Person gets vaccinated

Here is today’s COVID-19 update from the County Health and Human Services Agency with data through March 3, 2021.

Vaccination Progress:

  • Of the 1.1 million COVID-19 vaccine doses delivered to the region, more than 997,000 have been logged as administered. Of those vaccinated to date, more than 303,000, or just over 11 percent of San Diegans 16 and older, are fully immunized.
  • Overall, more than 608,000 County residents have received at least one shot of two-dose vaccine. That’s 22.6 percent of those eligible.
  • 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 10.8 cases per 100,000 residents (as of March 2) and the region is in Purple Tier or Tier 1.
  • The testing positivity percentage is 4.2%, 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 6% and is in the Red Tier or Tier 2. 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. 9.

Community Setting Outbreaks:

  • Six new community outbreaks were confirmed March 3: four in business settings and two in restaurant/bar settings.
  • In the past seven days (Feb. 25 through March 3), 29 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.


  • 17,763 tests were reported to the County on March 3, and the percentage of new positive cases was 3%.
  • The 14-day rolling average percentage of positive cases is 3.6%. Target is less than 8.0%.
  • The 7-day, daily average of tests is 12,947.
