Not only do individuals not want to spend time in the hospital, we as a society don't want them there either. Assuming we need 60% of the population to recover in order to achieve herd immunity, and assuming we somehow isolate all of our 65+ year olds from the virus, that would mean almost 2M hospitalizations in the US.
4,548 "healthy" hospitalizations (16% of deaths under 65 have no comorbidities. Using same rate here).
800k-1.2M infected w/o comorbidities depending on "healthy rate"
4,548 / 1M = 0.45%
You have to go to the very young (under 25) to find a sizable population without a comorbidity.
I think it is more useful to point out that mortality is skewed heavily toward age and whether or not you are in a nursing home. Seniors outside of nursing homes are doing an order of magnitude better than those in homes.
Over half of US counties have no COVID deaths. The number are skewed terribly by NY/NJ as well.
Looking at it another way, if the entire population were healthy, that’s 160.000 deaths. That’s four times the number of yearly traffic deaths, double the number of overdose deaths (both already high for comparable countries)
Those 160.000 might not return every year, but if this behaves as a typical virus, it could mutate enough to return every few years.
According to CDC data, 81% of deaths from COVID-19 in the United States are people over 65 years old, most with preexisting conditions. If you add in 55-64-year-olds that number jumps to 93%.
For those below age 55, preexisting conditions play a significant role, but the death rate is currently around 0.0022%, or one death per 45,000 people in this age range.
Below 25 years old the fatality rate of COVID-19 is 0.00008%, or roughly one in 1.25 million.
As I point out in the thread, even estimating 50% of people under 65 have an underlying illness (lets say thats 25% under 17, 50% 18-44, and 75% in 45-64 to roughly get us there) moves the "Under 65 healthy IFR" only up to 0.09%.
If that's true (and I don't think it is) that's a serious problem.
BTW smoking is not a comorbidity, it's an habit that could or could not develop a comorbity given enough time.
I believe you are underestimating how bad US society is in regards to healthcare and how much they overestimate some condition (like blood pressure related hearth diseases) to avoid reimbursing insurance bills.
