The Puget Sound Measles Outbreak

Breaking News – there is a new case in King County (see below)

Everyone is likely familiar with the large outbreaks that we have been seeing this year in New York (Brooklyn and Rockland County), Michigan, and the Pacific Northwest.

There have already been 79 cases of measles in Washington so far this year.

After all, those outbreaks make up the majority of measles cases that have occured so far this year.

The Puget Sound Measles Outbreak

Have you heard of the latest outbreak?

This one, also centered in the Pacific Northwest, began with exposures to a traveler with measles at Seattle-Tacoma International Airport on April 25.

“A Canadian resident from British Columbia who traveled to the Seattle area in late April 2019 has been diagnosed with measles. The traveler, a man in his 40s, has since recovered from his illness.

Prior to arriving in King County, he spent time in Japan and New York during the period that he was infected, two places that currently have measles outbreaks. This case has no connection to the recently-ended measles outbreak based in Clark County, Washington state.

While he was infectious with measles, he spent time in the Seattle area at several locations, including popular tourist attractions and Sea-Tac Airport. Anyone who does not have immunity to measles through vaccination or from previously having measles is at risk for infection if they were at a location of measles exposure.”

Those exposures have led to cases in:

  • King County – 6
  • Pierce County – 2
  • Snohomish County – 1

The latest case is a six-month old infant in King County, with exposures at the Seattle Children’s Hospital Emergency Dept on May 24.

“This case was a household contact of a person diagnosed with measles earlier this month, and was not exposed to measles in the community.”

With exposures in Bothell, Lynnwood, Mill Creek, Orting, Bonney Lake, Puyallup, Renton, Auburn, Issaquah, Woodinville, Kent, and Seattle.

And that’s what has led to the name Puget Sound outbreak. The Puget Sound is an inlet of the Pacific Ocean along the northwest coast of Washington, near Everett, Olympia, Seattle, and Tacoma.

How big will this outbreak get?

Immunization rates in the Puget Sound area are a bit better than in Clark County, where the last Pacific Northwest outbreak was centered.

It’s anyone’s guess at this point, keeping in mind that all it would take is for one of these exposures to be in a “pocket of susceptibles” with low immunization rates to start a big outbreak.

And all it would take to stop the outbreaks is for folks to get vaccinated and protected, understanding that vaccines are safe and necessary.
