 I believe you found that there has not been a corresponding increase in critical care unit admissions despite these more severe cases. Why do you think that is? Yeah, there may be a number of reasons why that is. Part of it may be the hospitals and the availability of beds. Some of these cases will come in severe and the emergency departments are actually monitoring them and managing them and they're able to discharge them at the end of the time period. And I think we see that to some extent at the University of Virginia.
