Washington University Danforth Campus (including North, West, South and Tyson Campuses) COVID-19 Policy effective from July 30, 2021 until further notice

The main purpose of the mask is to prevent the wearer from expelling small virus-containing droplets of saliva or mucus into the air and infecting others. Wearing a mask reduces the likelihood that an infected individual could spread the virus to people around them (colleagues, co-workers, faculty, staff, students, family, friends, etc.). This is especially important to reduce the spread from infected people who may be asymptomatic. It also provides some protection for the wearer. Therefore, to reduce the spread of the virus and to protect the health of all our faculty, staff, students, and other community members, Washington University is requiring masking indoors for all individuals, regardless of vaccination status. 

All WashU personnel and visitors are required to wear a mask while on campus as follows: 

  • This policy applies faculty, staff, students, trainees, contractors, vendors, and other visitors. 
  • When wearing a mask, it should fit snugly over the wearer’s mouth and nose. 
  • Masks are required at indoor gatherings for everyone, regardless of vaccination status or the size of a meeting or gathering.
  • Masks are not required when an individual is inside a private office or room or while eating or drinking, allowing for personal space as much as possible.
  • Masks are required in open office settings such as cubicles.
  • Masks are encouraged but not required for outdoor activities, particularly at large events or in crowded settings.
  • Gaiters, bandanas and any masks with valves are not adequate and should not be worn.
