Case Rates by ZIP Code

Two types of case rate are available for each ZIP Code:

  • The County of San Diego publishes  7-dayaverage case rates that reports the average number of new cases each day during the first seven days of the last 14 days, per 100,000 people. The site also includes a map aligned to the tier system used by the Blueprint for a Safer Economy, that illustrates transmission rates within each of the county’s ZIP codes and jurisdictions .
  • An unofficial 14-day case rate is also available. This case rate gives the number of cases that were reported over the previous 14-day period, per 100,000 people. This metric is not used by the county or state, but is included as a key indicator by the Centers for Disease Control and Prevention (CDC) in their  Indicators for Dynamic School Decision-Making. Click here for a brief video overview of the CDC indicators and on the 14-day case rate. This rate is updated each Tuesday using data from the previous 14-day period.

School leaders are encouraged to consult with public health experts for interpreting these metrics and to determine how each should be applied in decision making.
