Hospital capacity and activity should be the metric that determines policy, not the number of positive cases, or even deaths. Positive cases shouldn't be a surprise. It's a highly infectious virus, of course there will be millions and millions of positives. Covid-19 deaths are not all the same. Yes a life is a life, but a healthy 30 year old dying of Covid-19 is a lot different than an 80 year old with stage 5 cancer. One died of Covid-19 and one died with Covid-19, that's an important distinction. The best indicator is the hospitals. If something is really bad, hospital beds are full, ICUs are full. Bad flu seasons have overwhelmed hospitals. As long as the health care system is in good shape, opening the economy should proceed. If hospitals are swamped, lockdowns have to remain in place.
