Alkis Diamantakos Posted about 1 year ago Paul Ewald: Can we domesticate germs? He addressed this when he talked about Malaria. He said that by mosquito-proofing the houses, the sick people who'd be at home wouldn't get bitten again and thus infect others. This way, only the more benign strains of malaria, those which would let people feel well enough to leave their houses and get bitten again, would be selected for. I also think that when he said "across the board", he was talking about the mentality of examining the germs from an evolutionary POV. That is, limit their transmission options to those which require a relatively healthy host.
