The R0 is unknown. It was based on initial data from China. Also, R0 is malleable. It partly is a function of the virus but also a function of how people respond to the virus.
You don't know though, under normal circumstance, how many will get the disease. It is only estimates, and most estimates have been horribly off.
Your logic doesn't really make sense. How can a virus that spreads this quickly have a low R0?

"Restaurants will reopen with fewer tables and masks will be commonplace."

I find it hard to eat with my mask on. Do they mean for staff only or is there going to be a weird mask dance at every table of take mask off, take a bite, put mask back on, take mask off, take a drink, put mask back on, and repeat?

The mask statement wasn't tied to the restaurant statement. I would assume you take off masks while you're eating. And servers & others will wear masks.
 
No it's not. Also, which estimates have been horribly off? I'm not aware of any that have been way off other than conservative estimates about hospital ventilator requirements (which would obviously be biased towards the worst case).



No, it's not - we know the ballpark value. See below.



No, it's not.



Also, see (I've posted these before):

Covid-19: Global summary

This is something that epidemiologists can figure out...

Of course it's malleable. And of course it depends on the particular country/region/group in question. That's why I was asking whether you thought masks would bring it to 1.
That paper says it's an estimate and puts it between 0.3 and 1.2, quite low.

Estimates from IHME and Imperial College were too high.

Yes, masks would lower the R0 for sure. It captures droplets which contain viruses. No it doesn't work 100% but anything is better than nothing; and of course it depends highly on the quality of the mask.
Sneezing into your shirt would help it alot too. I have not heard a single person mention it. Only me. (I think outside the box.) Sneeze downward, cover mouth/nose with your shirt collar, sneeze down into your chest/belly area. Yeah it's nasty but it contains the droplets. This should be default behavior. Otherwise you are putting your biohazard into the air. Human fluids. In medical setting they treat saliva sample similar to urine/blood/ samples. They contain it, and handle with gloves. Spraying mucus and saliva into the air is like spraying urine and blood into the air. Should be illegal.

Assume you are talking about Calif CV update today. Yes I immediately thought the same thing. So guess every business will have a temperature greeter before you can enter? I actually found today’s plan a disappointment. Don’t know what I was expecting but for an hour just expected something else. Everything said was I think pretty much expected steps so nothing really new. I thought a comprehensive plan with details was going to be laid out.

i was hoping I guess for some specific industries to get some mention. Not just Tesla but the PG&E shutdowns that undoubtedly happening come late summer/fall. Are they even thinking that far ahead? They should as pretty much everyone seems to think CV will be active in the fall.

I would hope all restaurant workers are doing that now as they prepare takeout food. In reading all the stories of meat processing shutdowns due to “positive” workers I have to wonder if the meat processed is contaminated. Need some transparency on this too.
 
Are you wanting to continue the shelter in place order, then? A little confused about what you're advocating here. Stay home, stay healthy, I suppose! But you seemed to be advocating for the opposite earlier. I guess you've changed your mind? I did not realize I was so convincing.
No, We should get back to work, but do mitigation, a new normal. Isolate the at-risk and the sick only. And make everyone exercise to get healthier.
 
It spread quickly after they forced everyone into boxes.

What? All the evidence from NY shows exactly the opposite. It was spreading fastest prior to the "New York Pause." Just look at the daily cases (as a %) and the daily net hospitalizations! It looks like a fairly constant flow of cases into the hospital currently, but hopefully we'll start seeing reductions in hospitalizations soon (which would indicate R0 less than 1). Hopefully the flattening isn't just due to the lack of tests (that certainly could be contributing to making us look like we're doing better than we actually are...but positivity is declining slightly at least).

We should get back to work, but do mitigation, a new normal.

So go back to R0 at 3, less whatever the improvement we get from face masks? Not sure that will work. Not sure specifically what you mean by mitigation.

Essentially what we should do - rank every scenario by transmitability. If low transmit, then resume. High transmit can stay closed or must enact mitigation.
Low transmit would be most outdoor activities, or anything where people can stay spaced out and good ventilation.
High transmit would be where people are close together and poor ventilation.
 
My understanding was that they screened every single pregnant woman who came to the hospital for delivery. So it was not random for the entire population, but it was better than most covid-19 testing which tends to focus on symptomatic people or is skewed in other ways.

I like to be data-driven. Is there a better study for New York City?
Pregnant women are not typical of overall population.

No studies - because nobody is doing random population checks in NY. Only thing we can do is look at deaths - and back-calculate everything based on numbers from other places. Since, even in other places IFR is hotly contested (since we are still in the initial phase of the pandemic) - you can only get a wide range for the infected. IFR could be anywhere from 0.3% to 3% - we get the infected rate of 1.8% to 18% for NY. If you take the middle - you are around 10%.

No, it spread at the same ~ exponential rate as before SAH, and then dropped off after ~ two incubation periods as would be predicted from a SAH mandate that is effective; and cannot be explained by the levels of herd-ish immunity you subscribe to.

You opinions are your own, but please accept facts and math.

I'm basing it on this: IHME | COVID-19 Projections
Look up New York
 
That's more than a stretch it's just made up s*** again.

Show me a single responsibly collected responsibly sampled not cherry-picked antibody IGG based epidemiology showing anything like that.
You're guessing 10%, I'm guessing 30-60%. How is one more "making s*** up" than the other? Everyone is guessing because no one has done any random testing.

There are 202k "confirmed cases" in NYC and 10,834 deaths. That's with hospitals refusing to test asymptomatic, mildly symptomatic, or moderately symptomatic patients. I think it's fair to say that methodology is going to count maybe 10% of total actual infections at best, I would wager it's actually lower than 5%. These are fairly rational assumptions supported by the few semi-random test groups we've seen and put us in a ballpark of 2.7M infections for NYC and a mortality rate around 0.4%.

Obviously a significant number of patients will still die in the coming week, but I think the numbers above are a conservative estimate. I still think we'll see an overall IFR under 0.2% if we god-forbid ever test a wide swath of America. I think this virus spreads like mad, but isn't too terribly deadly relative to what Rene Russo contracted in Outbreak.

IFR could be anywhere from 0.3% to 3% - we get the infected rate of 1.8% to 18% for NY. If you take the middle - you are around 10%.

Oxford Center for Evidence-Based Medicine's most recent worldwide IFR estimate is 0.1-0.36. Global Covid-19 Case Fatality Rates - CEBM

New York State currently has 10,000 deaths -- not sure of the figure for NYC but it's not hard to get into the 30-50% infected range using the CEBM's IFR range, especially taking into account that deaths lag infections. IFR/R0 are some of the hardest things to estimate and are hotly disputed, so starting with one of them rather than primary data seems backward -- in any case it isn't how I would approach it.

Anecdotally, epidemiologists seem to be taking the hospital study pretty seriously. It's certainly not the last word and there could be something unusual about the population of women coming to that hospital, but it's the best study for NYC I've seen so personally I wouldn't dismiss it unless and until better evidence emerges.

Wrong. I haven't offered a guess. So I guess that's just some more made up s***. You can't seem to stop yourself can you? Just to clarify , I'm not that big into guessing about this s***. We have professionals who don't guess, they make calculations. Lives depend on those calculations being at least ballpark accurate and not off by orders of magnitude. I'm not entirely sure where you're going with this but it's typically part of a disinformation campaign to minimize the severity of covid-19 and to suggest that any version of shutting down the economy is stupid because A) it's not that serious or . . B) we're very close to herd immunity anyway.

Wrong, and wrong. Added to the first wrong, namely that I had offered a guess of 10% exposure in New York that makes three wrongs, or in this case 3 Strikes. So you're out. Go back to the dugout. You're benched. It's plainly evident that you just can't hit the big fastball. Or throw one either. And bean balls don't count they just give the other team a free base runner.:D:D:D
