A Synthesis of Discovery About SarsCov-2 in the USA Jon Boone Revision - August 23, 2020 SarsCov-2 “is really two different diseases. In the first few days, it is like a very bad cold. In some people, it then morphs into pneumonia, which can be life threatening. What I found is that treatments for the cold don’t work well for the pneumonia, and vice versa.”—Dr. Harvey A. Risch, Yale University A virus is a nearly infinitesimal mote of DNA encased in a protein shell. Scientists have grouped the many varieties into cladistic relationships that consider size, shape, topology, and behavior, among others. There are seven known coronaviruses that infect humanity; the first was discovered in 1931 and subsequently tied to human infections in the 1960s. SarsCov-2 is the latest strain. But given its close physical and behavioral similarities to other members of its single-stranded RNA family, it is not that mysterious. Like all viruses, it requires a host cell to reproduce. The virus invades the cell and commandeers its reproductive system to churn out cascades of progeny, which can then destroy the host and spread throughout the organism, often with mortal consequences unless that organism has an immune response sufficient to quell the viral invasion. Sars-Cov-2 is one-tenth the size of a micron; that is, a single virion is one tenth of a millionth of a meter. A cluster of a hundred on an aerolized droplet a few tenths of a micron in diameter can pass through almost any filter. Even one virion, which takes only minutes to become over 200 in a host cell, can soon impart a lethal dose of disease. Confounding Treatments, Confusing Numbers In a population of 330 million, at least one half of the approximately 150,000 deaths in the United States attributed to SarsCov-2 is skewed—for three entwined reasons. First, during the initial pandemic phase in February and March, many physicians misunderstood the nature of the illness. This new strain of coronavirus tricks the immune system so that the latter produces out of control inflammatory responses, which for many results in damaged lungs leading to severe pneumonia, fibrosis, and often deadly blood clots. However, since its first symptoms manifest as a cold, this led to treatment protocols that often made the infection worse. Doctors did not at first realize that the cold symptoms masked the real problem, uncontrolled inflammation; with better understanding, they 1
