Quarantine, Isolation, and Vaccination Calculator

Use our COVID calculator to know when you are considered fully vaccinated, when and how long you need to quarantine, reinfection timeframes and more. Note: the isolation and quarantine portion of the calculator is still programmed at 10 days, not 5.

Isolation: When a person who is sick is asked to stay home and limit interractions with others, even those they live with. This includes anyone who tests positive and has symptoms, anyone who tests positive but has no symptoms, and those who have symptoms but have not been tested. 

Quarantine: When a person who is not sick is told to stay home because they have been exposed to someone who is sick.


The isolation and quarantine guidance on this page applies only to K-12 schools. To see guidance for other groups, click here



Students, teachers and staff who test positive for COVID-19 and/or display COVID-19 symptoms should isolate regardless of vaccination status and follow these instructions:

  • If your child tests positive for COVID-19 or they have symptoms of COVID-19 but do not get tested for COVID: Keep your child at home for 5 days*.
  • Your child can leave home and return to school after day 5* if their symptoms have improved (or no symptoms developed) and they have not had a fever for 24 hours.
  • They need to wear a well-fitted mask for 5 more days (in other words, through the end of day 10)*
    • If your child can't wear a mask while around others, your child should stay home for 10 days* before leaving the house and going back to normal activities
  • If your child tested negative for COVID-19, see the table below; your child can return to school based on their main symptoms or illness
  • Fill out this form to allow our nurses to provide you with better service.

*When counting days, day 0 is the day their symptoms started. Follow the same steps if your child tests positive for COVID-19 with no symptoms, counting day 0 as the date their test was done rather than from start of symptoms. For exposure, day 0 is the last day your child was around someone contagious with COVID-19.

If you are caring for someone with COVID-19

We know isolating at home can be difficult. If you need assistance with food, shelter, childcare, etc., we can help.


If your child was exposed to someone contagious with COVID-19:

  • Monitor your child for COVID-19 symptoms for 10 days*
  • Have your child wear a well-fitted mask around others for 10 days* after exposure
  • Avoid unmasked activities or activities with a higher risk of exposing vulnerable individuals
  • If possible, get your child tested for COVID-19 5 days* after they were last exposed and at any time they have symptoms of COVID-19
  • Contacts of a contact do not need to quarantine but should monitor themselves for symptoms
