In a statement by the CDC, the number of cases in the United States for measles has nearly reached 700, which is the highest number since measles was eliminated in 2000.
“The high number of cases in 2019 is primarily the result of a few large outbreaks – one in Washington State and two large outbreaks in New York that started in late 2018. The outbreaks in New York City and New York State are among the largest and longest lasting since measles elimination in 2000. The longer these outbreaks continue, the greater the chance measles will again get a sustained foothold in the United States.”
“Stopping these measles outbreaks is a priority for CDC and we are working 24/7 to protect Americans from this contagious disease. Vaccination is the best way to protect against measles. Today, the overwhelming majority of parents choose to protect their children with vaccines, and we’ve seen high and stable immunization rates in the U.S. for several years.”
“The recent outbreaks started through importation. Measles is imported when an unvaccinated traveler visits a country where there is widespread measles transmission, gets infected with measles, and returns to the United States and exposes people in a community who are not vaccinated. When measles is imported into a community with a highly vaccinated population, outbreaks either don’t happen or are usually small. However, once measles is in an under-vaccinated community, it becomes difficult to control the spread of the disease.”
