Note: Health officials will reach out to people who have been exposed directly whenever individuals can be directly identified. You may receive a call from a representative of Public Health Madison & Dane County to follow up on a known exposure. You can verify their employment with Public Health by calling our main line at 608-266-4821. Your call will then be routed back to the representative who reached out to you.
If you were exposed at these locations, check your MMR (measles, mumps, rubella) vaccination status and monitor yourself for symptoms.
Check your vaccination status
- If you were vaccinated in Wisconsin: You can find your records using the Wisconsin Immunization Registry (WIR) or you can call your health care provider.
- If you were vaccinated somewhere else or have incomplete records: You can reach out to the health department in the jurisdiction where you may have been vaccinated. CDC has a list of other states' immunization information systems. You can also request serology from your doctor. This is a blood test to see if you have measles antibodies.
If you can confirm you were vaccinated, it's extremely unlikely you will get measles. If you are fully vaccinated, the measles vaccine is 97% effective at preventing illness. Keep an eye out for measles symptoms just in case, but it's very unlikely you will get sick.
While most adults are considered immune with one vaccine, we strongly recommend people who are students in postsecondary education, work in healthcare, or are immunocompromised get a second MMR vaccine to be considered fully immune.
If you are unprotected and were exposed, you need to quarantine.
- Unprotected means you were born in 1957 or after and are unvaccinated or have no laboratory evidence of having had measles.
- Because measles is so infectious, if you were exposed, you will need to quarantine, which means you’ll need to stay home and not go to work, school, or any public places from day 7 after your first exposure through day 21 after your last exposure. Call us at 608-266-4821 and tell the operator you are unprotected and were exposed to measles, and we can give you instructions.
If you don't know or are unsure of your vaccination status
- If you don't know whether you've had the measles vaccine, we treat that the same as not being protected, just to be safe. That means you must stay home and avoid others from day 7 after your first exposure through day 21 after your last exposure or until you can confirm your vaccination status.
- During that time, monitor yourself for symptoms and if you start feeling sick, call ahead before going to a clinic or hospital.
Look out for measles symptoms for 7 to 21 days after you were exposed
- If you were exposed, you won't get sick right away. Measles symptoms appear 7 to 21 days after contact with the virus.
- Symptoms typically include high fever, cough, runny nose, and watery eyes. Measles rash appears 3 to 5 days after the first symptoms (see pictures of the rash). The rash usually starts on the head, near the hairline, and then the rash moves down towards the rest of the body.
If you were exposed and have symptoms of measles
- Stay home. If you develop any of these symptoms, stay home and do not go to work, school, shopping, or use public transportation.
- Call your doctor's office or clinic before visiting. Measles is one of the most contagious diseases. It’s extremely important that the office or clinic take steps to protect other people before you come to see them.
- If you do not have a provider and are not sure how to contact a clinic, call us at 608-266-4821 (Monday-Friday, 7:45 am to 4:30 pm).
