Geisinger Medical Center in Danville, Pennsylvania, has enacted stricter visitation policies for its neonatal intensive care unit (NICU) following the diagnosis of measles in a visitor who had been present in the unit between August 14 and August 17. The hospital is taking these measures as Pennsylvania faces a significant increase in measles cases, with the state recording two measles-related deaths this week, the first such fatalities in the nation this year and the first in Pennsylvania in 35 years.
The NICU, which provides care for premature and critically ill infants, is particularly vulnerable. Patients in this unit are often too young to have received the measles vaccination and are susceptible to serious complications from infectious diseases.
Under the revised policy, only parents or legal guardians of NICU patients are allowed to visit. These individuals must be free of measles symptoms and will undergo screening upon entry. Visitors are also strongly encouraged to wear surgical masks. The hospital has stated that these temporary restrictions were carefully considered to protect its most vulnerable patients.
Nationally, the U.S. has reported 2,777 measles infections this year, marking the highest number of cases since 1991. Pennsylvania has been significantly affected, ranking third in the country for measles outbreaks with 424 cases. The area surrounding Montour County, where Geisinger Medical Center is located, has reported 10 cases. This region has a notable Amish and Mennonite population, communities that have historically shown lower vaccination rates and may be less inclined to seek testing if infected.
The two measles deaths in Pennsylvania occurred in Lancaster County, which is considered the epicenter of the state's outbreak. Measles is highly contagious and can lead to severe health issues, especially in infants and young children. The Centers for Disease Control and Prevention recommends the MMR vaccine for children starting at 12 months, with two doses offering a 97 percent reduction in infection risk. For infants in NICUs, the risk of severe illness from measles is amplified due to immature immune systems and a potential lack of maternal antibodies.
Measles can remain airborne for up to two hours after an infected person leaves an area and can infect up to 90% of unvaccinated individuals exposed to it. Complications can include hospitalization for one in 20 infected children, encephalitis (brain swelling) for one in 1,000, and death for up to three in 1,000. The implemented restrictions aim to minimize the risk of pathogen transmission to these vulnerable infants, a practice mirrored in other intensive care settings during periods of high disease prevalence.
