You believe quarantines have no effect on the spread of contagions? With data on zero-covid countries (Australia, New Zealand, China, S Korea, Vietnam,...) so readily available for comparison... I would actually fire you if you worked for me as an engineer. And for the fact that you were obviously not following quarantine procedures, for which you're now overcompensating by spreading medical disinformation. It's not hard spotting the people that caused all the deaths during covid. It's pretty easy actually.
