California Delta surge pushes COVID hospitalizations to highest since April – .



With the now-dominant delta variant still on the rise in California, COVID-19-related hospitalizations are also on the rise, surpassing thresholds in the Bay Area and state that have not been seen since the spring.

On Monday, confirmed hospitalizations for COVID-19 in California crossed the 2,000 mark – with more than 500 of those patients in intensive care units – for the first time since early April, state data showed. Meanwhile, the Bay Area surpassed 300 hospitalizations for the first time since early April and surpassed 100 intensive care admissions on Tuesday for the first time since late March.

As of Tuesday, 61% of California residents were fully vaccinated against COVID-19, and evidence so far shows that the vaccines offer strong protection against the delta variant. In the United States, unvaccinated people account for 97% of COVID hospitalizations and 99% of deaths, according to the CDC. Bay Area hospitals are also reporting that most COVID-19 admissions are from patients who are not fully immunized.

But the cases have increased rapidly. On Monday, the state reported more than 7,600 new cases, the first time that number has exceeded 7,000 since early February.

Recorded cases are often highest on Mondays as California Department of Public Health data collection catches up on weekends. But Monday’s number was still just a quarter of the state’s pandemic peak in early January of more than 28,000.

At that time, at the height of the winter wave, hospitalizations reached nearly 22,000, overwhelming health facilities across the state. Available ICU capacity has dropped to 0.7% in the Bay Area and to 0% in the San Joaquin Valley and Southern California.

Currently, the state’s positive test rate – reflecting the 7-day average percentage of tests that come back positive – is 4.2%, the highest since mid-February. Just two weeks ago, that number was 1.7%, and the rate is currently six times higher than the pandemic low of 0.7% on June 7.

The rate is also rapidly moving towards the 5% level – one of the CDC’s two benchmarks that would take California from a “low” level of community transmission to a “moderate” level. The CDC’s other indicator for moderate transmission is a rate of 10 or more total new coronavirus cases per 100,000 people in the past 7 days. California’s case rate was 7.7 per 100,000 on Sunday, down from just 2 per 100,000 on June 1.


Among the Bay Area counties, Sonoma reported the highest hospitalization rate of 10.9 per 100,000 people on Sunday, down slightly from a recent high of 12.5 on July 7. The last time the county had a rate above 10 was on February 24, with a high of 26.5 on January 7.

Solano County had the second highest hospitalization rate in the Bay Area of ​​8 per 100,000 on July 18, double the rate from two weeks ago. The last time the rate was above 8 was on April 25, when there were 9.2 cases per 100,000. The county’s hospitalization rate peaked at 50.7 per 100,000 on the 10th. January.

San Francisco’s most recent hospitalization rate was the fifth highest in the Bay Area, at 6.1 per 100,000 on Sunday. The rate quickly doubled from 3.1 on July 12. San Francisco had not seen a rate above 6 since March 20, when it was 6.5. The city peaked at 36.5 hospitalizations per 100,000 on January 12.

Marin County on Sunday recorded the lowest hospitalization rate in the Bay Area, at just 1.5. But the county reached nearly 4 hospitalizations per 100,000 on July 8, a level it had not reached since the end of April. Marin was the only Bay Area county to record multiple days with a hospitalization rate of 0 from mid-June to the end of June. Its pandemic peak was 17.8 per 100,000, reached on January 6.

Marin County has one of the highest COVID-19 vaccination rates in the country, with 85.2% of eligible recipients fully vaccinated and 92.4% having received at least one dose.
