According to the recently negotiated Infection Protection Act, which the Bundestag will vote on this Wednesday, districts or cities must impose night curfews with an incidence of 100 or more.

Up to a value of 100, purchases can be made beyond what is essential for life, from 150 customers should only pick up the goods they have ordered.

Schools, in turn, should close their doors from a value of 165.

With so much number acrobatics, the question arises as to how reliable the numbers determined by PCR tests are at all.

There has been criticism of their informative value in science for a long time.

“We come to the conclusion that the total incidence should not be seen as 'the measure of all things',” said an analysis by LMU Munich on March 19.

Statisticians headed by Professor Helmut Küchenhoff had found, among other things, that the increase in new infections in the younger age groups had risen suddenly by 30 percent on March 10 - two days after the first free rapid tests in pharmacies.

Although the incidence is the earliest possible information about the occurrence of the infection, it is also prone to failure.
