And this is classic mumps.
I only really know what mumps is supposed to look like because when I was a child in the '70s, there were still generations of adults who had experienced it first-hand. It showed up in the children's books and cartoons they wrote and illustrated (like Alligator Pie).
Now, however, these diseases seem to be poised for a comeback.
Between 1912 and 1916, 26 out of every 1000 reported cases of measles resulted in death. (It was down to 1/1000 by the '50s.) Mumps had occasional complications such as meningitis, hearing loss, and my favourite: "painful testicular inflammation." Rubella is most dangerous to the fetuses of pregnant women.
