The equation should be much simpler.
Stay home, don't die or cause death. Realize that very few things are truly essential and solutions can be found to have them brought to you. And thank G-d that this mageifa kills less than 10% of people instead of others that kill over 50%.
The end.
You realize there's a bit of cognitive dissonance inherent in saying that nobody should go outside, but then going on to advocate getting deliveries, which necessitates people going outside for you. Milk doesn't grow on grocery store shelves, and Amazon and supermarket packages don't grow on your doorsteps.
I'm not gonna pick apart the semantics, because we agree with each other. People should minimize their unprotected outside dealings with others in order to arrest viral spread as much as possible. That being said, having
nobody go around outside is completely and utterly impossible under any circumstances. Therefore, one should daven that everyone should stay healthy, that the sick should be healed, that the mourners be comforted, and that he not be the cause of any harm to befall others. Realize, that even with all our efforts, that HKBH runs the world.
