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

DEATHS: Solano reported no new COVID-related deaths todayThe County has reported 42 COVID deaths just since Sept 1.  A total of 312 Solano residents have died of COVID or COVID-related causes over the course of the pandemic.

CASES: The County reported 75 new COVID cases over the last two days, 37 per day.  AGES: 11 of these 75 cases (15%) were youth and children under 18.  64% were age 18-49, 11% were age 50-64, and only 9% were 65+.

COMMUNITY TRANSMISSION RATE: Over the last 7 days, Solano has seen SUBSTANTIAL community transmission, with 406 new cases, down from 413 on Wednesday.  450 cases in 7 days would move Solano up into the CDC’s population-based definition of a HIGH transmission rate, and we would need to drop below 225 cases in 7 days to rate as having only MODERATE community transmission.

(CDC FORMULA: 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.  Reference: CDC’s “Level of SARS-CoV-2 Community Transmission”.]

ACTIVE CASES: Solano’s 397 ACTIVE cases is up slightly from Wednesday’s 396, and still far above our summer rates.

CURRENT hospitalizations were up today from 37 to 40 persons, and still far above the range we saw during last summer.

Ventilator Availability is up today from 46% to 52%, but still in the range of last winter’s surge.

TOTAL hospitalizations: Solano County’s TOTAL hospitalized over the course of the pandemic must be independently discovered in the County’s occasional update of hospitalizations by Age Group and by Race/Ethnicity.  The County updated its Hospitalizations charts today.  See below.  The differing race/ethnicity numbers indicate a number of persons whose race/ethnicity was not given or recorded.

FACE MASKS… Required for all in Benicia and Vallejo

Benicia City Council passed a citywide indoors mask mandate that went into effect on August 24 and includes everyone 4 years old and up when indoors in public places, even those of us who are vaccinated.  Benicia was joined by Vallejo on August 31.  In the Bay Area, Solano County REMAINS the only holdout against a mask mandate for public indoors spaces.

SOLANO COUNTY BOARD OF SUPERVISORS failed to consider an agendized proposal for a countywide MASK MANDATE on Tuesday, September 14.  Last week’s Bay Area news put Solano in a sad light: all other county health officers issued a joint statement offering details on when they would be able to lift mask mandates (not likely soon).  TV news anchors had to point out that Solano would not be considering such a move since our health officer had not been able to “justify” a mask mandate in the first place.  The Solano Board of Supervisors has joined with Dr. Bela Matyas in officially showing poor leadership on the COVID-19 pandemic.
