According to the epidemiologist Mellmann, the numbers on the spread of the British coronavirus variant in Germany may be biased.
A few weeks ago it was not possible to specifically test for an infection with the mutant on a large scale, Mellmann told the dpa news agency. The tests designed for this purpose are now commercially available and are being used more frequently. That could lead to a bias in the data.
He therefore advised to view the increasing numbers from individual municipalities with caution. The se are also often due to outbreaks with related cases at certain points.
In Düsseldorf, for example, the proportion of the British variant of the corona infections increased from 27 to 40 percent on Thursday within two days. In contrast, the share in Essen was recently around 9 percent. This is in line with a study by the Institute for Hygiene at the Münster University Hospital, which Mellmann is head of. Accordingly, the British virus variant in North Rhine-Westphalia had a share of around 9 percent of the positive test results at the end of January.
