Coronavirus: Are the handles and doorknobs a danger?

To avoid infection with the Coronavirus, some people on the combination of breathing mask over the mouth and nose, and upturned gloves. The Mouth guard should protect against coughing fellow citizens, the gloves accidental smear infection from doorknobs, ring the bell or the handle in the streets and U-stop tracks.

Copper-viable corona viruses in the laboratory tests were up to four hours, on cardboard up to 24 hours on plastic and stainless steel, even up to three days undetectable have been, it was said a few days ago, in a study by the University of Princeton, the conquered in the social networks.

But how informative this study is, anyway? The virologist Christian Drosten (read here a portrait of him) of the Charité in Berlin, says: particularly.

The enlightenment: Christian Drosten was the most important man in Germany

Drosten holds significance for the low

In his Podcast, “The Coronavirus-Update”, produced by NDR, says Drosten, and that in the study some questions were open, and that it would be difficult to pull from the data, specific discharges for the practice. “It is not clear how much the Virus has been applied in any Form on these test surfaces,” he says. “There is just because of Virus was added to the surface. But there is a big difference, whether this Virus is in a large or in a small liquid droplet, or a drop that has almost no volume,” he continues.

Then Drosten goes into Detail: “no Matter what the surface was occupied with a Virus, after eight hours, between eight and 24 hours – there is no measurement value. In this interval, the Virus in its infectivity very rapidly, and practically on all surfaces of the same or similar.” His suspicion was that the surface was not the cause of it, but that the eight hours of that period, before the liquid droplets with the Virus completely dried is.

Distance is more important to avoid

With a real-life Situation the process is not comparable, he continues. “When we cough, for example, in the Hand, sticking the Virus to the Hand. If we take then on a doorknob, no longer is a measure of the liquid film that remains on the doorknob stick, almost. Dries, perhaps much faster than this droplet, the other as in the laboratory on the surface.”

Summarized Drosten says that you must be with such scientific data carefully. “The are not wrong. But they are so simple that the real infection is not shown, so that likely.”

Instead of paying attention so meticulously that you don’t touch a door handle any more, and no Elevator button press, you should wash on a regular basis, the hands – and enough distance to his fellow true, and to avoid, if possible, voice contact with nearby persons.
