By Roger Straw, Monday, June 7, 2021

Solano County reports 20 new infections over the weekend, but there were surely more.  County reports negative 9 cases in Vacaville.

Solano County COVID-19 Dashboard – SUMMARY:

Solano County reported 20 new COVID cases over the weekend, but the actual total was closer to 40 (explanation below).

Actually more like 40 cases over the weekend…
Today’s total of 20 new cases includes a negative number (-9) for Vacaville, indicating an adjustment of some kind.  The 6 other Solano cities had a total of 29 new cases, so that 29 – 9 = today’s supposed total of 20.  Stay with me here – it is certain that Vacaville would have had 4 or more new cases per day (based on previous 4 weeks averages). So it is highly likely that the County actually had around 12 new Vacaville cases over the weekend and an actual total of 29 from the 6 other cities + about 12 from Vacaville = about 41 new cases.  Got it?  The math would then also indicate that the Vacaville adjustment was approximately -21 cases (41 – 21 = 20).

Outbreak at the State Prison in Vacaville
Who were the 21, and why were they counted last Friday and removed today?  Based on an email from Dr. Bela Matyas, my hunch is that they were inmates in the State Prison in Vacaville.  Responding to my question as to the reason for last week’s atypical surge of 108 new cases from Vacaville, Dr. Matyas wrote on June 4 that “There is an outbreak at the state prison, which accounts for most of those cases.”  My BenIndy speculation today is that some of those prisoners were initially counted as Solano cases, but later determined to be more properly documented according to the person’s city of residence.

Oh, and…
Of course, Vacaville MIGHT have had more than an average number of new cases over the weekend.  It’s entirely possible, for instance, that there were 10-15 new cases per day.  That would mean Solano actually saw 30-45 new cases in Vacaville, for a Countywide total of 59-74 new cases over the weekend, and a subtraction of 39 to 54 Vacaville prisoners.  My guess is we’ll never know for sure.  The County gives daily cumulative totals without a lot of detail.

Monthly: Solano County saw 1,288 new cases in April, an average of 43 per day.  In May, Solano reported 920 new cases, an average of 30 per day.  Over the weekend, maybe about 41 new cases, an average of only 14 per day.

Solano County reported no new deaths today.  The County total is now 244 deaths since the pandemic began.

SOLANO NOW IN ORANGE TIER – Solano County was finally moved into the orange tier last week, the last Bay Area County to leave the red tier.  See details on remaining restrictions and new freedoms in the County’s press release, also in the account of the Vallejo Times-Herald.
