The R0 (R naught) that Murray is talking about, is actually a factor of not only how contagious a disease is, but also, the environment that it "operates" or exists in!!
For example, a very contagious disease "loose" in a practically unoccupied countryside will have a much lower R0 than the same disease "loose" in a densely populated city that does not curtail in any way person to person contact!
So how we (as a group - all people) act (or don't) will have an impact on the spread of this disease.
It appears to me that we are now past the "contain" phase, and must now concentrate on trying to delay how fast and far it spreads to try to lower the impact on our health systems. A large "spike" in cases could be extremely detrimental as described above in Post #85.
Do you know how to apply the R0 number in terms of time?
If someone is contagious for an average of one week for example, do you multiply the known cases by the R0 number once for every week to estimate how many people may be infected in the future?
"The basic reproduction number, R0 is defined as the expected number of secondary cases produced by a single (typical) infection in a completely susceptible population. It is important to note that R0 is a dimensionless number and not a rate, which would have units of time..."
"Meet up with others? Are you nutz? They all got cooties, maybe even THE virus."
Or they may have planned well and have food .
"The US case numbers are definitely underreported because we aren’t testing very many people at all. A cynic would say that’s by design, for political purposes. I’m trying to not be that cynic, but it’s getting harder and harder."
Probably 90% of the medicines , antibiotics and test kits are made in China .
Why would they be in a hurry to supply the USA?
We have serious Flu every year, thousands die, every year. If one does not take precautions against the Flu virus, like flu shots, hand washing and general personal hygiene, why all of a sudden all the interest in a different virus with similar outcomes? I'm more worried about the Flu, more likely to catch the Flu, more likely to die from the Flu. I'm going to wash my damn hands and live my life!

I can envision our eventual death rates here in the US to be at least as high as Italy’s because we are doing basically nothing to contain it, and as a result our hospitals will be jammed to capacity. When others with critical respiratory symptoms can’t get a hospital bed, they will die.
The death rates in Wuhan were much higher than elsewhere in China because they ran out of hospital beds.
Well, if folks are dropping dead left, right and center, then I'll get on my boat with my wife and dog and head to Princess Louisa Inlet for a month. Your boat becomes your escape. And while people are dropping dead all over, I'll be looking at Chatterbox Falls, thinking... wow!
I wonder if those deaths will or should be counted as being caused by the virus? If you die from injuries sustained in a fall at home that you would have survived if there was an ICU bed available, does that get counted?
I am thinking that there are going to be some very hard triage decisions to be made in the coming weeks......
So you should. But you overlooked something I highlighted above. Yes,there are "flu shots",but there are no "covid 19 shots".We have serious Flu every year, thousands die, every year. If one does not take precautions against the Flu virus, like flu shots, hand washing and general personal hygiene, why all of a sudden all the interest in a different virus with similar outcomes?

Just wondering what the general consensus is on buying a boat during the Coronavirus event. Should I or shouldn't I? Boat is a 55ft trawler style boat in the half mill range.
As a starter, you can multiply deaths to flu by 20 times to have a Covid 19 death toll estimate
That's a low ball number. Italy is seeing a 4.3% death rate, so you could multiply flu deaths which are usually pegged somewhere around 0.1% by 43 times.
Then again, nobody on Earth has immunity to Covid 19 because our species has never seen it before, so the numbers could go vastly higher.
During the Spanish Flu of 1918 (so far, it seems to have had similar death rate and also highly contagious) 3 million died around July, 20 million more died by November, and another 7 million had died by the following April. Those are low numbers...some estimate well over 50 million died.
We're smarter now, but there are 4 times more people on the planet.
I would suggest people not get their health news from politicians!
I guess time will tell, you may be right and we may all die, I'm not buying it!
I would suggest people not get their health news from 24hr news cycle!
If you had clicked on some of the links in my posts, you'd have noticed they are mostly from scientific journals or from credible news websites....
We're not all going to die, but if we did nothing the credible low ball guesstimates I've seen is that 40% of us will get the virus, and of those, 2% will die. That equals 60 million people.
The best way we know to protect yourself is to wash your hands and to stop touching your face. Wearing a face mask no matter how ineffective it is at blocking airborne contamination is the best way to do that. You can’t touch your face with a barrier of cloth between your fingers and your skin.
Ted,
I think Murray's figures were for "world wide" as that is how the Spanish Flu is discussed, and I think you looked at US numbers. I hope none of them come true, but I do prepare for self (family) isolation and dependence. Take precautions, they are the only thing we have now, and if we wait, it could be too late to adjust later?
Don't get me wrong, I know that about 80% of cases seem to be mild, (still prefer not to experience even that), but what about the other people (20%)?
Ok, didn't catch the "in the world" part, but still over what time frame?
In the bolded part, where have the percentages been scientifically determined? I'm not aware of any area with what could be called a "Scientific Sample Size ", that has 100% been tested. They're talking maybe educated guesses. Any guess on what percentage of the people are carriers and never show symptoms?
I'm all for taking precautions, but predicting world death totals on a 3 month old virus without anything resembling scientific sampling, dosen't help.
