Interesting. I would be curious to know how exactly they determine which rows they think "may have been effected".

Taking a quick glance at the online data, it appears that on almost every flight there are either 6 or 7 rows "effected" (presumably because someone in a single row tested positive, and they count the 6 rows around them). There are a couple of other cases where they must be using some other metric (an Air Canada flight from Delhi to Vancouver with rows 12-14 and 31-34 effected, a few listed the effected rows as "unknown"). But there seems to be no accounting for other obvious factors eg length of flight: the standard "6 or 7 rows" is applied for short hops (on Delta from SEA-YVR, which is going to be well under an hour) versus long, globe-spanning flights (Turkish Airlines longhaul from Istanbul to Toronto)...both show 7 rows effected. Hmm. Yes, I get it that this is not a sophisticated measure. Still interesting.

This (stats on routine potential covid exposure on flights) is not something I've seen before, and I suspect it's not widely know. I have a feeling the airlines would like to keep it that way.

Given this information, it would seem relatively easy to determine the number of passengers that were exposed to coronavirus who subsequently were infected. They've got the contact information, seat number, age, sex, country of origin etc. Seems like a perfect case study.

Indeed. The data currently posted online only goes back covering the period from September 9-22. I wonder how long they have been collecting this data (anyone know?), and if they are doing anything with it, other than pinging those who were within +- 3 rows of someone who tested positive.

Is Canada testing all passengers arriving on international flights? Well, that seems unlikely as they also have this data on domestic flights. Maybe this comes just from people who self-report testing positive later (or after being hospitalized?) and then they disclose their recent travel history?

Of course, there are lots of other parameters that could impact infection/spread....flight duration, number of known positive passengers on the same flight, seating load, aircraft type (large widebody jet, or small regional turboprop, etc.)... But even if imperfect, I agree, this is valuable data, and I would hope they are doing a quality, ongoing study using it. Anyone know if they are?

Data goes back months. Each province is responsible for doing its own contact tracing however generally the infection rate is sufficiently low that they can do contact tracing and build the correlations between testing data and exposure. They have also been looking at the genetic makeup of the virus samples. They would be able to tell if this is the mutated version in Italy or if it matches the original version from China etc.

Everyone entering Canada is required on entry to be able to articulate a plan for their 14 day quarantine, including where, who will delivery groceries etc. Local health authorities and police have been following up. If the person can't articulate a plan, the government will play host.

Good, I'm glad (and not surprised) to hear that they have this in the hands of competent people. Oh, if only those of us to your south enjoyed the same (counting the days...115 to go...).

But they're not just tracking this for international flights: they have similar data posted on the same website for domestic flights (same website). That suggests they are also interviewing passengers who deplane from a domestic flight...unless they're getting this info some other way? Seems unlikely, but what do I know, I'm from south of the 49th parallel...

The health authorities are doing contact tracing. If you test positive they try to figure out who you have been in contact with for the past few days/week. If you were on any flights it ends up on a list and they try to contact the people you may have been in close contact with for testing.

The airlines even for domestic flight are now required to collect and provide information to the health authorities when requested. What is surprising in this day and age of everyone being worked up about security the airlines were not collecting contact information for everyone on the flight. If you booked through a travel agent and did not have a frequent flyer number on the flight, the airline had very little information about that individual.

There are also regions of Canada that have implemented quintinite rules even for people traveling from other parts of the country. COVID is easier to handle in a big city not so much in a smaller community.
