Measles alert issued for travelers to Puget Sound region

The state Department of Health is cautioning travelers to Western Washington about the potential for exposure to measles.
Four new cases have diagnosed in three counties west of the Cascade Mountains, state health officials said today, May 15. Two cases were confirmed in King County and one each in Snohomish and Pierce counties.
The cases are in addition to a case diagnosed Sunday in the Tacoma area of Pierce County and 71 cases earlier this year in Vancouver and surrounding Clark County in Southwest Washington.
All of the individuals with the new diagnosis passed through Seattle-Tacoma International Airport during the window in which they were infectious, officials said.
Other exposure information is not yet known, officials said.
Measles is highly contagious and can be spread by breathing on something, coughing and sneezing, officials said, encouraging everyone to be sure they have been vaccinated.
According to health officials, the 75 cases this year include 52 children younger than 10 years old and 15 ages 10-18.
Among adults, one person age 19-29, four ages 29-39, two ages 39-49 and three ages 49-59 have been infected in Washington state this year.
