The outbreak started west of Philadelphia and has hit Lancaster County hard, home to the nation's oldest and largest Amish settlement. The Amish, a religious group that rejects most modern technologies and government intervention, have been disproportionately affected. Five of the six victims were from Amish communities, local media reported.
Braxton Mitchell, co-director of the University of Maryland's Amish research program, said the community's highly social, large-family lifestyle creates a unique risk for rapid virus spread. 'The Amish get together with their neighbours, with their relatives; they have church services on Sundays which tend to be at somebody's house and the whole church district shows up,' he said. Professor Mitchell added that many Amish believe 'if we get sick, if God's will is that we're meant to survive, we'll survive', and are wary of government-mandated medicine.
Steve Nolt, a professor at Elizabethtown College who has lived in Lancaster County most of his life, said non-Amish residents are worried, warily monitoring transmission alerts for schools, stores and other locations where the virus has spread beyond Amish areas.
In neighbouring Chester County, which has reported 93 cases, public health director Jeanne Franklin said the reported numbers likely understate the problem. 'What we're seeing is the worst of the worst,' she told the ABC. 'Statistically speaking, we're likely going to see more deaths.' She described the Amish as 'vaccine hesitant' but said public health messaging should target everyone who chooses not to be vaccinated, regardless of background. 'Thirty years ago you may have said: Why do I need that? Measles isnt an issue. Well, guess what, its an issue.'
Health authorities have administered more than 6,000 MMR vaccines at 212 pop-up clinics in affected communities since April. The outbreak comes amid a national surge in measles: the US has recorded over 4,500 cases this year, the highest since 1991, and the CDC says vaccination rates have fallen below the 95 per cent coverage needed to prevent outbreaks.
The outbreak has sparked a political clash. Pennsylvania's Democratic Governor Josh Shapiro, who has advocated for vaccines, faced attacks from Health Secretary Robert F. Kennedy Jr, who suggested Mr Shapiro may have 'altogether fabricated' the deaths and accused him of 'fearmongering, misinformation, finger-pointing, and the weaponisation of infectious disease fears for political gain.' The CDC initially did not list the deaths on its public dashboard, saying it needed more information, a move Mr Shapiro condemned as allowing misinformation to spread.
