Clinical Testing Data Surveillance
In collaboration with other public health partners, the WSLH has developed data-driven statewide respiratory and gastrointestinal pathogen surveillance programs in Wisconsin. Weekly reporting of diagnostic testing data to WSLH is important so that public health partners know what communicable diseases are impacting community health in Wisconsin. The complete Laboratory-based surveillance plan for the 2025-26 season is available at the bottom of this page.
Wisconsin Respiratory Surveillance Program:
The aim of this program is to gain situational awareness of the respiratory pathogens circulating in Wisconsin, including geographic spread and positivity rates. All Sites in Wisconsin performing PCR/molecular and/or rapid antigen testing for respiratory pathogens are asked to submit their testing data on a weekly basis (number tested, number positive) all year round.
Wisconsin Acute Diarrheal Illness Surveillance Program:
The aim of this program is to gain awareness of the gastrointestinal pathogens affecting community health in Wisconsin. The WSLH requests that clinical labs submit gastropathogen PCR testing data for bacterial, parasitic and viral pathogens on a weekly basis (number tested, number positive), all year round.
WSLH Clinical Surveillance Data Reporting Migration:
Effective July 1, 2026
Effective July 1, 2026, WSLH will transition clinical surveillance data reporting to a new portal. Please review the details of this migration below:
Reporting Timeline
- Data through Week Ending – June 27, 2026: Continue reporting data using the current Survey Alchemer portal.
- This portal will remain available until September 1, 2026, to allow completion of 2025–2026 season reporting.
- Data from Week Ending – July 4, 2026, and beyond:
- All 2026-27 data must be reported through the new REDCap portal
Accessing the New REDCap Portal
Each laboratory will be assigned a unique reporting URL. To obtain your URL:
- Click the “Report Clinical Surveillance Data 2026-2027 Season” button below.
- Enter your Lab ID* in the designated field.
- Your custom reporting link will appear.
*Your Lab ID is the same username you use to log in to the Survey Alchemer reporting portal. It consists of a series of uppercase letters followed by numbers (e.g. LRN999).
Please note: Your URL will remain the same and can be saved or bookmarked for future use.
For assistance, please contact WCLN@slh.wisc.edu
Updates for the 2026–2027 Season
Please see below for a summary of updates WSLH has made to data reporting requirements for the 2026–27 season.
- Optional entry of Chlamydia pneumoniae and Mycoplasma pneumoniae results
- Optional entry of Norovirus typing (GI/GII) results
- Optional entry of RSV typing (A/B) results
- Expanded list of testing platforms
Instructions for submitting surveillance data using the new REDCap Portal
Surveillance Data Distribution
The WSLH aggregates all respiratory and enteric pathogen data and provides summary reports in the bi-weekly Laboratory Surveillance Report, which is distributed to over 600 recipients across the state.
Graphs of aggregate surveillance data for a variety of pathogens can be navigated to using the links on the left-hand side of this page. The graphs include both current and historical graphs and, in some cases, both statewide and regional data. Descriptions of Wisconsin’s laboratory-based surveillance programs are also available on these pages.
