Restrictions are loosening. Offices are also getting fuller with workers returning after working from home. However, if you rely solely on distancing regulations and masks to contain the corona virus, there is a high risk of infection. It is especially in closed office rooms with low humidity that the risk of infection lurks in the form of so-called aerosol particles, i.e. tiny exhaled infectious floating particles. This is why physicist Roland Netz from the Berlin Freie Universität recommends professional humidification. This means the droplets cannot shrink so quickly and tend to sink to the ground as heavier droplets.
Town halls, retirement homes, libraries and museums are gradually returning to normal. But the virus is still around, and anyone who relies solely on distancing rules and wearing masks to ward off infection face a high risk of infecting themselves and others. Especially in closed office rooms with low humidity, the risk of infection lurks in the form of so-called aerosol particles, i.e. tiny infectious floating particles that are exhaled. That is why physicist Roland Netz from Berlin’s Freie Universität recommends professional air humidification. In this way, the droplets cannot shrink as quickly and are more likely to sink to the ground as heavier droplets.
It’s been in the air for a while! ´The Robert Koch Institute has now also confirmed that the coronavirus spreads via the air in a room. In order to reduce this risk of infection, PC retailer, Notebooksbilliger.de, is using more stringent coronavirus protection measures in its reopened store in Munich, even measures that go beyond the legal requirements. Trotec’s new TAC V+ high-frequency air purifier is designed to protect customers from airborne infection by filtering infectious aerosols (tiny saliva particles) out of the air in the room. According to scientists and virologists, aerosols are one of the main sources of infection for the coronavirus. If, on the other hand, the air in the room is permanently and effectively “cleaned”, in short time intervals, the risk of infection via aerosols released when speaking or coughing is significantly reduced.
The Heinsberg district continues to keep the world in suspense! Parcel delivery company DPD has therefore had to close its parcel centre in Hückelhoven (in the Heinsberg district) due to a massive corona outbreak. As it stands, at least 42 of the total of 400 employees have been tested positive for the coronavirus. However, more than 200 test results are still pending, expected on Monday. In order to prevent a further spread in the district, the public health department is checking people that may have been in contact with those infected and all 400 employees are in quarantine.
Austria will not rest easy. After the holiday resort of Ischgl hit the headlines as a hot spot after a bar supposedly played a major role in spreading the virus throughout Europe, two mail distribution centres have now also been closed. In the Hagenbrunn distribution centre near Vienna, 68 of the 650 employees tested positive for the corona. At the Inzersdorf distribution centre, 70 employees are currently infected. According to the newspaper Krone.at, a temporary employment agency is said to have brought infected employees to the distribution centres, but it has not yet been conclusively determined whether infected employees also delivered parcels and letters.
To reduce the risk of infection in libraries, Trotec has developed the new TAC V+ high-frequency air purifier. Infectious aerosols (tiny particles of saliva), which, according to the Robert Koch Institute, transmit the virus through the air in a room, are filtered out of the air by the TAC V+ by 99.995 %. According to scientists and virologists, aerosols are one of the main ways in which the coronavirus is spread. If the air in a room, however, is continuously and effectively “cleaned”, the risk of infection by aerosols released when we speak and cough to almost zero.
What Trotec has been warning everyone about for some time has now been proven by another scientific study: The SARS-CoV-2 virus is transmitted not only by coughing and sneezing, but also when speaking. A study published in the journal “Proceedings of the National Academy of Sciences of the United States of America“ (PNAS)” shows that aerosols (tiny saliva particles) ejected when speaking just one sentence float around in the room for a long time. This insight is not new. “A large proportion of corona infections are due to droplets and aerosols,” explains Christian Drosten, Director of the Institute at Berlin’s Charité Hospital, adding that only around ten per cent of the spread of the virus is the result of direct smear or contact infections.
As of this week the first hotels are allowed to open again! However, distance rules and strict hygiene requirements apply to all hotels to protect employees and guests from infection. The fear of the coronavirus is so great that even after the reopening many beds as well as seminar and conference rooms will remain empty. The situation is further aggravated by the fact that regulations vary from state to state. Hotels in Hamburg are only allowed to rent out 60 per cent of their rooms. Lower Saxony “allows” just 50 per cent. These regulations are supplemented by rules on social distancing, compulsory masks and increased disinfection measures. Far from rosy prospects for the already troubled hotel and restaurant industry.
In its most-recent Corona profile, the Robert Koch Institute has confirmed the dissemination of the virus via aerosols in the indoor air that we breathe. To reduce this risk of infection in nurseries, Trotec has developed the innovative high-frequency TAC V+ air purifier to filter infectious aerosols (tiny saliva particles) from indoor air. According to scientists and virologists, aerosols are one of the main sources of infection with the coronavirus. If, on the other hand, the air in the room is constantly and effectively “washed”, the risk of infection via aerosols released when speaking or coughing is significantly reduced.
The news that more than 100 Westfleisch employees have contracted the coronavirus in the midst of the current debate on relaxation has come at a very inconvenient time for politics and the economy! This case shows powerfully that the measures first imposed by regional and federal governments weeks ago are only partially effective. They are only effective if people keep a large enough “safe distance” between each other, in addition to all of these hygiene measures.
