If I understand it correctly, “not airborne” means that the germs don’t travel through the air as such. But I believe they can be conveyed in tiny cough-droplets, which can travel quite a long way through the air, and remain floating about for quite a while. And then, presumably, infect any surfaces which they land on.
I don’t know that for certain, but I think it is true.
I agree with you. A sneeze lands on a surface, and it’s wet until it dries, and sometimes it’s dry on the outside but retains enough moisture to keep the virus alive, and only 1-10 is needed, apparently.
So, surfaces become carriers and not just ‘bodies’ which is the message being pushed 24/7 by the media and the government (but I repeat myself).
