I'm not saying that I believe all data available to #OriginOfCovid has been shared. But if you're going to use the data provided by the Chinese CDC, you should at least pay attention to the methods by which they collected that data.
Nonetheless, you cannot infer host by the abundance of reads in a surface sample. We don't know what was on the surface that was swabbed. Was a slab of raccoon dog meat on the table before it was swabbed? x.com/ayjchan/status…

I was initially mistaken in thinking that a whole genome or exome enrichment kit had been used to pull off human genetic material from the samples. It's more likely that an enrichment kit was used to pull down virus genetic material.
Nonetheless, it's nonsensical to use ratios of genetic material from a surface sample - especially one that has been processed so that non-viral material is lost - to infer the host species that shed the virus into the environment.
