VANCOUVER -- The B.C. Centre for Disease Control has added 26 flights to its list of COVID-19 exposures since Wednesday, bringing the total number of B.C. flights with the disease on board in the last week to 52.

Anyone who was on any of the flights listed should self-monitor for symptoms of COVID-19, seeking testing and self-isolating if any develop, according to the BCCDC.

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

While studies have shown that transmission of COVID-19 on airplanes is rare, there are some examples of it happening. 

International travellers bound for Canada are required to show proof of a negative COVID-19 test before boarding. They're also required to self-isolate for 14 days upon arrival, the first three nights of which must be spent in a government-approved quarantine hotel.

B.C. does not impose any testing or quarantine requirements on incoming domestic travellers, but health officials have been strongly discouraging non-essential travel within Canada for months.

B.C. has also restricted non-essential travel within the province, prohibiting travel between the Lower Mainland and either Vancouver Island or the Interior. As of Friday, 127 vehicles had been stopped at roadblocks between the Lower Mainland and the Interior, but no one had been forced to turn around, according to RCMP.
