Waukesha County Measles Update
(Updated February 2026)

While there are no active cases in Waukesha County at this time, there are active cases in Wisconsin. Measles remains highly contagious and can spread quickly if introduced into a community. Residents are encouraged to:

  • Review their MMR (measles, mumps, rubella) vaccination status
  • Access records through the Wisconsin Immunization Registry (WIR)
  • Contact their healthcare provider or local health department with questions

According to DHS and the Centers for Disease Control and Prevention (CDC), measles is preventable through vaccination. Children should receive two doses of MMR vaccine, and adults without evidence of immunity should ensure they are up to date. Vaccinations are available through healthcare providers, select pharmacies, and local health clinics. Waukesha County Public Health will continue monitoring measles activity statewide and nationally and will provide updates if needed.

What Happens If a Child Is Exposed to Measles and Is Not Fully Vaccinated?

1 – Exclusion or Quarantine May Be Required (14 Days Minimum)

State law requires schools to exclude students who are not fully vaccinated during a measles outbreak if they may have been exposed. These requirements are determined by Wisconsin state statute and the Department of Health Services (DHS). Local public health departments follow this law. Here is how it applies:

  • If a child has received only 1 MMR dose: They are not quarantined, but they are excluded from school and school activities because state law requires 2 documented doses for full measles immunity. Once they receive their 2nd MMR, they may resume all school activities.
  • If a child has received 0 MMR doses: They are quarantined, which also means excluded from school and all activities.

The exclusion or quarantine period is 14 days and starts 7 days after the exposure.
If additional cases occur, the 14-day period may restart or be extended.

During this time, students may not attend:
• School or childcare
• Sports or extracurricular activities
• Public events or gatherings

 

2 – Monitor for Symptoms

Symptoms can develop 7–21 days after exposure. If symptoms develop for you or your child, please call your healthcare provider before going to a clinic or hospital.

Signs and symptoms of measles include:
Runny nose
High fever (may exceed 104°F)
Tiredness
Cough
Red, watery eyes, or conjunctivitis (“pink eye”)
A red rash with raised bumps appearing three to five days after initial symptoms, starting at the hairline and moving to the limbs. 

 

 3 – Post-Exposure Protection May Be Recommended

Healthcare providers may recommend the MMR vaccine within 72 hours of exposure. If an MMR is administered within 72 hours of exposure, that eliminates the need to quarantine.

 

According to DHS and U.S. Centers for Disease Control and Prevention, (CDC) measles is preventable through vaccination. DHS recommends all children receive two doses of the MMR vaccine before age 4. Additionally, people born before 1957 are considered immune and do not need a vaccine. All other adults without laboratory evidence of immunity should have at least one dose of measles-containing vaccine, and children should have two doses. 

Individuals who are pregnant, severely immunocompromised, have young children under 12 months, or are otherwise ineligible for the MMR vaccine should seek guidance from their medical provider. 

Vaccinations are available through healthcare providers, select pharmacies, and local health clinics.

Suspect case: An individual with measles-like symptoms who is being evaluated.

Isolation: The separation of people with suspected or confirmed illness from those without illness. 

Quarantine: The period of home isolation recommended for non-immune contacts who have not received appropriate PEP within the specified time period. 

Exclusion: The temporary restriction of individuals who have been exposed to a confirmed measles case from high-risk settings, defined in section 7, during the incubation period to prevent potential transmission. It may apply to contacts who are not otherwise quarantined. 

Laboratory evidence of immunity (titer): Detectible measles IgG antibody.

Passive symptom monitoring: Self-monitoring for symptoms of measles. 

Active symptom monitoring: Where a susceptible contact communicates with public health regularly to assess for symptoms consistent with measles. The self-monitoring module within a WEDSS contact investigation may be used to facilitate active monitoring.
