they have electron microscope images

but they didn't isolate a virus and prove it was contagious prior to taking the image

so we have no basis to conclude that the thing shown is a contagious virus
 
(probably they are cell breakdown products from the cells they "culture" the "virus" in) 

 What they present as a virus are just protein cells, there are no electron images of viruses, the magnification is not enough. They Show a protein cell and say usually that the protein cells contain viruses, but no virus image of a virus itself . All CGI.
