Clinical morphology of the algorithm for diagnosing respiratory lesions in COVID 19

The new coronavirus SARS-CoV-2 is a single-stranded RNA-containing virus, belongs to the Coronaviridae family, belongs to the Beta-CoV B lineage. The virus is assigned to group II pathogenicity, as are some other representatives of this family (SARS-CoV virus, MERS-CoV). The SARS-CoV-2 coronavirus is presumably a recombinant virus between a bat coronavirus and an unknown coronavirus of unknown origin. The genetic sequence of SARS CoV-2 is at least 79% similar to the sequence of SARS-CoV. The article describes in detail and illustrates the features of upper respiratory tract lesions in COVID-19 patients identified during autopsies.
