I expect norovirus and rotovirus D&V will decline but salmonella will rise. Maybe even accidental mushroom poisoning, ptomaine? (Foraging, tinned meat) and bad salami caused an outbreak of life threatening kidney and other problems in South Australia some years back, so people going into cured meats be warned.
I'm not too worried about alcohol poisoning RE: home stills. It's people who don't toss the heads and tails that have a bad time: methanol poisoning sucks, and is the cause of most home distilling dangers (blindness, kidney failure, etc).
This is what I suspect most people will miss. Worldwide I think alcohol poisoning is adulteration of spirits with industrial alcohol but the heads and tails are not just methanol, it can have metal and chemical residues as well.
Alcohol poisoning from home stills is a constant.
