all Medical School spaces except in the clinical wings on floors 2-7 of the Medical School building, the clinical research center and in iCELS. When in the clinical wings, clinical research center, iCELS or, of course, any UMass Memorial site, masks are required, consistent with the UMass Memorial Medical Center guidelines. The South Street campus is also mask optional. As before, we ask that you respect the decision of any colleague who continues to wear a mask while at work. Learn more here.
