COVID-19 Calculator

COVID-19 Isolation & Quarantine Calculator

We encourage you to use the Isolation and Quarantine Calculator on this page and use the resources listed below.

NOTE: These calculators are intended for the general public. Special populations living and working in higher-risk settings have separate guidance. This includes healthcare workers, individuals living in congregate settings, immunocompromised individuals, and schools. If you are in one of these categories, please review the specific guidance or contact the CDH Call Center at (208) 321-2222. Please follow your workplace, school, and childcare guidance if stricter than what is outlined in this tool.

K-12 students exposed in an instructional setting SHOULD quarantine from the community and follow their school's guidance on when to return. Click here for CDH's school resources page.

COVID-19 Contact Tracing Form

Seguimiento de Contactos COVID | Contact Tracing Form (SPANISH version)

CDH encourages the public to fill out the form if they, or their child, receives a positive COVID-19 test result. The form was developed with Adobe Document Signing to preserve HIPAA compliance in completing and sending.

Quarantine vs. Isolation

  • What is the difference between quarantine and isolation?
  • You quarantine when you might have been exposed to the virus. | CDC
  • You isolate when you have been infected with the virus, even if you don’t have symptoms. | CDC

When to seek emergency medical attention

  • Look for emergency warning signs* for COVID-19. If someone is showing any of these signs, seek emergency medical care immediately:
    • Trouble breathing
    • Persistent pain or pressure in the chest
    • New confusion
    • Inability to wake or stay awake
    • Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone
*This list is not all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you. Call 911 or call ahead to your local emergency facility: Notify the operator that you are seeking care for someone who has or may have COVID-19.

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. Anyone can have mild to severe symptoms. People with the following symptoms may have COVID-19:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

Three COVID-19 monoclonal antibody treatment facilities will be stood up in North Idaho, eastern Idaho, and the Treasure Valley. Monoclonal antibody treatment involves therapeutic medications that are proving to be effective in keeping people from getting severely ill and requiring hospitalization after contracting COVID-19. The centers will help preserve hospital bed capacity for the severely ill.

Specific information about the exact location of the treatment centers will be made available in the coming days. Additional treatment centers may be added later.

Patients visiting the treatment centers must have a referral from a doctor. The treatments are free.

Quarantine and isolation can occur concurrently in a household if all of the following are implemented:

Limit contact

  • The person who is sick should isolate
    • The sick person should separate themselves from others in the home.
    • If possible, have the person who is sick use a separate bedroom and bathroom.
    • If possible, have the person who is sick stay in their own “sick room” or area and away from others.
    • Try to stay at least 6 feet away from the sick person.
    • Shared space: If you have to share space, make sure the room has good air flow. Open the window to increase air circulation. Improving ventilation helps remove respiratory droplets from the air.
    • Avoid having visitors. Avoid having any unnecessary visitors, especially visits by people who are at higher risk for severe illness.

Eat in separate rooms or areas

Avoid sharing personal items

Wear a mask

  • The person who is sick should wear a mask when they are around other people at home and out (including before they enter a doctor’s office).
  • The mask helps prevent a person who is sick from spreading the virus to others. It keeps respiratory droplets contained and from reaching other people.
  • Masks should not be placed on young children under age 2, anyone who has trouble breathing, or is not able to remove the covering without help.


  • Put on a mask and ask the sick person to put on a mask before entering the room.

Clean your hands often

If you are unable to separate infectious persons from well persons in the household by following all risk reductions, it is important to implement as many of the risk reductions as possible. Household members will need to quarantine for 14 days after the infectious person is out of isolation which is the last known exposure date. See section on quarantine.

People you have been around during the two-day period prior to the start of your symptoms (or if you are asymptomatic, two days before your positive COVID-19 specimen collection date), through to the time you start isolation, are at greatest risk of infection and should be prioritized for notification.
