Is it safe to use a microphone in a classroom shared by other instructors?

According to the Centers for Disease Control and Prevention, transmission from surfaces contaminated with the virus that causes COVID-19 is not a substantial source of infection. The virus is primarily spread through exposure to respiratory fluids containing the virus, typically through inhalation of small droplets and aerosols; contact between exhaled droplets/particles and mucous membranes (mouth, nose, eyes); or by directly touching contaminated hands or objects to mucous membranes.

Because instructors using microphones in classroom settings will be required to wear masks, direct contact between the surface and the mucous membranes of users should not occur. Campus public health experts recommend practicing ample hand hygiene (wash and sanitize hands) before and after using shared equipment as a way to further reduce the limited potential for spread. Users may also gently clean the microphone with a disinfectant wipe. Please work with your building manager on sourcing disinfecting supplies.
