Australian researchers have warned travellers are still at risk of a coronavirus infection while flying and in airports after tracing 15 cases back to two passengers.

The transmission occurred despite masking requirements for passengers, functioning air purifiers, and use of masks, eye goggles, gloves and protective gowns by the flight crew, according to a report in the Journal of Travel Medicine.
Being seated within two rows of a primary case increased the risk of infection more than sevenfold, while spending more than an hour in the arrival airport increased the risk nearly fivefold, the study found.
