12/9/20: COVID19 Update: Worldwide Cases and Deaths

The global COVID19 pandemic is refusing to go away. Day 247 and the dynamics of new cases and daily deaths remain as worrying as ever, just as the public and the politicians have largely settled into the strange 'ignore and forget' pattern of thinking about the threats.

Here are the daily new cases and deaths charts:

Key takeaways from the above two charts are:

1. There is no amelioration in the pandemic dynamics in terms of new cases: we are still at the peak levels of contagion worldwide.
2. Earlier hopes for decline in new cases worldwide has now been replaced by a re-acceleration in the new cases arrivals.
3. Historical average daily new cases is 115,366. Last 30 days average is 263,940 new cases per day and last 7 days average is 267,832. The pandemic is getting worse, not better.
4. Historical average daily deaths is 3,710. In the last 30 days, the average has been 5,603 and in the last seven days, 5,863. 
5. The peak of daily deaths occurred back in mid-April owing to a number of factors, that can be considered as exceptional. These include heavy concentration of COVID19 cases, lack of medical experience in treating COVID19 cases, demographic biases in early wave of COVID19 cases, and so on. On-trend, the peak was around 7,000 daily deaths.
6. Since the peak, daily deaths counts did not decay beyond the local trough around the end of May - a trough that was less than 50 percent lower than the peak (not an impressive moderation for a pandemic). The trough was set at around 4,050 daily deaths.
7. Since then, however, matters worsened once again, with a new local peak reached at around 6,000 cases in the last week of July. Deaths counts have been bouncing around 5,600-5,700 daily cases since then.

These worrying numbers are confirmed by the dynamics - the rates of change in the series:

As you can see from the chart above, the data is exhibiting a risk of rapid re-acceleration in the pandemic dynamics in terms of both, new case numbers and deaths. Of course, the data is volatile, so it is hard to tell if the new re-acceleration of growth rates to 15.8 and 24.4 percent for new cases and deaths, respectively, is going to hold. Nonetheless, nominally, we are no longer witnessing the second derivative (acceleration) moderating. Which means we are at a risk of rising severity of the already horrific trend. 

Here is a handy summary table of comparative growth rates:

Please note, these are growth rates that are already smoothed by using 7 days average! 

Fir numbers geeks amongst us, here is a summary table of comparatives for 33 countries, plus the EU27, that have more than 100,000 cases reported. Last time I updated these figures on August 30, there were 30 countries in this club.

Due to deterioration in the global pandemic conditions, EU27 is now ranked as an 'average' (statistically) territory. The U.S. remains 'worse than average'. 

The same table by aggregating countries by some internationally-recognized groupings:

And a descriptive statistics table for all countries with > 100,000 cases:

In summary, the pandemic is not going away. We are months before the start of the 'normal' flu season in the Northern Hemisphere, when temperatures outside force much of the activity - work, social, personal - indoors and into closer proximity to others. More inclement weather is coming to the largest concentrations of people on Earth, not only in Europe (already living through the second wave of the pandemic) and North America (still struggling with the first wave), but also to Asia-Pacific and the likes of India (which already outpaced Brazil to the second place in terms of infections after the World Series leader, the US of A). 

The brighter news on the horizon, currently, are the news relating to the vaccines development. But these vaccines are unlikely to hit mass markets any time soon, at least not before the October-November flu season onset.
