CDC Sends 'Disease Detective' to Pennsylvania Amid Measles Outbreak
· Confirmed
In Short: In response to the outbreak, the CDC is sending a 'disease detective' from its Epidemic Intelligence Service to work with state health officials in Pennsylvania.

According to the Pennsylvania Department of Health, fewer than 1% of the state's cases are among those who are fully vaccinated with the MMR vaccine.
The CDC stated that about 96% of cases are among people who are unvaccinated or whose vaccination status is unknown, while 2% of cases are among those who have received just one dose of the MMR vaccine and another 2% among those who received the recommended two doses.
In response to the outbreak, the CDC is sending a 'disease detective' from its Epidemic Intelligence Service to work with state health officials in Pennsylvania.
The CDC spokesperson told ABC News, 'Pennsylvania has formally requested CDC assistance through the Epi-Aid program. In response, CDC will support the state's identified needs and strengthen its response efforts on the ground.'
The CDC is also releasing nearly $4 million to aid measles response efforts in Pennsylvania.
Lancaster County remains the epicenter of the outbreak, with 443 cases reported this year, followed by Mifflin County with 183 cases and Chester County with 90 cases.
The CDC's Erica Schwartz recommends the MMR vaccine as the most effective way to prevent measles and protect against infection.
In addition to deploying a 'disease detective,' Pennsylvania has expanded vaccination efforts in affected communities.
The CDC has previously sent teams to other states with large clusters of measles illnesses, including Kansas, New Mexico, South Carolina, Texas, Virginia, and Wisconsin.
What this adds
The CDC's measles outbreak website currently acknowledges two of the six reported deaths and lists the other measles-related deaths in Pennsylvania as 'under review.'
