IIt is possible to have a very low level of the virus in the body with a negative test result or it could be they've caught it on the flight back maybe. Mask-wearing on flight for example might just have helped.2 friends went to Calle Di Mijas in Spain to shut their apartment down for the winter, both tested on their return home as they operate taxis. One caught it, the other didn't, not sure how this can happen but I'm sure we'll find out in years to come.
Also i think the swab only determines if COVID is present. I don't think it determines if the person has ever had it - blood test would show if the non-affected might have had it before.
