Apparently Nobody Is Sick In Bend...
...or obviously nobody's using Who Is Sick, where just a single person in the 97701 zip code has a runny nose. Portland, on the other hand, looks more like a mess with 128 reported sicknesses throughout the metro area, all plopped onto a handy Google Map (and unfortunately, you can't directly link to specific cities, so you'll have to search by city when you get there).
But it wouldn't matter if anybody used this in the grand scheme of things anyway, as folks will still send their sick kids to school, passing on illnesses to all the other kids, which in turn pass it on to the parents, who then pass it on to co-workers. But I'm not bitter. Really.
