Print article The Matanuska-Susitna Borough, where schools have struggled with scattered closures due to coronavirus outbreaks, now has more daily average COVID-19 cases than any other part of the state. Even as Mat-Su took that position, several major high school sports events moved there from Anchorage due to less strict coronavirus protocols. Mat-Su moved into the top spot for daily average case rates Tuesday after the Yukon-Kuskokwim Delta region held that unwelcome position for four months as the virus ripped like wildfire through the hub of Bethel and outlying villages, some without running water. On Thursday, the Alaska Department of Health and Social Services reported about 35 cases per 100,000 in Mat-Su over the past 14 days and about 23 cases per 100,000 for the Yukon-Kuskokwim region.
