Why is the Mortality Rate of Coronavirus so Dissimilar in different countries?

Posted by

I wrote a post on this exact issue on April 9.

I have been doing Data Analytics Studies on the Coronavirus Pandemic for 38 days. The 28 countries have been chosen for the Studies as they are either amongst the 22 with the highest number of cases (over 13,500), or because they are amongst the 11 most populated nations on earth (over 125 million). It is because of the second reason that Indonesia, Pakistan, Nigeria, Bangladesh, Mexico, and Nigeria are part of the Study.

The chosen 28 countries comprises 2,251,436 COVID-19 cases, which is 90.1% of the total 2,499,011 cases reported worldwide by 11:00 am UTC/GMT yesterday, and is therefore more than a good reference sample.

The average “Mortality Rate” (number of deaths as a percentage of those who had tested positive for Coronavirus) for the 28 countries is 7.3% (up from 6.2% on April 9). The median is 4.9% (up from 4% on April 9).

The average Mortality Rate is 12% (up from 10.8% on April 9) for the Top 10 countries in this Study, 5.1% (up from 3.8%) for the Middle 10 countries, and just 2% (up from 1.9%) for the Bottom 8 countries.

Is the Mortality Rate high due to the high median ages (in brackets after each country’s name) in Italy (45.5 years), Spain (42.7), Netherlands (42.6), Belgium (41.4), France (41.4), Sweden (41.2), and UK (40.5)? If that is so, why do Mexico (28.5) and Indonesia (30.2) have high Mortality Rates?

On the other hand, why is the Mortality Rate so low in Japan (median age 47.3 years), Germany (47.1), Austria (44), Portugal (42.2), and Canada (42.2), which also have relatively high median ages?

Do scientists or healthcare professionals have any explanations?

Also look at the column titled “CHANGE”. Data for 5 countries is missing as these were not part of my Studies on April 9. Why has the Mortality Rate shot up so much in Belgium and France? Even more surprising — how has it come down in Bangladesh?

Is something wrong with the way India is conducting tests or reporting data?
