A couple of things are relevant, and we have seen a change since the spring. The pattern of illness is one that is seen in pandemics, that middle group of previously healthy. For whatever reasons, their immune system is not able to cope, or they develop a complication like myocarditis or something like that, which leads to arrhythmia and death. It is unpredictable, but what we have seen, certainly in the ICU review, is that for those who present late, those who are initially getting well and get sicker, we recognize that this is an important sign that you may either have a secondary infection or something is happening that's different. If you have severe illness or shortness of breath--as you have seen through the summer, our messaging has been pretty clear about the importance--if you have these signs or a more severe disease, get medical treatment as soon as possible.
We have seen a change. For example, in the spring we saw a number of pregnant women in ICUs. We're just not seeing that anymore. Unfortunately, we've now had around 200 deaths. But when we look back, if we'd seen the patterns...if we hadn't got the antivirals out there in communities, if we hadn't got the work with the ICUs around sharing of best practices, we would be seeing a considerably greater number. So continuing that message even after people are immunized is going to be important.
Finally, the more people who get immunized, the risk of spreading it to someone, who we can't predict will have a severe outcome, is less. Clearly, if people are getting sicker at home, they need to be seen, and the antivirals have proven an effective treatment, and not just if you get them early. Even for those who are going sour, starting antivirals at any point rather than waiting improves your outcome.
