One government official who is a doctor said that you have to consider everyone as a carrier of the virus. Any stranger should be a suspect. Having that mentality will keep you safe from infection since you will be keeping your distance from people. And people means any person whether relatives, friends or strangers.
I think we are entering the era of the new normal. There is no more socializing like before that even a handshake or a hug cannot be done anymore. We have become isolationists and I think that is for our own benefit.
Do you wear a face mask and face shield?
