COVID-19 Terms & Definitions
Vaccination
Fully Vaccinated
Children ages 5-17 who completed their initial series; adults boosted or vaccinated but not yet booster eligible; or anyone who had COVID-19 within the last 90 days. Fully vaccinated types include the following:
-
Boosted - Completed a primary series of COVID vaccination (One dose of Johnson & Johnson or two doses of Moderna or Pfizer) and received a booster shot of any FDA authorized vaccine at least 14 days before exposure.
-
Vaccinated and ineligible for booster - Completed an initial series of COVID-19 vaccination (One dose of Johnson & Johnson or two doses of Moderna or Pfizer) but not yet eligible for a booster. (J&J dose less than 2 months ago, final Pfizer dose less than 5 months ago, or final Moderna dose less than 5 months ago.)
-
Vaccinated and age 5-17 - Anyone ages 5-17 who completed their initial series of COVID-19 vaccination, even if not yet boosted.
-
Recently COVID positive - Anyone who had COVID-19 within the last 90 days will follow the guidance under “fully vaccinated” for the purpose of the COVID-19 Prevention Plan.
Not Fully Vaccinated
Age 18+ who received initial series & are booster-eligible but have not yet received a booster. Not fully vaccinated types include the following:
-
Vaccinated, booster eligible and unboosted - Completed an initial series of COVID-19 vaccination and is eligible for a booster but has not received a booster at least 14 days before exposure.
-
Unvaccinated - Did not complete an initial series of COVID-19 vaccination. Includes people who never received a single J&J shot, received only one dose of a two-dose series, or who received a non-WHO or FDA authorized vaccination.
COVID Protocols
Day 0 for a Positive Case - Date of the COVID positive result (on an individual test), or onset of symptoms (whichever comes first). Cases are tracked via COVID Dashboard.
Day 0 for a Close Contact - Date of last contact with a person who has been identified as positive for COVID. Note: Day 0 may or may not be the same as the day that a potential exposure is reported. This is the last day of exposure.
Isolation - Isolation is used to separate people with confirmed or suspected COVID-19 from those without COVID-19. You isolate when you are sick or when you have been infected with the virus, even if you don’t have symptoms. It means staying home and away from everyone, even in your own household.
Close Contact - Someone sharing the same indoor airspace, e.g., home, classroom, etc., for a cumulative total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes) during an infected person's infectious period.
Infectious Period - The timeframe an infected person can transmit a pathogen to a susceptible host. The infectious period for COVID-19 starts 48 prior hours prior to onset of symptoms (or positive COVID test date for asymptomatic clients, whichever is earlier) and continues until the infected person meets release of isolation criteria.
Test Types
Rapid (antigen) Test - A Rapid (antigen) test will show whether someone has a high enough viral level to be potentially infectious now. Usually it takes 10-30 minutes to obtain results. These may be professional kits or at-home/ over the counter tests intended for individual use.
PCR Test - A PCR (polymerase chain reaction) test picks up traces of the virus for a long time, even if that virus is no longer transmissible. PCR tests may be positive for weeks after someone has recovered from COVID. Usually sent to a lab for processing. Anyone who has tested positive for COVID-19 may test positive with a PCR for up to 90 days and will be exempted from testing requirements.
CUE Test - a device, test cartridge, and nasal swab to deliver COVID-19 test results to an iPhone, iPad, or Android device (i.e., mobile app only) in 20 minutes.
