A coronavirus antibody test conducted by Stanford University scientists concluded that the infection is both more common than previously thought and possesses a lower fatality rate than what current data suggest.

“Our data imply that, by April 1 (three days prior to the end of our survey) between 48,000 and 81,000 people had been infected in Santa Clara County. The reported number of confirmed positive cases in the county on April 1 was 956, 50-85-fold lower than the number of infections predicted by this study,” their study reads.
