Students, faculty, staff and visitors, including those who are vaccinated, should wear masks while indoors on the Syracuse University campus starting Tuesday, a university official announced Monday on the Syracuse website.

"This includes in dining halls and fitness centers," Vice Chancellor for Strategic Initiatives and Innovation J. Michael Haynie said in the statement. "This is a temporary measure until transmission rates have declined sufficiently. We will continue to monitor pandemic conditions and modify or eliminate the indoor mask-wearing request as soon as appropriate."

The university noted that the Centers for Disease Control and Prevention (CDC) on Sunday identified Onondaga County as a region of "substantial" transmission due to an increase in confirmed COVID-19 cases.

It said mask-wearing was being introduced "out of an abundance of caution and to continue protecting the health and well-being of our entire campus community."

University operations will continue as usual.
