They were being lied to at one time (maybe not on purpose -so that may make it less of a lie and more of a case of mistaken info being passed onto them.). Amazingly enough, the first "scientific facts" were the ones that were wrong - which I happen to believe is the case with the virus. It is only your arrogance that makes you think you are right and everyone who believes differently than you is wrong.As the world became round, the earth was uncentered and the earth began to revolve around the sun there were many who believed they were being lied too, because well they just knew.
