[For a complete archive of day by day data, see my Excel ARCHIVE – R.S.]

Tuesday, September 1: 35 new cases today, no new deaths.  Since the outbreak started: 5,547 cases, 47 deaths.Compare previous report, Monday August 31:Summary

  • Solano County reported 35 new cases today, total of 5,547 cases since the outbreak started.  Over the last 2 weeks, Solano reported 676 new cases, an average of 48 per day.
  • Deaths – no new deaths today, total of 47 Solano deaths.
  • Active cases – Solano reported 27 fewer ACTIVE cases today, total of 311.  Note that only 28 of these 311 people are hospitalized, so there are a lot of infected folks out among us, hopefully quarantined.  Is the County equipped to contact trace so many infected persons?  Who knows?  To my knowledge, Solano County has no reporting on contact tracing.
  • Hospitalizations – the number of currently hospitalized persons included 2 fewer today, total of 28.  The total number hospitalized since the outbreak started increased by 3, total of 282.  (Note that the County no longer reports Total Hospitalized, but we can add the new hospitalization numbers in the Age Group report – see below.)  Concluding a fifth week now, the County offers no information about availability of ICU beds and ventilators.
  • Testing – The County reports today that 939 more residents were tested today, new total of 75,559.  Solano has a long way to go: only 16.9% of Solano County’s 447,643 residents (2019) have been tested.

Positive Test Rate

Solano County reported today that our 7-day average test rate rose today, from 6.8% to 7.3%, our highest rate since we peaked at 9.3% on July 22.  Over the past week the daily rate change was +0.8%,  -1.3%, +1.0%, -1.0%, +0.7%, +0.4% and today’s +0.5%.  I find some of these daily fluctuations improbable.  7-day averages don’t normally jump like this – they are designed to “smooth out” the volatility of a daily data chart.  What is going on here?  The County reported a 7-day test rate low of 4.1% on August 11, and the County’s rate peaked at 9.3% on July 22.  Not really a smooth ride!  Health officials and news reports focus on percent positive test rates as one of the best metrics for measuring the spread of the virus.  The California 7-day test rate remained steady today at 4.9%(Note that Solano County displays past weeks and months in a 7-day test positivity curve chart which also shows daily results.  However, the chart does not display an accurate number of cases for the most recent days, as there is a lag time in receiving test results.  The 7-day curve also lags behind current unknown results.) 

By Age Group

  • Youth 17 and under – 6 new cases today, total of 613 cases.  No new hospitalizations among this age group, a total of 5 hospitalizations since the outbreak began.  Thankfully, no deathsIt is clear that our young people are catching the disease, with a recent increase in hospitalizations.  It seems too many youth are ignoring public health orders.  Cases among Solano youth have risen steadily over the summer, from 5.6% of total cases on June 8 to 10.9% most recently, and to over 11% yesterday and today.  Youth are 22% of Solano’s general population, so this 11% may seem low.  The significance is: 1) that youth numbers are increasing steadily and at a faster rate than the other age groups, and 2) that youth are seriously NOT immune – in fact 5 youth have been hospitalized.
  • Persons 18-49 years of age – 22 new cases today, total of 3,364 cases. This age group is 41% of the population in Solano, but represents 60.6% of the 5,547 total cases, by far the highest percentage of all age groups.  The County reported no new hospitalizations in this age group today, total of 92 hospitalized since the outbreak began.  No new deaths among this age group today, total of 4 deaths.  This age group is very active.  Some are surely ignoring public health orders, and many are providing essential services among us.  I expect his group is a major factor in the spread of the virus.
  • Persons 50-64 years of age – 3 new cases today, total of 1,060 cases.  This age group represents 19.1% of the 5,547 total cases1 new hospitalization, total of 76 hospitalized since the outbreak began.  No new deaths  in this age group today, a total of 7 deaths.
  • Persons 65 years or older – 4 new cases today, total of 509 cases, representing 9.2% of the 5,547 total cases2 new hospitalizations today, total of 109 hospitalized since the outbreak began.  In this older age group, 21.4% of cases required hospitalization at one time.  This is a much higher percentage than in the lower age groups.  No new deaths were reported in this age group today, total of 36 deaths.  This group accounts for 36 of the 47 deaths, or 77%.

Hospitalization rate by Race / Ethnicity

The County report on race / ethnicity includes case numbers, hospitalizations, deaths and Solano population statistics.  Today I am again featuring the tab that shows a calculated HOSPITALIZATION rate per 100,000 population by race/ethnicityAs with our case numbers and death rates, this information is discouragingly similar to national reports that indicate significantly worse outcomes among black and brown Americans.  Note that the Hospitalization Rate comparison here surely undercounts Latinx Americans, as there is a large group of “Multirace / Others” with a hospitalization rate much higher than every other group (130.8/100K).

Perhaps the best measure is to compare each group to the County’s overall hospitalization rate of 62.7/100KAs of today:

  • Asian Americans are 14% of Solano’s population, and account for 9% of cases and 11% of hospitalizations, but 16% of deaths.  The hospitalization rate for Solano Asian Americans is 42.5 per 100K (up from 40.9 on Friday).
  • Black Americans are 14% of Solano’s population, and account for 11% of cases, but 18% of hospitalizations, and 23% of deaths.  The hospitalization rate for Black Americans is 66.4 per 100K.
  • Latinx Americans are 26% of Solano’s population, but account for 31% of cases, 34% of hospitalizations, and 27% of deaths.  The hospitalization rate for Latinx Americans is 69.1 per 100K.
  • White Americans are 39% of the population in Solano County, but only account for 20% of cases, 21% of hospitalizations and 20% of deaths.  The hospitalization rate for Solano Whites is 28.5 per 100K.
