The outbreak has been particularly deadly, with the state reporting five measles-related deaths, including a tragic case of a 20-year-old Amish woman with leukemia. The surge in measles cases has prompted school districts across Western Pennsylvania to prepare accordingly, while experts examine the reasons behind this outbreak amidst vaccine skepticism.
