Since we know that the coronavirus is being spread by Mercenary Army Program (MAP) victims, could it be that the actual virus is not visible in any case, and what science perceives through study are the effects, not the virus? Could viruses be seeded in the etheric plane, or masked in some way?

This is not the case. These are viruses quite similar to prior organisms that have come along. They are laboratory created with an intention to optimize them with respect to their various properties that will make them a good candidate in causing a pandemic in this case, and this is very much the profile, that it has a high rate of infectivity and unusual characteristics that will largely be unappreciated for at least some time and that will add to the worries and be a double liability. So the overall consequences will be that much worse and the fear that much greater.
