   The loss of furin cleavage and some RBD mutations seems like it might be non-human

   There are about 100 681S human genomes on GISAID and some evidence of transmission clusters so can't be a totally unfit virus in humans

   THe FCS will still be there but most likely not as good as P681R. Totally agree about the N501 S or D maybe non-human. That could be spillback followed I guess by another spillover..

   That is a weirdly mutates spike... Often we see charge reversions, but that's not what's going on here - instead we see several hydroxyl groups? There are more S/T mutations in that spike than the two you mentioned. Novel receptor?

   This is highly confidential right now but it is from wastewater in a city. It has been frequently coming up over time and has not been seen in any of the human cases in the city (and as you know we do sequence a lot). We are speculating it is in rats or something.

   The good news is probably that this will be less fit in humans and is not a particular threat (above Delta which wealready have). Would be interesting though.

   Very interesting!

   Indeed - that is interesting. As you say, could likely be animals, but yes, probably not a concern in humans compared to delta.

   Don't rodent CoVs have funky FCSs? Question for Stephen...
