What We Know

Protecting our Students and Staff

  •  Avoiding Transmission

    COVID-19 is primarily transmitted through droplet transmission. Transmission happens when respiratory droplets from speaking, yelling, coughing, or singing come in contact with mucous membranes (eyes, nose, mouth). This means that to protect ourselves, we need to:


    1. Reduce droplet transmission by:

         a. requiring masks for all students and staff

         b. physical distancing from each other


    2. Continue to wash hands frequently and to keep surfaces clean by using soap and disinfectants


    3. Ensure we are limiting the presence of COVID-19 on our campuses by:

         a. opening campuses during periods of lower community transmission, as defined by ACPHD

         b. symptom screening on a daily basis for all students and staff

         c. providing regular COVID-19 surveillance testing  


    What We Know About COVID-19, Children, and Reducing Risk

    As our knowledge of COVID-19 has grown over time, we now know that:

    • Personal protective equipment (PPE), social distancing, and regular hand washing/sanitizing are the most important ways we can prevent transmission in adults and children.
    • Preventing person-to-person transmission, via respiratory droplets, is more important than frequent cleaning and disinfection. COVID-19 mainly spreads from person-to-person via respiratory droplets.
    • Exposure risk is a gradient, rather than an all-or-nothing condition. A rule of thumb is that a person must spend at least 15 minutes within six feet of someone with COVID-19 to be at risk of infection.
    • Universal face coverings decrease risk. Being outside is lower risk than being inside. Other risk factors include whether the infected person was sneezing or coughing, or doing an activity that produced more respiratory droplets (not talking < quiet conversation < loud talking < singing).
