And those are the good outcomes. Fortunately the #1 killer outcome (measles pneumonia) is rarer now thanks to oxygen and antibiotics (while they still work.)
Measles encephalitis? Roll the dice. In my lifetime (until the 60s) measles was the #1 cause of deafness and blindness in the USA. Now we’ve closed the schools for the deaf and blind, but with a little work they could open again. Of course the encephalitis doesn’t always cause deafness and blindness. Sometimes it just plain kills, but also some survive it. I don’t have the stats on that.
And then there’s Subacute sclerosing panencephalitis ( SSPE ) – no cure, often fatal. You look it up if you like, I don’t need it before lunch.
