One 18-hour flight, four coronavirus infections

New York Times reporting: Given the variables, infectious disease specialists have had a hard time determining the risks of flying. But a study published on Wednesday provides some clarity. After an 18-hour flight from Dubai landed in Auckland, New Zealand, in September, local health authorities discovered evidence of an outbreak that most likely occurred during the trip. Using seat maps and genetic analysis, the new study determined that one passenger initiated a chain of infection that spread to four others en route.
