Local Case Counts

We update confirmed and probable case numbers for the county and by city daily. Depending on the time of day you check the tables, numbers may vary from those reported on the interactive dashboard. New reports of positive tests come in and disease investigations are done throughout the day, so the numbers vary based on the time of day the data is run. Please check the "Data as of" and "Last Updated" note to confirm the most current number.
