This might sound funny to some people but there are lot of people in this world that believes Corona virus is fake. ( think like a red pill person ) reference from the movie "The Matrix". I'm really excited to see what you guys think about it 
You simply can't make anyone believe anything on purpose - its personal choice in the first place.And their choice has some benefits - if corona is fake then they can go outside, connnect with people and etc.
However, downside is - they can be wrong, catch a virus and die eventually which is not nice at all.
