Measles is resurging primarily due to declining vaccination rates, which have dropped below the 95 percent threshold required for herd immunity. Increased vaccine hesitancy and interruptions in routine immunization schedules, particularly during the COVID-19 pandemic, have been major contributing factors to this decline. Because the measles virus is highly contagious, it spreads easily and quickly through under-vaccinated communities.
