A new study unveiled Monday from the University of Southern California (USC) with the Los Angeles County Department of Public Health discovered infections of the novel Wuhan coronavirus to be far more widespread with a lower fatality rate than initially thought.
The California researchers conducted rapid antibody testing of a representative sample of adults and found that approximately 2.8 to 5.6 percent of L.A. County’s adult population already had coronavirus antibodies present, translating to 221,000 to 442,000 past-infected people. The new estimate dwarfs the nearly 8,000 cases that had been reported at the time the study took place April 10-11. There are now nearly 14,000 confirmed cases of the virus and more than 600 deaths officially reported in the county as of this writing, according to L.A. County Department of Public Health.
“We haven’t known the true extent of COVID-19 infections in our community because we have only tested people with symptoms, and the availability of tests has been limited,” said the study’s lead investigator and USC Professor Neeraj Sood in a statement. “The estimates also suggest that we might have to recalibrate disease prediction models and rethink public health strategies.”
