Malaria is why the first attempt at the Panama canal failed. Kerosene is partly why it became successful.
Do you first try to heal your kid or everyone at the same time?
I had no idea of that, as I suspect many given the time past if you wasn't around then. Did a little digging and nicely covered here: https://www.cdc.gov/malaria/about/history/index.html
Which makes me wonder - what the cost of malaria drugs are and how much would it cost to eradicate it. Equally have the true environmental and ecological aspects of eradication methods been analysed. I wasn't aware that mosquito's were pollinators until a while back, not that anything usurps Bee's, but many insects are pollinators and in some area's they may even be crucial as a species.
After all the 1950's approach was basic killing of the mosquito's and whilst that may of been a solution for one area like the US, I'm not sure that approach would be taken as much today and for Africa, certainly as I mentioned, the whole pollinator aspect of mosquito's may make for a more fragile ecosystem that removal of a species would be more impaction than the gains.
I always found it fascinating that malaria has been around so long that a genetic mutation evolved in some that makes them immune to it.
Bats eat tons of mosquitoes. Some outfits encourage and help people set up bat friendly enclosures to deal with local mosquito problems.
Lets face it, if the same Malaria mortality rate happened in the West, we wouldn't (and historically didn't) wait for vaccines - we'd pave over an entire ecosystem if we had to. We'd do the same even if we had the same death rate as the group that got vaccinated.
Even rogue nanoswarms are less worrisome than mosquitos as a vector.
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.
