Measles

Measles is a highly contagious virus that spreads through the air and can cause serious complications, especially in young children and infants. Although measles was once considered eliminated in the United States, cases are increasing in areas with low immunization rates.

For more information on data visit websites such as the Centers for Disease Control and Prevention (CDC) or the Wisconsin Department of Health Services (WI DHS).

How Does It Spread?

  • Through the air by coughing and sneezing, even up to 2 hours after a person with measles has left the area.
  • By breathing contaminated air or touching surfaces with the virus.
  • You can spread measles before you even feel sick.
  • 90% of people who are not vaccinated will get measles if they’re exposed.

Signs and Symptoms

Measles symptoms can start to appear 7–21 days after exposure:

  • High fever
  • Cough
  • Runny nose
  • Red, watery eyes
  • A red rash that starts on the face and spreads downward

Prevention

The MMR immunization protects against measles, mumps, and rubella. According to the Wisconsin Department of Health Services, two doses are about 97% effective at preventing measles. You can learn more about the recommendations in the prevention tab on the Wisconsin Department of Health Services website (Measles Information link above).

Where Can I Get an Immunization?

What if You're Unsure About Your Immunization History?

If you are looking for your immunization records, you can start by checking the Wisconsin Immunization Registry (WIR). If you previously lived in another state or country, your records may not be in WIR. Here are tips for locating old immunization records. If you can’t find your immunization record, talk to your medical provider about getting a measles booster.

Being fully immunized not only protects your health—it also helps you avoid disruptions in your daily life. If you're not protected and are exposed to measles, you may be required to quarantine at home for up to 14 days—or longer, depending on the specific situation.

Having records of your MMR immunizations or getting immunized is a step you can take now to help ensure you can keep doing the things that matter most, even if there's a case of measles in your community.
