For policies like quarantine following travel does it make any sense to distinguish anyone whether they have had covid, had a vaccine, had both a vaccine and covid, or had neither a vaccine or covid? Aren’t all of the above equally capable of carrying and transmitting the virus?
Yes, but measures like the policies in question encourage people to get infected with symptomatic COVID so that they could go to doctor and get that very useful piece of paper.
That's the point. If you wanted to ensure people to not get COVID, do not give those who have had COVID pleasant exemptions. They failed, they should not be rewarded.
If everyone will get it, then no one who gets it and does not die or become seriously inconvenienced has failed. Dying, of course, is usually a fail, but literally everyone will do that, too.
>Aren’t all of the above equally capable of carrying and transmitting the virus?
No. If I had Covid a month ago and recovered then baring a compromised immune system or new variant I am not going to get it again this month. So I am not "equally capable of carrying and transmitting the virus" compared to someone who "had neither a vaccine or covid".
I understand that you would have antibodies and it be very unlikely if you carry the virus it would be unlikely to overwhelm your immune system in that time, but you can still carry/spread it right?
More directly related to the policy in question they can test you for antibodies, and maybe it is immaterial, but do they distinguish if you had covid 1 month ago vs 3 months vs 6 months? So does it work on the honor system or are they testing for antibodies, is it simply a matter of if you had covid at any point it doesn’t matter if you still carry antibodies you are not subject to quarantine?
