The thought occurs to me.
Everything is the current strategies assumes that everyone will eventually be infected, and the effort should be to “flatten the curve”. However not everyone is equally at risk from the virus. There would therefore be a case for offering a managed infection. essentially get prepared, self isolate, open a vial of virus , inhale, and ride it out. Three weeks later you should test clear. Essentially as effective as immunisation, but riskier and not always pleasant. But a person would be clear to work, help others, travel. As more and more took this route herd immunity would rise, and would rise faster than in the current system where we are trying to lower the value of the exponent, which has the unfortunate effect of slowing down the herd immunity.
There are lots of problems with this. One could only offer it voluntarily, the ethics would be difficult at best, and the liability issues impossible in some places.
However, these are not ordinary times. Personally I would more than happily sign up. The risk reward makes sense to me. I have very elderly parents, and right now I worry that I can’t help look after them. I’m already working from home, and the city has just had cafés restaurants and bars shut down. Maybe I would be too ill to work for a while, but that is assumed to be on the agenda anyway. If I could get it done with now in a controlled manner I could be useful, and be able to look after my parents. Right now is the worst answer. It is assumed I will eventually get sick and need to isolate, but nobody can control when, and for this entire time I can’t look after my parents effectively, or help anyone else.
