The chart below reflects the new California Department of Public Health (CDPH) isolation and quarantine periods guidance from January 6, 2022, which overrides the Cal/OSHA COVID-19 Prevention Emergency Temporary Standards in certain circumstances.

New Infographic: Upgrade Your Mask
CDPH has produced a new infographic encouraging Californians to upgrade their mask.
To help slow the spread and protect yourself and others, upgrade your mask. Wear an N95, KF94, or KN95 if you can, especially in crowded public settings.


Email and text messages will still be sent from the Principals at impacted sites to students and families directly impacted, and school personnel, directly impacted by the positive case at a site, will receive a Catapult message. Districtwide, every one of us will now have access to the MJUSD COVID-19 Dashboard so any one of us can determine how many positive cases occurred each day.
Questions can be sent to Supervisor of Health and Wellness, Jordan Wells, at or at 740-6487.

What to Consider When Choosing a Mask for Kids
Masks are a great way to reduce COVID-19 in schools. Masks help stop the virus from getting into the air if the person wearing it is infected. Masks also help protect people from breathing in the virus from the air.

CDPH has released tips and resources for choosing the best mask for children. KF94s and KN95s are both available in kid's sizes with good fit and good filtration. N95s also provide excellent fit and filtration but will not fit smaller faces. Kid-sized medical masks provide good filtration, but do not provide a tight fit. Fabric masks can help reduce the spread of COVID-19, but many have both poor fit and filtration.
