Masking is optional in all locations except some health care facilities (including the Student Health Center, Rochester Regional Health Family Clinic, and the NTID Audiology Center). Individuals are encouraged to assess their own personal risk when deciding how and when to mask in optional locations.
There are two primary factors to consider in a mask. The first is the layers of protection in the mask. N95, KN95, KF94 offer the most protection. Surgical masks are also quite good. Many layers of cloth are better than a single layer.
The second factor to consider in a mask is the fit. It should snuggly cover your nose and mouth so that there is little air entering or exiting from the edges of the mask. With a good fit, glasses should not fog.
