The coronavirus outbreak in Los Angeles County is thought to have actually contaminated a minimum of 200,000 individuals by early April, which would far surpass the number of officially verified cases, according to a report on Monday.

A large scale research study by the University of Southern California and the Los Angeles County Department of Public Health found that 4.1 percent of the county’s adult population has antibodies to the virus in their blood, which is a sign of past exposure.

Based on the county’s population, that means that between 221,000 and 442,000 grownups in the location have actually previously been infected, the study approximated.

” We haven’t known the real degree of COVID-19 infections in our community because we have just checked people with symptoms, and the availability of tests has been restricted,” said lead private investigator Neeraj Sood, professor of public policy at the USC Cost School for Public Law. “The price quotes also suggest that we may have to recalibrate disease forecast models and reconsider public health methods.”

The outcomes were identified from antibody screening of about 863 people who were representative of L.A. County, the researchers said, according to the L.A. Times.

The approximated infection numbers are 28 to 55 times greater than the 7,994 verified COVID-19 cases L.A. County had reported at the time of the research study in early April.

Barbara Ferrer, director of the L.A. County Department of Public Health, stated the results reveal that a big percentage of the population unknowingly had the virus and are “at threat of transmitting the virus to others.”

Due to the greater infection numbers, it likewise implies the death rate from the infection is much lower than originally believed.

” Though the results show a lower threat of death among those with infection than was formerly believed, the number of COVID-related deaths each day continues to mount, highlighting the requirement for continued energetic prevention and control efforts,” stated Paul Simon, primary science officer at the L.A. County Department of Public Health and co-lead on the research study.

A minimum of 615 coronavirus deaths have actually been confirmed in the county as of Tuesday morning, according to information from Johns Hopkins.

Scientists mean to duplicate the study every couple of weeks over numerous months in order to track the spread of the virus, the L.A. Times reported.
