Pennsylvania's state health department reported on Tuesday that a fourth death linked to measles has occurred within the last month, marking the first such deaths in 35 years. The latest victim is an 18-year-old from Mifflin County who was unvaccinated and died due to complications from a rare neurological condition caused by measles. Another recent death involved a 40-year-old woman with asthma and severe lung disease from Jefferson County, also unvaccinated. Both deaths were confirmed after thorough investigations involving county coroners' offices. The health department attributes the outbreak to declining vaccination rates; over 700 cases have been reported this year in Pennsylvania alone, with nearly half requiring hospitalization.
