Pro tests

Our assumption that Italy and Spain passed the maximum number of active cases of infection in mid-April has confirmed. Today's table differs from the previous one by adding three columns: the Absolute number of tests, the Relative number of tests, and the Relative number of detected cases. Also, Peru was added instead of China due to the lack of Chinese statistics of tests.

Table 1 shows that in comparison with the Asian stage, a greater number of days is required to reach the maximum number of active cases: previously, 20-40 days, now - 80-90.

Tab.1

More than 5% of the population was tested in Spain, Belgium, Portugal and Israel, and less than 1% - in Iran, Brazil and India. (Hist.1)

Hist.1 Relative to the population number of tests (blue) and the relative number of infected (red)

In terms of the relative number of infected, the USA, Spain and Belgium are ahead (more than 0.4% of the population), tailing  Brazil, South Korea, India and Australia-less than 0.1%. (Chart 1)

Chart 1 Number of infected as a percentage of the population (blue) and number of deaths per 100,000 population (red)

More than 32 deaths per 100,000 population: in Belgium, Spain, Italy, Britain, France, Sweden and the Netherlands. Less than 9 – in India, Australia, South Korea, Russia, Israel, Turkey, Austria, Brazil, Peru and Iran.In Table 1, the 4th column from the end shows the countries that passed the first wave of the epidemic. In the third column from the end, the yellow cells indicate that the wave is close to its apogee and the brown ones indicate countries where the end is not yet visible – Peru, Brazil, Russia, Sweden and India.

The most backward medicine - in three neighboring countries, where the number of deaths relative to the number of cases is highest, %:·

3     Britain    14.4·

2     France   15.3·

1     Belgium  16.4.

And, the most intriguing, 4 countries with the most advanced medicine. In the 4-th column of  Tab.1 you can see number of deaths relative to detected cases, %. The leaders are:·

4       S.Korea     2.4·

3       Israel         1.6·

2       Australia    1.4

Based on official data, country that has the best equipped medicine in the world with the most professional doctors is drum roll :

1        Russia       0.9.

At least 2.5 billion of the World's 7.7 population can relax

In their countries, the peak of the epidemic has either passed, or it will happen in the next five days. Today is April 11, 2020-Great Saturday for Catholics. And today, in Italy and Spain, the maximum number of infected people (Active Cases) is recorded, after which COVID-19 will go down.

En toda España cielo despejado

The table below shows the countries with the highest number of infected people. Mortality relative to the number of infected people varies from 0.78% in Russia to 12.77% in Italy (4th column). If the number of deaths is attributed to the number of residents, the spread among countries where the peak has passed will be as follows,%:

Australia 0.00022

China 0.00024

US 0.00569

Italy 0.03129

Spain 0.03472  (6th column).

When will this disease go away? part 2

                                                                    - Please  tell me, when will this disease go way?

 - According to the news, only in 2036 
(Joke)

   Now about Russia, where rulers also chose the Chinese version of the fight against infection. A little information about the new flu: symptoms of COVID-19 infection resemble those of seasonal flu (dry cough, fever,  weakness). It is believed that this virus is much more virulent. Let's calculate. R0 (basic reproduction number or how many zero patient infected:  

• influenza   1.4-2.8,
• CAVID-19  1.4-3.9,
• Measles     12-18. 

But this information is not enough to predict the epidemic, you need to know the serial interval (the time between infections). For  "Spanish flu"  it is 3 days and 5 days for COVID-19. The mortality  of  the  "Spanish flu" in 1918-1919 was 5-10%, for  Corona-virus  is 0.5 (if treated), and the same 5-8% if not treated.  On average , get sick  COVID-19 for 25 days, or die after 18 day of illness.
