Back in 2003 I was a junior doctor working at a Chicago teaching hospital.
As one of the newer docs, my daily appointment schedule had lots of openings. Pretty much any assignment nobody else wanted came my way.
One morning the nurse who managed our clinic told me that my first patient for the afternoon may have been exposed to a deadly virus while he was traveling in Asia.
My job would be to dress up in a medical hazmat suit, examine him and figure out whether he should be quarantined.
