No place has seen anything close to 50% infection rate though. How long would it take to get to a 50% infection rate? Years? Decades? How much will be learned and applied toward improving the survivability of COVID-19 in that time? China is currently sitting at 56.1 cases per 1 million citizens after 3 months, and the number of new cases has declined sharply. 5-20% of the US population gets the flu each year, but there are probably a lot of repeat offenders in that group. People that get the flu more often due to age and health concerns. To get to a point where 50% of the population has had COVID-19, could easily take 10 years.
If we extrapolate China's numbers for cases/1 mil of population, we'd have 18,513 people contract the virus in the US. 1% mortality rate means 185 deaths over the next 3 months if the rate of infection and mortality both follow the same pattern as China.
So far, the US is seeing just 4.1 cases per 1 million citizens, but that's expected to climb as more testing kits become available, and some suspected cases are confirmed.
But China took measures that probably are not possible in the US so I am not sure that China is a great thing to base our thoughts around as far as how transmissable the virus is. I also feel like 50% is probably overstating it but using flu here is bad comparison as there is a flu shot which a not insignificant part of the population has. Also we have some antibodies built up from previous exposures to the flu.
But even if it is 20% and it seems in general about 20% of cases need more care that could quickly overwhelm our health care system. We have even less spare beds and respirators then Italy so a heavy localized breakout could be very bad.
Yeah, you could also say that China has a higher percentage of the population that smokes, that their government didn't communicate much if anything with their citizens until the situation was dire, and that they tend to have much higher population density than the US. Which all makes it a perfect breeding ground for a virus like this. My crystal ball is no better than anyone else's, but I'd bet that it's not quite as bad in the US.
If we look at Hubei province specifically, as basically the worst case scenario and saw similar numbers in the US this is what it would look like (I think you actually did this math once already in one of these virus threads):
According to the WHO's most recent update on the virus, (sorry it's a PDF) Hubei province has a population of 59170000 people. There have been 67707 confirmed cases, with 2986 of those resulting in death. That means that 4.4% of those infected in Hubei died (as ground zero it took time to understand what was occurring and react, therefore has a mortality rate 1% higher than the overall rate of 3.4%). And it means that 0.11% of the population was a confirmed case, and 0.005% of the population died.
Extrapolate those numbers to the US and we'd have 363,000 confirmed cases and 16,500 deaths in 3 months. As you noted when you did similar math, that's about average for a flu season. Regardless of how you feel the US gov has responded to this situation, they've had a 3 month head start that China didn't get where they've known about this and had time for the entire international community to learn, react, and plan. I think that fact, coupled with the lower population density, likely means that the US won't be impacted as badly as Hubei has been. I'm not saying that it shouldn't be taken seriously, and I'm happy that so many businesses seem to be acting proactively to try and head the situation off. But it's easy to lose perspective and jump to conclusions when we read headlines about more and more infections, closures, and people claiming 50+ percent of the population will get it. That might eventually be true, but it's not going to happen in the next couple of months.
Some people are going to get sick. Some of those will die. It's not going to be fun, but I'm not seeing anything that amounts to more concern than washing your hands, avoiding large gatherings, and being sensible about avoiding sick people, or avoiding all contact if you yourself are sick.
