This post is intended to be the hub for Wolfram resources related to novel coronavirus disease COVID-19 that originated in Wuhan, China. The larger aim is to provide a forum for disseminating ways in which Wolfram technologies and coding can be utilized to shed light on the virus and pandemic. Possibilities include using the Wolfram Language for data-mining, modeling, analysis, visualizations, and so forth. Among other things, we encourage comments and feedback on these resources. Please note that this is intended for technical analysis and discussion supported by computation. Aspects outside this scope and better suited for different forums should be avoided. Thank you for your contribution!

 There is also raw data being collected here in the form of a Google Sheet. It relies on data abstracted by a human (a work study student at the University of Houston operating under my supervision) from the daily reports being produced by the World Health Organization. I attach a notebook that shows how the data can be sucked in from the Google Sheet and turned into a Wolfram Language Dataset. From there, I run a few basic queries.

 I just wanted to note for anyone who might be interested that the latest release of IGraph/M from a few days ago now exposes the igraph C library's SIR modelling functionality. It is fairly simple at the moment. It can run several simultaneous stochastic SIR simulations on a network, and only returns the S, I, R values at each timestep (not individual node states). It can be used to study the effect of network structure on the spreading.http://szhorvat.net/mathematica/IGDocumentation/#epidemic-modelsUPDATE: I just added another example to the documentation to clarify what this functionality is good for. If you've opened the above link before, please do a hard-refresh of the page (Shift-F5 on Linux/Windows or Command-Shift-R on Mac)

 I have compiled some of the work done so far into a compact cloud dashboard: https://wolfr.am/COVID19DashboardIt is mainly built to give an overview of some information from our WDR resources, with corresponding daily updates. It is still a work in progress; I will be adding more visualizations and interactivity in the coming days. (The code is rather messy, but I'll also be publishing a cleaned-up notebook with some sample code for creating similar elements.)Aside from the visual elements, folks here might find the "Resources" tab helpful. It includes several of the Wolfram resources listed here, but also has some external resources I've seen floating around in several threads about the outbreak. I'll be continuously adding to that section as well.Feel free to comment if you think of anything you'd like to see added! (Or if you see something that isn't working--e.g. the tooltips for the world map, which I'm looking to fix.)Enjoy!

 It is very nice to see how fast Wolfram Inc is moving in gathering and curating data on the corona virus outbreak. Thank you very much!Still, for me to use, e.g. the ResourceObject["Patient Medical Data for Novel Coronavirus 2019-nCoV from Wuhan, China"]it is paramount the I can trust the data source, especially in this Age of Misinformation. You give a name and a link to a Google Sheet, but who is behind that? Which organization? How have you curated that specific data set?Best, Per Møldrup-Dalum

 In case it's not covered in data resources in OP, here is a history data source someone crawled from Ding Xiang Yuan (DXY), down to every cities of every provinces in China.COVID-19/2019-nCoV Infection Data Realtime Crawlerhttps://github.com/BlankerL/DXY-COVID-19-Crawler/blob/master/README.en.mdNote the data source is non-official. DXY, as I know it, is an online non-gov society of doctors and nurses from mainland china. Their data could be different from officially published one.

 I suspect the problem is early data collection. Iran probably does not have the resources to detect whether all exposed cases have become infected. Thus the cumulative case data will lag the actual cases until the backlog of cases in the community is discovered. The log plot of cumulative cases from the JHU data is still showing exponential growth.When quarantine measures start to work or susceptible population significantly declines, the graph should start to show growth slower than exponential. Until that happens it won't be possible to predict the end of the epidemic.

 Dear @Hee-Young, Not sure about (1), but I passed your post to our team. It’s an interesting question. I do know that people have been tested in areas with no confirmed cases. Finding out more about that could give an interesting look at the effectiveness of containment/prevention in those areas.For (2), the source data gives the region information, which is actually the mixture of AdministrativeDivision, City, County as well as Air force base location. In the latest Wolfram Data Repository (WDR) item, we have the AdministrativeDivision column as well as more specific location (which gives the city or country information). So far most of the cities are for the US but I see some Canadian cities as well so it looks like there is possibility that more city information (outside the US) will be added in the future. Also note that the dataset has GeoPosition column, which gives more details and was used to create this additional example with geo bubbles (details at WDR): Show[GeoRegionValuePlot[ Normal@ResourceData["Epidemic Data for Novel Coronavirus COVID-19"][ Select[MatchQ[Entity["Country", "UnitedStates"], #Country] &]][ GroupBy["AdministrativeDivision"], Total, #ConfirmedCases["LastValue"] &]], GeoBubbleChart[ Normal@ResourceData["Epidemic Data for Novel Coronavirus COVID-19"][ Select[MatchQ[Entity["Country", "UnitedStates"], #Country] && !

 Here are a couple of other ideas. The case data for Italy is starting to converge, so you could use the L from that and estimate that the deaths stay a relatively stable ratio to cases. That might be a big assumption for Italy where the death rate seems too high. You can also track parameter convergence--this is dramatically convincing for South Korea. Code for these functions using case data for Italy and South Korea are in the attached files as well as code to fit to the differential equation, from the first derivative of the logistic function. Rather than using interpolation to get the derivatives you could manually draw approximate ideal slope lines to the data to get an estimate for k and L from the equation for the parabola. Also when the log plot starts to show downward concavity, use only the most recent points which will be in the logistic phase. Attachments:

 I have studied the genetic sequences of COVID-19 and SARS-like viruses, using Chaos Game Representation and Z-curve methods (hyperlinks to my Community posts). Z-curves provide a fascinating visualization of genomes that helps a lot for classification and clustering. The hierarchical clustering of viruses identifies Bat coronavirus RaTG13 as the most-likely culprit of COVID-19. My results strongly support the hypothesis of a Bat origin of COVID-19. I appreciate any comment or feedback :-)
Posted 2 years ago
 Dear Vitaliy and many other experts, Is it possible to compile the data for the number of testing? So that we can get the ratio of the confirmed cases relative to those who get tested? Is it also possible to redesign the data set to include the 'City', in addition to the current geographical classification, namely, country/region and administrative region? That way, perhaps we can get more detailed information about the containment and spread of the COVID-19 inside and outside of the city? Best,

 HI.In the attached notebook, I've fitted a Logistic model to Wolfram repository data for CoV deaths from Italy through March11, with 90% confidence bands out to March 15. Since we're still in an early phase of the outbreak, the bands diverge relatively rapidly as expected.In the NLM fit, I've added a constraint to "L" based on the a-priori information that the number of deaths cannot be less than a number close to the present value. However, when I print out the ParameterConfidenceIntervalTable, the 90% CI for L is: {-3453.81, 15896.9}, with expected value 6221. I also get the warning: FittedModel::constr: The property values {ParameterConfidenceIntervalTable} assume an unconstrained model. The results for these properties may not be valid, particularly if the fitted parameters are near a constraint boundary.Now, I expect there to be a very wide interval for L given the early phase of the outbreak. But, the Confidence Intervals are not taking into account my a-priori information, and the warning explains it. It seems to me there must be a method where the CI of the fit parameters can take into account this a-priori info (in my case, L > 1200). Is this a missing feature in Mathematica?Stephen Rector Attachments:

 There has been considerable controversy in the United States (and elsewhere0 about the true incidence of COVID-19. The lack of certainty is significantly due to the difficulty in testing the entire relevant population. I've create a notebook that suggests an algebraic method for estimating the incidence in the entire population. Basically, the user inputs six facts: (1) the population of the nation in question (pop); (2) the number of tests conducted in the relevant time period (perhaps the period in which an individual may have the disease) (tested); (3) the sensitivity of the test used to detect the disease (sensitivity); (4) the specificity of the test used to detect the disease (specificity); (5) the fraction of persons with the disease who seek out testing (s1) ; and (6) the fraction of tests coming back positive (pos). We now have six equations with six unknowns, which can yield an exact solution. Comments welcome. The default values in the Manipulate are pegged to United States data and attempt to reflect approximately the last 10 days.

 Robert:Thank you so much - that was a very helpful discussion, and I will go through the other discussion thread that you linked to.The one problem with choosing to fit to an exponential model (because the outbreak is in its exponential phase), is that it eliminates L as a parameter, and I am interested in that value. Nevertheless, it's also a useful thing to have better short term estimates as you showed.If I insist that my model also produces a value for L, I must accept that the estimate of this value will be poor while the outbreak is in its exponential phase. And that makes sense. I had hoped that a constraint might add some extra information to the model, but apparently this damages the parameter estimation. I assume L estimation gets better when the phase reaches its midpoint.Thanks for your very helpful demonstration!Steve Rector

 I noticed that there is a clear correlation in case counts in the last few days between European countries. Why would this be? Does anyone know if the data is normalized or post-processed in any way that could cause this effect? Or is the effect present in the true numbers?Specifically: March 13: all European countries have a bigger than usual increase March 12: all of them have a smaller than usual increase The non-European countries in the plot (Iran, USA, Korea) don't follow this pattern Any opinions on this?I can't believe it's not some data post-processing effect. That's the only thing that makes sense. Can anyone confirm this?These countries (or even regions of the same country) are too far to influence each other directly. The pattern makes no sense in the context of weekend/weekday (why would Thursday have a smaller increase than Wednesday?) Edited for clarity.
Posted 2 years ago
 Why is this surprising? The rate of spread of the infection depends upon the virus and quarantine methods, which have been known for centuries. The virus doesn't discriminate by nationality, and all European countries should know basic epidemiology. The one day difference, could simply be Roche shipping more test kits on the same day.South Korea, the outlier, got a lucky break all their index cases belonged to a religious group that had visited Wuhan together. The cases were all known instantly and easy to isolate.
Posted 2 years ago
 I am not talking about all of them having an exponential growth (I thought this would be obvious, but next time I'll spell it out :-) ) I am talking about the fluctuations in the last few days, which are common to the European countries in the plot, but not to Iran, the US or Korea.If testing is currently limited by the manufacturing of kits, and most come from the same source, then you could be right.Another suggestion I got is that the data reporting deadline (for this particular dataset) has changed, shifting some reported cases from March 12 to March 13. This seems the most plausible to me, so far.

 In the post "An SEIR like model that fits the coronavirus infection data" https://community.wolfram.com/groups/-/m/t/1888335listed above under epidemic modeling, I discuss how to fit an SEIR-like model to the coronavirus data. I argue that there is value in doing this regardless of how good the data might be in that a good fit nevertheless allows one to understand the dynamics of an outbreak and make forecasts (how many cases, how long of an outbreak). The key to being able to find a good fit for the data is to estimate initial susceptibility correctly. I argue that the main effect of a lockdown is to lower this number drastically. In the discussions of the post I provide a thought experiment which illustrates why this is so. Susceptibility thus understood is also used to illustrate the effect of lifting containment restrictions too early. In the post there are models for several countries, including China, USA, Austria, Finland, France, Germany, Italy, Spain, and the UK. There is additional material, including a pdf document with smoothened curves of daily case tallies for several countries. I attach some pictures from the post. The models are updated on a daily basis. Please visit the post for the updates, they will not be reflected in this response. I attach a notebook with the simplest version of the model that needs to be updated but is fully functional. Attachments:

 I posted a simple model for assessing new caseloads in US cities.https://community.wolfram.com/groups/-/m/t/1945196This builds on work from a prior post that works with an estimate of the logarithmic derivative of tested-positive counts as a function of time. The extrapolation gives what amount to testable hypotheses in the sense that it predicts near-term caseloads (so in a few weeks I get to find out whether or not I completely missed the mark).Should this model turn out to have some predictive power, an important virtue is that it is remarkably simple. In addition to using a only straightforward differential equation, it requires but few hypotheses and no fitting of parameters (all values come from existing data). Models this spare on underlying requirements are always good to have. When they work, that is.

## What Is Going on in South Korea?

A country which controlled exponential spread of the virus more quickly than any other country in the world, now seems to be in a phase of linear growth of cases at about 100 per day. Linear growth should have been easy to control over several mean incubation periods. Something else must be going on. Perhaps a mutation? Persistent carrier spread with low transmissibility? Given the realities of medical testing, a significant false positive rate is another possibility, which might also explain the low death rate. Any other ideas????

Posted 2 years ago
 @Robert Rimmer, nice observation! I think it fits very well with SIR model. So maybe SIR model can explains it
Posted 2 years ago
 But that model implies an odd method of quarantine. The population of South Korea is over 50 million. The model you show takes 17000 people, presumably infected and contacts, and puts them into a camp away from the 50 million population and then lets the infection run its course. Ideally a good quarantine model should keep initially healthy people at risk away from known infected people, with the goal that many of the people at risk will not become infected because of the quarantine. With effective quarantine new cases should stop within the few incubation periods it takes to trace the contacts.
Posted 2 years ago
 This is an issue several of us have been struggling with. Enrique Garcia Moreno E., University of Helsinki uses an effective population size. I have found that the only way to get the model close to the data is to 1) use standard incidence, and 2) use an effective population size that is much smaller than the actual population. The smaller smaller effective population size is justified because the assumption of complete and rapid mixing of the population does not hold. However, I would like to find an appropriate way to model the actual mixing while retaining the full population size.A second method of reducing the effective population size is to include a quarantine compartment in equilibrium with the susceptible compartment to model the lock-down mitigation strategy used in many countries. I have not had much success with it however, most likely because the influx and efflux rates need to be time-dependent.

 The epidemiological models are useful for understanding different levels of dynamics, but it is hard to get all the rates right until the epidemic is over. Since coronavirus is assumed to be new to the human race, almost everybody should be susceptible. And since there is no treatment nor vaccination, then quarantine becomes the only effective method of control. The logistic model only requires that at some point quarantine becomes effective. At the outset, the infection can spread exponentially because almost everybody is susceptible, the exponential phase can go to complete diffusion because of easy international travel so a few hundreds of infected people can seed most of the world. Thus the only way to break the spread is effective quarantine. And the spread of quarantine methodology has to be faster than the spread of the infection. So with coronavirus now that there is effective testing to enhance quarantine, the quarantine method should halt the spread. Looking at the logistic model, early on in the epidemic there is little evidence that quarantine is working, until it fully kicks in, then control should be rapid. This is a graph I am finding useful. It is for the state of New York. The orange dots are the differences of the logarithms of the daily total cases. Thus it is a continuous growth rate. If growth were exponential it would be a horizontal line. And at the outset there is no pattern to the daily rates--they could be fit to any model, The blue dots are the course of daily rates predicted by the logistic model using all the orange dots for the fit. There is apparent convergence to the logistic model as the epidemic progresses. The default fitting method using Norm also favors the more recent points. This is a log plot of the cumulative cases in orange fit to the logistic model in blue. Since the squares of the later much higher values dominate, the early data are effectively ignored.But in this case ignoring the early data is a good thing because early on there was not adequate testing and only the most obvious cases could be discovered. Since the counts are cumulative, cases which are eventually found end up in the cumulative totals, and it only takes three points with accurate information to fit the curve.Since the quarantine effect can easily dominate, by spread of information almost instantly, quarantine could potentially break the epidemic in a maximum incubation period. For instance if a distance of six feet between each person for two weeks maximum incubation would break the transmission, then the epidemic could end in two weeks if everybody actually complied, and there were no people with carrier states.I think the solution to the epidemiological modeling is to use the logistic model which only assumes quarantine first. Once the logistic model kicks in, it should give an accurate prediction of the susceptible population, as its limiting population, L. The rate parameter, k, is at the dashed line in the first graph, and this is likely a good estimate of the maximum exponential rate of spread for the virus.

 In a very short essay, I’ve explored COVID19 fatality vs population age and income over US counties. My analysis suggests that the case-fatality ratio decreases by a factor of about 2 when the median household income goes from $30,000 to$60,000. However, it shows less sensitivity to incomes of \$60,000 or more. Additionally, the case-fatality ratio increases slightly with the median age, as expected. On the other hand, if one considers the population of 65-yrs old and over, the case-fatality ratio shows some counterintuitive features, e.g., it decreases by this population, which is not what one expected (in fact, one may expect the reserve). The visualization of median house hold income vs population of 65yrs old and over suggests that the income increases by this population, which may imply better health care services and ultimately less fatality.

 Are there data of deaths due to COVID-19 over time and age, separated by individuals' heath conditions, such as: 1. None 2. Asthma 3. Pulmonary 4. Heart and combinations thereof. Also, in view of Dr. Oz's observation that many thousands Lupus patients and others taking Hydroxychloquine, it would be very informative to determine their vulnerability to the virus collectively, or compartmentalized by other heath conditions as stated above. This granularity may add to a meaningful analysis and prognosis for a given population and enable improved measures to recommend activities at commensurate levels with respect to other associated imperatives.

 Attn: Szabolcs Horvát <--- Robert, please forward, Thanks, Sam DanielSzabolcs Horvát's case counts curves show that most countries have yet to gear up their testing and the rate of cases discovered remains steep. In contrast, the South Korea curve is flattening out, very likely due to its aggressively and extensive testing, showing that they rate of new cases is diminishing. On the other hand, the Iran and Germany curves show large case numbers, but it appears that they have many more cases to discover. Clearly all the other curves are yet to catch up...It would be more interesting, if the data existed, to plot case-naiver curves against age and prior health conditions. That is, a 3D plot with dimensions {x,y,z} = {cases, age, all underlying conditions}. Medical professionals might also be interested is specific underlying conditions, such as pulmonary hypertension, etc.
