Update Letter #2 About Coronavirus
Posted 3/4/20

March 4, 2020


Dear Simi Valley Schools Community:


As we advised last week, we will continue to regularly update our community with information about the coronavirus/2019-nCoV and its impact on our schools. We continue to monitor the situation through our county and state public health and education offices, and we are closely watching our neighboring counties for their conditions and responses.


This week, we are continuing our normal classroom and school facility disinfection procedures and we have begun implementing additional measures for cleaning/sanitizing our campuses and offices. We wish to share the following information with you:

  1. As part of the Simi Valley Unified School District's Pandemic Response Protocol, the District prioritizes sanitizing common surfaces such as doorknobs, light switches, drinking fountain handles, desktops, sinks, bathrooms, thermostats, school bus seats and rails and more. These areas are cleaned with disinfectant cleaners every day. Restrooms are sanitized twice each day.
  2. In addition, the District is starting to use a product called Protexus Evaclean System (PES) in our middle and high schools and in our school buses. (Additional systems are on order for our elementary schools.) PES takes advantage of the negative ion charge found on room surfaces and puts a positive ion charge on antiseptic droplets. These droplets are then attracted to all room surfaces and in hard-to-reach places like a magnet. PES is not a spray or fogger. It is an electrostatic system where the antiseptic coating covers surfaces and objects 360 degrees, which provides three times the coverage over conventional sprayers. PES also increases the sanitization of a room 80% faster, which allows entire schools to be sanitized quickly and effectively. (PES takes only 2-3 minutes for each classroom or office to be sanitized with this system.)
  3. The cleaner used is called sodium dichloro isocyanurate (NaDCC). NaDCC possesses a reserve killing power that continues to work even after contact with organic soil matter, making it a better cleaner than bleach, which is deactivated upon contact with organic soil matter. Overall, NaDCC has four times the killing power of bleach. Disinfecting and sanitizing more areas in this manner is the simplest and most effective way to reduce illnesses. NaDCC produces no caustic results and is approved by the Environmental Protection Agency (EPA) and the World Health Organization (WHO) as a disinfectant for potable water with no observable negative health effects over a lifetime of consumption.

We have received many questions about hand sanitizers. Students are allowed to bring their own hand sanitizers to school for their personal use.


Please remember the following measures to help prevent the spread of COVID-19:

  • Wash your hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer.
  • Avoid touching your eyes, nose and mouth with unwashed hands.
  • Avoid close contact with people who are sick.
  • Keep your children home when they are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces.
  • Individuals with chronic health issues and/or individuals experiencing severe symptoms should be evaluated by a medical professional.
  • Get vaccinated for the flu every year.

We also wish to remind our community that we remain steadfastly committed to observing everyone’s civil rights. District programs, activities, practices and employment shall be free from discrimination, harassment, intimidation and bullying based on race, color, ancestry, national origin, immigration status, ethnic group identification or where anyone may have traveled.


By working together to follow these important guidelines, we can help keep our students, staff and community healthy. There is information on our district website,, which contains links and current information about the coronavirus, and which will also be updated regularly.

Thank you,

Sean Goldman

Assistant Superintendent
