Des Moines Performing Arts has announced that beginning Sept. 25 all guests attending a performance inside a DMPA venue must wear a mask at all times. According to a news release, guests also must show proof of full COVID-19 vaccination or the results of a negative COVID-19 test. The only exception to the mask requirement is when guests are enjoying refreshments in a designated area, the release stated. The requirements will remain in place for the foreseeable future. In addition to the new policies, DMPA has updated several elements of its infrastructure to address COVID-19 concerns, including updating its HVAC systems with MERV 13 filters, adjusting for increased fresh air circulation and adding portable air filtration systems in key areas of the facility. There are also additional hand sanitizing stations, protective guards around concession  areas and the implementation of touchless transaction options. Jonathan Brendemuehl, director of communications, said the health and safety of audiences, artists and staff will always be a top priority at Des Moines Performing Arts. “Over the past 18 months our colleagues have been working with health experts and industry leaders to guide our policies,” he said in the release. “These policies are our best efforts to ensure a safe and healthy environment for everyone.”
