Here is today’s COVID-19 update from the County Health and Human Services Agency with data through March 8, 2021.

Vaccination Progress:

  • More than 1.15 million COVID-19 vaccine doses have been delivered to the region, and over 1.1 million have been logged as administered. Of those vaccinated to date, more than 355,000 people, or 13.2% of San Diegans 16 and older, are fully immunized.
  • Overall, more than 651,000 County residents have received at least one shot of the two-dose vaccine. That’s 24.2% of those eligible.
  • Those receiving the one-dose Johnson & Johnson vaccine are being added to the total of fully vaccinated San Diegans.
  • The difference between doses delivered and those used in a vaccination represents approximately what is expected to be administered in the next seven days and doses still to be entered in the record system.
  • More information about vaccine distribution can be found on the County’s vaccination dashboard. For details on groups currently eligible and vaccination opportunities, visit

State Metrics:

  • San Diego County’s state-calculated, adjusted case rate is currently 8.8 cases per 100,000 residents (as of March 9) and the region is in Purple Tier or Tier 1.
  • The testing positivity percentage is 3.3%, placing the County in Tier 3 or the Orange Tier. While the testing positivity rate for the County qualifies it for Tier 3, the state uses the most restrictive metric – in this case the adjusted case rate – and assigns counties to that tier. Therefore, the County remains in the Purple Tier or Tier 1.
  • The County’s health equity metric, which looks at the testing positivity for areas with the lowest healthy conditions, is 4.5% and is in the Orange Tier or Tier 3. This metric does not move counties to more restrictive tiers but is required to advance to a less restrictive tier.
  • The California Department of Public Health assesses counties on a weekly basis. The next report is scheduled for Tuesday, March. 16.

Community Setting Outbreaks:

  • No new community outbreaks were confirmed March 8.
  • In the past seven days (March 2 through March 8), 24 community outbreaks were confirmed.
  • The number of community outbreaks remains above the trigger of seven or more in seven days.
  • A community setting outbreak is defined as three or more COVID-19 cases in a setting and in people of different households over the past 14 days.


  • 11,766 tests were reported to the County on March 8, and the percentage of new positive cases was 4%.
  • The 14-day rolling average percentage of positive cases is 3.2%. Target is less than 8.0%.
  • The 7-day, daily average of tests is 13,187.
