There is some evidence that a person that is infected by this corona virus has some level of resistance to illness that lasts for a variable amount of time, but can still harbor and spread the virus.

Sounds just like a vaccinated person. The resistance comes from antibodies. Are the antibodies different? Can you take a blood test from a person and differentiate between antibodies created as a result of having been infected versus antibodies created as a result of having been vaccinated?

The resistance is more likely due to functional memory T cells, not due to antibodies. Detectable antibody levels seem to fall over time, and many people with mild infection do not develop significant antibody levels. Antibodies are more of a imperfect marker of past infection.

I, too, wondered about whether immunity via infection vs. immunization varied going forward. Forum member Indah posted a link to a Salt Lake Tribune article that does a fine job of explaining the basis for believing there may well be a difference.

Minor point; antibodies are part of lasting immunity, not all of it. There are also T-cells that may recognize a prior invader. This came up way back, in an article, as people were concerned antibody levels dropping off after some exposure (virus infection or vaccine candidate back then? Don't recall which) might mean losing immunity. Thankfully, there's more to it.
 
Minor minor point. There are many viruses where antibody levels confer no immunity. Hepatitis B, Hepatitis C, HIV, as examples. There are vaccines for two, not one yet for the last.

Excellent article and a good explanation of the difference between sterilizing immunity and effective immunity but did not explain the difference between vaccinated protection and recovered protection. There was no data that a recovered had higher type A mucous antibodies than the vaccinated.
 
There is little functional or detectable difference. The reason for the test requirements for entry into a country, even if the traveler is functionally immune from prior infection or vaccination, is to reduce the chance of the traveler bringing in disease that the people at his destination are not yet functionally immune to. It’s like why we can’t bring fresh food from the mainland to Hawaii or the other way around.

But that's precisely the point that some of us are making. There is no test requirement for those "functionally immune" due to previous covid but there is for those "functionally immune" due to vaccination, when as you say there is little detectable difference.
 
Will they pay for my temporary replacement at my job?
If your profession is in jeopardy, one shouldn’t travel.

The PCR test has been shown to be positive up to 90 days beyond clinical recovery from an infection that is severe enough to seek medical attention, and certainly in patients that require hospitalization, so would mark these people as infected and possibly infectious when in clinical experience they are not.
