stomach bug going around in Pacific NW?

[mamaonthefarm]

Is there one? My preschooler threw up last week and then had loose poops for a week and threw up one week after the first vomitting episode. What is this?
Now another kid is throwing up and now I am queasy. Is something going around right now? How long does it last?

Ack - I hope not! But there's always something going around this time of year.
