Covid-19 - Globally

The following statistics are from the Johns Hopkins University site (https://github.com/CSSEGISandData/COVID-19/blob/master/csse_covid_19_data/csse_covid_19_time_series/time_series_covid19_confirmed_global.csv)

Total deaths/confirmed cases (click on the chart for more information)

Observations among these countries:

• Iran was the first of the big 10 countries to record confirmed cases and deaths. The US followed about 2 weeks later.
• Iran peaked at the end of March. Iran's daily confirmed cases per capita hen dropped until the start of May after which they surged again and have held steady after the second week in June.
• The US daily confirmed cases per capita started to decline after the start of May but then increased again in the 30 days starting in the 3rd week of June.
• Russia's daily confirmed cases per capita caught up with the US at the start of June, then after tracking the US until around June 16th and then continued its downward slope while the US increased.
• Chile has the largest number of daily reported confirmed cases per capita from the 4th week of May to the 4th week of June.
• India's daily confirmed cases per capita and. deaths per capita have not peaked yet.
• Looking at the ratio of daily deaths/confirmed cases:
  • Mexico has more than a factor 2 (nb. the y scale is log base 10) daily deaths/confirmed cases than any other country.
  • Russia and S. Africa have the lowest daily deaths/confirmed cases since the end of June.
  • Brazil, the US and India have reduced their ratio over the last two and a half months while Chlle's and Russia's has increased

Countries with the leading numbers of cases 7/28/2020

As of 7/28/2020, the US leads in confirmed cases :

The US also leads in the number of deaths:

If one normalizes by dividing by the population then the United States drops to eighth in the world in reported confirmed cases per population:

and drops to 9th in deaths per population.

In terms of deaths/confirmed the Unites States drops to 55th highest among 179 countries.

Daily cases

Looking in more details the leading countries by confirmed cases per day per 1000 population on July 31st were:

And by deaths:

Comparing the spread of Covid19 in Canada and the US with larger W European countries

Confirmed Cases

It is seen that Italy was the first country whose Covid-19 confirmed cases spike. This was followed by Spain then Germany and France.  Germany was particularly successful in suppressing its peak. The UK has a long tail and the virus has just run away in the US which now has about 10 times more confirmed cases as the other countries with the exception of Spain. Recently Spain has seen an uptick in cases

Deaths

It is seen that US deaths / day / capita are over three times that of the nearest competitor (UK) and over 10 times greater than the next competitor (France)

Possible correlation of Covid-19 cases per capita versus median population age for world's countries

The median population age varies by country from about 15 to 50. The 15 countries with the lowest median population age are all in Africa.

Since Covid-19 death rates appear to be higher for older people (see for example https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/COVID-19/COVID-19-Cases-by-Age-Group.aspx for California), we looked at the Covid-19 deaths per capita  for 179 countries versus a country's population median age. However, there appears to be very little correlation.
