you layer testing, oral antivirals, monoclonals, and masks on top of that but we need to do all of it. this is not a joke. omicron is still dangerous, and we have to employ all those strategies and techniques. >> i mean, sanjay, i guess my question is and -- and it was partly asked. but i mean, just overall, one day -- i mean, is that what happens to viruses? that they -- they gradually weaken over time, and is omicron a sign of that weakening? or is it just a -- this one happens to be a weaker variant and there's -- could be another variant that's way stronger than delta coming down the pike? >> well, i think the second part of your sentence is -- is still true. we don't know that if there is potentially another variant which could be more problematic than omicron down the pike. but, you know, if you look sort of historically at viruses do tend to become, at the same time they become more transmissible, oftentimes, become less lethal. sort of trading off lethality for transmissibility. and, you know, we are seeing that with omicron. um, and -- and if you look overall, we are 90% of the case
