Pennsylvania doctors adjust pregnancy care as measles outbreak spreads

Pennsylvania is experiencing a severe measles outbreak that has infected more than 975 people and resulted in five deaths, including two infants in Lancaster County and a newborn with congenital measles from an unvaccinated mother. At least 50 pregnant women have been diagnosed, leading obstetricians such as Dr. Sharee Livingston and Dr. Kevin Ault to revise counseling and testing protocols. Doctors report a surge in patient concerns about the impact of measles on current and future pregnancies, and many are now ordering immunity bloodwork before conception.

The state Department of Health recorded 977 cases and 53 among pregnant women, while CDC data show over 3,800 U.S. cases this year, mostly among the unvaccinated. New AAP guidelines warn of a 25-30% transmission risk to newborns when the birth parent is infected shortly before delivery, and stress supportive care for affected infants. Health officials are urging vaccination before pregnancy, as the MMR vaccine cannot be given during gestation.
