First though, the definition of risk is the severity of an outcome multiplied by the likelihood of it occuring. The severity of omicron is almost certainly less than that of delta, but because it is more transmissible, you're more likely to get it.
Plz expand on the math. The probability I would eventually get exposed to the delta variant was essentially 100%. The transmissibility of the omicron variant just means it will happen sooner.
Well you've got a bit of a strawman argument going here, and we'll have to agree on definitions.
One part of the risk calculation that I didn't mention was time. To use an example from an endemic disease, you're chances of having the flu at some point in your life is essentially 100%. Basically everyone gets the flu at some point, and many people get it multiple times. The probability of you getting the flu in any given period of time is considerably less than 100%.
There are many people both vaccinated and unvaccinated who have never been infected with covid, so we know the probability is not 100%. That's strawman.
Now you didn't say infected, you said exposed to. That probability might be closer to 100% depending on your definition of exposure. Exposure does not equal infection.
What we're really looking at is the probability of being exposed, and then the probability of being infected given an exposure. We're pretty settled on the fact that omicron spreads more easily, so given an exposure, you're more likely to be infected. With more people being infected, you're going to have more opportunities for exposure, which will lead to more infections, which will lead to more exposures, and so on...
Again, we know that there have been something like 60 million covid cases in the US, so the probability of being infected is well below 100% (it's actually less than 20% if you just go with the simple probability). Let's say omicron increases that to 30% or 40% or 50% (we have no way of knowing yet what it will be), at some point, the increased number of infections will lead to an overall increase in hospitalizations.
Does that make sense?
