Thank you for your question. I will answer it in English.
What I can say is that we have taken every measure possible to mitigate the risk of acquiring COVID throughout the entire journey. This includes the process of checking through the airport; the wearing of a mask, even at the arrival at the airport; the reduction of personnel allowed into the airport unless they have a verified boarding pass; the separation and proper social distancing within the airport; boarding by zones, from the back to the front; handing out protective gear, including hand sanitizer, wipes and masks; and the mandating of wearing masks throughout the flight.
As my colleagues at WestJet have noted as well, the frequent air exchange is at the hospital OR-level HEPA filtration; and even on arrival, all the sanitation measures are in place. With that cascade or multi-layer risk mitigation, we feel that we have reduced the risk as significantly as possible with respect to the journey.
