Health officials in New Zealand, a country that has a strict 14-day quarantine in place for arriving travelers, released a case study on Friday that details the risks of traveling on long-haul flights during the coronavirus pandemic — even if negative coronavirus tests are required before the flight.

The report details a coronavirus outbreak linked through DNA analysis to one passenger on an 18-hour flight from Dubai to New Zealand in September. The traveler, who tested negative for the coronavirus with a polymerase chain reaction (PCR) test within 48 hours of the flight, was contagious but pre-symptomatic onboard the plane, and infected at least four other passengers.
