so it keeps your hemoglobin count up, and prevents complement from destroying a cell. Also inhibits locomotion of neutrophils and eosinophils. So it seems that by these mechanisms its likely that coronavirus moves around ur body by way of the immune system. If they need to hop a ride on neutrophils and eosinophils they cant infect other cells. If the virus cant lyse a cell after reproducing, the virus cant get out and it will eventually degrade by regular apoptosis. This is all my theory.
