Authorities in North Carolina are reporting 350 new coronavirus cases in the past 24 hours, pushing the total number of cases to 6,500. Numbers released Sunday by the state health department show laboratory-confirmed cases increased from 6,140 cases to 6,493. The death toll increased from 164 to 172. Modeling released Friday by the University of Washington suggests that North Carolina may have reached its peak in coronavirus cases in the last few days, and that social distancing could be relaxed as soon as May 11 if sufficient testing is conducted, large gatherings are limited and other provisions remain in effect. Other models are less optimistic.
