>> if past is prolog, the jury is still out on the wisdom of trusting everyone to do what is sensible and responsible? >> i would agree with that point. we are really notrate ready for people to have their own rules about self-isolation. that is, not to have any. there are people who are immunocompromised out there. there are people who are at risk for various reasons. and spreading the virus with fwha any kind of reckless policies isn't going to help anything. so we have to be careful here. it is good to be confident that we are coming down from this omicron wave but it's very likely, in the months ahead, we will face another noxious variant that can be really troubling. so, we don't want to be too overconfident and we don't want to abandon things that work. >> i just wondering if that new, you know, variant is already out there. subvariant of omicron known as b. a. 2. there's been a bunch of studies they found it is more contagious than the already highly contagious omicron.
