Anyone who was on any of the listed flights should self-monitor for symptoms of the coronavirus, seeking testing and self-isolating if any develop, according to the BCCDC.

Passengers who were seated in the listed rows are considered to be at greater risk because of their proximity to a confirmed case of COVID-19.

Studies suggest that coronavirus transmission on airplanes is rare, though there are examples of it happening. 

International travellers bound for Canada are required to show proof of a negative COVID-19 test before boarding their flights. They're also required to self-isolate for 14 days upon arriving in the country, and must spend the first three nights of their quarantine in a government-approved hotel awaiting the results of a second COVID-19 test.

No such rules exist for domestic travellers bound for B.C., though health officials have been strongly discouraging non-essential travel within Canada for months.

Last month, B.C. also introduced restrictions on travel within the province, with fines of $575 possible for those found to have left their health regions for non-essential reasons. 

B.C. health officials do not directly contact everyone who was on a flight with a case of COVID-19 on board. Instead, public notifications are posted on the BCCDC website.
