The primary reason we don't die from malaria is none of the above: it is mosquito abatement via intentional habitat destruction and copious use of effective pesticides. Large portions of the US used to be malaria country: not a spe mof it is now, and if there was a malaria outbreak in a US suburb we would wring our hands about the consequences for about five minutes and then dump enough chemicals on that subdivision to save an African country.

Ditto Europe, by the way.
