Nevada health officials reported 843 more confirmed cases of coronavirus on Sunday and four more known deaths. The cumulative number of statewide COVID-19 cases now is 22,418 with 534 known deaths. That’s 1,700 more patients since July 2. The Nevada Department of Health and Human Services says the case counts and testing data may be artificially low Saturday through Sunday due to limited lab capacity on weekends and limited weekend reporting. But Nevada has reported its five largest single-day increases for COVID-19 cases in the past two weeks.
