This is quite an interesting piece. I was aware of this form of CV but had no idea it stayed infectious for 41 days! 'I've had 'gastric coronavirus' for weeks - why is no one talking about this version of the virus?' https://www.telegraph.co.uk/health-fitness/body/had-gastric-coronavirus-weeks-no-one-talking-version-virus/

The other thing about this is: imagine the economic consequences of having a large chunk of your workforce off sick for 62 days!

Another thing abt this: I've no idea how these things work, but if CV can attack the stomach as well as respiratory system cld it also attack other things. eg Cld the "asymptomatic" folk actually have - I dunno - verrucas or nerve damage or bone tissue problems or something?
