The situation reminds me of when I took a first aid course: When it came to the instance of someone with a bleeding wound, the instructor said, “The rule is ‘Direct pressure and elevate’.” To stop the bleeding, use a sterile pad, place it over the wound, press and hold it there and elevate the wound (if possible) above the level of the heart. If you cannot easily find a sterile pad, use what ever you can find. If the victim survives, you can deal with infections later. If the victim bleeds out, infection is not an issue.
The most important thing is to ensure that as many people as possible survive the pandemic, and we can then try to put things in order. If too many people die, even if they are not "critical to sustaining your lifestyle, the “economy” will still be in major trouble.
