Nobody has ever demonstrated any virus to exist by physical separation and genetic identification despite the technology being available to do so. Virologists use smoke and mirrors by performing cultures of samples from patients and then claim that the cells that die in the culture are caused by a particle they claim to be a virus which has never been isolated to prove it actually does so. It should also be noted that Dr Stefan Lanka has proven that the process of Performing the cultures without adding the supposed virus kills the cells in the culture. In other words, the control culture without the supposed offending virus or sample produces the same result.
