Which I promise, China is not.
@Parallax yes
@Parallax yes
@Parallax , US government is actually boosting testing, so expect cases to skyrocket. China is not even testing which is why their cases are plummeting. Do to the transmission rate the US is most likely already near a million infected, which means the fatality rate is far less than the flu.

The question of "when does this end" "when do we see the light at the end of the tunnel" is huge to me right now. Thank you for offering a way to look at it that might offer signals for the questions I have.
That question is huge to everyone.
It's not going to end, it's the new 9/11, get used to seasonal lockdowns and shop stock shortages.
90 days until the entire world is infected at the current growth rate, which is only about 13% now, worldwide, as opposed to 30% a few weeks ago.
The more efforts we make to stop the spread the longer it will last, unless we can slow it to the point of stopping, which seems unlikely on a world scale.
I posted this as a standalone comment, but it pretty much exactly answers your question so I figured I'd paste it here too:
If you want a better way to generate basic "when does this end" predictions, you should plot a quadratic regression to your plot of y' vs y. Because we expect the growth to be fairly logistic this plot will actually be quadratic and not linear. This allows us to fit a quadratic regression to the data of the form (ax^2 +bx +c) from which we can get values and errors for a and b. We can then uses the values to find the peak of this quadratic (-b/2a) which corresponds to the number of cases when we are halfway to the peak of the disease. By properly propagating the error in the values of a and b, we then get a new interval for the approximate number of cases which we expect to see at the peak of the disease (lets call this value k for now). Then an exponential regression can be fit to the raw case data of the form (ce^(dx)) so that values and standard errors for c and d can be found. We can then solve for x as a function of c,d and k and we see that x = (2/d)ln(k/2c). Finally, propagating the error once again we're left with an interval representing the day we'll most likely hit the carrying capacity of the disease.
Doing this with the data available back in March 15th it was predicted that the peak would occur somewhere between April 17th and April 26th. But now with the current data this interval has shifted to May 5 - May 10th as of the currently available data today (these are just the numbers for the US btw, but using data from another country of interest or the global population can easily let you make the same predictions for these other populations).
On this channel any good news get deleted, it's all Doom and Gloom here.
This is EXACTLY the thing that I feel I’ve been missing in my obsessive news and stat consumption.
@Bob Smith It's entirely possible, even likely, that China is lying about infection statistics, but that doesn't mean we can't still use the data from other countries to inform our decisions. Dismissing a pandemic as "fake news" is dangerous and puts not only yourself, but everyone else at risk
Yeah, since most news organizations just pick the charts that appear most alarming / worse politically for those they don't agree with.
You need to remember, when looking at this, you're seeing China as one of the countries who are "beating corona". But they are blatantly lying, and any research into this, and videos about WHO doctors backing china on political issues, so they have access to where it started, shows this even more.
South Korea, I havent done research into it, on the surface seems like the truth. But it could be lies as well.
Not to mention all the countries lying and twisting the numbers. The UK for example, doesnt report deaths that happen outside of hospitals as Corona related. Russia is refusing to acknowledge that they're hit and has a spike in 'pneumonia' cases, Turkey was also ignoring it and pretending they had no cases, even going as far as to advertise their country online still. I mean the only way you can trust is North Korea cos their cases they solve by executing when they "escape from quarantine". This pandemic has just shown how fucked the world is, no one can tell the truth. Not even about something as serious and life threatening as this.
And lastly, countries aren't able to report their numbers rn, because of the over burdened health cares and the testing of essential people only in the UK for example.
Better way to gage how bad it is, is to look at the critical/serious tab and apply this to MPs video, as opposed to the total numbers.
@@heyday1233 they graph the number of deaths as well.
@@hazelcalderbank1556 Notice China and S Korea lines go down...controlled news. The other line going down was Diamond Princess...after all 712 on board have Corona
so, it's 2022 now... might be interesting to see a two year revisit of this topic.. how did vaccinations change the graphs visualized here? what about testing pretty much becoming routine in a lot of places? how about the rampant spread of new variants vs the spread documented here?
I was just looking at it, for some country's, it seems like they went into lockdown, and cases dropped, and then the second they got out they went back to where they would have been if they hadn't gone into it.
Others seem to have been slightly more successful, when looking at the graph with all the countries plotted, they leave the curve at about 100k total cases, and then go at a (slightly) shallower slope up, in a new main sequence (idk might be the same slope, just changed because the scales stop it being 1:1 as you move from the main sequence)
none of the country beat covid, except china with fake data, instead, most of the country choose herd immunity and live with covid, so who to blame? remember another name of covid19 is wuhan virus
Well less people are dying once they got the jab which is good thing... the bad side is governments just seem content of letting it rip overloading our hospital systems again. It's not just the people who died of covid19. It's those who died because they could not get the medical care required because the emergency ward was fully packed with covid patients.

It would be educational to go back and analyze this graph again with hindsight and another year of data points to determine what we new can learn about this approach. How did it do since a year ago.
In my view, the fact you pointed out the "caviats?" of this analysis is the biggest take away. You just educated so many people that a number is a representation of reality and is meaningless without a context. Thank you

Numbers are not the representation of the reality. In the case of China, N. Korea, Turkey, Venezuela etc, their totalitarian regimes don't like to publish the real numbers of deaths and sick people. And we now that from incidents like for example the China’s mobile carriers announced a reduction of 21 Million users for the last months. That's a very bad indication of the user's health.

@@ottomezzetti3939 I think it`s because normally you would go out and visit friends and stuff, but right now you shouldn`t, so you distance yourself socially. But yeah, there really should be another name for just not getting close on a physical level.

Numbers!!!
I've been talking about this for a month. (And it's not original with me of course.)
So far, I've never seen anything on this in the news. Instead, the news is universally hyping the exponential growth aspect of the spread. So called "experts" are pushing the impending doom rather than letting us know when to expect it to stop.
What you should look for is a decrease in the number of new cases per day. When you get a real downturn in the new cases, that means that the epidemic is about half over. Recently, new cases in Italy have decreased.
But, a the point of the decrease in new cases, the exponential growth curve is the steepest, so morons think it is getting worse instead of turning around.
The only numbers you can more or less trust are death numbers, because they are being tracked much better than the total amount of cases because of the low availability of tests in most countries. Total number of infected people now is very likely in the tens of millions if you consider the death rate (

Oz Khan yeah but trump kind of did the same thing. He downplayed the risks and ignored the problem which only accelerated the pandemic, like the Chinese at the start. Plus they did not cause this, they accelerated the process and danger of the pandemic but they did not cause it. It was going to reach the US eventually it was only a question of when.
I've watched this a few times now and it's actually a really good teaching on how to use statistics while being careful to convey what the chart does and doesn't tell us, and what we need to know about what we _don't_ know about the data, in order to use it properly.

This is brilliant, and so compelling. Hers a note to the "incomplete data: I'm from Denmark and on the 14/3 Denmark changed who should have a Corona test. Denmark went from testing everyone to only the one with severe symptoms, and hence there is a dip in your graph.
What I find very interesting, in a not-so-good-way, is that now the dailycases runs in parallel again. Frightening.
It is interesting to see how different countries react to the same situation: Switzerland has done the exact opposite, from testing only the "people at risks" with severe symptoms to testing as massively as possible (hence the scary bump in the number of cases confirmed in Switzerland). I hope we can afford to also test people who suspect they got the virus but were only mildly affected, it would certainely give interesting information on the real number of cases.
Yes, it is remarkable, even paradoxical, that this graph is significant without being reliant on uniformity of the testing (or reporting) policy of different countires.
I can tell this by comparing Italy and and S.Korea where the testing policy is completely different as indicated by the ratio of tests to positives: 4:1 in Italy, 26:1 in S.Korea.
Nonetheless the initial "main sequence" is essentially identical (until S.Korea regained control of the epidemic and drops off the main sequence).
At least the graph is insensitive to this factor so far as the policy remains constant. As You pointed out, if the testing policy worsen then it could appear as an artificial "favorable" change due to its movement relative to the historical accumulation of the total cases. Since this change of testing efficiency can also be unintended (e.g. if the epidemic saturates the testing capacity), this mimicking of "good results" is actually a very relevant concern when assessing if measures are having some positive effect.
Italy seems to slowly drop from the sequence, but what is this? Is the effect of the national lock down, or some worsening of detection and reporting? Some confidence comes from the fact that the ratio tests:positives has increased slightly (that's what You get when You increase Your capacity x13 times in 25 days but Your enemy is an exponential, that You are really happy of a slight improvement...), but it is far from settled, and it is not yet to the point that the spread is confirmed to be below its critical efficiency.
That the graph is mostly not reliant on the quality of data is a good thing, we can assess the trend without needing to make assumptions on that factor.

@@ThePinkus that's the nice thing about the double-log scale. Changes in testing methodology will just shift the line horizontally or vertically, while maintaining the overall slope. And even comparably large shifts in the absolute numbers are "dampened" by the log scales.
Could this be done with a three day avg for the y axis? I’m trying to do this for Navajo Nation. I have daily Total Covid19 case numbers and daily new cases on an excel file. I did a 3 day avg, then scatter plotted the 3 day avg to the daily total cases, so essentially the x axis is also time.

After watching a video on the number of infections, and realizing that it was not what I wanted to know, this was very beneficial.
One word: YES.
The most important thing is not where we are in absolute numbers, but rather where we are headed in relative numbers.
Finally a voice of reason among the white noise: Science.
In relative numbers most every country is headed up as in an exponential increase in infected cases. Only those regions that initiated a complete shut down early on have chance to "flatten the curve". And yet even those will likely experience a high number of cases though not necessarily an extreme number of cases.
@@michaeldeierhoi4096 flattening the curve is not binary, every precaution taken against a disease flattens the curve to some extent. Though I do agree that earlier quarantine would be FAR nore effective.

Hello! Perhaps others have already pointed this out, but what is important in your log-log plot is not that it is a straight line, but rather,
that the slope of the line is 1 for exponential growth... Other growth laws also give straight lines in this kind of plot, but with different slopes. I believe you should edit the video, as it contains important info and has a large following.

No offence, seeing and making sense of the figure and graphs is one thing, taking active measures are quite another, and here is the key point - Hongkongers and Taiwanese, both closest to China geographically and commercially were supposed to be most affected, and yet they were far better than the Europeans and Americans, because both do the same thing --> wear surgical masks whenever you are among the crowd and do not trust China. The case figures in HK and TW will show you whether this is true.
Washing hands are necessary, but for WHO to stress this is no different from making a statement of discovering that your mother is a woman. WEAR THE MASKS!
Never heard about your “wave theorem”, but yes the virus may come back.........in another kind of virus. Newest scientist research are try to find a “general vaccine” to solve groups of virus in one vaccine but this is still far away to go. There some fact about your questions why China don’t curfew and lockdown each province, in fact they did. I know this because my parents is currently in China and she told me people are not allowed to travel unless they have “health card”, country side or community are not allowed any entry even traveler have the health card, so that means my father can’t going to her own house just because he had been coming to other provinces.

This looks so amazing and tells a lot about the story. Thank you!
I want to make an analysis like this for my Country (Costa Rica) but we have few cases per day(147 in a day is the biggest one) do you recomend to use a log scale too? Or do I use the total number?
USA on the graph:
*I am speed.*
The countries that are growing the fastest are those that are doing the most testing, if you don't test anyone it would look like you have no cases when in reality you would just be ignorant to the truth.
This was one reason the UK government restricted testing to include only those already showing symptoms (and even then not everyone is being tested just those likely to survive) to artificially lower the numbers.
In my opinion everyone should be tested so that those who test as post infection can be studied to establish what the long term immunity and infection rates are likely to be, by taking regular follow up samples and possibly volunteers re exposing themselves for medical research.
And those that show no infection can take the precautions necessary, no point everyone staying home of half of you have already had the virus.
Without testing their will be countless people convinced they are immune when in fact they had a regular flu or cold, putting themselves and others in danger out of ignorance.

Thank you for the inspiring video. I have been wondering about how to detect new outbreaks. Following a similar approach, we could count new cases as a number of total cases after "the" end of the last outbreak, but that would require to identify the end of the last outbreak. Plotting the total count on a linear-x, logarithm-y-axis may however seem to be a better approach but I fail to see why it shoud be.

Doesn't the graph look similar because the logarithmic scale is too big to measure(comparative minor) deviations? It's like differentiating 2 stars in the sky, despite being very different in size they would look more or less similar, like a dot. Kindly enlighten.

you have to understand a bit about calculus and stats to understand this video.
He is full of it. He is definitely plotting against time. That is the only way he can get those charts. The implication is the total number of cases increases with time. He just superimposes it on the graph as a line. The time factor is just not presented as a consistent linear or log scale. What it really doesn't show in the graph is how rapidly the disease is progressing. A disease that reaches 100K infection in one week vs one year looks like the same graph on his chart since it only counts the total number of cases.
@@ahndeux But his point was do not plot AGAINST time lol which in my understanding means not putting the class intervals representing time on the x axis, right?
@@ahndeux u mislook the y-axis, which is the cumulative new case in past week.
So 100k in 1 week vs 1 year definitely will not be the same

I don’t know why this gives you calm. This graph shows that only 2 countries (South Korea and China) have SLOWED the spread (not even stopped) and that every other country still has rapid exponential spread of the virus
@@AR-ob7nl That and China is not being completely honest about their death toll numbers
@@AR-ob7nl This can't be said enough. Why in the world would this give anyone peace of mind? The answer is that despite how informative this video is, it's still over the heads of common lay people.

After returning from China to the USA my boyfriend had “the worst flu of his life” with high fever, coughing, malaise that tapered off after a couple weeks. CDC has nothing to say when called. Now i’m midway through something eerily similar. Can’t get a hospital, can’t find a drive through test, CDC is overwhelmed no one has counted our data.
And they call the numbers in China fake...
Gotta love seeing the noble land of Diamond Princess on all these
Jack Davey IKR LMAO
Do you know what diamond Princess actually is ? It not quite as noble as it is a tragic case study of the spread of the virus in a closed environment
Love how Denmark, Sweden and Norway, each do a little dip in the chart, diverging from the rest...but then continue upward.
Being from Denmark myself, I can confirm how there was a public announcement, causing a bit of a scare, that led to an initial panic, followed by a period of nation-wide isolation (as desired). Shopping was SUCH a delight in this time. You'd go into a store and there'd be 2~3 other people, allowing me to get my shopping done in seconds.
However, now that a few weeks have passed, people got _"used to"_ or I might even say... _"BORED"_ of the Covid-19 spread and loosened up way too much... Now that I go shopping, the stores a crammed as usual. Old folks, who are ill advised to be leaving the safety of their homes in these times, pushing carts around at 1 meter per minute. Couples, bringing ALL their kids, to clog up the candy, or dairy-isle, to bicker over what flavor yogurt to get and whatnot... That's likely why, the growth has picked up again, in Scandinavia.
People got way too relaxed, way too soon, all at the same time, to continue as they've always had and thus, the spread picks up the pace again. 😷
Well, Sweden just test the people in hospitals/the one in the risk group, therefor will we only have a lwoer amount of detected cases aswell. Then it's possible to say " we have it under control" but in reality the goverment is just putting their head in the sand.
But today they announced they will start testing more people other than ppl in hospitals & risk group, so maybe it's just gonna come as a huuuge spike now as detected cases in sweden.
The issue is the death increase you see now is from people that got infected 2-3 weeks ago. It takes about a week to acquire symptoms and than it gets more serious to a point where you're forced oxygen and when it gets real bad you lose 80% of your lung capacity and die eventually. So A LOT more people will get infected when they're packed in supermarkets.
The Swedish government isn’t really caring about our people, people in Lomma are going out side to restaurants. The only thing my school did to prevent corona spreading was to let one class after another lot to go inside to get food

Thanks. I was just telling a friend that many people have trouble comprehending exponential growth. This does a great job of explaning that.
That's a start, but this is more likely to follow a logistics curve where it starts out exponential and then slows down in a similar way as the number of potential hosts and resources decrease.
en.wikipedia.org/wiki/Logistic_function It shows up a lot in things like this and word of mouth campaign as you start slow, it gets extremely fast, and then it tails off at the end.
How can people work with this data when it's inaccurate and full of lies? Especially China. Are people that gullible?
can u please say which animation software did u usesd for ur video?
Very good video (as usual).
Always have a good understanding of the problem!
Really interesting point about how more infections --> more testing ---> more "cases". That helps explain the absolute explosion in the growth rate when the virus starts to become worrying enough that mass testing happens
Only if you're trying to hold onto your narrative that its all a hoax and you're trying to insulate yourself from being really really wrong in your predictions a week or so ago.
Mass testing at a national level did not occur, the capacity for this is non existent. Essentially all testing are risk-assessment based. You can roughly estimate the criteria of admission to test by the ratio of tests done to positive cases. This gives the mean risk of resulting positive for the population that was tested.
With 26:1 in S.Korea I estimate that the policy tested people with a mean of 5% risk (I am assuming 70% sensitivity, and the estimation is blatantly rough).
With 2,5:1 in Lombardy the policy tested people with more than a 50% risk of being positive.
This indicates a lot about how proactive is the effort of identifying "hidden" cases.
Or rather (roughly speaking) in S.Korea they were looking for hidden cases, in Lombardy just for confirmation of the already likely diagnosis.
This indicates/rates how countries manage the epidemic. No surprise that Italy was forced into a national lock down.
The ratio between infected and deaths are invers to what you are telling here.
500 people show up to test....10 have it in the line...now 100+ will have it in 2-14 days. Rinse and repeat. Testing doesn't cure anything.

Pepper 403 he’s got a higher approval rating now than ever before (according to the accumulator of all popularity surveys on FiveThirtyEight). People are believing him. Our country literally believes a month’s rent and billions in bailouts to the companies that spread this shit around will cure both the virus and it’s associated economic collapse. Why? Because of less than a week of positive stock data fueled solely by the bailouts and thirty damage control press releases where he makes nothing but empty promises and self-hype monologues. Meanwhile the virus continues unimpeded and unemployment is absolutely exploding. We’re all fucking doomed.
@@Natibe_ He's the President during a difficult time in America. Every President has lied too. And yeah, right now he's been lying quite a bit about getting testing to everyone and etc. But that doesn't mean he's terrible. He's trying to keep the country Calm. Also, the people that believe that are idiots and are obviously not looking at stats and crap. Media is exploding the virus and honestly it's hard to choose on what to believe at this point. Ppl want to trust the President but sadly the government is a Lil corrupted. We're not all doomed though. The virus is causing unemployment yes but that in itself is not the governments fualt. And they're trying to do the best they can but honestly, anything Trump does to try to help is going to get sh*it on. And that's why I am some what defending him.
