As well, 150 flight attendants and 30 pilots are currently in quarantine, which is down from the previous 300. This high number is due to suspected cases of the virus on various Air Transat flights.
Hennebelle explains when there is a suspected case of the virus on a flight, all employees are immediately isolated.
He also says all those who could’ve come in contact with the individuals who have tested positive, fellow employees or otherwise, have already been advised by public health agencies and have also been advised to self-isolate.
