COVID-19 Information



California’s state of emergency related to COVID-19 officially ended on February 28; likewise, Los Angeles County will end its state of emergency on March 31.

On March 13, the Los Angeles County Department of Public Health (LACDPH) revised its requirements for managing COVID-19 to fully align with the state’s.  Those infected with COVID-19 may now exit isolation after the fifth day if there is no fever and symptoms are mild or improving; testing is no longer required but strongly recommended.  Likewise, those who are exposed to someone who has tested positive for COVID-19 are no longer required to wear a mask for ten days, though it is strongly recommended.  For more information, please visit LACDPH’s website.

Beginning April 1, this webpage and its contents will no longer be updated and will eventually be archived.  Should there be a need to provide updates or information about COVID-19, they will be available on the district’s homepage under “News and Announcements.”

MUSD COVID Dashboard

To ensure transparent and accurate information regarding COVID-19 cases within our school district, we are providing a dashboard as of the start of the 22-23 school year (Wednesday, August 17). All data in the dashboard indicate confirmed active cases among our students and staff.
The dashboard data is updated within 24 hours of learning of any confirmed active cases and after any close contacts have been notified.  The dashboard may not be updated on weekends or other non-school days. Cases are removed from the dashboard once the student or staff member is cleared to return to school.

County Guidelines for Close Contacts

Asymptomatic close contacts are not required to quarantine; they may remain on campus if they follow all requirements for close contacts. Specifically:

  1. Monitor symptoms for 10 days.
  2. Wear a highly protective mask around others indoors, except when eating or drinking, for 10 days after the last date of exposure.
  3. Test with an FDA-authorized viral COVID-19 test (e.g., PCR or Antigen test, including at-home tests) within 3-5 days since the last date of exposure.*

*NOTE: Asymptomatic students and staff close contacts who were previously infected with COVID within the last 90 days are exempt from testing but must mask around others indoors for 10 days after the last date of exposure.


Close Contact: The preferred method for determining which persons are considered to have been exposed to a case (close contact) during the infectious period is if they shared the same indoor airspace at school with the infected person for 15 minutes or more over a 24-hour period. In large indoor airspaces: those considered exposed may be limited to 1) those in a pre-defined or identifiable group (e.g., teammates, club members, cohort, etc.) or 2) those within 6 feet of the infected person for 15 minutes or more over a 24-hour period within that large indoor airspace.

Quarantine Flow Chart

MUSD provides at-home COVID-19 test kits for everyone who needs them. These tests may also be used to end your student’s isolation early if they test negative on or after day five.

Please note that the California Department of Public Health recently extended over-the-counter COVID tests beyond their expiration dates. 

Please contact your student's school site if you want a home test.

  • When you develop symptoms
  • When exposed to someone with COVID-19
  • On Day 5 (or after) after exposure
  • On Day 5 (or after) after testing positive
What to do if your home test result is positive?
  • Isolate yourself from others
  • Notify your school with the results

Information About Masks

As of March 12, 2022, the universal masking requirement of K-12 Schools and Childcare has been lifted. Both CDPH and County Public Health strongly recommend that individuals in these settings continue to mask while indoors until transmission rates are much lower.
