Yes, those are absolutely factors. As I had outlined earlier in terms of the overall condition of the infrastructure in homes, especially older facilities, they were designed for a different generation, a different type of individual who required care. When we look to who we are caring for today, these are people with much more complex conditions than when these homes would have been built 20 to 30 years ago. The room configuration, the overall design and layout of the building, does put people closer together. When we think about things such as isolation and cohort planning, those become very significant factors in the overall prevention efforts against COVID.
We also have to remember that from the beginning of this outbreak to where we are today, we have learned a tremendous amount, especially as it relates to asymptomatic transmission. When we look at the homes that have experienced the most significant outbreaks, that was a critical factor as well, as staff introduced that into the homes and didn't realize the extent of their illness.
