CDC sends a disease detective to Pennsylvania as its measles outbreak reaches 1,222 cases
The CDC is sending an Epidemic Intelligence Service officer, a so-called disease detective, to Pennsylvania after the state requested help through its Epi-Aid program, ABC News and 6abc reported. Pennsylvania’s outbreak has reached 1,222 cases and six deaths, concentrated in Lancaster, Mifflin and Chester counties. None of those who died were vaccinated, the state said. The CDC is also releasing nearly $4 million for the response. The U.S. has recorded 4,410 confirmed cases this year.
Measles spreads fast where vaccination rates are low, and a county without its own health department struggles to trace contacts. Federal help shows the outbreak has outgrown local capacity.
Check that you and your children have two doses of the MMR vaccine, especially before travel to affected counties. Unvaccinated adults can also get the shot.
Health Secretary Robert F. Kennedy Jr. blamed Gov. Josh Shapiro for not accepting CDC help sooner and said the issue was resolved this week.
State officials have emphasized that the outbreak is still growing and that the CDC's help arrives after weeks of local response, so the federal role now is support rather than leadership.
Confirmed: case and death counts from the state, the CDC deployment. Not confirmed: when the officer arrives. Watch whether weekly case counts begin to fall.
