Michigan Communicable Disease Surveillance — MDSS Data
What this means
The Michigan Disease Surveillance System (MDSS) is the secure web-based platform that healthcare providers and labs use to report 90+ legally reportable conditions to the state in real time — from common infections like Lyme and salmonella to rare ones like Creutzfeldt-Jakob and anthrax. Aggregate reports are released weekly. MDSS data is what drives public-health response when a case cluster emerges.
What you can do
- Suspect a reportable illness? Your doctor or lab will file it for you.
- For unusual illness clusters (e.g., 3+ people sick after the same event): call your county health department directly.
- Tick-bite illnesses (Lyme, anaplasmosis): see https://www.michigan.gov/mdhhs/keep-mi-healthy/communicablediseases/ticks-michigan
- For travel-related concerns or international exposures, the CDC Travel page covers risks by destination.
