The agency attributed the high number of cases primarily to a few large outbreaks — one in the state of Washington and two others in New York City and New York state. The New York outbreaks are among the largest and longest lasting since 2000.
“The longer these outbreaks continue, the greater the chance measles will again get a sustained foothold in the United States,” the CDC said.
Health and Human Services Secretary Alex Azar said, in a statement, said the rise in measles cases is “avoidable.”
“Measles is not a harmless childhood illness, but a highly contagious, potentially life-threatening disease,” he said. “We have the ability to safely protect our children and our communities. Vaccines are a safe, highly effective public health solution that can prevent this disease. The measles vaccines are among the most extensively studied medical products we have, and their safety has been firmly established over many years in some of the largest vaccine studies ever undertaken.”
