Nevada on Saturday reported a record daily increase of additional confirmed COVID-19 cases. But health officials later said the bulge largely resulted from data entry errors that delayed the posting of hundreds of cases from two previous days. The state Department of Health and Human Services reported an additional confirmed 1,099 cases, mostly from metro Las Vegas. The number of additional cases was more than double the previous record of 507 reported Thursday. But the Southern Nevada Health Agency said the reported increase included over 600 cases that should have been reported earlier in the week. The additional reported cases raised the state’s total to 16,339 with 500 deaths, including two newly reported on Saturday.
