*All data are provisional and will change. In order to rapidly report COVID-19 information to the public, data are being reported in real-time. Information is constantly being entered into an electronic system and the number of cases and deaths can change as additional information is gathered.  Information for deaths previously reported has changed, therefore, today’s numbers have been adjusted.  For health questions about COVID-19, call the hotline at 1-800-889-3931 or email
