L.A. County Study: Coronavirus Outbreak Up to 55 Times More Widespread, Less Deadly than Predicted
The novel coronavirus has infected roughly 4.1 percent of the population in California’s Los Angeles County, suggesting the region’s outbreak is far more widespread than previously thought, between 28 and 55 times higher than the number of confirmed cases, new research shows, echoing the findings of a similar study elsewhere in the state.
However, the new data, if accurate, also indicates that the coronavirus death rate in L.A. County, the most populous in the country, is lower than initially predicted.
Researchers from the University of Southern California (USC) and the L.A. Department of Public Health gleaned the data from antibody testing of about 863 county residents. Antibodies are an indication that an individual’s immune system has responded to a past infection.
On Monday, CNBC reported:
USC and the health department released preliminary study results that found that roughly 4.1% of the county’s adult population has antibodies to the coronavirus, estimating that between 221,000 adults to 442,000 adults in the county have had the infection.
This new estimate is 28 to 55 times higher than the 7,994 confirmed cases of Covid-19 [coronavirus illness] reported to the county in early April. The number of coronavirus-related deaths in the county has now surpassed 600, according to the Department of Public Health. The data, if correct, would mean that the county’s fatality rate is lower than originally thought.
If accurate, the top end of the estimated number of L.A. County residents who may have contracted the virus would amount to more than half (56 percent) of the total number of cases in the United States, while the lower range would equal to about 30 percent of the overall number in America.
Stanford University researchers who looked at California’s Santa Clara County, much less populated than its L.A. counterpart, reached similar conclusions, finding that the coronavirus outbreak may be more widespread but less deadly than originally estimated.
The Stanford University researchers found that between 2.5 percent and 4.2 percent of county residents had antibodies to the coronavirus by early April, the Los Angeles Times reported on Friday, adding:
Though the county had reported roughly 1,000 cases in early April, the Stanford researchers estimate the actual number was between 48,000 and 81,000, or 50 to 85 times greater.
…
Based on their results, the Stanford researchers estimated the mortality rate in Santa Clara County to be between 0.12% and 0.2%. By comparison, the average death rate of the seasonal flu is 0.1%.
The findings of both the L.A. and Santa Clara studies echo the results of other assessments.
Earlier this month, the Economist magazine cited a new study that found the fatal and highly contagious novel coronavirus has spread faster but is less deadly than official data imply.
The coronavirus mortality rate could be as low as 0.1 percent, “similar to that of flu,” the researchers cited by the Economist found, noting that the faster the disease spreads and hits its peak, the fewer people will die.
In early March, Dr. Anthony Fauci, the director of the U.S. National Institute of Allergy and Infectious Diseases and member of the White House Coronavirus Taskforce, predicted a much higher death rate for the United States, saying it could reach two percent.
