Indeed this may even help understand why the case of exactly 2 people in an office results in higher absences (50%) than the 3-6 case (36%): You develop a more personal relation with that other person and they're usually not too much of an annoyance, so out of respect for them you stay home when sick. When you are in a more crowded office this mechanism doesn't kick in because, frankly, you likely hate them at least a bit, and that would explain the lower %. Finally when packed in a chicken farm scenario, all these mechanisms go out of the window and the sheer amount of germs, noise, distraction and stress you're exposed to trumps every other factor, hence the highest reported (62%) value.
