MORE: The first large-scale community test of 3,300 people in Santa Clara County found that 2.5 to 4.2% of those tested were positive for antibodies—a number suggesting a far higher past infection rate than the official count. abcn.ws/3ajgWcO
Based on initial data, researchers estimate the range of people who may have had the virus to be between 48,000 and 81,000 in the county of 2 million—as opposed to the approximately 1,000 in the county's official tally at the time the samples were taken. abcn.ws/3ajgWcO
“Our findings suggest that there is somewhere between 50 and 80-fold more infections in our county than what’s known by the number of cases than are reported by our department of public health," the study's leader tells @DianeSawyer. abcn.ws/3ajgWcO
