Literally every pharmacy over here sells treatment against malaria – many have it in stock and even if they don't, they'll be able to get it for you within a few hours. Every major city (certainly every city with an airport where you could catch airport malaria) has a hospital with a department specifically for infectious and tropical diseases, where they'll happily take care of you. GPs ask you if you've been to the equator lately if you go see them with high fever. I'm not sure how a country where malaria is not common at all would be able to do any better?

Also, as I mentioned in another comment, airport staff are instructed to watch out for malaria symptoms precisely because airport malaria is a thing.

Something definitely went wrong here but from afar it surely doesn't look like a healthcare failure to me. Maybe the deceased stayed home, thinking they had caught a cold and would be able to sit it out?
