Benicia still registering above CDC’s measure for HIGH TRANSMISSION of COVID-19


Data shows a dip in 7-day COVID case numbers in Benicia, but transmission level still HIGH

By Roger Straw, September 11, 2021

Over the last 7 days, the number of newly reported COVID infections in Benicia fell from an astonishingly high 105 to 43.  This is good news, but Benicia remains substantially over the CDC’s definition of a HIGH level of transmission.

Based on Benicia’s population of roughly 28,000, when Solano County reports 14 or more new Benicia cases over the last 7 days (the red line in the graph above), the CDC classifies us as having a level of “SUBSTANTIAL transmission.”  If we see 28 new cases over the last 7 days (the purple line) we are in an area of “HIGH transmission.” That’s where we were at the County’s most recent report on Friday, with 43 total new cases over the last 7 days.

Benicia entered into substantial transmission on July 12, and high transmission on July 23, with numbers increasing until last Wednesday, September 8.

The daily data is shown in the chart above and also in the table below.

Note that Solano County’s reporting is often tardy, based on tardy reporting from hospitals and the State.  So the massive rise in outbreaks we saw on September 1 could be off some.  But the CDC’s 7-day formula is helpful in mitigating the delays in reporting, similar to taking an average.  Our numbers continue to be at least in the Substantial range, and the numbers are clear evidence of Benicia’s continuing delta surge.

ICU beds in Solano County now in red warning zone


By Roger Straw, Wednesday, September 8, 2021

Wednesday, September 8: Solano reports 406 new infections and only 9% of ICU beds available (red warning zone)

Solano County COVID dashboard SUMMARY:
[Sources: see below.]

DEATHS: Good news, no new deaths were reported over the 5-day holiday hiatusTotal Solano deaths over the course of the pandemic remain at 276.

CASES: The County reported  406 new COVID cases in the last five days, 81 per day, down significantly from last week, but still in the range of last winter’s surge.

COMMUNITY TRANSMISSION RATE: Over the last 7 days, Solano has seen 1,967 new cases, OVER FOUR TIMES the CDC’s definition of a HIGH rate of transmission.  Based on Solano County population of 449,432, the CDC would rate us in “SUBSTANTIAL” transmission with 225 cases over the last 7 days.  Double that, or 450 cases in the last 7 days would rank us in “HIGH” transmission.  And we are at 1,967 cases as of today!  [Reference: CDC’s level for “High Community Transmission”.]

YOUTH CASES: Case numbers continue to show a startling increase in the percentage of new cases among young persons age 0-17, increasing another tenth of a percent today to a new high of 13.9% of total cases.  The percentage of youth cases increased very, very slowly over the course of the pandemic, starting below 6%, and only gradually reaching 12% in mid-April of 2021.  The percentage of youth cases has jumped a full 0.9% since mid-August.

ACTIVE CASES: Solano’s 813 ACTIVE cases is down sharply from last Friday’s 1,051, but still alarmingly up from 212 on July 2, and in the range we experienced during the deadly surge last winter.

POSITIVE TEST RATE:  Our 7-day average percent positivity rate was 11.7% today, down from 13.9% on last Friday, but 3.5 times today’s California rate of 3.3% and 1.25 times today’s U.S. rate of 9.4%[Source: Johns Hopkins]  WARNING: The Delta Variant is here in Solano County and spreading fast.  Time to mask up again – watch out and take care!  

HOSPITALIZATIONS:

CURRENT hospitalizations were down today from 123 to 112 persons, but still in the range we saw during the winter surge.

ICU Bed Availability dropped alarmingly to only 9% of ICU beds available today, in the RED WARNING ZONE.  This is the first time Solano ICU beds were in the red zone since January 27, 2021.

Ventilator Availability was up today from 44% to 51%, but still in the range of last February’s winter surge.

TOTAL hospitalizations  The County’s Monday-Friday dashboard shows an intake/discharge total of CURRENTLY hospitalized cases (above), but never reports on the TOTAL hospitalized over the course of the pandemic.  That total must be independently discovered in the County’s occasional update of the Hospitalizations by Age Group chart.  The County updated its Hospitalizations charts today.  See the Age Group chart and the Race / Ethnicity chart below.  Interestingly, the race/ethnicity numbers don’t square with the age group numbers.

FACE MASKS… Good News in Benicia and Vallejo

GOOD NEWS!  Benicia City Council passed a citywide indoors mask mandate. The mandate went into effect immediately and includes everyone 4 years old and up when indoors in public places, even those of us who are vaccinated.  The mask resolution, press release, and a flyer now appear on the City website.

Benicia was the first Solano city to take action despite the County’s lack of strong guidance on masks.  Benicia was joined by Vallejo on August 31In the Bay Area, Solano County REMAINS the only holdout against even RECOMMENDING masks in public indoors spaces.  Hopefully, Dr. Matyas will learn from Benicia and Vallejo, and make the necessary difficult decisions, but all reports are that he intends not to do so. 

Please mask indoors in public places now, and maybe even indoors in crowded gatherings at home with vaccinated family and friends!  PLEASE talk to anyone you know who isn’t vaccinated.  This thing ain’t over yet!

Cases by City on Wednesday, September 8:
  • Benicia added 9 new cases today, a total of 1,354 cases since the outbreak began.  Benicia has seen 78 new cases over the last 7 days, nearly 3 times the CDC’s definition of HIGH community transmission level based on Benicia population.  [Note that Solano County is also rated in high transmission, and Solano’s 6 other cities are likely also individually experiencing high transmission.]

YOUTH CASES: Case numbers also show a startling increase in the percentage of new cases among young persons age 0-17, increasing another tenth of a percent today to a new high of 13.8% of total cases.  That doesn’t sound like much until you consider that the percentage of youth cases increased very, very slowly over the course of the pandemic, starting below 6%, and only gradually reaching 12% in mid-April of 2021.  The percentage of youth cases has jumped a full 0.8% since mid-August.

Ventilator Availability was down today from 51% to 44%, our lowest level since January 28, 2021 and the first time we’ve tipped below 50% since Jan. 29.

TOTAL hospitalizations  The County’s Monday-Friday dashboard shows an intake/discharge total of CURRENTLY hospitalized cases (above), but never reports on the TOTAL hospitalized over the course of the pandemic.  That total must be independently discovered in the County’s occasional update of the Hospitalizations by Age Group chart.  The County did not update its Hospitalizations charts today, so our TOTAL hospitalized since the outbreak started at 2,107. 

FACE MASKS… Good News in Benicia

GOOD NEWS!  Last week, Benicia City Council passed a citywide indoors mask mandate. The Council heard opposition from Dr. Bela Matyas, and support from Dr. Bonnie Hamilton.  The public spoke almost entirely in favor of a mandate and included a number of medical professionals.  Councilmembers debated on various finer points, and passed the resolution on a 5-0 vote. The mandate went into effect immediately. Everyone 4 years old and up must now wear a mask indoors in public places, even those of us who are vaccinated.  The mask resolution, press release, and a flyer now appear on the City website.

Benicia was the first Solano city to take action despite the County’s lack of strong guidance on masks.  Benicia was joined by Vallejo on August 31In the Bay Area, Solano County REMAINS the only holdout against even RECOMMENDING masks in public indoors spaces.  Hopefully, Dr. Matyas will learn from Benicia and Vallejo, and make the necessary difficult decisions, but all reports are that he intends not to do so.

Solano reports another 3 deaths and a remarkable increase in COVID case numbers


By Roger Straw, Wednesday, September 1, 2021

Wednesday, September 1: Solano reports 1,044 new infections, 3 more deaths, soaring community transmission levels.

7-DAY CASE RATE: Over the last 7 days, Solano has seen 2,192 new cases, substantially over the CDC’s level for “High Community Transmission”.  Based on Solano County population of 449,432, the CDC would rate us in “Substantial” transmission with only 225 cases over the last 7 days.  Double that, or 450 cases in the last 7 days would rank us in “High” transmission.  Solano County’s 2,192 cases is NEARLY FIVE TIMES the CDC’s High rate of transmission!

YOUTH CASES: Case numbers also show a startling increase in the percentage of new cases among young persons age 0-17, increasing another two tenths of a percent to a new high of 13.7% of total cases.  That doesn’t sound like much until you consider that the percentage of youth cases increased very, very slowly over the course of the pandemic, starting below 6%, and only gradually reaching 12% in mid-April of 2021.  The percent of youth has jumped a full 0.7% since mid-August.
