What this means
CDC and MDHHS track three main respiratory viruses each week: influenza (flu), SARS-CoV-2 (COVID-19), and RSV. They use a combination of test-positivity rates, hospital admissions, emergency-room visits, and (newer) wastewater surveillance. Levels are reported as Minimal, Low, Moderate, High, or Very High. Peak respiratory season is December through February.
What you can do
- Wash hands often. Cover coughs. Stay home when sick.
- Get a yearly flu shot — Michigan offers free vaccines at most pharmacies and county health departments.
- Update your COVID-19 vaccine annually if you're 65+, immunocompromised, or pregnant.
- Older adults and infants should ask about RSV vaccines (Arexvy, Abrysvo, Beyfortus for infants).
