Comparing June and July COVID numbers in Solano County cities – dramatic increases

[NOTES: For June-July comparison, see City Data below.  Solano County publishes a DAILY update, and displays past weeks and months in epidemic curve charts.  However, the curve charts do not display an accurate number of cases for the most recent days, as there is a lag time in receiving test results.  This methodology is accurate in a way, but it misleads the public by consistently displaying a recent downward curve which is often corrected upward on a later date. For a complete archive of day by day data, see my Excel ARCHIVE – R.S.]

Friday, July 31: 91 new cases today, no new deaths.  Since the outbreak started: 3,611 cases, 37 deaths.

Compare previous report, Thursday July 30:Summary

  • Solano County reported 91 new cases today, total of 3,611 cases since the outbreak started.  Over the last 7 days, Solano reported 482 new cases, an average of 69 per day.
  • Deaths – no new deaths today, total of 37 deaths.
  • Active cases – Solano reported 10 fewer ACTIVE cases today, total of 240.  On July 16, Solano hit a record high of 440 active cases.  Note that only 40 of these 240 people are hospitalized, so there are a lot of infected folks out among us, hopefully quarantined.  One wonders… is the County equipped to contact trace so many infected persons?  (See SF Chronicle report on contact tracing in Bay Area – “Solano County did not respond”.)
  • Hospitalizations10 fewer currently hospitalized persons today, total of 40.  1 more in the total number hospitalized since the outbreak started, 163.  (The County no longer reports Total Hospitalized, but I have added the hospitalization numbers in the Age Group chart.)  For the 5th day in a row, the County offers no information about ICU beds and ventilators.  Apparently, the County does not collect or receive this data from our hospitals, but relies on data collected by the State.  You would think that when the County gathers data on Currently Hospitalized they could also easily collect the ICU bed and ventilator data.  Or… ??
  • Testing Exactly 500 (?!) residents were tested since yesterday, total of 52,557.  But we still have a long way to go: only 11.7% of Solano County’s 447,643 residents (2019) have been tested.

Percent Positive Test Rate

Solano County reported today’s 7-day percent positive test rate is down from 6.5% yesterday to 5.8% today.  (The chart may be misleading – see NOTE at top of this page.)  The County posted a high of 9.3% on July 22.  CONTEXT: California’s 7-day positivity rate is reported today at 7.0%.  Increasingly, health officials and news reports are focusing on percent positive test rates.  This information is immediately important, as test positivity is one of the best metrics for measuring the spread of the virus.  Positive test rates in California and other southwestern states have been on the rise.

By Age Group

  • Youth 17 and under – only 1 new case today, total of 354 cases. No new hospitalizations, only 2 hospitalizations since the outbreak began.  2 weeks ago, there were 243 cases among this age group – we’ve seen 111 new cases in just 14 days.  Despite the recent correction, I continue to raise an alarm for Solano’s youth.  Cases among Solano youth have increased to nearly 10% of the 3,611 total confirmed cases.
  • Persons 18-49 years of age – 68 new cases today, total of 2,219 cases.  This age group represents over 61% of the 3,611 total cases, 3/4 of today’s new cases and by far the highest percentage of all age groups.  Good news is that the County reported no new hospitalizations in this age group today, total of 45 hospitalized since the outbreak began, and no new deaths among this age group, total of 3 deaths.  However, this young and active age group may be out among us, spreading the virus!
  • Persons 50-64 years of age – 11 new cases today, total of 683 cases.  This age group represents just under 19% of the 3,611 total cases.  The County reported no new hospitalizations in this age group today, total of 51 hospitalized since the outbreak began, and no new deaths among this age group, total of 4 deaths.
  • Persons 65 years or older – 11 new cases today, total of 354 cases.  This age group represents nearly 10% of the 3,611 total cases. 1 new hospitalization, total of 65 hospitalized since the outbreak began.  No new deaths, total of 30.  In this older age group, over 18% of cases required hospitalization at one time, a substantially higher percentage than in the lower age groups.  This group accounts for 30 of the 37 deaths, or 81%.

Race / Ethnicity

The County report on race / ethnicity includes case numbers, hospitalizations, deaths and Solano population statistics.  There are also tabs showing a calculated rate per 100,000 by race/ethnicity for each of these boxes.  This information is discouragingly similar to national reports that indicate worse outcomes among black and brown Americans.  As of today:

  • White Americans are 39% of the population in Solano County, but only account for 20% of cases, 25% of hospitalizations and 27% of deaths.
  • Black Americans are 14% of Solano’s population, and account for 13% of cases, but 23% of hospitalizations, and 30% of deaths.
  • Latinx Americans are 26% of Solano’s population, but account for 30% of cases, 32% of hospitalizations, and 24% of deaths.
  • Asian Americans are 14% of Solano’s population, and account for 9% of cases and 12% of hospitalizations, but 15% of deaths.
