  • Masks are optional on the COD main campus and centers. In limited situations, masks will continue to be required in certain instructional settings, such as labs. Faculty will communicate to affected students directly.

Wearing a facemask that covers the mouth and nose can help reduce the transmission of the virus responsible for COVID-19 and its variants. A significant number of individuals with COVID- 19 lack symptoms and those who eventually develop symptoms can transmit the virus to others before showing symptoms. Droplets and aerosols that are projected when speaking, coughing, sneezing, etc., can contain the COVID-19 virus, and remain suspended in the environment for hours. Therefore, the virus can spread between people interacting in close proximity. Face coverings can reduce both the emission of virus when worn by an infectious person and reduce the uptake of virus when worn by a person in proximity to an infectious person.¹

Guidelines for Selecting a Face Mask1

DO Choose Masks That:

  • Have two or more layers of washable, breathable fabric
  • Completely cover your nose and mouth
  • Fit snugly against the sides of your face and don’t have gaps
  • Have a nose wire to prevent air from leaking out of the top of the mask

DO NOT Choose Masks That:

  • Are made of fabric that makes it hard to breathe, for example, vinyl
  • Have exhalation valves or vents which allow virus particles to escape

Special Considerations:

  • Scarves, ski masks and balaclavas are not substitutes for masks
  • Face shields can be work in addition to masks, but cannot be substituted for masks or worn alone
