Thanks. I don’t understand it at all
Does this mean that we should eat more protein or less protein?
Or doesn’t diet have anything to do with it?
Those proteins are what form the virus, and that is how it does its job to kill us.
A virus is not technically alive, it requires a living cell to replicate. The photos you have seen that look like a golf ball covered in mushrooms are the actual virus - those mushrooms are the binding proteins on the exterior. The ball is actually a bubble of fat, with the instruction proteins inside the ball.
Hand washing is important, as soap in water dissolves the fat bubble, killing the virus.
