Coronavirus: Are mutations making it more infectious?

This coronavirus is actually changing very slowly compared with a virus-like flu. With relatively low levels of natural immunity in the population, no vaccine and few effective treatments, there's no pressure on it to adapt. So far, it's doing a good job of keeping itself in circulation as it is. The notable mutation - named D614G and situated within the protein making up the virus's 'spike' it uses to break into our cells - appeared sometime after the initial Wuhan outbreak, probably in Italy. It is now seen in as many as 97% of samples around the world.
