Malaria in North America and England is covered pretty well in Mann’s 1493. There are a couple kinds of malaria, one more resistant to cold than the other. No doubt the indigenous Americans had it bad, to put it mildly, but reading the accounts of early colonization efforts in that book, I mean, damn. Wave after wave of colonists, each losing 50+% in the first year (and it’s not like the survivors stopped dying then). For years on end, across multiple colonies. Mostly to disease.
