The Origin of Contagious Disease Theory

Stefan Lanka has years of post graduate studying as a professional in several branches of biological sciences. He is a virologist and has proved there is such a thing as a virus. However the relation between a virus and cells is symbiotic not disease causing. He has been debunking the myth of virus as a contagious disease since 2008. He has done this by explaining that in order for the contagious virus theory to be correct the virus must be able to function as a separate living organism. This is an obvious fact. Further if a virus could spread as the theory states then certain abilities must exist in the contagious virus.
A virus must have many complex structures within a protected shell which allow it to: 1. Survive out side the body 2. Sense when it is in contact with a suitable host. 3. Regulate itself to then pierce that host cell's membrane and 4. Have energy to inject a self replicating strand of RNA/DNA which will then take over all the host cell functions.
These complex functions of life (requires respiration), sensing, attachment, release of stored energy (muscle or spring like functions require energy from respiration to compress the spring!) in a featureless tiny size defy chemistry, biology and physics!
He pointed out that in all the electron micrographs of supposed viruses not one has been separate from a cell and has had any of the required structures to function as claimed.
