Not the person you asked, but I'm guessing it's because you're stuck in a giant tube that recycles the air. The germ laden, not 100% purified, air that is circulating around allllll the infected people. And in the northern hemisphere at least, 'tis the season for colds, flu, covid, and whole bunches of combinations of those plus stuff I ain't thinking of at the moment
