SeaTac, Wash. - Three King County residents may have been exposed to measles on a flight from Amsterdam to Sea-Tac Airport in late March.

Health officials say a woman on the flight has a confirmed case of the disease, and now they are contacting passengers who sat near her.

The Northwest Airlines flight 33 came from the Netherlands to Sea-Tac on March 26, and arrived in Washington at about 3:25 p.m. The woman - who is in her 20s - then flew from Seattle to Portland on Horizon Airlines Flight 2243, which departed from Seattle at 5 p.m.

Health officials say passengers who were on her flight or in the airport at that time should be alert for symptoms and contact health providers if they become ill.

Measles is a highly infectious illness that causes rash, fever, cough, and red, watery eyes.
