San Francisco May Have Reached Herd Immunity

The Guardian: “San Francisco is still recording a small number of coronavirus cases, about 13.7 per day… but they don’t appear to be gaining enough of a foothold in the population to trigger wider outbreaks.”

Said Dr. George Rutherford, professor of epidemiology at University of California: “That is what herd immunity looks like. You’re going to have single cases, but they’re not going to propagate out.”
