rePolitics is necessary, science wants it too: more knowledge and clarity about the risk of contagion in the pandemic, even when it comes to things that are familiar for a long time, such as the effect of masks, distance and hygiene. . What protects me and what others? What is nonsense and what is rumor? An international group of aerosol researchers and engineers, some of whom are actively involved in Covid-19 research, have come together and addressed the most pressing questions about coronavirus transmission in a remarkable article that is available online in many different languages. The answers contain some surprises. This is because they also put many of the messages that circulate on social media and even by health authorities such as the World Health Organization (WHO) in a different light. This particularly applies to the issue of aerosol transmission and therefore one of the most important aspects of indoor virus transmission during the cold season.

Aerosol transmission has long been considered questionable, and the National Health Commission in Beijing explicitly mentioned it six months ago. But many scientists around the world, including the WHO and the US health authorities (Center for Disease Control and Prevention), despite numerous observational studies and experimental evidence, are apparently still not 100 percent convinced of that infection through invisible respiratory tract virus-containing particles from infected Los in many cases, such as decisive “superprocessor” events, are the most important source of infection for Sars-CoV-2. The result: There are regular violent debates on the internet, often only adding to the confusion.
The joint aerosol experts’ document, which is set up as a catalog of questions, is very clear on this. The starting point is the available scientific evidence. If you want to know why interiors and especially unventilated and heated interiors and crowds of people could become an even bigger problem in the coming weeks and months, you will find answers here, based on the most recent research results (and some very old and valid).
We have summarized some questions:
Why are aerosols suddenly so important to the transmission of Sars-CoV-2?
