Possible Measles Exposure at Marshfield Medical Center Emergency Department in Weston

Monday, November 9th, 2026 -- 3:01 PM

(Mike Leischner, WSAU) The Marathon County Health Department and Wisconsin DHS are investigating possible measles exposure at the Marshfield Medical Center Emergency Department in Weston.

According to Mike Leischner with WSAU, officials say the person was at the ER on Thursday, November 5th from 1:30 to 3:30 PM. Health officials are working to identify anyone who may have been exposed.

For anyone present at the location during the times listed, consider the following:

• If you have immunity from vaccination or if you have had measles before, you are well protected and at low risk of becoming infected. Monitor for symptoms and call your healthcare provider if you develop a fever or rash.
• If you do not have immunity, talk to your healthcare provider to see if vaccination or medication after exposure is recommended to help prevent illness. This is especially important for individuals at high risk for measles complications.
• If you develop any symptoms of measles, stay home (do not go to work, school, shopping, or use public transportation) and tell your healthcare provider before visiting so they can take precautions to ensure other patients are not exposed to the virus.

Those who were present and are not immune would likely see symptoms beginning November 11th. Wisconsin has seen more than 400 measles cases this year. The majority have been centered in Southwest Wisconsin, with some isolated cases in Marathon and Chippewa Counties.

Earlier this week, health officials reported one death related to the Southwest Wisconsin outbreak, an infant who was too young to be vaccinated.
