The corona virus is also spreading faster and faster in Switzerland. But lead tracers can no longer cope with the rapidly increasing number of cases in many places. Chains of infection can no longer be reliably interrupted. This is reported by the “SonntagsZeitung”.
Consequently, contact tracing no longer works as it should, even in the most populous canton of Zurich. The tracking team is so overloaded that cases of infection have to alert their possibly infected contacts and send them to quarantine. This was confirmed by Lina Lanz, spokesperson for the Zurich health department: “The index cases report to their contact persons and thus participate actively.”
Thus, the Zurich contact trackers have lost track and control of the infection process. There is no longer any guarantee that the chains of infection can be broken. Meanwhile, there are a growing number of cases where the scan failed and infected people may not have been informed.
Avoid contamination at all costs
Other cantons are in a similar situation. Consequently, in many places only 10 to 20 percent of newly infected people had already been quarantined at the time of the positive test. According to Berna epidemiologist Nicola Low, the rate of those who are already in quarantine if their infection is confirmed would have to be increased to 80 percent to break the chain of infection.
The experts ask the cantons to take the necessary measures to avoid a second wave. Even if contact tracing doesn’t work properly, even if it is better than the alternative, Marcel Tanner, epidemiologist and member of the federal scientific working group Covid, is quoted as saying: “Neither a crash nor an infection should now be seen as a solution, that would be economically and socially fatal. “(kes)
