Thank you.
Dr. Mossman, I was very interested in reading a little about the research you've done, understanding the interactions between viruses and their hosts.
One of the issues with COVID-19 has been that presentation of symptoms has been quite varied from individual to individual to the extent that, even though there is a national case definition, some provinces have tweaked it as more and more becomes known.
From your perspective looking at host cells, as you have explained to us, what exactly are you learning about this particular virus and the variation of presentations? To give you another little piece of background, we've heard from Genome Canada, in terms of the virus mutating and therefore changing as time goes on, and potentially even that an individual's genome might receive the virus differently.
Could you comment on that?
