Please note changes made to the weekly general surveillance report.

The report now captures reported diseases and events based on Event Date, except for tuberculosis which was not changed. The State’s surveillance system automatically populates Event Date based on the following in hierarchical order: date of onset, date of diagnosis, date first reported to county, date first reported to state, and the date the investigation was created in the surveillance system.
The report now summarizes year to date (YTD) total investigations (including confirmed, probable, suspect, and non-cases) created for all diseases and events, by public health jurisdiction. See YTD – All Conditions on the last page of the weekly general surveillance report.
