“In the beginning, our model for understanding this infection was to treat it like another respiratory virus like influenza,” said John Swartzberg, clinical professor emeritus of infectious diseases and vaccinology in the UC Berkeley-UCSF Joint Medical Program. “I think one of the most unfortunate and interesting things about this virus is that its interaction with us is actually far more complicated than that.”
"This virus is unusual and it's hard not to take a step back and not be impressed by how many manifestations it has on the human body" author of https://www.nature.com/articles/s41591-020-0968-3
