This will almost always be the case, people die from staph which is our own natural flora first line defense.
Since test kits are caught up and there even antibody versions, we need random sampling to determine exposure levels. Compare exposure levels to hospitalization rates, if high exposure and low hospitalization, release all quarantine from those areas.
Early on it was necessary to ensure that the lethal/requiring care varieties were contained and the mild/asymptomatic allowed to spread. Given the increasing rates of positive tests and low hospitalization in most areas i think we're there.
