What would you change if you take the test and come positive?
- More likely to strictly adhere to the lockdown - Post recovery / quarantine period, if (big IF) you now have immunity and aren’t risking infecting others anymore, you could be more productive in the world.
- Helping others with their food/supplies/whatever. Heck, even spending more money on take out food which helps the economy.
The idea of building up a herd immunity seems to me to require knowing who has the immunity so we know when we have enough.
