Mask is not your enemy
Lot of experts insisted that mask is useless for preventing COVID-19. For example, this one:
By the way, her face expression is so arrogant.
And many insisted that masks have been “Scientifically” proven to be ineffective against viruses.
To be “Scientific”, you need to conduct experiments to prove the hypothesis. design a experimental group and also a control group. to make the conclusion more “Scientific”, you’d better also create more sets of those groups.
Wait, is it even ethical to ask a control group of people be exposed to the coronavirus? and do you see any research papers on this topic? none.
Lot of Wuhan cases already show evidences that the virus is contiguous in asymptomatic stage. Coronavirus is not like SARS or other virus. this virus has the highest infectious just before the symptom showing up.
Wearing mask can’t 100% protect your from breathing in virus, it can definitely slow down the virus spread out in case your are an asymptomatic carrier.
The below chart may not provide a necessarily causations relationship, but don’t you see the correlation between the curve and mask wearing?
If you have mask, please wear it when you are going out. if you don’t have, we can together find a way out. Don’t be a ostrich. Reject mask won’t drive away virus.
