idk much about drugs or disesase but there's a reason variola stopped being a thing way faster here thn arfirca and mid east and indonnssa and short of a large scale amount of animal product being contmnnd ur probably not going 2 die
and a 90% death rate is way better than 50% if ur not infected because one of the big reasons an ebola out break had such a hard time was because it killed people before they spread shit
altho spanish flu had a 10~20% mort rateso ur probly bufkcd mite as well selfkill
