There is no chance a virus infects a cell through transmission by synapsis, ZERO.
That comment by falconer is the WORST comment from him that I have ever read on this board.
Study a little about how viruses infect cells, and you will understand the process, which is well understood, and it is not by electrical transmission down a nerve path.
Show me anything scientific besides "there is a poney in here somewhere" that you contend is the scientific basis for a 1% chance this could happen.
Viruses enter cells in capsids and synapsises don't have the capability to transfer capsids. Period.
