Important Definitions

Isolation is the term used when individuals test positive for COVID

Quarantine is the term used for those who were exposed to COVID

Exposure is defined as within 6 feet, for 15 or more minutes combined during a 24 hour period, masked or unmasked

Fully Vaccinated aka Fully Updated refers to someone who is fully vaccinated AND boostered if eligible

Unvaccinated refers to someone who is:

Not previously fully vaccinated

Previously fully vaccinated but has not received a booster (if eligible), including those who have had a COVID infection in the last 90 days

Eligible for Booster is someone who is 12 years and up and has received:

2 Pfizer doses, 5 or more months ago

2 Moderna doses, 6 or more months ago

2 J & J doses, 2 or more months ago


3 or more COVID-19 cases among individuals in an exposed group within a 7-day period

SYMPTOMS (with or without a known exposure)

If you develop ANY of the following symptoms, keep your child home, inform your child’s teacher and Emily Cortes at [email protected].

•      Cough

•      Fever

•      Shortness of breath

•      Nausea, vomiting, or diarrhea

•      Body aches 

•      Headache

•      Sore throat

•      Runny nose

•      New loss of taste or smell


Asymptomatic (regardless of vaccination status) – No Quarantine Needed – close contacts can continue coming to school/work so long as they remain asymptomatic and do NOT test positive, even if they are living with a positive case. Exposed students, regardless of COVID-19 vaccination status, should get tested for COVID-19 with at least one diagnostic test (e.g., an FDA-authorized antigen diagnostic test, PCR diagnostic
test, or pooled PCR test) obtained within 3-5 days after last exposure, unless they had
COVID-19 within the last 90 days. It is also strongly recommended that an exposed person wear a well-fitting mask indoors around others for at least 10 days following the date of last exposure, if not already doing so. 

If you have a positive case in your household, here are precautions and mitigation measures to reduce risk of household transmission:

·         Separate bedroom – alternatives: head of beds at opposite ends of room, 6ft+ apart 

·         Separate bathroom – alternatives: showering at separate times of day, wiping down high touch surfaces after shower steam settles, keeping toothbrushes separated, etc.

·         Keeping at least 6 feet of distance at all times

·         Wearing masks when sharing common spaces indoors (both the positive individual and the others nearby the positive individual)

·         Increasing ventilation in the home.

All persons with COVID-19 symptoms, regardless of vaccination status or previous infection, should:

  • Self-isolate and test as soon as possible to determine infection status. Knowing one is infected early during self-isolation enables (a) earlier access to treatment options, if indicated (especially for those that may be at risk for severe illness), and (b) notification of exposed persons (close contacts) who may also benefit by knowing if they are infected.
    • For symptomatic persons who have tested positive within the previous 90 days, using an antigen test is preferred.
  • Remain in isolation while waiting for testing results. If not tested, they should continue isolating for 10 days after the day of symptom onset, and if they cannot isolate, should wear a well-fitting mask for 10 days.
  • Consider continuing self-isolation and retesting in 1-2 days if testing negative with an antigen test, particularly if tested during the first 1-2 days of symptoms.
  • Continue to self-isolate if test result is positive, follow recommended actions below (Table 1), and contact their healthcare provider about available treatments if symptoms are severe or they are at high risk for serious disease or if they have any questions concerning their care.


Individuals infected with COVID-19 may leave isolation after day 5 if their symptoms are not present or are mild and improving, provided they have not had a fever within the past 24 hours and are not taking fever-reducing medications.

  • If a fever is still present after day 5, isolation should continue until 24 hours after the fever resolves.
  • Individuals are no longer required to provide a negative test result to resume school/work following their 5 day isolation.
  • SICS will notify families of positive cases in the event of an outbreak (as defined above).

If a student receives a positive COVID-19 test, whether PCR or antigen, symptomatic or not email [email protected] with the following information:

Name of your child * grade level of child * date of positive test * date of symptoms ( if any) * Dates of attendance at school prior to the first symptoms (within 2 days) or dates of attendance prior to positive test if asymptomatic (within 7 days)
