FAs aren't a representative sample of the population: they're generally healthier or at least not extremely morbidly obese, not drug addicts, and somewhat physically fit. They're typically required to pass physical fitness tests (open aircraft doors, etc.) and medical exams at regular intervals. Depending on the airline, they might be relatively young. They're also reasonably well educated and generally from a higher socioeconomic class than those with chronic health problems. Hence comparing infection rates can be misleading, although a better comparison might be to use only adults who aren't in nuring homes or similar situations and are employed full time (which life insurance companies use as a very general proxy variable for minimal health).

This is in response to the post above about aircraft cabin pressure and virus transmission. My computer doesn't seem to want to permit me to quote it. Sorry.
