Solano County issued new guidance to residents Tuesday, stating that employees in the county who test positive for COVID-19 may return to work after isolating for 10 days, whether or not they continue to exhibit symptoms of the disease caused by the virus. Typical symptoms may include coughing, fever, or respiratory issues.

“Anyone who tested positive and has isolated for 10 days from the date that their symptoms began is no longer infectious, even if some may have lingering symptoms,” said Dr. Bela Matyas, Solano County Health Officer. “We understand that businesses have concerns about employees returning to the workplace; however, re-testing is unnecessary to prove that employees can no longer spread the disease. Once the 10-day isolation has been completed, employees may return to work.”

Matyas added that there is no need for that person to re-test at the end of the 10-day isolation, as “most people with confirmed COVID-19 will continue to have positive test results for several weeks.”

Solano County’s guidance is not completely in line with assessments of the virus by the Centers for Disease Control. A survey of available data found that people with “mild to moderate” COVID-19 symptoms are infectious for no longer than 10 days. However, those with more serious “severe to critical” symptoms have been found to be contagious up to “20 days after symptom onset.”

Additionally, the CDC recommends that a person who tests positive for the disease and exhibits symptoms may end isolation after 10 days if their fever has returned to normal for at least 24 hours and other symptoms have improved.

“These findings strengthen the justification for relying on a symptom based, rather than test-based strategy for ending isolation of these patients, so that persons who are by current evidence no longer infectious are not kept unnecessarily isolated and excluded from work or other responsibilities,” the CDC added.

Solano County COVID-19 positive test rate higher today than State of California

Wednesday, August 5: 78 new cases in 1 day, no new deaths.  Since the outbreak started: 3,884 cases, 38 deaths.

Compare previous report, Tuesday August 4:Summary

  • Solano County reported 78 new cases overnight, total of 3,884 cases since the outbreak started.  Over the last 2 weeks, Solano reported 902 new cases, an average of 64 per day.
  • Deaths – no new deaths today, total of 38 deaths.
  • Active cases – Solano reported 5 more ACTIVE cases today, total of 171.  Note that only 42 of these 171 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”.)
  • Hospitalizations1 fewer currently hospitalized persons today, total of 42.  No more in the total number hospitalized since the outbreak started, 164.  (The County no longer reports Total Hospitalized, but I have added the hospitalization numbers in the Age Group chart.)  Again this week, the County offers no information about availability of ICU beds and ventilators.
  • Testing only 164 residents were tested  today, total of 53,815.  We still have a long way to go: only 12% 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 up from 5.3% on Monday to 6.2% today.
  (The chart may be misleading – see NOTE at top of this page.)  The County posted a high of 9.3% 2 weeks ago on July 22.  CONTEXT: California’s 7-day positivity rate has been falling, and is reported at 5.5% today, lower than Solano County’s 6.2% 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 – 7 new cases today, total of 385 cases. No new hospitalizations, only 2 hospitalizations since the outbreak beganI continue to raise an alarm for Solano’s youth.  It is clear that youth can catch the disease, and it seems too many youth are ignoring social distancing orders!  Cases among Solano youth have increased to 10% of the 3,884 total confirmed cases.
  • Persons 18-49 years of age – 49 new cases today, total of 2,383 cases.  This age group is 41% of the County population, but represents over 61% of the 3,884 total cases, 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.  This young to middle age group is no doubt active, many are providing essential services out among us, and potentially spreading the virus!
  • Persons 50-64 years of age – 17 new cases today, total of 736 cases.  This age group represents just under 19% of the 3,884 total cases.  The County reported no new hospitalizations in this age group today, total of 51 hospitalized since the outbreak began, no new deaths among this age group, total of 4 deaths.
  • Persons 65 years or older – 5 new cases today, total of 379 cases.  This age group represents nearly 10% of the 3,884 total cases. No new hospitalizatons today, total of 66 hospitalized since the outbreak began.  No deaths in this age group today, total of 31.  In this older age group, over 17% of cases required hospitalization at one time, a substantially higher percentage than in the lower age groups.  This group accounts for 31 of the 38 deaths, or 82%.

City Data

  • Benicia added 3 new cases today, total of 90 cases.
  • Dixon added 6 new cases today, total of 205 cases.
  • Fairfield added 27 new cases today, total of 1,266.
  • Rio Vista remained steady today, total of 28 cases.
  • Suisun City added 6 new cases today, total of 297 cases.
  • Vacaville added 16 new cases today, total of 661 cases.
  • Vallejo added 20 new cases today, total of 1,325 cases.
  • Unincorporated areas – Unincorporated areas remained steady today, total of 12 cases.

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 21% of cases, 25% of hospitalizations and 26% of deaths.
  • Black Americans are 14% of Solano’s population, and account for 13% of cases, but 22% of hospitalizations, and 29% of deaths.
  • Latinx Americans are 26% of Solano’s population, but account for 28% 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.

Bay Area Counties recommend 10 to 20 day isolation for COVID-19 patients

Here’s how long most Bay Area counties are recommending COVID-19 patients isolate before returning to work

Those who were hospitalized, or those with underlying conditions, should isolate for 20 days.
ABC7 News, by J.R. Stone, August 4, 2020

SOLANO COUNTY, Calif. (KGO) — Most Bay Area counties are now recommending a 10-day isolation for COVID-19 patients instead of a 14-day quarantine before they come back to work.

The CDC is recommending this and it is also being backed by doctors from UCSF and Stanford.

“For the healthy individual, 10 days will be plenty and we just haven’t seen the evidence for spread after that period of time,” says Dr. Yvonne Maldonado with Stanford Health Care.

New CDC guidelines say those with coronavirus who have mild to moderate symptoms should isolate for 10 days from the start of symptoms or a positive test.

Those who were hospitalized, or those with underlying conditions, should isolate for 20 days.

“But it’s not everyone and there are still other pieces that have to be met, but the 10-day rule is still going to work a lot better for some of our workers,” says Dr. Ralph Gonzales of UCSF.

ABC7 News talked with a business owner in Benicia, who said, “10, 14, or 20 days. It’s hard to make sense of anything right now.”

“I had nothing given to me as a business owner, I don’t know, we’re doing the best we can and the rules change week by week,” says Dennis Cullen who owns Cullen’s Tannery Pub.

In fact, multiple counties are recommending people don’t get a second test before going back to work because dead COVID-19 virus cells can sometimes linger two to three months in patients, even if they’ve recovered.

“Some people do shed virus in our study up to two months, but whether or not that is infectious virus or not, that is unclear,” according to Dr. Maldonado.

Doctors tell us the number of people who are still contagious after that ten or 20-day period is so small, they don’t find it to be a major threat going forward.
