"SARS-CoV-2 belongs to the Betacoronavirus genus of the family Coronaviridae. This genus also includes the human respiratory pathogens SARS-CoV-1, Middle East respiratory syndrome (MERS) coronavirus (MERS-CoV), human coronavirus (HCoV)-HKU1, and HCoV-OC43 [14]. Together with the closely related bat coronavirus RaTG13 and SARS-CoV-1, SARS-CoV-2 is classified as a member of the Sarbecovirus subgenus of SARS-related coronaviruses [15]. Rapid characterization of SARS-CoV-2 by electron microscopy and NGS confirmed that it shared the structural features and genomic organization of other betacoronaviruses [6, 7]. It is a pleomorphic enveloped virus (size range: 60–140 nm) studded with distinctive surface spikes"

"Royal Rife was not alone in maintaining that microorganisms arose from within the body and could change form from viruses, to bacteria and yeasts - a theory known as pleomorphism"

"Rife was able to observe and prove the reality of pleomorphism. He was able to do this partly because of his advancements with optics, but also because he used light frequencies to highlight his samples rather than chemical dyes. Using dyes kills the specimen, so tissues cannot be viewed in the natural living state. Studying dead samples is a dumb as studying cadavers to understand living processes. Further, Rife was able to isolate the particular viral form involved in all forms of Cancer, and discover a frequency signal that would neutralize it."
