Sound spiritual advice from the Reformer Martin Luther on the pandemic even before modern medicine (no, I'm not joking):
Use medicine; take potions which can help you; fumigate house, yard, and street; shun persons and places wherever your neighbor does not need your presence or has recovered, and act like a man who wants to help put out the burning city. What else is the epidemic but a fire which instead of consuming wood and straw devours life and body? You ought to think this way: “Very well, by God’s decree the enemy has sent us poison and deadly offal. Therefore I shall ask God mercifully to protect us. Then I shall fumigate, help purify the air, administer medicine, and take it. I shall avoid places and persons where my presence is not needed in order not to become contaminated and thus perchance infect and pollute others, and so cause their death as a result of my negligence. If God should wish to take me, he will surely find me and I have done what he has expected of me and so I am not responsible for either my own death or the death of others. If my neighbor needs me, however, I shall not avoid place or person but will go freely, as stated above. See, this is such a God-fearing faith because it is neither brash nor foolhardy and does not tempt God.
Moreover, he who has contracted the disease and recovered should keep away from others and not admit them into his presence unless it be necessary...
