Los Angeles County reached a grim milestone this week, with COVID-19 deaths topping 1,000 (at press time), even as officials expressed optimism that stay-at-home orders could be loosened in the coming weeks.

The county Department of Public Health on Tuesday reported 59 more deaths due to the coronavirus, although six of those deaths were reported Monday by Long Beach and Pasadena, which both have their own municipal health agencies. Long Beach announced two additional deaths Tuesday afternoon, raising countywide fatality total to 1,002.

After announcing that the death toll had reached 1,000, county public health director Barbara Ferrer called it “an unfortunate milestone.’’

The fatalities also continued to have a disproportionate impact on the Black community. According to the county, of the 918 people who died for whom information was available, 37 percent were Latinx, 29 percent were White, 18 percent Asian, 14 percent were Black and 1 percent were Native Hawaiian/Pacific Islander. Black residents make up roughly 9 percent of the county’s overall population.

Of the people who have died, 462 were residents of institutional settings, the vast majority of them in nursing homes-representing 46 percent of all COVID-19 deaths in the county. Of the 11 health care workers who have died in the county during the pandemic, eight worked at nursing homes, Ferrer said. There have been a total of 4,488 cases among residents and staff in institutional settings, including nursing homes, skilled nursing facilities, assisted living facilities, shelters, jails and prisons, according to the county.

Coronavirus testing has been ramped up at nursing homes throughout the county, with tests being provided for all residents and staff regardless of whether they are showing any symptoms. Ferrer publicly apologized Monday for not offering such widespread testing from the outset of the pandemic, before it was known that people could transmit the virus to others without showing any symptoms of the illness.

The county also issued a revised order last week for nursing homes, barring all non-essential visitors and allowing only essential workers to enter. The order also suspends all communal dining and other activities and requires staff to wear masks and protective equipment, and mandating that residents wear some type of face covering any times they are outside their own room.

The county also announced 597 additional coronavirus cases Tuesday, while Long Beach added 20 more, raising the countywide total to 20,996.

Despite the continued increase in numbers of cases and deaths across the state, Gov. Gavin Newsom on Tuesday expressed optimism that it could be “weeks, not months’’ until some of the stay-at-home orders are relaxed, possibly allowing some lower-risk businesses to reopen.

Ferrer said she shared that hope. The county’s Safer At Home order is currently scheduled to expire May 15.

“I think we’re all with the governor on this,’’ Ferrer said. “… We know that we’re headed into recovery. We’re hoping that happens sometime in the middle of May, that’s our best guess right now.’’
