 Technical breakdown: Corona warning app: Android users report incorrect risk assessment The Corona warning app was considered a beacon of hope to get the pandemic under control. But there are always technical problems - currently with Android smartphones. © Picture Alliance / Eibner-Pressefoto / Thomas Dinges / The risk assessment of the Corona warning app is currently bothersome on some Android devices (symbol image) "Supports us in the fight against Corona " - the German government uses this slogan to advertise for the use of the official Corona warning app.

The new coronavirus has upended all of our usual calculus about seemingly ordinary activities. While the basic outlines of disease transmission have not been upended by COVID-19, there are some nuances that could play an important role in the spread of the disease.

When it comes to coronavirus transmission, there is now worrying news in the form of a new study from Great Britain.

Up until now it was assumed that coronaviruses spread in humans via aerosols. That is why singing or coughing in the immediate vicinity of other people was considered extremely dangerous.

Now a study suggests that speaking alone can actually be enough for an infection.

The corona risk can now be simulated and estimated on computers in certain situations, especially indoors. A newly developed computer by a team led by the fluid mechanic Pedro Magalhães de Oliveira from the University of Cambridge comes to unsettling results. The study was presented in the specialist journal Proceedings of the Royal Society A on January 20, 2021.

The study , which the Hong Kong team calls the first of its kind, used hamsters in two cages; one group of hamsters infected with Covid-19 and the other healthy. The researchers created three different scenarios: mask barriers placed just on cages with the infected subjects, masks covering the healthy

Corona cage could be used to simulate the corona activities on transmission lines under a low voltage and different conditions in an effective and economical way. Photon which was created by UV light as a result of corona discharge on conductors is detected by the UV detection apparatus.

It turned out that speaking alone to an infected person carries a similarly high risk of virus transmission due to the aerosols emitted as if the infected person coughed into the room.

The research team led by Pedro Magalhães de Oliveira concludes that distance alone is not enough, but ventilation is at least as important. Compared to the Guardian , de Oliveira says: "You need masks, you need space, and you need good ventilation so that these particles do not collect in an interior and they are safely removed."

Therefore distance rule & ventilation

Aerosols have been shown to play a decisive role in the spread of corona. They arise when breathing, talking, coughing, singing or sneezing.

Interesting: Large droplets don't get far, which is why the distance rule was introduced to contain the virus. However, small particles can remain active in the air for hours - that's why you should ventilate regularly and a lot.

What a recent Covid-19 flight outbreak tells us about spread on planes .
“Is flying safe?” is the wrong question.The question has new urgency, with more contagious variants of Covid-19 spreading around the world, and with the new US policy, effective January 26, that requires all passengers flying into the country to test negative for Covid-19 within three days of their flight.
