Andrew, thank you for you question! I can’t see any argument for inentionally infecting people. Ethical implications aside, we aren’t actually sure who the most/lease susceptible populations are at this point. We have seen cases of young and otherwise healthy people coming down with severe illness from COVID-19 and in some cases dying from it. So, in theory this wouldn’t fit the science as a responsible thing to do.
True, social distancing can’t last forever, but it can give us time to both lower the rate of infection and to develop drug therapies or immunizations. Until we see the Ro going below zero, though, I believe we should stay house-bound. Thanks for the question!
