Here is today’s COVID-19 update from the County Health and Human Services Agency with data through Nov. 30.

State Metrics:

  • Under the state’s system for determining COVID-19 risk, San Diego County is the Purple Tier, or Tier 1. The state uses the more restrictive measure of case rate or testing positivity to assign tiers regarding what activities are permitted. Indoor operations at restaurants, gyms, places of worship and movie theaters are currently not allowed.
  • The County’s state-calculated, adjusted case rate is currently 15.3 cases per 100,000 residents and the region is in Purple Tier or Tier 1 for that metric.
  • The testing positivity percentage is 2.3%, placing it in Tier 3 or the Orange Tier for that metric.
  • The County’s health equity metric, which looks at the testing positivity for areas with the lowest healthy conditions, is 10.6% and it’s in the Purple Tier or Tier 1. 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 announces tier assignments at least once a week.

Community Setting Outbreaks:

  • Seventeen new community outbreaks were confirmed on Nov. 30: six in retail settings, five in business settings, two in restaurant/bar settings, and one each in a faith-based setting, a TK-12 school setting, a daycare/preschool/childcare setting and a grocery setting.

  • The 7-day, daily average of tests is 18,099.
