The Financial Times has just published a special live updated charts within a pandemic coronavirus, where you can check and compare the situation in their own country with others.
Cases of disease and death grew around the world for weeks, but now many European and Asian countries believe that the peak incidence behind them, systematically removing previously imposed restrictions, which already led to a serious economic crisis in the world. You can not hide, however, that tracking further cases on the basis of data provided by the individual countries is difficult, especially if we compare them with others, so increasing numbers generated special charts, like the one just presented by the Financial Times. They are interactive, so allow you to comfortably explore and compare the information available so far on a global scale, gaining wider perspective.
It is worth noted, however, that estimate the scale of the pandemic on the basis of detected cases CoVID-19 can strongly pass the reality, mainly because it is closely related to the number of tests performed, so the higher the number the general could mean just a lot more of the tests. Definitely better suited for this purpose deaths, although here there are differences in the classification of causes of death and, in some countries, deaths from CoVID-19 is considered only in the hospital. Either way, both values were on the chart, but you should be aware of their limitations – served figures are an average of 7 days to be able to take account of possible administrative changes.
Interestingly, in the case of certain parts we can see the expanded data on mortality, ie. The difference between showing all deaths during a pandemic and the historical average. The inventors of this solution was decided to use a logarithmic scale, i.e., one in which the measured value of the physical quantity is converted by a logarithm – the same distance on the scale represents the division / multiplication with the same value, instead of adding / subtracting the same value as the linear scale . That’s because it is better suited to providing such data as the spread of the virus, because it allows you to compare the state of the epidemic in places where only it starts with these, where the number of cases is much higher, although they have very different overall number of cases.
And what with the number of inhabitants? Most often it is not a consideration in cases such as pandemics, because the viruses do not pay attention to the limits and have no major impact on the rate of spread. You can not hide, however, that the comparison of cases in countries strongly differing in the number of population is not the best idea, because it can be fooled if a wrong sense of security, or on the contrary – for example, 80,000 cases are completely different dimension in China or the United States than in Poland nettricks. Therefore, depending on the compared places, sometimes it’s better to look at the number of cases per million population, and sometimes the total number of cases.
