Furthermore, I would like the person (age approx. 11) who tries to save the young girl to DIE of hypothermia and for the girl to recover. Could a pre-existing condition be exacerbated by the hypothermia?
Also, if it makes a difference, this would be in 1979 USA, not in the present day.
Thank you for any help!
ETA: Thank you so much for your help, I'm definitely going to go with pneumonia instead as that seems much more realistic.
