Staff who had direct contact with Covid-19 patients showed a positivity rate of 20%. The question of whether or not having COVID will protect you from getting it in the future, similar to chickenpox, is ongoing.

If detectable antibodies do begin to wane a few months after an infection then these kinds of tests are not helpful in measuring cumulative population exposure.
