We can't predict whether Covid 19 virus will live with us for many years. So wearing mask, hand sanitising and social distancing are compulsory to protect ourselves from this pandemic.
Two likely approaches regarding these precautionary measures:
Everybody who is standing near me is a virus carrier. I must not be transmitted this disease from them. So I must follow all the precautionary measures.
I don't know whether I am virus carrier or not. Nobody must be transmitted this disease from me. So I must follow all the precautionary measures.
Both these approaches will protect us from this disease. But their social impact in future would be different indeed, I believe.
I believe choosing a good philosophical approach has great significance especially while exhorting citizens in the scenario of suffering and loss.
