Testing transmissibility of SARS CoV-2 in ferrets

This may possibly have some actual research on SARS CoV-2 and masks. Ferrets.

"The study comes weeks after the US Centers for Disease Control and Prevention acknowledged that the novel coronavirus can spread via aerosols. The agency updated its guidelines to include airborne transmission in mid-September, but removed the language the next day. If the virus were found to spread among people predominantly through aerosols, Marr says, that would carry practical implications for recommendations of types of masks and ventilation systems best suited to filter out airborne particles.'

In other words, recommendations for masks haven't been based on science. This may help with that.

I think this was a very clever, but very small test using SARS CoV-2 (2019) SARS (2003) and H1N1 (2009). Their transmissibility differs, and it really doesn't have anything to do with who was president of the United States when the virus appeared. Some viruses like SARS and MERS have had death rates up to 50% yet have disappeared quickly. There was no way to know at the beginning. Again, nothing to do with who was president, or who the science advisors were. That's all politics. When Democrats say that, remember, it's politics and they want to elect Biden. When the science disagrees, that's just science. Picking those you wish to believe may be more politics than science.
