SANTA ANA (CNS) — Fifteen more people have succumbed to COVID-19 in Orange County, hiking the death toll to 912, and officials also reported 335 new cases of coronavirus Tuesday, raising the cumulative total to 46,642. 

Of the deaths reported Tuesday, three were skilled nursing facility residents and two lived in assisted living facilities. Of the total death toll, 347 were skilled nursing facility residents and 56 lived in assisted living facilities.

Dr. Clayton Chau, the county's interim chief health officer and director of the Orange County Health Care Agency, told the Board of Supervisors on Tuesday that he was "optimistically confident" that the county will remain off the state's watch list.

Orange County was removed from the list Sunday. The state mandates a county must be off the list for 15 days before all schools can reopen.

Supervisor Lisa Bartlett said coming off the state's watch list does not mean the state will also reopen various businesses for indoor commerce such as personal services, shopping malls, restaurants and bars.

"I think it's important to clarify what that means, because a lot of individuals and businesses think that once we get through this 14-day wait period that we can open everything up again," she said.

"The only sector that can reopen is the schools," Chau replied.

But Chau said he is "hopeful" the state will issue new guidelines soon to reopen some of the closed businesses.

"There's a conversation between the state health officer and all the other county health officers on how do we reopen the other business sectors safely," he said.

Orange County Supervisor Don Wagner questioned why "If it's OK to reopen the schools, why can't we get some of the other sectors reopened."

Chau said it was a "pleasant surprise" that many counties on the state's watch list have been trending in the right direction.

"The cycle is happening a bit quicker than we expected it, which is good, and, so I don't think we were prepared to have that conversation of when the county was getting off the monitoring list," Chau said. "So what we don't want to repeat is the same mistake we did in May where we're reopening a whole bunch of businesses and then causing a large transmission."

Wagner said he was "a little surprised that schools will be paving the way when there are so many other sectors that are really hurting. But the governor will do what the governor will do and logic be damned."

The decision to reopen schools will be left up to each of the county's school districts.

Meanwhile, 39 elementary schools in the county have won approval for waivers to reopen for in-classroom learning, Chau said. That includes the six in Los Alamitos School District and the rest are private, he added.

Chau noted that while overall the county is doing well enough to get off the state's watch list, there are still some ZIP codes that have positivity rates as high as 17 percent to 21 percent.

Orange County could be placed back on the watch list should it be flagged for exceeding any one of six different metrics for three consecutive days. Those metrics are the case rate, the percentage of positive tests, the average number of tests a county is able to perform daily, changes in the number of hospitalized patients and the percentage of ventilators and intensive care beds available.

The county's data on hospitalizations and other key metrics have been moving in the right direction, with the rate of county residents testing positive for COVID-19 at 5.3 percent, below the state's desired threshold of 8 percent.

Hospitalizations edged down from 388 Monday to 385, with the number of intensive care unit patients decreasing from 116 to 113.

The county's case rate per 100,000 residents dropped from 85.1 to 83.3, which is still far higher than the California Department of Public Health threshold of 25 per 100,000 residents. 

The county has 33 percent of intensive care unit beds available, which is better than the state's 20 percent threshold. And the county's hospitals have 58 percent of their ventilators available, well above the state standard of 25 percent.

The change in three-day average of hospitalized patients stands at - 3 percent, much lower than the 10 percent state standard.

The OCHCA reported that 605,495 COVID-19 tests have been conducted, including 8,108 reported on Monday. There have been 38,450 documented recoveries.

And a new "super site" for COVID-19 testing like the one at Anaheim Convention Center will open Wednesday at the Orange County Fairgrounds in Costa Mesa, officials announced Tuesday.
