IU will no longer require masks in classrooms, residence halls, dining spaces, common areas or at athletics venues starting March 4, the university said in a news release it. Masks will still be worn in health care and research spaces. The university cited a decline in COVID-19 cases at the university and throughout the state. March 4 marks “the anticipated expiration of state and county public health orders,” it said. Whether or not people continue to mask on campus will be personal decisions, said Dr. Aaron Carroll, IU’s chief health officer. The university said it will continue to distribute KN95 and N95 masks.
