COVID-19 Decision Trees
Changes to the definition of 'close contact' and its application in Cal/OSHA's Emergency Temporary Standards are reflected in the latest COVID-19 decision tree, updated June 28, 2022. The Spanish version is also current. If you are not seeing the most current version of the decision tree, please clear your internet cache, reload the page, and download the correct version. The decision tree will be updated as needed to reflect the latest public health guidance. Please check this page weekly to ensure you are using the latest version.
The e-Decision Tree (last updated April 11) is a digital representation of the San Diego County COVID-19 K-12 Decision Trees developed by the San Diego Supercomputer Center, UC San Diego in collaboration with the UC San Diego School of Medicine Division of Child and Community Health, and the San Diego County Office of Education. The e-Decision Tree has been updated to include the new “group tracing” option and is now able to calculate dates for testing and return for household exposures.
