Yeah does that. Also in a small number of patients causes a fatal neurological syndrome months to years after infection. Est 1:2500 to 1:10000 no one really knows. Lot of these diseases have far milder courses in children than adults. Polio I think is also often asymptomatic. Mumps can cause sterility. Even consider after the Spanish Flu in 1918 there was a 10 year long epidemic of sleeping sickness. That might, might not be related. Also now I'm in my 50's I have half a dozen friends who used to be healthy and vibrant who now appear to have some sort of chronic fatigue syndrome. Old age? Post viral syndrome? No idea but makes me nervous. And there are the two older people I knew who had lingering effects from polio who both died in middle age.
