Measles In US Expands Beyond Major Outbreak Areas As New Wisconsin Case Reported, Philadelphia Airport Exposed

The US <span>measles</span> outbreak is showing no signs of slowing down as it has reached new locations. A new case was recently reported in Wisconsin's Chippewa County, outside the state's main southwestern outbreak area, while Philadelphia health officials are warning of a possible measles exposure at the city's international airport.

The developments are crucial as measles cases continue to increase across the US, with Pennsylvania reporting hundreds of cases and Wisconsin recording 171 confirmed cases so far in 2026.

<h2>New Measles Case Reported In Chippewa County</h2>

<a href="https://www.healthandme.com/health-news/donald-trump-wants-childhood-vaccines-split-into-5-shots-to-prevent-autism-but-is-there-evidence-article-156191678" data-type="tilCustomLink">Wisconsin's Department of Health Services</a> confirmed one measles case in Chippewa County on September 22. According to reports, the case has been attributed to out-of-state travel. 

It means that it may not be connected to southwestern Wisconsin outbreak, where cases are concentrated. The state said no public exposure sites have been identified so far. The Chippewa County Health Department is working with the infected person and healthcare providers to identify anyone who may have been exposed.

“Measles is highly contagious, so confirming a case in our community is concerning,” Chippewa County Health Officer Brittnay Herrick said. “Our public health team is working closely with partners to identify potential exposures and ensure those affected have the information and guidance they need.”

Wisconsin has reported cases in Grant, Iowa, Lafayette, Marathon and Vernon counties since August. The state's largest cluster remains in southwestern Wisconsin, where 161 confirmed and six possible cases had been reported by September 18.

<h2>Measles Exposure At Philadelphia Airport</h2>

On the other hand, Philadelphia health officials are also warning travelers about a separate possible measles exposure at <a href="https://www.healthandme.com/health-news/pennsylvania-measles-outbreak-crosses-700-cases-as-state-seeks-cdc-help-article-156179409" data-type="tilCustomLink">Philadelphia International Airport</a>. According to health officials, an infected person walked through Terminals B and F, as well as areas connecting to Terminals C, D and E, between 7:25 p.m. on September 13 and 12:05 a.m. on September 14.

The person remained inside the airport and did not leave the premises. Health officials said the airport exposure is not connected to a separate measles exposure reported recently at Children's Hospital of Philadelphia.

Philadelphia Health Commissioner Dr. Palak Raval-Nelson said, “This week's measles exposures are a reminder of how important it is for all of us to be up to date on our vaccinations.” She added that fully vaccinated people are not at high risk from the suspected exposures.

People who were at the airport during the exposure period are being advised to check whether they are immune.

Those who are unvaccinated or unsure of their vaccination status, along with infants, pregnant people who are not immune and people with weakened immune systems, should contact a healthcare provider.

The virus spreads through the air when an infected person coughs, sneezes or breathes, and can remain in the air for up to two hours after the person has left an area.

Early symptoms typically include fever, cough, runny nose and red, watery eyes, followed several days later by a characteristic rash. Serious complications can include pneumonia, <a href="https://www.healthandme.com/health-news/us-measles-outbreak-can-vaccinated-people-still-get-infected-article-156156221" data-type="tilCustomLink">brain inflammation </a> and, in some cases, death.

The Philadelphia Health Department says measles can be transmitted from four days before through four days after the rash appears, meaning an infected person can spread the virus before realizing they have measles.

People who may have been exposed should first find out if they are immune. Two documented doses of the MMR vaccine provide strong protection against measles. People who are not immune may be eligible for post-exposure treatment, depending on when the exposure happened.
