To philosopher and common saychel: You seem to believe that Hashem expects nothing of us regarding our health and the health of others. That is colossally wrong. You also fail to make any connection between the mitzvah of chesed and an obligation to protect others from your infections by wearing a mask and taking other precautions.
And philosopher, not all viruses are the same. Death rates from viruses other than COVID is generally low, whereas death rates from COVID is, well, a deadly pandemic.
