Nebraska officials are asking dozens of people who attended the Special Olympics basketball tournament last week in Fremont to self-quarantine. A news release Saturday from the Nebraska Department of Health and Human Services says the woman diagnosed with COVID-19 spent most of Feb. 29 at the Fremont Family YMCA, where the tournament was held. Health officials are asking the tournament's players, coaches and team staff members to self-quarantine and monitor themselves for symptoms of the virus until March 14. They're also asked to self-report to the Nebraska public health online system or call their local health departments for next steps. The YMCA reopened yesterday after a deep cleaning, but nearly 40-percent of the facility's programming has been put on hold until a 14-day waiting period for signs of the coronavirus to appear has ended.
