A new study has detailed how a single traveller infected four others on a flight from Dubai to New Zealand, despite testing negative before they boarded the flight. The government-funded New Zealand study into the flight raises questions about the safety of international travel during the pandemic, even when the precaution of pre-flight testing is taken. In total, seven cases from the flight were identified in managed isolation and scientists believe that four of those cases picked up the virus during the 18-hour flight. That source case had tested negative on a polymerase chain reaction (PCR) test 48 hours before their flight. "These seven cases were found to have been seated within four rows of each other during the approximately 18-hour flight," the NZ study states.
