4,015 additional coronavirus cases have been confirmed in Los Angeles County Tuesday, the largest one-day spike since March, in part, due to a backlog of cases, officials said. 

The backlog of about 2,000 test results received from one lab who just submitted lab results from July 2 through July 5, according to the Los Angeles County Department of Public Health (LADPH). 

The Santa Clarita Valley total is now 3,377 and the L.A. County total of cumulative coronavirus cases now stands at 120,539 as of Tuesday, according to the LADPH.

Health officials confirmed the highest number of new cases of COVID-19 reported in a day with 4,015 new cases. The high number of cases are, in part, due to a backlog of about 2,000 test results received from one lab who just submitted lab results from July 2 through July 5 today. 

A total of 1,969 people are currently hospitalized due to COVID-19 throughout L.A. County, LADPH Director Dr. Barbara Ferrer said. 

“Every single person we have lost to COVID-19 was someone’s parent, sibling, friend and neighbor,” said Ferrer. “Our actions have consequences and they affect real people in our community. Choosing to not practice physical distancing or objecting to wearing cloth face coverings when around others can be a life-altering decision. Everyone shares the collective responsibility to slow the spread of COVID-19 to prevent an overwhelming surge of COVID-19 to save lives.”

Testing results are available for over 1,213,000 individuals as of Tuesday, with a daily positivity rate of 11.6 percent, according to public health officials.

46 additional deaths have been reported Tuesday, for a total of 3,579 people who have died due to coronavirus in Los Angeles County.

Some local patients are tested multiple times, creating a discrepancy in the numbers, according to hospital officials.

There are 19 patients in the hospital as of July 1, while 110 patients have been discharged since the hospital’s first case was reported in March, according to Moody.
