Reproduction number, doubling time, infections – what metrics are important

A Doctor handled a Coronavirus Test. The starmaps show the doubling times for the world and Germany

On (at least) three key figures, politicians and scientists are looking in the Coronavirus pandemic, particularly:

1) the number of new infections

Firstly, as the number of confirming infections with the Coronavirus. This increases both, according to data from the Robert Koch Institute (RKI) as well as those of the American Johns Hopkins University resistant. This is not different, because new cases daily adds, Convalescent and Deceased but will not be deducted again. Current Figures for all German districts and cities, you can find here.

2) Reproduction Number R

In addition, the so-called basic reproduction number R0 is important. It indicates how many other people an Infected person on average infects. The value is greater than 1, spreads a disease. First according to scientific estimates, the R0 value at Covid-19 according to the RKI between 2.4 and 3.3, other institutions have referred to different span widths. The value changes, scientists speak of the Effective reproduction number R. This was the RKI, according to Germany under 1, which means the number of new infections are among drops (more about this here).

This graph is the Robert Koch Institute (RKI) published in its epidemiological Bulletin of 23. April. As the chart from the 15. April also shows this Graph, the estimate of effective reproduction number R (blue curve). This provision was according to the RKI, however, until the end of March.

3) doubling time

Thirdly, there is the so-called doubling time, which is also of German Chancellor Angela Merkel as an important indicator for the evaluation of the measures was called. This is the time period in which the number of Infected doubled. The doubling time can be so good to see how strong an epidemic is progressing. In contrast to the case of numbers it is good if the values rise, because a high doubling time relieves the health system of potentially (more background and a sample calculation, see here).

Note on data: The Germany graphics are based on data from the Robert Koch Institute, the world map on data from the Johns Hopkins University. Because both raise your Numbers differently and communicate (more on this here and here), are to be found in the data sets have different values.
