Heh. Survived but at what cost? 10% infected are temporarily disabled, 2% permanently. Unless you design it for battlefield, quick death is not a priority. In the era of directed refugee streams used as bargaining card at best, weapons at worst it’s not hard to figure out, that disabling/incapacitating a part of population is a better long-term strat than going for decimation: you burden the social services and diminish the workforc. For the record: I DO NOT believe COVID was a weapon and I DO NOT believe it leaked from a bioweapon lab.
