Health officials in Colorado said there have been three additional measles cases following a Turkish Airlines flight that landed in Denver on May 13.
The Colorado Department of Public Health said a third passenger on the flight was confirmed positive for the illness, 9 News reported on Sunday.
However, the outlet said the adult patient, who lives in Arapahoe County, is vaccinated and recovering at home.
The news comes as the Centers for Disease Control and Prevention (CDC) updated its website on Friday to show that as of Thursday there are have been 1,088 confirmed cases of the measles reported by officials in Alaska, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York City, New York State, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Vermont, Virginia, and Washington.
