I’d also just add to my other reply that long Covid might be a good justification for attempting to limit it with a zero covid lockdown. Half of people who tested positive for the virus, including those who were asymptomatic or had mild symptoms, reported breathing difficulties, nausea, fatigue, or loss of eyesight 3 and 6 months later in a study. This is because of silent hypoxia, which scientists believe happens even in some mild and asymptomatic cases. This is where blood oxygen levels drop to a dangerously low point, but with no additional symptoms or delayed symptoms. However, for those which silent hypoxia is not deadly, it does seem to significantly weaken the body long term.
