Beyond southwest Washington, where the outbreak began, cases have also surfaced in Multnomah County, Deschutes County and King County.

Measles symptoms include a fever, rash, cough, conjunctivitis (red watery eyes) or a runny nose. But measles is still a big problem in other parts of the world, and travelers infected overseas can bring the virus back and spread it, causing periodic outbreaks.
