Two Unvaccinated People Die of Measles in Pennsylvania

Pennsylvania state health officials announced on Tuesday that two unvaccinated individuals have died from measles. These fatalities represent the first reported deaths due to measles in the state in 35 years. The announcement follows closely on the heels of Maryland declaring a measles outbreak in three of its counties just one day prior. Measles is a highly contagious disease that can be effectively prevented through vaccination. The Centers for Disease Control and Prevention (CDC) states that measles is so contagious that if one person has it, 90% of the people close to them will also get it, unless they are vaccinated. The virus can remain active and contagious in the air for up to two hours after an infected person leaves an area. Measles symptoms typically appear 7 to 14 days after infection and include a rash, high fever, cough, runny nose, and red, watery eyes. Complications can be severe, including pneumonia, encephalitis (swelling of the brain), and death, particularly in young children and individuals with weakened immune systems. The measles vaccine, typically administered as the MMR (measles, mumps, and rubella) vaccine, is highly effective. Two doses of the MMR vaccine are about 97% effective at preventing measles, while one dose is about 93% effective. Public health officials emphasize that vaccination is the most critical tool for preventing measles outbreaks and protecting communities. The resurgence of measles cases in various regions highlights the importance of maintaining high vaccination rates to achieve and sustain herd immunity. Herd immunity occurs when a sufficient percentage of a population is immune to a disease, making its spread unlikely. The CDC recommends that children receive their first dose of the MMR vaccine at 12 through 15 months of age and their second dose at 4 through 6 years of age. Unvaccinated individuals, particularly those who are immunocompromised or cannot be vaccinated for medical reasons, are at higher risk during outbreaks. The Pennsylvania Department of Health has not released further details regarding the specific circumstances of the deaths or the vaccination status of the individuals beyond their unvaccinated state. However, the state health department continues to monitor the situation and work with local health departments to respond to potential exposures and prevent further spread of the virus. The Maryland Department of Health reported its outbreak on Monday, noting that the cases were linked to a specific location and involved unvaccinated individuals. This parallel situation underscores a growing concern among public health experts regarding declining vaccination rates in some areas, which can lead to the re-emergence of vaccine-preventable diseases like measles.
