Los Angeles County, the most populous county in the United States, reported Saturday a record single-day increase in confirmed COVID-19 cases since the summer surge in July, Trend reports citing Xinhua.
A total of 3,780 new cases and 20 new deaths were reported in the previous 24 hours, according to the Los Angeles County Department of Public Health.
"This marks the highest amount of positive cases in one day, not associated with a backlog of cases, since mid-July," said the department in a daily release, adding that the elevated number of cases reflects increased testing across the county.
Officials said that over 56,000 tests were processed on Friday, and the positivity rate remains high at almost 6 percent.
The department has identified 336,549 positive cases countywide and a total of 7,266 deaths to date.
There were 966 people currently hospitalized with COVID-19, and 28 percent of them are in the ICU, officials said, noting that current hospitalization "is the highest it has been in nearly two months."
Younger people continue to drive the increase in community transmission in the county. Over 74 percent of the new cases reported on Saturday are from people under 50 years of age, while 90 percent of reported deaths on the day are the over-50s.
Officials noted that the rise in cases complicates planning for increasing the numbers of students returning to schools, further re-opening additional sectors and permitting additional activities.
