The CDC reports 16.3 flu/pneumonia deaths per 100,000 [0]. That's 0.0163 percent. Johns Hopkins University reports covid-19 has 278.89 deaths per 100,000 - a 1.2% mortality rate in the US [1]. That would put covid-19 at 278.89/16.3 = ~17 times more deadly than the flu. Just because the numbers don't hold for a particular age group doesn't make the aggregate statement false. In fact, it would be misleading to categori…

That is misinformation. The actual COVID-19 infection fatality rate calculated by the CDC is 0.6%, not 1.2%. https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burd...

The JHU site that’s linked is reporting case fatality rates, not infection fatality rates

It’s also not estimating case under-reporting like CDC is

I think jumping straight to misinformation is a bit strong here, but it’s important to make fair comparisons and discuss the context of the stats along with the raw numbers

Ugh, do you not realize that the vaccine does not stop you from getting and transmitting the virus?

Why is this downvoted? It's technically correct and supported by studies (look it up). Vaccinated people can and do get and transmit the virus. Frequently without even realizing it. It doesn't mean vaccination isn't required as it's proven to significantly reduce mortality especially among the older population.

> It's technically correct

That doesn't prevent it from being misleading. Both vaccinated and unvaccinated people can get and transmit the virus in the same sense that both I and Sidney Crosby can play hockey.

That failure to acknowledge anything besides "complete prevention" v. "not complete prevention", as if to imply that vaccination is entirely useless for preventing infection and transmission, is why people - myself included - are downvoting the above comment. To assert that vaccinated people can transmit COVID without providing the necessary context re: actual probability of that happening relative to unvaccinated persons is to lie by omission.

99%+ eventually getting infected is more likely. Multiple countries already have confirmed infections over 10%.

The CDC estimated that about 44% of Americans had been infected as of October 2021. We're probably well over 50% now due to the Omicron wave. https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burd...

the CDC quite likely skews low, given the political ramifications. i've heard non-governmental estimates as high as 80% at this point. my expectation is that 2/3 of americans have had it, which is roughly borne out in my anecdotal experience, particularly since omicron. i think that's why we're seeing the mediopolitical machine starting to relent on covid policy in the past few weeks (that, and it's an election year).

It probably does reduce transmission because it helps your body defeat it more rapidly, in some cases so quickly that you don't even notice you had it. More rapidly = less time to transmit it to other people.

I've seen reports that say that if you have Covid, you transmit it as easily as anyone else, regardless of vaccination status. That is why we see so many people saying that the vaccines don't prevent you from spreading it. However, if you're vaccinated, you're less likely to get it in the first place, so from a standing start, you're less likely to transmit it. And since at some point everyone was covid-free, this is…

To piggyback on this a bit:

> I've seen reports that say that if you have Covid, you transmit it as easily as anyone else, regardless of vaccination status.

While you're indeed infected, yes. If that duration for vaccinated persons is shorter than the duration for unvaccinated persons, then the obvious deduction would be that the shortened duration results in a lowered overall chance of spread - even if (indeed, especially if) the viral loads are equal (as vaccine-skeptics like to assert as if it's some sort of "gotcha"). Transmission is a function of viral load × time, so shorter time = shorter window of transmission = less risk of transmission.

Factor in the reduced chance of being infected in the first place (as you point out), and it becomes obvious on both fronts that vaccination reduces the spread of COVID, Omicron included.

On the other hand, if you're vaccinated, you're less likely to have symptoms, so you're less likely to notice that you're infected.

On the third hand, if you're unvaccinated this long after vaccines have become generally available, that tends to correlate with ignoring symptoms as "allergies" or "seasonal cold" and ignoring the possibility that you're infected. The people dragging their feet on getting vaccinated ain't typically the ones taking quarantines seriously.

re normal life china. bave you ever visited /r/china ? read the stories of people living in china and how life is 'normal' there and pls report back

/r/China has unfortunately become increasingly dominated by Americans who have little to no knowledge of China. It's one of the most bizarre national subreddits, in that it's become a forum for people outside the country to hate on the country. I speak Chinese and know lots of people in China. That's how I know what's going on. I'm not reliant on Reddit threads. My friends in China have been doing normal things throu…

I can back you up on this. I lived in China in 2017-2018 and have friends in Guangzhou, Shenzhen, Shanghai and Beijing. As skeptical as I am of Chinese reportings, it really does sound like they've kept Covid under control for the last year and a half. Everyone I know there is doing normal things and has moved on with their lives, with the caveat that -- as you said -- international travel is all but impossible. A few of my friends who went on vacation outside of China during Chinese New Year 2020 have still not been allowed to go back.

A few months ago, a Shenzhen friend said she had to go on a business trip to Shanghai, and was a little worried because there had been 2 reported Covid cases in the last few weeks. Another friend, earlier in the pandemic, would mockingly send me US statistics of million of Americans getting Covid, and that it's nearly eradicated China.

It frightens me to think of what means they took to get these ends, but I really do believe they have it under control.

Adding to this, I'm not sure I had COVID, but 1) I had cardiac troubles before the pandemic, 2) did many months of bike to gain back some average cardiovascular health 3) I got vaccinated in Jan, and now my heart is doing different things (less fatigue but more and larger skipped beats). It's hard to know what's causing what now. I assume a lot of people are in the same case.

Similar to me. I am (was?) a healthy mid-fifties life-long cyclist and the first dose (Moderna) caused 10+% PVCs that I'm now on beta blockers to try and manage. Both my doctor and now cardiologist have advised me against receiving the second shot.

I guess covid is gonna make a lot of us cardiovascular specialists ..

I wish you a good recovery (as much as possible)

I had Delta once. Prior to it I would ride 30 miles on my bike like it was a breezy day. When I'd take breaks to vacation or whatever I could pick back up easily. A year after COVID, I'm struggling to hit 20 miles and I lose my progress easily. I'm not sure it's COVID related, but nothing else has changed in my life.

How old are you?

I'm in my early 30s

Did you take the vaccine?

Yes, I did. I have both shots and a booster. That said, this all started before the vaccines. The day before I got COVID I returned from a 30 mile trip with my buddy. I had COVID in January, and vaccines were available until months later, so I don't think it's really vaccine related.

Back in my 40s I broke my leg: a simple tib-fib fracture. Without any artificial fixation it took 3 years to recover. There's plenty of tissues in a human body that can take more than 1 year to fully regenerate.

Heart muscle doesn't though.

From what I remember from a family members heart attack ... the heart doesn't really heal.

Hence pace makers for a lifetime.
