COVID-19 (Coronavirus Disease)

COVID-19 is a respiratory disease that can cause severe illness. COVID-19 spreads easily from person to person when someone who is sick breathes out droplets and very small particles with the virus. These droplets and particles can be breathed in by other people or land on their eyes, noses, or mouth and make them sick.

The Wisconsin Department of Health Services (DHS) recommends the following prevention strategies to prevent COVID-19 infection.

  • Stay up to date on COVID-19 vaccines.
  • Get tested for COVID-19 if you have symptoms or were exposed to someone with COVID-19.
  • Stay home if you have COVID-19 or COVID-19 symptoms.
  • Seek treatment if you have COVID-19 and are at risk of getting very sick.
  • Wear a well-fitting mask when recommended.

With widespread access to vaccines, testing, and treatment options, we have more tools than ever before to prevent severe disease.
