What does an adult with measles look like?/poison ivy

[lauradi7dw]

There was a woman on the Red Line this morning looking very miserable, covered in red spots. A quick search of duckduckgo images shows me the bare backs of adults with measles and the faces of kids. Some kind of privacy thing? I am hoping she had a bad encounter with poison ivy instead of a communicable disease. My tai chi instructor got poison ivy recently and ended up taking prednisone. I was surprised by this, thinking of rubbing pink stuff on skin rather than having a strong corticosteroid inside.
But here's a ten year old article suggesting it.
