Note well it says NOTHING about the source of the outbreak.
Here is what the CDC says about mumps:
Mumps is no longer very common in the United States, but outbreaks continue to occur. Outbreaks have most commonly occurred in places where people have had prolonged, close contact with a person who has mumps, such as attending the same class, playing on the same sports team, or living in the same dormitory.

"Close contact with a person who has mumps", but "mumps is no longer very common in the US". This implies the source is someone who brought it into Washington State from somewhere OUTSIDE the US. Now who could that be?
Here is a list of "sanctuary cities" in Washington State:
- The following Washington counties do not honor ICE detainers: Benton, Chelan, Clallam, Clark, Cowlitz, Franklin, Jefferson, King, Kitsap, Pierce, Skagit, Snohomish, Spokane, Thurston, Walla Walla, Whatcom, Yakima. (Added 10-13-15, Source: 10-8-14 DHS DDO Report)

And according to the The Seattle Times, illegal immigration is up 14% in the state. You can read about it here:
Now, I'll be the first to admit these numbers do not prove anything in particular. But they do suggest that immigration is a possible source of the mumps virus responsible for this outbreak.
Which would you rather do - continue to expose your children to dangerous vaccines, or have the US government screen people for disease before they are allowed into the country? We used to do this at Ellis Island; what's the reason we cannot do this now?
