1. Alameda County Jail (Santa Rita Jail) – Highlights
Santa Rita Jail’s population surpassed 2100 people over the weekend. The population growth rate suggests that it will continue to rise over the next several weeks, despite the continued threat of COVID-19. 

  • ASCO reports zero active COVID-19 cases in the jail. However, minimal testing, lack of testing prior to quarantine release, and absence of population growth control, suggest that the reported active cases figure is unreliable. In total, there have been 264 reported positive cases.
  • HU 3F and 8B are the housing units designated for individuals with a known exposure to the virus. HU 3E seemingly is no longer designated as a yellow quarantine unit as of Oct. 13.
  • 60 tests have been completed over the weekend. 46 tests are pending results. In total, 4582 tests have been completed since the pandemic began.

Santa Rita Jail Administers No COVID-19 Testing Prior To Quarantine Release, Sheriff’s Office Admits Population Control Is Not A Priority – Weekly Highlights – Breaking Down COVID-19 In CA Jails

Source: The Alameda County Sheriff’s Office updates their website daily with COVID-19 case and testing numbers from the jail. Darby Aono, a Berkeley Law student, has been recording the daily reports in a spreadsheet that dates back to early spring.

2. San Francisco County Jails – Highlights
As of Oct. 13, 2020, there has been 1 new positive case, bringing the total to 68 confirmed cases. There is no new data available for those who have been released while active. There are 2 new resolved cases — total resolved cases are 9, and two less active cases — total active cases in custody is 2. 

The incarcerated population is 822 individuals, 28 more than the last report. The population has consistently remained under 850, which suggests that the SF Sheriff’s Office has been prioritizing population growth control which can enable social distancing and protect incarcerated people from COVID-19.
