Local Case Counts

We update confirmed and probable case numbers for the county and by city weekly. Hospital data is updated each weekday. Depending on when you check the tables, numbers may vary from those reported by the state Department of Health. Because new reports of positive tests come in and disease investigations are done throughout the week, the numbers vary based on when the data is run. Please check the "Data as of" or "Last Updated" note to confirm the most current number.
