The epidemiology has been fairly clear on this in regard to who are the most vulnerable. Certainly, they are people who are the most frail in our community, and it's quite horrible when you look at Canada and the statistics for Canada. Initially, when you were looking at the mortality rates, particularly, almost 85% of people were from long-term care and seniors homes.
Because they're the most vulnerable, they tended to unfortunately pass quite quickly. You'll see that the numbers now have gone down to about 65%. However, when you look at the reason they have dropped from 85% to 65%, it's that people may be living outside of a long-term care or seniors retirement home. They are also the people who may have multiple comorbidities and tend to be above 65 years of age.
The epidemiology for me is fairly clear. Dr. Halperin, would you like to comment?
