Comparing coronaviruses, SARS-CoV and SARS-CoV-2, there are some similarities and differences. One of the differences I would say is that SARS was, in large part, an illness that we saw in hospital settings. Although it was in the community to be sure, we had outbreaks within our acute care facilities, and it was a very hospital-centric problem for the most part.
COVID has of course been through the community, and we've had very limited transmission within acute care institutions. I think we learned a heck of a lot from our experience with SARS in Canada, particularly in the Toronto area, and that, I think, is generalized across the country. Long-term care homes, however, are a very different story. Whereas it was not an issue back in 2003, one of the defining issues of this outbreak is how long-term care has been hit.
Ebola is very different, and I worked in Ebola treatment units with very few staff and a very different sort of clinical context. There are a lot of psychological similarities, and patients can get very sick, but there are a lot of differences in the clinical presentation. It's a very different kind of disease.
