LOS ANGELES (CNS) — While insisting that death rates are continuing to decrease overall, Los Angeles County reported nearly 60 more fatalities due to the coronavirus Wednesday, along with more than 2,400 new confirmed cases.

County public health director Barbara Ferrer said the 2,428 new cases announced Wednesday included about 700 that were part of a backlog of testing results at the state due to a breakdown in the statewide electronic reporting system. That backlog dated back about two weeks and stalled results of about 300,000 tests statewide.

The new cases reported by the county, along with 73 announced by health officials in Long Beach and 13 by Pasadena's health agency, increased the cumulative countywide total of cases confirmed since the start of the pandemic to 214,283.

Ferrer announced another 58 coronavirus deaths, although one of those fatalities was announced Tuesday by Long Beach. That city added three more deaths Wednesday. The county's cumulative total of coronavirus fatalities was 5,112 as of Wednesday afternoon.

About 92 percent of people who have died from the illness had underlying health conditions, a percentage that has remained constant throughout the pandemic. Ferrer noted that while that percentage is high, it still means that 8 percent of people had no health issues and still died from the disease.

"This disease can be devastating whether you have underlying health conditions or you don't," she said.

Ferrer again noted that younger residents continue to represent the bulk of new coronavirus cases. She said residents aged 18 to 49 represent more than 60 percent of all new cases, and they "are driving infections in Los Angeles County at this time."

She said the 18 to 29 age group has "the highest case rate among all age groups" in the county.

Residents between 30 and 65 represent roughly half of all hospitalizations in the county, while those 18 to 29 are about 9 percent to 10 percent of hospital patients.

Ferrer said there have been 1,278 cases to date among the county's homeless population, along with 139 among staffers at homeless shelters or transitional housing facilities. There have been 31 deaths among the homeless.

Ferrer said the county has seen success in its efforts to control the spread of the virus among the homeless, a group she called traditionally "at much higher risk of poor health outcomes from just about every disease." She attributed the relatively low numbers of cases and deaths among the homeless to the work of various agencies, saying the county "could have seen a higher rate of devastation if we hadn't had collaboration from the beginning."

As of Wednesday, there were 1,538 people hospitalized in the county due to coronavirus, with 32 percent of them in intensive care units and 19 percent on ventilators.

"We continue to see a declining trend in daily hospitalizations," Ferrer said.

As recently as about two weeks ago, daily hospitalizations were above 2,000.

The drop in hospitalization numbers and death rates has led health officials to express optimism about the success of efforts to control the spread of the virus. But the virus is still widespread. Ferrer noted Wednesday that COVID-19 still presents too much of a risk for colleges and universities to resume in-person classes, with very limited exceptions.

"But that's only for students who are or will become part of the essential workforce," she said. "And it's only for required activities that cannot be accomplished through virtual learning, this mostly is about labs and practicums. All other academic instruction must continue to be done via distance learning."

Health officials said the transmission rate of the illness has been dropping over the past two to three weeks, leading to the recent reduction in numbers of people hospitalized. Modeling by health officials showed as of Wednesday that about one of every eight county residents has been infected with the virus at some point, although many of those cases may have been asymptomatic, meaning the person never became ill or even aware of the infection.

Dr. Roger Lewis, director of demand-modeling for the county Department of Health Services, said current trends show that the county should have adequate hospital space for coronavirus cases over the next four weeks. He said that while the trends are all heading in the right direction, residents "must keep our practices up" to continue controlling the spread of the virus. He said there are still "many highly susceptible" residents in the county who could be easily infected and become seriously ill.
