I don't understand any choir being compatible with any definition of social distancing. If the German Govt is asking you to practice social distancing it means meeting another person at a distance. You can not continue your choir. What is social distancing? Social distancing measures are steps you can take to reduce the social interaction between people. ...

The higher transmissibility of this VUI-202012/01 strain (if it is confirmed) is almost certainly due to mutations in the spike gene of the virus; see preliminary report from COG UK; another version of that with slightly more analysis confirms that one of the (17) mutations involved had been previously confirmed as causing higher transmissibility in a mouse ...

According to this March 2020 article, "no studies have directly evaluated the biophysics of droplets and gas cloud formation for patients infected with the SARS-CoV-2 virus". But the author, MIT Prof Lydia Bourouiba, says exhalations can cause gaseous clouds that travel up to 27 feet.

No, it just happens and you're overthinking about it. It means absolutely nothing. Cough is a protective reflex, which helps to clear the large breathing passages from fluids, irritants, foreign particles and microbes. A cough can also be psychogenic or neurogenic but certainly not telepathic or magic. What causes coughs: Most coughs are caused by cold ...

A relevant, unique research paper I found with particular relevance for COVID-19: Hypothesis: Nasal vs. oral inhalation accounts for the severity of COVID-19. People who lose their sense of smell apparently generally experience milder cases than those who do not. This paper theorizes that when a higher percentage of coronavirus particles enter through the ...

I agree with Mark, administration route probably doesn't matter because none of these were shown to work. ColdZyme has an open-label trial but which found no reduction in incidence, and only a very modest reduction in symptom duration. They do mention and even have more recent in vitro trials, but those results insofar don't hold in vivo for reasons that ...

I can't find any evidence that the oral sprays you list work. The ColdZyme website, for example, lists exactly zero studies, and specifically disclaims being a medicine. Taffix claims that a number of studies have been done, but the only in vivo study was very low quality, being an unblinded study. In short, these give strong evidence of being "snake ...

Data suggests droplets remain in the air up to 3 hours, and longer for droplet nuclei. Where they go depends on the local temperatures, humidity and air flows. The image shows a cough on the left and a sneeze on the right. Currently, the term droplet is often taken to refer to droplets >5 μm in diameter that fall rapidly to the ground under gravity, ...

There is a recent paper The role of community-wide wearing of face mask for control of coronavirus disease 2019 (COVID-19) epidemic due to SARS-CoV-2 in The journal of Infection, 2020 Apr 23 doi: 10.1016/j.jinf.2020.04.024 The Conclusion Community-wide mask wearing may contribute to the control of COVID-19 by reducing the amount of emission of infected ...
