People did not walk from China to Europe, America, India, South Ameeica and so on.... There was no testing anywhere early on and even the testing today is not 100% accurate.

By not wearing a mask presents just another risk in the many ways one can pass on their germs to anyone they come in close contact with... anyone can be asymptomatic and infect others without even knowing they are a carrier.

I would never dare not wearing a mask in fear of me spreading my germs to someone else ... the same way a surgeon and staff wear a mask while performing open heart surgery, so their germs do not fall into an open body and not because they do not want to catch heart disease.
