Seems those most at risk are indigenous folk who travel, lose their immunity, and go back to stay in "local conditions."
Don't know much about treatment, I'm at the other end (prevention.)
Pilots and air crew sometimes seem to be a little "Maverick" (unruly rather than Tom Cruise) about the situation the last time I checked, but that was some time ago.
Recovery is usually full, in the UK, but I think we lose about 4 travellers a year here. Schools of Tropical Medicine usually give the most robust advice about prevention and treatment.
