How coronavirus spreads

After my latest post on the Covid situation in France, I had quite a lively discussion with a number of you. This prompted me to look out an article which best explains how the virus is transmitted through the air, particularly indoors. Sadly, there’s too much information out there, much of it misinformation.

This excellent article (link also below) from the Spanish newspaper El Pais (albeit in English) beautifully illustrates the issue using the example of a living room, a bar and a classroom. While the coronovirus is not as infectious as measles, scientists now openly acknowledge the role played by the transmission of aerosols – tiny contagious particles exhaled by an infected person that remain suspended in the air of an indoor environment for up to nine hours – yes, that long!

How does the transmission work? And, more importantly, how can we stop it?

To end on a more lighthearted note, here’s a cartoon from one of my (many) cycling friends, which makes the same point.
