A couple of weeks ago I got an e-mail from my son's middle school alerting families that several students had been diagnosed with whooping cough, also called pertussis. I didn't pay too much attention; my son has been vaccinated and he got a booster shot a couple of years ago so I hoped he would be protected.
Then I started to cough.
A visit to my doctor and a pertussis test confirmed that I am one of the 338 people infected with it in Oregon this year. That's three times higher than last year.
