Review of COVID-19 Paper Methods: Sequencing the "Virus"

In this video I go over the main COVID-19 "virus" isolation paper's methods on the techniques used in sequencing this "new virus". The first step in sequencing the "virus" is assuming that the RNA found in the patient airway fluid samples and cell culture supernatants somehow belong to a "virus". After this assumption, a combination of Illumina sequencing and nanopore sequencing were used to somehow produce a "virus genome". After this, PCR tests were designed with specific primers to test for this new "virus". The "virus" sequences were then compared with reference sequences. And finally, statistical analysis was performed on determining the likely evolutionary history of the "virus" genome. Essentially, the paper outlines a lot of obscure computer and statistical techniques to form long genetic sequences from RNA assumed to be from a "virus". Truly bizarre "science"...
