Entering Singapore’s Changi Airport gives the visitor a glimpse of a mask fetish. Security guards wear it. As do the nurses and the various personnel who man cameras like anti-aircraft batteries, noting the approaching passenger in transit with due suspicion. The passenger, in turn, wishes to avoid showing anything that might be construed as a suspect symptom. Whatever you do, do not cough, splutter or sweat in nervousness. Best to wear a mask then: neither party can accurately gauge the disposition of the other.
