13/3/21: COVID19 Update: BRIICS

Previous posts covered updates for Covid19 pandemic stats:

In this update, let's take a look at the dynamics of the pandemic in BRIICS (Brazil, Russia, India, Indonesia, China and South Africa) group of countries.

First, weekly case counts:


Brazil is leading BRIICS into what appears to be a new wave, Wave 4 of the pandemic. All other BRIICS countries are showing sustained moderation in new cases. There is also a much smaller uptick in new cases in India.

A similar picture emerges from weekly deaths data:


A summary table of per capita cases and deaths, as well as mortality rates.


One feature of the above dynamics is the state of uncertainty these highlight in the Emerging and Developing economies with respect to the recent improvements in the pandemic numbers. Sitting in the West, it is, perhaps (depending on the location) easy to slip into a state of overconfidence and complacency, as vaccines become more widely distributed and politicians trumpet the sight of 'normalcy' on the horizon. The problem with this worldview is three-fold:
  1. This pandemic will not go away until we reach - globally - levels of vaccinations and infections that deliver global 'herd immunity', which would require 90%+ immunity cover; and
  2. As long as there are large pools of the virus in the world at large, there will be higher likelihood (note: we do not know probability) of virus mutations that can render acquired immunity irrelevant, and
  3. We are currently not doing anything near enough to deliver vaccines to the countries outside the Advanced economies world.
