In your circumstances, you would actually be better off catching it, then staying away from your household whilst you recover. That way, afterwards, you could be 100% sure you are not an infection danger to someone you come into contact with at high risk.
To use an analogy with seasickness: when you first have it you are afraid you are going to die, but after you have had it a bit longer you are afraid that you won't. I have never had seasickness, airsickness or even hay fever. My wife does, and even though she loves her garden, it makes her life a misery for several months each year. Just because I don't suffer from any of these doesn't mean that I have no consideration for those who do.
Unfortunately for Skipdiverjohn's and others' simplistic and egocentred worldview there
are worse things than death. If he were not self aware enough to feel remorse and shame that his own actions or inactions might have led to the potential death, temporary or even permanent disability of another person, then the risk of it happening to him might motivate him to straighten up and fly right. You can waffle on for ever about percentage of risk etc but if the worst happens to you yourself that will seriously mess up your world. The worst being permanent disability, chronic pain and loss of independence, and having to depend on others for everything.
So for the foreseeable future this is the "new normal" and while things may get better over time it may never be as it was before. We need to accept that, take precautions to the best of our current knowledge, which can change, and adapt accordingly. For a population brought up on instant gratification, everything "on demand", promotion of individual rights over responsibilities, it will be hard, but it must be done.
Even so, we might anticipate a second wave if relaxation of lockdown measures is not carefully controlled.
