2/1/21: Covid19 update: U.S. vs EU27

In previous posts, I covered Covid-19 updates for the last week of 2020 for:
In this post, let's take a look at the latest data for the U.S. compared to the EU27.

Weekly counts of new cases and deaths, illustrated above, suggest that:
  • Since the start of the pandemic, the U.S. has experienced three waves, against the EU27's two of the pandemic. The EU27's 2nd wave appears to have crested in week 45, while the U.S.' current wave continued to rise through week 51 of 2020. Week 52 data is hard to interpret, as it represents poorer quality of data due to the holidays season.
  • Over the last 8 weeks, US new cases exceeded those in the EU27 by 337,233.
  • The EU27's 2nd wave appears to have crested in week 48 in terms of deaths, while the U.S.' current wave continued to rise through week 51. Once again, we should ignore, for now, week 52 data.
  • Over the last 8 weeks, US new deaths continued to run below those in the EU27. On population-adjusted basis, US deaths cumulated over the last 8 weeks are 33,622 lower than those in the EU27. Over the entire pandemic period, US deaths currently exceed those in the EU27 by 69,416 on population-adjusted basis.
The last point is worth considering more closely:

  • Since the start of Wave 2 in the EU27 (Wave 3 in the U.S.), EU27 deaths per capita have been converging with those in the U.S.
  • At the start of the EU27 Wave 2, U.S. excess total deaths per capita exceeded those in the EU27 by 87%. Latest excess is 26% and it was 28% in week 51.
  • Adjusting for differences in population, U.S. excess deaths relative to the EU27 fell from the Wave 1 maximum of 103,038 to 69,389 today. 
  • Adjusting for differences in population, U.S. excess deaths relative to Europe fell from the Wave 1 maximum of 122,441 to 117,690 today. 
  • Adjusting for age differences and population size differences, the U.S. pandemic is associated with 135,343 excess deaths compared to the EU27.

Despite the big negatives, mortality rates have declined for the later waves of the pandemic in both the EU27 and the U.S.:

Note: the above chart is not adjusted for demographics differences between the U.S. and the EU27, which means that part of the amelioration in mortality rates in the U.S. relative to the EU27 is down to these differences.

Lastly, rates of change in cases and deaths, both, suggest that the pandemic Wave 2 (in the EU27) and wave 3 (in the U.S.) are still at risk of re-accelerating as new data arrives and as we intergate more accurate figures for Week 52 of 2020:

Finally, a summary table for comparatives:

The table above clearly shows the reality of the pandemic impact differences between the EU27 and the U.S. to-date. Through week 52 of 2020, the U.S. performance is consistently worse than that of the EU27 in all metrics, but one: mortality rate per 1,000 positive cases. This only difference is most likely accounted for by the factor exogenous to the pandemic policy responses in the two countries, being down primarily to younger demographics of the U.S. population.

2/1/21: Covid19 update: BRIICS

 In previous posts, I covered Covid-19 updates for the last week of 2020 for:

Cumulative data for BRIICS (Brazil, Russia, India, Indonesia, China and South Africa) shows continued steady expansion of the pandemic in total cases and deaths:

  • Currently, BRIICS account for 28.2% of all cases of Covid-19 in the world, and 25.3% of all deaths. This compares to these countries accounting for 45.3% of the world population.
  • The pandemic has been relatively benign for this group of countries. If BRIICS were ranked as a stand-alone country within the group of 40 countries with more than 250,000 cases, BRIICS would have ranked 38th worst in terms of cases per 1 million of population, 37th worst in terms of deaths per capita, and 28th in terms of deaths per case. 
  • BRIICS data, however is highly heterogeneous by country: 
    • Brazil ranks 11th worst-hit country in the world in terms of infections rate, death rate per capita and mortality rate; 
    • Russia ranks 28th;
    • India ranks 38th;
    • Indonesia 31st;
    • China is unranked (officially, the country has fever than 250,000 cases, although overall robustness of the Chinese data is highly questionable); and
    • South Africa ranks 22nd worst.
  • No BRIICS country enters the league of 22 countries most-impacted by the pandemic (defined as countries with infection rate of 4% of population and higher).

Most current summary of key stats is below:

Now, to dynamics and trends.

BRIICS weekly case numbers are on the sustained rise, once again, since the trough achieved in week 45 which marked the end of the Wave 1 and the start of Wave 2 of the pandemic:

India and Brazil are showing robust and weakly-robust declines in weekly cases, while Russia and South Africa are showing robust increases. Other BRIICS are on a weak upward trend. Put frankly, my expectation is for a rise in India cases in weeks ahead as the new wave of the pandemic starts to take hold. Brazil being in a summer season is likely to have a longer lead time into the new wave.

Rather similar dynamics are taking place in deaths counts:

One key feature of the data is, of course, the clearly unreliable data from China that skews overall picture for the BRIICS group as a whole. If China's data was running at 0.75-0.9 of the average BRIICS rates, the country would have reported over 9.26 million cases (as opposed to the officially-reported 96,292 cases) and 183,400 deaths (compared to the officially-reported 4,771 deaths). It is worth noting here that these estimates reflect BRIICS rates that include official China statistics (downward bias to the estimates). What is quite amazing is not the actual numbers themselves, but the nearly total silence on the state of the Chinese statistics in much of the Western media, despite the order of differences between China and other BRIICS. Take a look at the comparative table here:

Russian stats: scrutinized left, right and center on every op-ed and news page of all major media outlets in the West are pretty much bank-on as expected: worse than average in infection rates, worse than average in deaths per capita, roughly (statistically) below average in terms of mortality rate. Similar for India. China's data is a complete and total outlier, and yet not a peep from the mainstream news. 

2/1/21: Covid19 update: Countries with > 250K cases


In previous posts, I covered worldwide trends for Covid19 pandemic evolution ( and pandemic developments in Europe and the EU27 ( Here, let's take a look at the set of countries with more than 250,000 confirmed cases.

As of week 52 of 2020, there were 40 countries in this group, accounting for 90 percent of the world total number of cases, 92 percent of the global deaths and 64 percent of the world's population. 

Tables below provide summary statistics for these countries:

You can click on the charts to magnify them.

The same data reported by regions and continents:

And a table of summary statistics:

Some noteworthy observations from the above:

  • The U.S. is the worst performing major advanced economy when it comes to the pandemic trends: it ranks 2nd worst in the world in terms of its numbers of Covid19 cases per 1 million of population, 7th worst in the world in terms of its death rate per capita, but a reasonably-benign 25th in the world in mortality rate (deaths per positive test case). Using the three metrics mentioned, the U.S. ranks 6th worst performing country in the league of all countries with > 250,000 cases.
  • The UK ranks even worse than the U.S. The country ranks 15th worst in the world in the rate of infections (Covid19 positive tests per capita), and 5th worst in deaths per capita and deaths per positive case. Across all three metrics, the UK ranks third worst in the world.
  • Belgium ranks the worst major country in overall pandemic impact terms (cases per capita, deaths per capita and deaths per case), followed by Italy in the second place. The UK, as mentioned above ranks the third, Spain forth, Peru fifth, the US and Argentina tied in the sixth place, Hungary comes in 8th, Czechia 9th and France 10th. Thus, six out of the 10 worst hit countries in the world are EU27 members.
  • In mortality terms (deaths per 1,000 cases), Mexico is the worst-performing country with 88.42 deaths per 1,000 positive cases; followed by Iran (45.56), Peru (37.19), Italy (35.12) and the UK (30.52). Overall, only 6 countries have mortality rates > 30 per 1,000 positive tests.
  • There were 7 countries with more than 1,000 deaths per 1 million of population, and only 4 countries with infection rate of > 50,000 cases per 1 million of population.
Another summary table, showing relative contributions of each country to global cases and deaths, as well as their relative shares of total global population:

The above highlights once again the severity of the pandemic in the U.S., the UK and the EU27.

2/1/21: Covid19 update: Europe


Introducing new analysis for Europe and EU27 across the main metrics of the pandemic (see data note and coverage of worldwide trends here: All data through week 52 of 2020.

Europe is continuing to experience Wave 2 of the pandemic, while EU27 is on the abating part of the pandemic curve, albeit with some volatility to the upside, especially in weeks 49-51. The above data is yet to fully reflect the beginning of the new strand of the virus (commonly referenced to the UK as the country of origin, although this appears to be a questionable reference point).

In terms of deaths, peak of the Wave 2 of the pandemic can now be timed to week 48, although in the last two weeks of 2020 there is some evidence emerging of re-amplification to the pandemic in Europe. 

Mortality rates have moderated at the peak of the Wave 2, hitting a trough at 23 per 1,000 cases, and staying at 23-24 since week 45:
Meanwhile, death rates per capita rose in the last week of the year to 797.4 per 1 million of population in EU27, up from 592.3 a month ago, and 651.5 in the Europe, up from 482.8 a month ago.

And a summary table of comparatives:

Overall, we can now call the peak of the Wave 2 of this pandemic at weeks 45 (in terms of new cases) and week 48 (in terms of deaths). That said, we can expect re-acceleration of both trends in weeks ahead as a new contagion wave develops following the last two weeks of the 2020. 

2/1/21: Covid19 update: Worldwide numbers


Starting the new year of data analysis for Covid19 pandemic, I have re-configured the charts and my database to reflect changes in ECDC reporting from daily to weekly aggregates, as reported through Thursday each week. The result is smoother data series, allowing for clearer analysis of the key trends. The downside, of course, is the lags in data reporting.

Please, note for the future: weekly data is subject to revisions by the ECDC.

First post, Worldwide figures and trends.

As of the last week of 2020, worldwide cases of positive tests have reached 80,177,400, with seventh consecutive week of above 4 million new cases reported on a weekly basis. The last week of the year data is subject to future revisions and reflects low accuracy of reporting due to holidays. Nonetheless, the pandemic shows no signs of de-acceleration globally in both cases and deaths.

As pointed out in the chart above, it is too early to call the peak of the Wave 3 of the pandemic, yet. Excluding the last week of the year, prior three weeks saw re-acceleration of the trend in new cases. Week 51 of 2020 saw the highest number of new cases on record at 4,534,601. 

Cumulated number of Covid19 related deaths reached 1,767,037 at the end of 2020, with week 52 marking the fifth consecutive week of > 70,000 new deaths per week. Week 51 marked the highest number of weekly deaths recorded to-date at 79,708. Again, given the nature of the data reporting during the last week of the year, it is too early to call the peak of the Wave 3 of the pandemic.

The mortality rate, measured as reported deaths per 1,000 cases continues to decline, but remains well above 20 deaths per 1,000 cases. The data is not, yet, reflective of the new (UK-originated) strand of the virus.

A summary table of the recent trends:

Based on monthly trends (4 weeks averages), the pandemic is showing no signs of abating in Africa, America (driven by the USA) and BRIICS, with signs of moderation off-the-peak in other parts of the world. In deaths, only Asia and Oceania are showing encouraging signs of the pandemic abating. 

Once again, even the tentative and weak signs of improvement in the pandemic dynamics mentioned above are subject to a lot of uncertainty, as the data covers the last week of 2020 and the Christmas period, both most likely contributing to underestimation of the pandemic severity.

Stay tuned for more analysis of the data.
