Coronavirus antibody study suggests hundreds of thousands of LA County residents may have been infected – ABC7 Los Angeles
- LOS ANGELES (KABC) — An estimated 4.1 percent of adult residents in Los Angeles County have the antibody to the coronavirus, which indicates that hundreds of thousands of them may have been infected, according to preliminary results from a new study.The collaborative study from USC and the county’s department of public health suggests “infections from the new coronavirus are far more widespread than previously thought.” The study indicates that approximately 221,000 to 442,000 adults in the county have had the infection at some point in time. The results also suggest that the mortality rate is much lower.
That figure is 28 to 55 times bigger than the 7,994 confirmed COVID-19 cases in the county at the time of the study in early April, according to the study. As of Monday, there are 13,816 positive cases in the region.”These results indicate that many persons may have been unknowingly infected and at risk of transmitting the virus to others,” said Dr. Barbara Ferrer, county public health director.
- However, officials caution that testing positive for the antibodies does not mean a person is immune and that more research is needed.
- “The concern here is we don’t want the public to interpret these test results as, ‘Oh, I think I have immunity,’ because that question hasn’t been credibly, scientifically answered yet,” said Sood.
- Sood says even if you are antibody positive there’s no knowing how much immunity to the virus you have and how long that immunity will last.
- There will be a second round of tests done in the near future, which the doctors say will provide further clarity.
