My paternal grandfather had a severe tremor that was dubbed “Parkinson’s” but he didn’t look like any PD patient I’ve ever seen, and it didn’t progress. We believe that he probably had that influenza; he was an adolescent in 1918. My dad said, “You used to see other people like that around, but you don’t any more.”
That disease did things to people that couldn’t be predicted in any way.
During the 2014 Ebola outbreak, one of my friends posted on Facebook that her then 15-year-old daughter came to her in tears, afraid that we were all going to die from Ebola. Mom dried her tears and flipped open the laptop to show her why that was extremely unlikely, and then it transformed into a long talk about AIDS, something she first learned about when she was about 15 and unlike Ebola or influenza, we didn’t know at the time what caused it or exactly how it was spread, or how to treat it either.
ETA: Around the same time, she mentioned that her then 8-year-old daughter came home from school with a permission slip for a flu shot to be given by the school nurse, and said, “I want you and Daddy to NOT sign it.” (They’re divorced but she sees her dad all the time.) Nope, little one, you’re getting that shot!
There’s an Ebola outbreak now in the war zone in the Congo, which is why we aren’t hearing much about it, in addition to no known non-Congolese being affected (yet). I sure hope it burns itself out the way most of the other outbreaks did.
