I'm going to start off.
Asthma, allergy, and COPD are all definitely related. There are over three million Canadians suffering from asthma, and millions more from allergies. Asthma is an allergy.
If you look at the English-speaking world that I referred to in my remarks, when you look at New Zealand, Australia, England, the United States, and Canada, why do those five particular countries have such a severity and pronounced aspect of these diseases? There are reasons, and I'm going to ask Dr. Latycheva to comment.
