Some people who know a lot about viruses, in other words not WHO, had this to say about COVID:
Most of us have already absorbed the idea that the coronavirus does some weird and sinister things to the human body that are unlike most other respiratory viruses known to man. But now a new study finds yet another unsettling thing that the virus appears to do to help spread from cell to cell.
A new study by an international team led by UC San Francisco finds that cells infected with SARS-CoV-2 quickly begin to grow new arms or dendrites — referred to clinically as filopodia — which are themselves studded with fresh virus particles. These filopodia then seek to reach into and through the walls of neighboring cells, thereby infecting them. And this appears to be a second mode that the virus has for replicating and spreading itself in the body. […]
Krogan says that while other viruses — including HIV and the family of viruses that cause smallpox — also use filopedia as mechanisms of spreading infection, the way this virus so rapidly prompts the growth of these tentacles is highly unusual. And the shape of them, branching off the cell and each other like trees, is also apparently strange.
But in COVID’s ‘enhanced’ ability to spread also lies its weakness.
