Has the focus of the Corona requirements been set incorrectly?
Experts on aerosols - the air mixtures in which the virus also floats - appeal to politicians.
It is considered certain that the coronavirus * spreads mainly through the air.
Researchers therefore consider the measures taken by the federal government under Chancellor Angela Merkel * (CDU *) to be insufficient.
Now they are making recommendations for behavior in lockdown * - curfews are not among them.

"Those who meet for coffee in the pedestrian zone do not have to invite anyone into their living room": Leading German aerosol researchers are calling for a different corona course.
"If we want to get the pandemic under control, we have to make people aware that the danger is lurking INSIDE," said a letter to the federal and state governments.
It is available to the

.
"Unfortunately, to this day, the essential findings of our research work have not been translated into practical action," the authors criticize.
Measures would need to be taken in homes, offices, classrooms, residential complexes and care facilities.
They warn that infection occurs indoors even if you do not meet someone directly, but an infectious person has been in a poorly ventilated room beforehand.
Debates about strolling on river promenades, staying in beer gardens, jogging or cycling, however, are counterproductive.
Researchers criticize the Merkel government's Corona course - and reject curfews
Measures such as compulsory masks when jogging along the Alster and Elbe in Hamburg are more of a symbolic nature and "do not have any significant impact on the infection rate," the experts write.
Sars-CoV-2 pathogens * would almost without exception be transmitted indoors.
This is extremely rare in the open air, in the alcohol range.
The letter says that the limited resources should not be wasted on this.
Also, large groups - so-called clusters - are never infected outdoors, as can be observed indoors, for example in homes, schools, events, choir rehearsals or bus trips.
From the point of view of the scientists, the curfews also promise more than they can deliver.
"This does not prevent secret meetings indoors, but only increases the motivation to evade government orders even more," they write.
"Wearing a mask in the pedestrian zone and then having a coffee table in your own living room without a mask is not what we as experts understand by infection prevention."
With exit restrictions, politicians want to prevent people from ever meeting at all, according to the letter.
Corona in Germany: aerosol researchers recommend indoor masks
Instead, the authors recommend several measures such as making meetings indoors as short as possible, creating conditions such as outdoors with frequent intermittent ventilation or cross ventilation, wearing effective masks * indoors, and installing room air purifiers and filters wherever people spend longer periods of time Have to stay in closed rooms - for example in nursing homes, offices and schools.
“The combination of these measures leads to success,” it continues.
"If this is communicated appropriately, people will regain some of their freedom of movement in this difficult time." The signatories include the President of the Society for Aerosol Research, Christof Asbach, General Secretary Birgit Wehner and the former President of the International Society for Aerosols in the Medicine, Gerhard Scheuch.
