Researchers show how coronavirus spreads on planes

Based on study of two Covid-19 cases, researchers concluded that on airline flights seating proximity was strongly associated with increased infection risk and causing clusters of substantial size.

Both cases were on long flights early in the pandemic before airlines began requiring face masks, and were in the business class where seating arrangement is spacious, CNN reported.

In one of the two cases published in Emerging Infectious Diseases Journal, it was found that a young woman, who had a sore throat and cough as she boarded a flight from London, had already infected 15 other passengers during the 10-hour to Hanoi. 

The young woman and her sister had traveled across Europe early in the pandemic, visiting Milan and Paris before heading to London.
