Mystics & Statistics

Coronavirus and the big seven

Not quite done blogging about the Coronavirus yet, as it is not quite done with us…yet.

The seven countries with the highest number of reported cases is the United States and six European Countries. These account for five of the ten richest countries in the world. They are shown below in order of number of cases (as of 9:33:26):

First is the United States (population 330 million) with 1,229K cases and over 73K deaths. This graph is of the number of cases over time, as are the rest.

Next is Spain (47 million) with 220K cases and 26K deaths.

Third on the list is Italy (60 million) with 214K cases and almost 30K deaths.

Fourth on the list is the United Kingdom (68 million) with 202K cases and over 30K deaths. The UK has clearly boggled their response worse than any other country on this listing, with the highest numbers of cases per capita and deaths per capita. This is from an island nation that had warning after Italy and Spain were struck with the virus.

Fifth is Russia (147 million) with 177K cases but only 1,625 deaths. This last figure is may be questionable. Right now their mortality rate is 0.92%.

Sixth is France (67 million) with 174K cases and 26K deaths.

Then there is Germany (83 million) with 168K cases and only 7,277 deaths. This is a morality rate of 4.33%, which is still high. Germany has certainly does the best job of all these countries in containing the virus. This is a country that is densely populated and mostly land borders. Their death figures are probably underreported due to their definitions of what constitutes a death due to coronavirus as opposed to other causes.

Also of note, are three other “western” countries: Canada, Netherlands and Belgium:

Canada (38 million) has 65K cases and only 4,366 deaths. Compared to the United States, it has 13% of the population, 5% of the cases and 6% of the deaths. Basically per capita, it infection and mortality rate is half compared to the United. U.S. mortality rate is 5.97%, strongly indicated that there are a lot more cases out there than we have not tested for. Canada’s mortality rate 6.75%, which means that they appear to have the same problem.

There is Belgium (11.5 million) with 51K cases and 8,415 deaths. This is more deaths than reported for Germany and the highest number of deaths per capita among these ten countries. Part of the reason may be again reporting, with Belgium claiming to be very “honest” in their reporting. In the end, people are going to have to look at “excess deaths” since the beginning of this year to get a proper feel of what the real comparative death counts are.

Finally, there is the Netherlands (17.5 million) has 42K case and 5,305 deaths.

It does appear like Spain, Italy, France, Germany, Belgium and Holland are bringing the virus under control. Clearly the United States, United Kingdom, Russia and Canada have not.

 

Coronavirus in the DC area – update 5

As I live and work in Northern Virginia, just a few miles outside of Washington, DC, the local situation is of interest to me, as I suspect it is to a few other readers. I will be maintaining these updates on Wednesdays for a while. Again, all the data is from the Johns Hopkin’s website (which I gather is also maintained in the DC area), as of 11:32:28 AM: Johns Hopkins CSSE

The DC area is rather sprawling, with over 5 million people scattered across DC, Virginia and Maryland. Let me list the presence of virus by location. I list the number of cases from last week followed by the number of cases this week and then the current number of reported deaths. Population is the 2018 estimate from Wikipedia:

……………………….….Population…last week…this week…Deaths

Washington D.C…………..702,445…..4,106……5,322….…..264

Arlington, VA…………..…..237,521….…912……1,169………..49

Alexandria VA………….…160,530………653………983…….…26

Fairfax County, VA……..1,150,795……3,448……4,834………201

Falls Church, VA……..…….14,772……….26………..36………….4

Fairfax City, VA……..………24,574……….27……….33…………2

Loudoun County, VA………406,850……..727………998……….24

Prince Williams C., VA….…468,011……1,449……2,223………33

Manassas…………………….41,641……..175………289……….1

Manassas Park………….…..17,307………..53……….96…….….2

Stafford Country, VA………149,960………221………308………..2

Fredericksburg, VA…….…..29,144……..….27……….45………..0

Montgomery C., MD….…1,052,567….…4,152……5,790..….333

Prince Georges C., MD….909,308………5,738……8,135…….311

Total……….…….…….…5,365,425……21,714…..30,261….1,252

 

The number of cases was doubling at every locale each week for the first three weeks I was tracking this. Week before last it only went by a little more than half (actually 58%). Last week it went up by half (actually 50%) and this week is went up less than half (actually 39%). So, a positive downward trend. although painfully slow.

The Mortality Rate for the area is 4.14%, which is high. It either means lots of vulnerable people, or the number of cases of infection are being significantly underreported. The population known to be infected is 0.56%. or one confirmed case for every 177 people. It may be that around 2% of the area has been infected.

From my observations, most people are doing a reasonable job of self isolating. Probably easier to do in this more spread out suburban area than in some cities. They do say that this area will become one of the next hotspots, but because it is spread out and primarily suburban, I don’t think it will be anything like New York. The fact that the rate of spread has been declining for three weeks is a positive sign.

The Washington DC statistic area according to some also includes Warren, Clarke, Fauquier, and Spotsylvania Counties in Virginia, Jefferson County in West Virginia, Frederick, Howard, Charles and Calvert Counties in Maryland. I rarely go to these places. Of interest to me is Albemarle County, VA with 110 confirmed cases (81 last week) and 4 deaths, and Charlottesville, VA which has 64 confirmed cases (51 last week) and 2 deaths. Montgomery County, VA has 61 cases (54 last week) and 1 death. These two areas are the home of UVA and Virginia Tech, two large universities located in a more rural environment.

Coronavirus in the DC area – update 4

The number of cases was doubling at every locale each week for the previous three weeks. Last week it only went up by half (actually 58%). This week is went up by half (actually 50%). So, this is a more positive trend.

The Mortality Rate for the area is 4.10%, which is high. It either means lots of vulnerable people, or the number of cases of infection are being significantly underreported. The population known to be infected is 0.40%. or one confirmed case for every 247 people. Probably over 1% of the area has been infected.

From my observations, most people are doing a reasonable job of self isolating. Probably easier to do in this more spread out suburban area than in some cities. They do say that this area will become one of the next hotspots, but because it is spread out and primarily suburban, I don’t think it will be anything like New York.

Some National Coronavirus Graphs – update 3

I may continue updating this post for a while. This basically addresses the question of when is the virus mitigated, or even better when it is contained, and eventually when should restrictions be relaxed. So we look at South Korea compared to the three worst plagued countries in the world. We then look at three other countries in East Asia that were near China and had to deal with the virus sooner than most. We then look at a few other countries that appear to getting the virus under control. I think there is considerable value here in comparing results across several countries. All these are simple graphs pulled from the Johns Hopkins CSSE website as of 8:31:22 AM: Johns Hopkins CSSE

Here is the graph for the number of cases in South Korea (10,702 reported cases, only 89 more case than reported around this same time last week):

This is good. This looks like a country that now has the situation under control. Note how long it took (time is on the x-axis).

In comparison, here are the graphs for the United States (842,624 reported cases), Spain (213,024 reported cases) and Italy (187,327 reported cases). It looks like Spain and Italy are reaching their deflection point:

In contrast here are the graphs for three other East Asian nations, Japan (11,950 cases), Taiwan (427 cases) and Vietnam (268 cases, the same as last week). Not sure why Japan does not have the virus under control like South Korea does. This would be worth looking into.

And here is China (83,878 reported cases), although there is still some concern about the accuracy of their statistics:

Finally, let me add the Austria (15,002 reported cases), Norway (7,338 reported cases), Australia (6,547 reported cases and only 85 new cases since last week), the Czech Republic (7,136 reported cases), Iceland (1,785 reported cases and only 58 new cases since last week) and New Zealand (1,451 reported cases and only 50 new cases since last week) to this collection of graphs as it appears that they are now reaching their inflection point and some have started leveling off:

Finally, there is Germany, which has the fifth highest number of reported cases (at 150,773). They also appear to be bringing this under control.

And then there is Singapore. Last week it had 3,614 reported cases. Now it has 11,178 reported cases. It appears that they have lost control of the situation again.

Coronavirus in the DC area – update 3

As I live and work in Northern Virginia, just a few miles outside of Washington, DC, the local situation is of interest to me, as I suspect it is to a few other readers. I will be maintaining these updates on Wednesdays for a while. Again, all the data is from the Johns Hopkin’s website (which I gather is also maintained in the DC area), as of 8:39:28 AM: Johns Hopkins CSSE

The DC area is rather sprawling, with over 5 million people scattered across DC, Virginia and Maryland. Let me list the presence of virus by location. I list the number of cases from the post three weeks ago, two weeks ago, last week’s post followed by the number of cases this week. Population is the 2018 estimate from Wikipedia:

……………………….….Population…..Week 3…Week 2…Week 1….Week 0…Deaths

Washington D.C…………..702,445……..507…….1,211……2,058… 3,098……..112

Arlington, VA…………..…..237,521…….104……….237………401……..625..…….22

Total……….…….…….…5,365,425….…1,941……..4,499……9,178……14,467……422

 

The number of cases appeared to be doubling at every locale each week for the last three weeks. This week, it only went up by half (actually 58%). So, this is a more positive trend. There were 23 deaths recorded three weeks ago, 76 two weeks ago, 222 last week and 422 this week.

The Mortality Rate for the area is 2.92%. The population known to be infected is 0.27%. or one confirmed case for every 371 people. As I suspect the real morality rate is 1% or lower, then probably about 1% of the area is infected.

From my observations, most people are doing a reasonable job of self isolating. Probably easier to do in this more spread out suburban area than in some cities. They do say that this area will become one of the next hotspots, but because it is spread out and primarily suburban, I don’t think it will be anything like New York. The fact that the rate of spread is already declining is a positive sign.

The Washington DC statistic area according to some also includes Warren, Clarke, Fauquier, and Spotsylvania Counties in Virginia, Jefferson County in West Virginia, Frederick, Howard, Charles and Calvert Counties in Maryland. I rarely go to these places. Of interest to me is Albemarle County, VA with 66 confirmed cases (50 last week) and Charlottesville, VA which has 41 confirmed cases (36 last week) and 1 death. Montgomery County, VA has 48 cases (33 last week). These two areas are the home of UVA and Virginia Tech, two large universities located in a more rural environment.

Coronavius Mortality Rates update 15

This is my last update of this post for a while. My first post on Mortality Rates was on 27 February. At that time there was 4,051 cases of Coronavirus outside of China and only 66 deaths outside of China. It is here:

Mortality Rates of the Coronavirus by Country

I am looking at shifting away from Coronavirus posts and focusing more time on defense affairs and analysis of military history.

The number of cases continue to increase,  as sadly are the number of deaths, and so is the mortality rate. In countries that previously had low mortality rates, like Germany, they have now risen to above 1% and keep rising. Germany is now at 3.31%. Now there still some people arguing that the actual mortality rate from Coronavirus is around 0.5%. There was an article recently that looked at antibody testing of Coronavirus, and discovered that 15% of the population in one German town had the virus, even though only 2% were reported as having the virus. The article is here: https://spectator.us/covid-antibody-test-german-town-shows-15-percent-infection-rate/

Now….this was a random sample of 1,000 residents, so it could just be wrong (90% confidence does mean that the data is wrong 10% of the time). And of course, it is one small town in one nation.  It does produce an infection mortality rate of 0.37%.

China continues to report very few new cases. I gather they are starting to relax their restrictions. What will happen now? If the virus is truly defeated and contained, then this should not be an issue. China has had 83,853 cases of which 77,799 recovered and 4,636 have died. If these figures are correct, this means that there are only 1,418 active cases left in China. In contrast, the United States has staggering 788,110 cases with only 73,533 recovered and a depressing 42,458 deaths. We are now 32% of the world’s reported cases and 25% of the world’s reported deaths. We are 4% of the world’s population.

Data is from Johns Hopkins CSSE 4/21/20 as of 9:38.33 AM EST. It is here: Johns Hopkins CSSE

A few more observations:

  1. The actual mortality rate is a big issue if one is going to do any estimate of potential impact (population * percent infected * mortality rate and modified by improvements in care and developments of vaccines). I have been thinking about post about this at some point…but…
    1. Do I do an estimate based upon a rate of 0.5%, 1%, 1.5% or 2%? Makes a big difference.
    2. Needless to say, the figure of 0.5% would be better. If one does estimates based upon a 1% mortality rate, the numbers are kind of scary.
  2. Countries with high mortality rate obviously have a lot more cases than they are reporting.

U.S.S. Theodore Roosevelt correction

Testing on the USS Theodore Roosevelt

I stated in the previous post on this subject that “They probably picked up the virus around 9 March while making a port call in Da Nang, Vietnam.” According to this article, this may not be the case: https://news.yahoo.com/navy-believes-delivery-flights-not-205814720.html

According to this article, they might have picked up the virus due to delivery flights made to the carrier, not from Vietnam. The navy officials say they have been unable to make a definitive link between the Vietnam port call and the cases that have occurred on the ship. The Carrier onboard deliveries (COD) flights would have originated from the Philippines or Japan.

Some National Coronavirus Graphs – update 2

Updating my posts for the last two weeks. This basically addresses the question of when is the virus mitigated, or even better when it is contained, and eventually when should restrictions be relaxed. So we look at South Korea compared to the three worst plagued countries in the world. We then look at three other countries in East Asia that were near China and had to deal with the virus sooner than most. We then look at a few other countries that appear to getting the virus under control. I think there is considerable value here in comparing results across several countries. All these are simple graphs pulled from the Johns Hopkins CSSE website as of 10:36:00 AM: Johns Hopkins CSSE

Here is the graph for the number of cases in South Korea (10,613 reported cases):

In comparison, here are the graphs for the United States (640,014 reported cases), Spain (182,816 reported cases) and Italy (165,155 reported cases). It looks like Spain and Italy are reaching their deflection point:

In contrast here are the graphs for three other East Asian nations, Japan, Taiwan and Vietnam. Note that they have fewer reported cases, 8,626, 395, 268 respectively:

And here is China (83,402 reported cases), although there is still some concern about the accuracy of their statistics:

Finally, let me add the Austria (14,451 reported cases), Norway (6,798 reported cases), Australia (6,462 reported cases), the Czech Republic (6,303 reported cases), Singapore (3,614 reported cases), Iceland (1,727 reported cases) and New Zealand (1,401 reported cases) to this collection of graphs as it appears that they are now reaching their inflection point and some have started leveling off:

There are other people publishing similar graphs. For example: https://www.cnn.com/2020/04/16/world/coronavirus-response-lessons-learned-intl/index.html

 

Coronavirus in the DC area – update 2

As I live and work in Northern Virginia, just a few miles outside of Washington, DC, the local situation is of interest to me, as I suspect it is to a few other readers. Again, all the data is from the Johns Hopkin’s website (which I gather is also maintained in the DC area), as of 7:25:19 AM: Johns Hopkins CSSE

The DC area is rather sprawling, with over 5 million people scattered across DC, Virginia and Maryland. Let me list the presence of virus by location. I list the number of cases from the post two weeks ago, last week’s post followed by the number of cases this week. Population is the 2018 estimate from Wikipedia:

……………………………………………Previous..Last……..New

………………………..….Population….Week……Week…..Cases……….Deaths

Washington D.C…………..702,445……..507…….1,211……2,058………..67

Arlington, VA…………..…..237,521…….104…….….237…..….401………….2

Alexandria VA………….…160,530……….30…..…..126………..247………….1

Fairfax County, VA……..1,150,795……..244………532….…1,207………..20

Falls Church, VA……..…….14,772……………………………………….2

Loudoun County, VA………406,850………87….…..209…..…344……………5

Total……….…….……5,365,425..…1,941…….4,499…..9,178……..222

 

The number of cases appears to be doubling at every locale each week. This is not a good trend. Do not know if that is because of more spreading or better testing. There were 23 deaths recorded the week before last, last week it was 76, now it is 222.

The Mortality Rate for the area is 2.42% up from 1.69% last week and 1.18% the previous week. The population known to be infect is 0.17%. or one confirmed case for every 585 people. From my observations, most people are doing a reasonable job of self isolating. Probably easier to do in this more spread out suburban area than in some cities. They do say that this area will become one of the next hotspots, but because it is spread out and primarily suburban, I don’t think it will be anything like New York. Still, right now, the number of cases are doubling each week.

The Washington DC statistic area according to some also includes Warren, Clarke, Fauquier, and Spotsylvania Counties in Virginia, Jefferson County in West Virginia, Frederick, Howard, Charles and Calvert Counties in Maryland. I rarely go to these places. But of interest to me is Albemarle County, VA with 50 confirmed cases and Charlottesville, VA which has 36 confirmed cases and 1 death. Montgomery County, VA has 33 cases.

Reality sets in for Russia

Sorry, but another coronavirus post. This is a follow-up to our post a month ago:

What about the Coronavirus and Russia?

Needless to way, with over 21,000 cases now reported in Russia and over 170 deaths (which are probably under-reported), Russia is very much part of the pandemic now. Chart of number of cases as of 4/14/20:
