CDC officials said the agency had been contacted about the individuals by health officials in New York, California, Illinois, Texas and Washington. The majority of U.S. measles cases originated from unvaccinated U.S. residents returning from places where large outbreaks are occurring, including Israel, Ukraine and the Philippines. In 2014, when the United States had 667 measles cases, two people with measles were placed on the list and were kept from travel. Nonetheless, the record number of measles cases this year has led to 62 airplane-related investigations of contacts of people with measles who were on flights. In addition, health officials work with airlines to eliminate change fees.
