WHO: Aerosolized Particles Unlikely to Be Significant Source of Covid-19

This is, I assume, an answer to the open letter sent to the WHO last week. I took a look at the letter: it doesn't bring many data to the table unfortunately.

In fact, it advocates the precautionary principle. I can understand (but not agree with) that in a context of public safety, but those people do science, and the precautionary principle is not scientific.
