This isolated case emerges against a backdrop of rising national measles infections, with over 1,900 confirmed cases this year, marking the highest count since measles was declared eliminated in the U.S. in 2000. Three deaths have been reported as of December 9.
While measles is easily spread, particularly among unvaccinated individuals, Connecticut maintains exceptionally high vaccination rates. Over 98% of its students receive the MMR vaccine by kindergarten, the highest rate nationally, underscoring the effectiveness of public health efforts.
