The British Columbia Centre for Disease Control has identified more flights on which passengers may have been exposed to COVID-19 this month.
In a tweet posted Saturday morning, the BCCDC listed the four new flights that have recently passed through Vancouver International Airport and carried at least one individual who has since tested positive for COVID-19.
The first, Delta flight 3569, travelled from Vancouver to Seattle more than two weeks ago. Additional flights flagged for potential COVID-19 exposure include American American Airlines flight 1415, which travelled from Dallas to Vancouver on July 11, and Air Canada flight 214, which departed from Vancouver and landed in Calgary on July 12.
Affected rows were not reported on either of the U.S. flights, while those seated in rows 25 to 31 while travelling to Calgary are considered to have faced a higher risk of exposure to the virus.
The most recent flight added to the BCCDC's list on Saturday, Air Canada flight 855, carried passengers from London to Vancouver on July 17. Affected rows on that flight are listed as 26 to 32.
According to the BCCDC, passengers who travelled on any domestic flight found on the organization's public exposures list should self-monitor for symptoms for the 14 days following their flight's departure.
All passengers who have travelled to B.C. from outside Canada are mandated to self-isolate for 14 days upon their arrival, regardless of whether their flight is known to have carried any confirmed cases of COVID-19.
