This ties in with my previous post regarding Ian Lipkin and the difficulty
of understanding cause and effect. The idea that the virus isn't actually
spread by the mite is a non-starter. We all know that in severe mite
infestations one of the most obvious indicators is deformed wings. Whether
the mites transmit the virus is moot. They do something to the colony to
ruin it. At the very least it appears that they weaken the bees' ability to
ward off infections on their own.

provokes constant stimulation of the protective system and in the course of
time parasites can weaken it greatly.
