Layers of Safety Health Precautions

Overview

As we discuss mitigation measures, it is important for our community to know how COVID-19 is spread and controlled. COVID-19 is mostly spread by respiratory droplets released into the air when people talk, sing, laugh, cough, or sneeze.  Over the course of the pandemic various mitigation measures have been adopted to prevent the transmission of COVID-19. The Swiss Cheese Respiratory Pandemic Defense recognizes that no single intervention is perfect at preventing the spread of the coronavirus.  

Vaccination is the most effective strategy we have, however each strategy (face masks, distancing, testing, etc.) decreases the risk of in-school transmission.  While  no one layer is 100% effective, a combination of layers is proven effective and has been shown to decrease transmissions.   

1. COVID-19 Vaccine

CDPH strongly recommends that all persons eligible for the COVID-19 vaccine receive them at the first opportunity. COVID-19 vaccines authorized by the FDA have been shown to be safe and effective. Current vaccines are approved for individuals 12 years and older. Vaccines help our immune system fight infections in the future. COVID-19 vaccines protect us from the virus that causes COVID-19 without having to get the illness..

SCUSD, operates Immunization Clinics through the Vaccine for Children (VFC) program and is able to provide COVID-19 vaccine.  SCUSD is committed to working closely with SCPH to provide access to COVID-19 vaccine to all educators, education support staff and students.  SCUSD continues to host a series of vaccination clinics with health partners to do our part in stopping the spread of COVID in our community.

For more information about how to register for a clinic, visit www.scusd.edu/vaccinations.

SCUSD continues to promote the vaccine. View the media toolkit.

2. Face Masks

Universal Use of Face Masks 

Wearing a face mask prevents a person from spreading respiratory droplets while talking, singing, breathing, or coughing. They are meant to protect both the wearer and other people.  Face masks are one of the best tools we have to slow the spread of COVID-19.  Universal masking permits modified quarantine for students, supporting more instructional time and minimizing missed school days for students.

Face Masks Protect our Community from the Spread of COVID-19

  • All SCUSD staff, students in all grades, parents/guardians, community partners and visitors – including fully vaccinated individuals -  are required to wear a face mask at all times in all settings indoors and outdoors, including on the bus, unless they meet a CDPH approved exemption.
  • Individuals may wear a face mask of their choosing that meets CDPH requirements
  • SCUSD will provide face masks at no cost to all individuals who need them. See the CDC Guide to Masks for further information.
  • Face masks are required for outdoor activities.  Face mask breaks may be taken, as long as individuals are spaced more than 6 feet of physical distancing 
    • Individuals should take a break from exercise if any difficulty in breathing is noted and should change their mask or face covering if it becomes wet and sticks to the player’s face and obstructs breathing. Masks that restrict airflow under heavy exertion (such as N-95 masks) are not advised for exercise.

Face Mask Breaks

Some students may need limited face mask breaks throughout the day.  Signs students may display include fidgeting with the front of the face mask or removing it. 

Face Shields

  • Face shields with a cloth drape can be used for those who are unable to wear face masks for medical, pedagogical or developmental reasons, and should be worn using guidance from CDE and Cal/OSHA.
  • Staff must return to wearing a mask when a face shield is no longer needed.

Face Mask Guidance

Guidance for Daily Use of Face Masks
  • Use a freshly washed or clean face masks for each onsite visit
  • Clean your hands with soap and water or hand sanitizer before touching the face mask
  • If you are not already wearing it, apply your face mask before coming onto the worksite 
  • Avoid touching the face mask
  • Avoid eating or drinking while wearing the face mask
  • Face masks should not have valves, as these permit droplet release from the covering, putting others nearby at risk. SCUSD will not permit face masks with valves
  • Replace face mask if soiled or wet
How to Remove a Face Mask
  • Avoid touching the front of the face mask, which is contaminated
  • Only handle the face mask by the ties, bands or loops
  • Throw any disposable face mask in a waste container
  • Wash your cloth face mask by hand with warm water and soap or in the washing machines
  • Wash your hands with soap and water or use hand sanitizer after touching a used face mask
A face mask should not be worn in the following situations:
  • Children under age 2
  • During nap time or sleep
  • Persons exempt from wearing a face mask due to a developmental or medical condition must be confirmed by the school district health team, therapist or medical provider.  
    • A “COVID-19 Student Face Mask Exemption Request and Medical Certification” must be submitted and approved by SCUSD Health Services. See Appendix J.
  • In the event a face mask exemption is approved, the school will notify others who share those spaces and physical distancing will be enforced.  
CDPH guidance allows for times when a face mask can be temporarily removed:
  • When people are eating or drinking.  Individuals must eat and drink in designated spaces and maintain as much physical distance as possible from other persons who are not members of the same household.  The space must be well-ventilated - eating outdoors is best if weather permits.
  • For individuals who are deaf or hard of hearing, when the ability to see the mouth is essential for communication.  Face shields with a cloth drape are recommended in this situation
  • When a person is not sharing a common area, room or enclosed space with others
  • When a face mask is temporarily removed, it should be placed in a clean paper bag or ventilated location (marked with the student’s name and date) until it needs to be put on again.   Replace the mask as soon as you can after these activities to reduce risk of infection.

What if a person refuses to wear a face mask? 

Continual efforts will be made using positive reinforcement teaching strategies to ensure face masks are worn properly. If a concern about wearing masks arises, notify the assigned School Nurse and/or Health Services or assigned supervisor immediately for additional support. Each unique situation will be assessed and support strategies will be employed for the well-being and safety of all. In the event that a student who is not exempt from wearing a face mask continually refuses to wear one, the CDPH requires schools to provide independent study for these individuals.

3. COVID-19 Testing

Used in combination with other mitigation strategies, COVID-19 testing is a valuable tool to support safer in-person instruction. Testing may allow for early identification of cases and reduced transmission. Testing is provided for free on a voluntary basis to all staff, students, their families and other community partners or volunteers.  Parent/guardian notification and consent for minors is obtained via registration on the testing software platform. 

Definitions

Diagnostic testing: Testing used for individuals with symptoms or exposure to COVID- 19 to diagnose COVID-19.  If an individual is symptomatic a rapid antigen test result should be confirmed with a laboratory-based PCR test.

Post-exposure testing: Testing of people who are asymptomatic, but have been exposed to a confirmed or suspected case of COVID-19.  If a person is asymptomatic during quarantine, per CDPH testing guidance, any FDA-approved rapid antigen diagnostic test and/or PCR diagnostic test may be used to exit quarantine.  

Screening testing: Recurrent testing of asymptomatic individuals to detect COVID-19 early and stop transmission quickly.  The goal of screening testing is to detect cases early, and reduce the number of new infections.

Pre-Entry testing: Testing performed prior to entering an event, competition, congregate setting or other venue in order to reduce the risk of spreading infection.  

Do not test:  Individuals who have tested positive for COVID-19 within the last 90 days should not test again until the 90 days have passed, unless experiencing new symptoms.

Where to Get Tested

Testing will be available daily during school hours at each school site upon request during school hours and at the Serna Center District Office.  For more information about current testing availability, please visit www.scusd.edu/covid-19-testing.

Download COVID-19 Testing Registration Flyer

Screening testing will be offered on a weekly basis, but is subject to change based on the case rate in our area.  Anyone experiencing symptoms through the school day or had a known exposure to COVID-19 will be offered onsite testing before going home. 

Two types of COVID-19 tests are available:  

 Self-administered PCR test 

  • Swab sample collected from the nostrils – self administered
  • Molecular test processed in a laboratory
  • Results in 24-48 hours 
  • PCR is the most sensitive COVID test and is  considered diagnostic for COVID-19

 Self-administered BinaxNOW rapid antigen test 

  • Swab sample collected from the nostril – self administered
  • Not processed in a laboratory
  • Results are provided after 15 minutes
  • Detects high viral load, not as sensitive as the PCR test
  • May be used for routine screening, anyone experiencing symptoms, or exposed to COVID-19

4. Screen for Symptoms and Stay Home When Sick

Staff and students must self-screen for symptoms at home daily. If a person is sick or exhibits any symptoms of COVID-19, they may not come to school and will follow Illness and Symptoms Guidelines for Staff and Students (Appendix B).  

Symptoms of illness include fever (100.4 or higher) or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea per CDC guidelines

Stay home until the following CDPH criteria to return to school are met:

 10 days have passed and at least 24 hours fever free and other symptoms improved

OR

Present a negative COVID-19 PCR test and at least 24 hours fever free

OR

Present a note from a healthcare provider that confirms that current symptoms are from a chronic condition or other disease process.

Chronic Conditions

Individuals with non-infectious chronic conditions should not be excluded from attending school or work. If a student or staff member has documented chronic allergic or asthmatic symptoms (e.g., cough or runny nose), a doctor may diagnose an illness other than COVID-19 and provide a note for return to school earlier than 10 days. If there are significant and obvious respiratory symptoms the person must stay home until symptoms improve.  If there are questions about individual cases, contact your school nurse or Health Services.

Allergies

Allergy symptoms are the same as early COVID-19 symptoms.  Many people who test positive for Covid remark, “I just thought it was my allergies.”  If a person has allergy symptoms they should test to rule out COVID-19.  If the test is negative and symptoms improve they can come to work or school. If allergies are chronic and documented by a physician the person should test twice weekly while symptomatic. See Appendix B.

Identifying Sick or Exposed Persons on Site

Any student or staff with symptoms of COVID-19 or who are required to quarantine per CDC guidelines may not enter the school site and will be advised to return home. 

Any student or staff who has close contact with someone outside of school with confirmed COVID-19 may not enter the school site and will be advised to return home.  An exception may be made if persons are coming to site only to receive COVID-19 testing and promptly leave.

SCUSD will be implementing a daily reminder system for home screening through an online screening application for families, students and staff.  For those who do not have access to the application, a list of screening questions will be provided for daily review at home and upon entry to the school or work site.

Students and staff must enter through entry and exit locations at each site.  

  • Provide clear signage visible at all entries with the symptom checklist and reminders for face masking.  Temperature screeners may be available. 
  • Students and staff approaching the entry should be wearing a face mask when in crowds. Face masks will be available for those who do not have their own
  • Any individual experiencing symptoms of illness must be directed to the care room, offered COVID-19 testing with consent, and sent home.
  • Any individual exhibiting one or more symptoms throughout the day will be offered COVID-19 testing and required to wait in the identified care area until they can be taken home or to a healthcare facility, as soon as possible.

5. Hand Hygiene

All students and staff must wash hands frequently. Soap products marketed as “antimicrobial” are not necessary or recommended. If soap and water are not available, use district-approved greater than 60% ethyl alcohol-based hand sanitizer. Training on effective hand washing and use of sanitizer must be provided to all students and staff. Children under age 9 should only use hand sanitizer under adult supervision. Call Poison Control if consumed: 1-800-222-1222.

The following guidelines are recommended for school settings. At minimum, students and staff must wash their hands or use hand sanitizer.

  • Upon arrival to the school site 
  • Before lunch
  • Before leaving the site
  • Upon entry to any new classroom
  • When using the restroom
  • When visibly dirty
  • After using a tissue, coughing into hands
  • Upon arriving home

6. Respiratory Hygiene

Use respiratory hygiene at all times on site. Once a tissue is used, throw it away in a waste container and then wash hands with soap and water or use hand sanitizer. Do not touch the face.  Reinforce  respiratory hygiene or cough/sneeze etiquette, including use of tissues and elbows by using signage, training, and lessons.  See Appendix H for signage.

7. Contact Tracing & Reporting COVID-19 Cases

Expecting and planning for the occurrence of one or more cases of COVID-19 helps the district respond immediately to mitigate the impact, minimize spread of COVID within the school/work site, and allow the school/work site to remain open.  

To help prevent the spread of COVID-19 in the community,  Sac City Unified Health Services will be conducting COVID-19 contact tracing within the district. Appendix I: Procedures for Managing and Preventing the Spread of COVID-19 in the SCUSD Community provides directions for when a person within the district becomes ill with COVID-19 or is exposed to COVID-19 and was developed based on CDPH and SCPH guidelines.

  • Any individual who tests positive for COVID-19 must immediately notify their school-site administrator or supervisor.  
  • Administrators/supervisors must immediately email the District COVID Response Team

Click here for detailed guidelines about cases and exposures in Appendix I: Procedures for Managing and Preventing the Spread of COVID-19 in the SCUSD Community.

8. Adequate Ventilation

SCUSD is ensuring there is sufficient ventilation in all school classrooms and shared workspaces per the Centers for Disease Control (CDC) and the American Society of Heating, Refrigerating, and Air- Conditioning Engineers (ASHRAE).

  • HVAC filters will be replaced three times per year rather than once per year as is currently the practice.  MERV-13 filters have been installed wherever possible.
  • Each HVAC system within the District has been cleaned, tested, and tuned up as needed to ensure the highest operating efficiency possible. 
  • HVAC units are programmed to turn-on and run continuously for a minimum of 2 hours before and for a minimum of 2 hours after classrooms are occupied.
  • HVAC systems are reprogrammed to run continuously when windows and doors are open.
  • In order to maximize outside airflow, windows and doors will be opened so long as it is deemed safe to do so.
  • Portable HEPA filtration units have been provided in classrooms where MERV-13 filtration is not available.
  • Specific practices to avoid:
    • Classrooms or buses with no ventilation or additional airflow
    • Classrooms or buses with increased airflow across occupants (e.g., oscillating or box fans blowing into the classroom

9. Poor Air Quality

Schools must balance the COVID-19 prevention benefits of ventilation and outdoor activity with the outdoor air quality.  On projected poor air quality days schools will monitor Air Now and Spare the Air websites for air quality readings. When the Air Quality Index (AQI) is poor schools are advised to close windows and doors.

When you can visibly see or smell smoke or AQI is 151 or over:

  • Close all windows and doors
  • Adjust HVAC systems to prevent outdoor air from being pulled into the building when possible
  • Eat in the multiple purpose room, other available spaces, or the classroom
  • Move outdoor activities indoors
  • Follow all guidance issued by CDPH or SCPH about air quality and COVID mitigation

10. Cold Weather

Schools must balance the COVID-19 prevention benefits of ventilation with cold weather.  Individuals are advised to dress warmly as cold weather approaches.  On cold days doors and windows should remain cracked if possible to ensure increased ventilation. Portable HEPA filtration units provided to spaces where MERV-13 filtration is not available MUST be plugged-in and utilized correctly.

11. Disinfecting Procedures

Disinfecting Materials

Due to the unprecedented nature of the COVID-19, and the awareness surrounding it, the Sacramento City Unified School District understands the desire to protect students and staff  from possible infection.

Disinfecting Procedure

Regularly disinfect high-touch areas daily.  Frequently touched surfaces in the school include, but are not limited to:

  • Door handles
  • Light switches
  • Sink handles
  • Bathroom surfaces
  • Tables
  • Student Desks
  • Chairs 

If an individual who is positive for COVID has been physically present, the spaces where the individual spent a large proportion of their time (e.g., classroom office) should be disinfected. Frequent disinfection can pose a health risk to children and students due to the strong chemicals often used and so is not recommended in the school setting unless a positive case of COVID has been identified. 

Consistent with recommendations by the U.S. Environmental Protection Agency (EPA), the district strives to select disinfectant products with ingredients that reduce the impact on those with asthma.

Inventory Controls

  • Order supplies for start and plan for inventory management
    • Face masks for students and staff, individuals may use their own face covering that meets all current requirements
    • Disposable face masks for care room
    • Face shields or goggles for sick room and for teachers
    • Hand sanitizer – in every room, used by every individual entering
    • Spray bottles and disinfectant and paper towels- every room to clean surfaces 
    • Gloves – for use in case of vomiting or helping sick or injured student
    • Thermometers – thermometer needed at each site for sick room
    • Handwashing stations if insufficient sink access at sites
  • Backstock of Personal Protective Equipment (PPE)
  • Proper ordering procedures from central location/system
  • Use of district-approved products only

Some items an individual may normally use at home are not allowed for use in schools due to State and Federal policies in place for student health and safety, unless properly trained by the California Department of Pesticide Regulations.  Aerosol spray containers are not allowed on school property for safety reasons.  While the district is making every effort to ensure that supplies are replenished at our school sites, the following is a list of items the District can recommend for individual procurement and use:

Hand Sanitizer – It is recommended that hand sanitizer be at least 60% ethyl alcohol based in order to kill the virus and any other bacteria. 

Disinfecting  Wipes – Disinfecting wipes are effective and allowable, but it is important to read and follow all instructions. 

It is critical that individuals read and follow the directions for any cleaning product every time before use.

12. Physical Distancing 

Physical distance has been shown to reduce transmission and although distance criteria per CDPH are no longer required in schools, all individuals should maintain as much physical distance as practicably possible.  Physical distancing should be practiced as much as possible when individuals are exempted from face masks or in situations where masks are removed, such as mealtimes. Where cafeterias or group dining spaces must be used, physical distancing will be maximized.  Maintaining seating charts at lunch periods in elementary schools is critical for contact tracing in positive cases of COVID.
