De Montfort University has published an update regarding their recent study on climbing chalk and the relative deactivation of coronavirus on chalked, plastic surfaces
Yes, that’s what I understand from this study too. So best case scenario from this research is we don’t have to worry about gymnasts sharing the same chalk block/bucket or cleaning bars between gymnasts(which is actually pretty great). It doesn’t say anything about gymnasts crowding around a chalk bucket breathing and coughing in each other’s faces, study wasn’t about chalk helping reduce transmission of airborne COVID in close contact situations.Right, but that's not how chalk might possibly kill COVID. This is all about surfaces.
