A difficult key factor
At the beginning of the corona pandemic, the R0 value was an essential criterion for estimating the further development. A study by the University of Würzburg now shows that it was often not really accurately determined. Just to remind you: In 2020 - at the beginning of the corona pandemic - the whole of Germany was fascinated by the so-called R-value, which was published daily in the media. If it was above 1, it was clear that the pandemic would continue to spread. A value below 1, on the other hand, promised a decline in the number of infections. Values of more than 2, as calculated by the Robert Koch Institute during this time, did not bode well: they stood for an exponential spread of SARS-CoV-2. However, a study now published in the journal Scientific Reports concludes: In reality, the R-value was significantly lower than previously assumed.
