Updated CDPH and CCHS Guidance for COVID-19 “Isolation” Reduced to 5 Days with Negative Test
Posted 1/10/22

Message from Superintendent Dr. Adam Clark:


Dear Families, Students and Staff:                          

On Friday, January 7, the California Department of Public Health (CDPH) and Contra Costa Health Services (CCHS) updated guidance specifically for schools related to student and staff isolation for positive COVID cases. We continue to wait for the CDPH to update their K-12 guidance for close-contacts who need to quarantine.

Current CDPH guidance recommends that individuals follow CDPH recommended action regarding isolation, which applies to everyone who has tested positive for COVID-19, regardless of vaccination status, previous infection, or lack of symptoms.

Isolation Guidance for Those Testing Positive

  • Stay home for at least 5 days. Positive test date or symptom onset is "day 0."
  • Isolation can end after day 5 IF symptoms are not present or are resolving AND a diagnostic specimen (rapid test preferred) collected on day 5 or later tests negative.
  • Although PCR tests are acceptable, they are (now) much less practical and useful in attempting to return to school after 5 days.
  • If unable to test or choosing not to test, and symptoms are not present or are resolving, isolation can end after day 10.
  • If fever is present, isolation should be continued until fever resolves.
  • If symptoms other than fever are not resolving, continue to isolate until symptoms are resolving or until after day 10.
  • Wear a well-fitting, high-quality mask around others for a total of 10 days, especially in indoor settings. 

Students who are beyond five days from a positive test or the onset of symptoms and are symptom-free may return to school with proof of a negative test.

  • Take an over the counter rapid test
  • If you have taken a PCR test in the community over the weekend, please note results for PCR tests may take longer than 24 hours. 

If taking an over the counter rapid test or PCR prior to return, students or parents should show evidence of a negative test to the school office upon returning to school. Please do not return to your school prior to receiving a negative test result.

I appreciate everyone’s ongoing assistance in keeping our schools safe. We will continue to make it through this challenging time as we work together.
