Los Angeles recorded its highest number of daily new COVID-19 infections ever on Thursday, according to L.A. County Health Officer Dr. Muntu Davis. The previous high was Wednesday, at just under 4,000. Before that, you have to go back to July.

Davis said that the average number of cases over the past 2 days was 4,500. That exceeds the emergency threshold set by L.A. County Director of Public Health, Barbara Ferrer recently. If cases average 4,500 or more for 5 days straight, Ferrer said the county would implement another Safer-at-Home shutdown, as it did in the spring.

“Potentially by Sunday,” said Davis, “We would need to implement that Safer at Home Order.”

Ferrer said on Wednesday the county was averaging about 1,100 new cases a day on November 1. That figure rose to almost 2,000 one week later. Ferrer, said the total of new infections reported Wednesday was 3,944.

Ferrer then warned that, if L.A. didn’t act drastically to reduce transmission, daily cases may hit “more than 4000 a day” by early December. That seems an understatement, given Wednesday’s number was nearly there.

Additionally Dr. Christina Ferrer, who oversees L.A. County hospitals said the R Effective or the rate at which new people are infected, is now 1.18. That is the highest since the country in June recorded an R Effective of 1.26. At over 1, it means that every new patient is going on to infect more than one additional person. In a county of 10 million, even that small number over 1 can mean huge growth.

The 7-day test positivity rate has risen from 3.1% on November 1, 5.8 on November 8 and 7.1% today. That’s even as the county has increased testing from around 40,000 a day in early October to about 65,000 a day this week.

“There’s a silver lining here,” said Ferrer. “Clinicians and physicians have learned how to better treat the virus.” That means, she said fewer people who are hospitalized with the virus are dying.

But, she warned, if hospitals and ICUs are overwhelmed, COVID-19 patients will go untreated and a greater number of them will die. “If our case rates keep going up and our hospitalization rate is higher than July, there is no way we can keep up.”

“I don’t think it’s inevitable that we get there,” said Ferrer. “The hope is we do every single thing that we can. We’re a little behind, to be honest. This has been a community that has rallied before.”

Dr. Christina Ghaly, who oversees hospitals in L.A., said that there has been a “significant increase in new patients in hospitals” in the past week. In September, there were about 100 new COVID cases a day. Now, she said, it’s “closer to 200 a day.” Ghaly warned that an increase in hospitalizations is almost inevitable in the next two weeks, given the currenet number of new cases and the virus’s incubation period.

Currently there are about 1200 people in L.A. hospitals with COVID, she said. “Half of of those are in ICU,” observed Ghaly. “Two thirds of those are on a ventilators. One half of those will die,” she said, “based on previous experience.”

Ghaly indicated that “It is highly likely that will will experience the highest rate of hospitalizations we have seen in the COVID1-9 pandemic to date in the next month.” If trends continue as they are she said, “demand for ICUs will outstrip the supply of beds.”

Hospital beds can be surged and that is happening, she explained. Likewise ICU beds. But, the “primary limiting factor is the availability of staff who are highly trained in an ICU environment, and that is not easy to come by.” It takes months (and money) to train an ICU nurse.

Ferrer indicated that the total number of new daily deaths related to the virus was 36.

The numbers come just one day after Ferrer announced increased restrictions on businesses across the county in an attempt to curb social spreading of the virus.
