Corona warning app: “red lamp does not automatically mean high risk”

Corona warning app:'rote lampe bedeutet nicht automatisch hohe gefahr''rote lampe bedeutet nicht automatisch hohe gefahr'

Nevertheless, not all the details of the core process of the National Corona Warn app are known that officially imagine politics and participating companies on Tuesday. Sure, however, it is that it is one "red signal" would give if a user had a risky contact with a coronavirus infected, Ute Teichert explained director of the academy for public healthcare, on Monday at a web conference of the Science Media Center (SMC). These" red lamp" mean "not automatically a high risk".

A chain of events

Teichert called a warning through the app as "a note of several in a chain of events that you have to look at". The affected user is only called the day of an increased risk of infection, not the time. He also experiences multiple contact with infected. There is a recommendation in such a case, the location health department, call the on-call service 116 117 or the family doctor.

At the behavior, the normal task of risk demonstration, in which they worked after an individual contact personnel scheme, succeeded in the chairman of the Federal Association of Arztinns of the Public Health Service. They had to find out how closely coincidence had been on a said day, whether people had gone with or without mouthguard on clothfooling and had chosen about. Every note should be further verified.

With the app, Teichert sees an appeal connected to the public: "We want to get the pandemic" and infection chains to stop sucking sudly. But she also seeks politics and administration. "But we have to increase staff as well." Even if you do not ame that the number of potentially infected with the mobile application rasige, the technical tools would lead to multi-work at the Amters at a time, where they have already had too few employees and they have accessed them since Marz auxiliary favers just retrieved them became.

Do not leave alone with the warning

"You can not leave people alone with a warning", is the practitioner clear. If further steps were considered to be notified, currently attached at least sufficient testing capacity in the high level of around one million per week, of which only 400.000 were used. But there is still "Problems with the laboratory interfaces" Inspired. Some of the facilities are not yet sufficiently digitized. They are not considered to spend QR codes with which a user will warn a positive result contacts.

Until then, the verification process will run over a hotline, enamed Teichert Fruhere reports. The additional loop should soon be dispensable, since all test institutes were successively connected to the system. In principle "All laboratory results are cast", Only with the right counter-feeder KONNE "The gate is open" become what in the decision of each lounger. This aspect of voluntariness is very important in the interest of the acceptance of the app in the population. For the health markets "But is it a bit too bad", that it "No replacement of the data gives".

Currently, around 53 percent of the Bundesburgs are ready to install the application, Cornelia BeTsch reported as the initiator of the market research project Covid-19 Snapshot Monitoring (Cosmo). In this proportion, the willingness is very high to share results data with third parties. The numbers have risen over time, which for the decentralized storage approach and a high degree of trust in the resistance. She also underlined: "Voluntary is a very important feature." One "Quasi-commitment" will "perceived as more effective", but "Nevertheless, rejected".

Clear instructions sooty

A person who receives a warning, according to the Erfurt professor for health communication "very clear instructions, what you should do". Alone the note: "Call the doctor", Do not be sufficient. The health markets had to "Sustainable information" ie how it continues to be concrete for those affected and whether they could still finish ongoing shopping. In principle one is one "Self-Quarter" until recently "relatively well accepted" been.

Betsch recommended to emphasize the social users of the app and from one "Citizen Science Project" to speak: "We all help to learn something about how to get a pandemic." In addition, the social life can continue with the application rather on. "Anyone who uses the app is a profit" and bring new insights, insured attendants. The more, the better, but you can not be oriented here at a fixed point.

The technique used in Germany and Switzerland with spacer via Bluetooth based on the succinct interface of Apple and Google, Marcel Salathe, Professor for Digital Epidemiology at ETH Lausanne, as comparatively reliable. With this with one "good probability", that an infected person was near. The developers were able to set what the signal strength was considered close. Practical for about a radius of two meters.

No tide of clues expected

First experiences from Italy show according to the Swiss that one "Do not get thousands of alarms". If the app is connecting, this is one "Good foundation for tests". Applications that worked with the decentralized protocol are also quite simply compatible and sharing codes with the system of another country. "Certain old gerate" could not use the interface whose number are moving "in the deep single-digit area" or at least ten percent".

Plane from Apple and Google to directly integrate the function into your operating systems, buried Salathe: users already had to trust the two tech corporations often in protection "our intimate secrets" and now in this case ame, "that the data is not secretly still to you" walk.
