The following is a letter from MSUB's COVID-19 Incident Command Team & Chancellor Hicswa: Dear Campus Community, Last Friday, Commissioner of Higher Education Clay Christian sent a memo to all MUS campuses formally sunsetting the Healthy MUS Planning Guidelines, effective immediately. This action is taken in partnership with the Montana Board of Regents and is based on federal, state, and local public health guidance and on the recommendation of the Healthy MUS Task Force. The Commissioner's memo also covers issues related to quarantine & isolation housing; international travel; event hosting and vaccines. View the full memo here.  Mask requirement: There is no longer an MUS system-level mask mandate, which includes MSU Billings. RiverStone Healthâs CEO and Health Officer John Felton, with whom we maintain a close relationship, concurs with these guidelines as there is no longer a mask mandate for Yellowstone County or Montana. The CDC has released updated health and safety guidelines and face mask guidelines for vaccinated individuals which can be found here.
