17/4/21: COVID19: Worldwide Data

Despite the ongoing efforts to accelerate vaccinations, we can now, sadly, confirm that globally, we are in the fourth wave of the pandemic:

As reminder,  we exited Wave 3 that started Week 34, 2020, peaked in Week 1, 2021, and bottomed out in Week 7 of 2021. Since Week 8 of 2021, we are seeing growth of a new wave, Wave 4 which has now reaching the peak of Wave 3. The latest level of new infections is now second highest weekly count in the history of the pandemic, at 4,833,991 cases compared to 5,284,581 cases at the peak of Wave 3 in week 1 of 2021.

There is a two weeks lag in the dynamics of deaths counts compared to the dynamics of new cases registrations. Nonetheless, we can now confirm Wave 4 development based on weekly deaths as well as on weekly new case counts. The latest weekly death counts as of Week 14, 2021, ranks 5th highest in the history of the pandemic.

Mortality rates remain subdued, as through the Wave 3 of the pandemic. Which is the only decent news from the recent data.

A summary table by region:

In summary: the pandemic is not abating, despite significant inroads made in terms of vaccinations, especially in the advanced economies. It is a loud and clear reminder to us all that vaccinations in the advanced economies are not enough to cut global rates of infections, and every day lost to lower rates of vaccinations in the emerging economies is another day left to virus to potentially mutate and produce yet another more contagious and deadly variant.

2/4/21: COVID19: U.S. vs EU27 comparatives

US vs EU27 comparatives in the pandemic dynamics through the week 12 of 2021 are showing continued, albeit declining improvement in the relative position of the US. That said, much of the improvement is down to lags in new waves development, with the EU27 now firmly in its Wave 3 and the U.S. potentially entering Wave 4.

Based on the table and charts posted above, Europe (EU27) has now lost the plot on containing the pandemic. This takes place at the time when EU27 is botching roll out of vaccinations. On the more optimistic side, the U.S. roll out of vaccines has been relatively fast-paced, although logistics and delivery have been highly varied across different states and effectiveness can be significantly improved.

As the result, U.S. has managed to somewhat shrink the gap in terms of excess deaths from Covid19 pandemic compared to the EU27.

With more people infected, and higher vaccination rates, the U.S. is also holding a major advantage on the EU27 in terms of mortality rates per case.

Nonetheless, dynamics of the pandemic evolution are not promising: the U.S. is potentially entering a new wave of the pandemic, Wave 4, on foot of:
  • Dramatic relaxation of prior restrictions and public health measures across many states, well-ahead of vaccinations making a significant impact on infections;
  • Increased seasonal travel and social activities (primarily due to Spring Break);
  • Severely lax enforcement of Covid19 restrictions and measures during the last 3 months; and
  • Effectively free-for-all, cavalier approach to public safety by many U.S. residents.
Growth rates in both cases and deaths are quite dramatic:

If sustained, these dynamics will lead to acceleration in deaths counts in the U.S. and Europe. As things stand, the U.S. death toll from this pandemic already exceeds the combined number of combat-related deaths sustained by the U.S. is ALL wars from the mid-point of the Civil War. Put differently, Covid19 has now officially killed more Americans within one year of the pandemic as 160 years of all wars the U.S. engaged in. The U.S. excess death toll relative to the EU27, adjusting for population sizes is now at 111,789 - more than all deaths in combat since 1945. Adjusting for age differences and population sizes, U.S. excess mortality from Covid19 is 125,204 or more than total U.S. combat deaths since the start of 1945, the last year of World War 2.

Is American public health system fit for purpose? Anyone? 

2/4/21: COVID19: BRIICS

 As warned last month, BRIICS are now in a new wave of the pandemic, just like the rest of the world:

The new wave is worse than the previous one in terms of new weekly case counts and deaths. Brazil and India are leading the new cases pandemic, while Brazil leads in terms of deaths. Russia is relatively stable on deaths counts at highly elevated levels, while India death counts (highly suspicious in terms of low numbers throughout the entire 2021 so far) are now rising once again.

Table above shows summary of dynamics in current weekly cases and deaths relative to the prior 4 weeks average. 

These numbers strongly indicate that risk of pandemic will continue to spill over across the world, with no country immune to the new wave developing, until reaching 'herd immunity' levels via immunizations, assuming no adverse mutations in the virus.

1/34/21: COVID19: Most impacted countries

 Here is a set of summary tables for world's most impacted countries:

First, 17 countries with more than 7% of population tested positive:

And 16 countries with more than 0.15% of population dead:

Most are smaller in population countries. Outliers to this rule are:
  • The U.S. that enters both of the lists as the only country with population > 15 million
  • Mexico that enters the list for highest mortality countries (alongside the U.S.) - the only two countries on the list with population > 100 million
  • Spain, UK and Italy are the three countries on the deadliest countries list with population between 45 million and 99 million.
The new wave starting means I should update the table for most impacted countries based on case counts alone. Prior to this week, I tracked countries with > 250,000 cases. There are now too many of these to make this table meaningful, so in days ahead, I will update the methodology to report countries with > 500,000 cases. Stay tuned. 

Instead, here is the list of countries and regions with > 3 percent of total global cases:

Most of these are now starting a new wave of the pandemic. 

1/4/21: COVID19: Europe and EU27

 Both Europe and the EU27 are now in a new wave, Wave 3, of the pandemic, just as the rest of the world ( There is no denying that fact:

Over the last 4 weeks, average number of weekly cases is up massive 37% compared to prior four weeks' average in Europe and a whooping 40% in the EU27. Deaths are lagging 4-weeks on 4-weeks changes, so by this metric, we are seeing a decline of 18% in Europe and 15% drop in the EU27. But, controlling somewhat for lags, current latest weekly death counts are up 11% on 4 weeks average in both Europe and the EU27. 

Sign of things to come: week 12/2021 rate of new cases is up 22% on 4-weeks average in Europe and 19% in the EU27. So the data suggests things are more likely to get worse in terms of both, new cases and new deaths. 

Brace yourselves...
