Close Contacts & Contact Tracing

Close Contacts & Contact Tracing

Find out what to do if you are a close contact of someone with COVID-19!

Close contact means being within six feet for a total of 15 minutes or more over a 24-hour period, of someone with COVID-19 during their infectious period.

The infectious period is when the person with COVID-19 is contagious. It starts two days before symptoms began and continues until they are recovered. For people who haven't had symptoms, the infectious period starts two days before they had a positive test.

Close contact does not mean: being more than six feet away in the same indoor environment for a short period of time, walking by, or briefly being in the same room.

Close Contacts

If you are a close contact and not vaccinated, get tested as soon as 2 days after you were last in contact with the person, or as soon after that as you can. Find out where to get tested.

While Health Department contact tracers work to identify all close contacts, all might not be identified, or someone might know they are a close contact before they are reached. If you are a college student, your school may conduct contact tracing instead of the Health Department. 

If you think that you might be a close contact but were not notified, you may take precautions by quarantining for 14 days since the last day you were in contact with that person, and get tested on day 7 or after if you have not had any symptoms.

It can be stressful and overwhelming to learn you may have been exposed to COVID-19, but you can make sure your questions are answered and follow the health guidance to help prevent the virus from spreading. Here are more details on what to do if you’re a close contact.

If you had COVID-19 and are now a close contact of someone who tests positive, you do not need to quarantine if:

  1. you had a positive COVID-19 test result (from a PCR or antigen test) and have met the criteria to end your isolationand
  2. the new exposure is within the first 3 months after symptoms from your initial infection started, or within the first 3 months of your first positive test if you didn’t have symptoms during your initial infection, and
  3. you have not had any COVID-19 symptoms since the new exposure.

If you had your final dose of the COVID-19 vaccine and two weeks have passed and then you are a close contact of someone who tests positive, you do not need to quarantine unless you are an inpatient or resident in a health care setting or a health care worker in certain situations. 

Contact Tracing

If you test positive for COVID-19, a contact tracer will call you. They will give you guidance to stay home and away from other people until you recover. This stops the virus from spreading to other people. They will answer any questions you may have and see if you need help getting resources to stay home.

They will ask you questions about your symptoms, activities, and who you may have come into contact with during a specific period of time. This information is only used to prevent the spread of COVID-19. 

Based on your answers, the contact tracer will help you identify any close contacts. Those people may have been exposed to the virus, which means they have a greater chance of getting it themselves, and then of spreading it to others.

Here's how contact tracing for COVID-19 works in Vermont.

A contact tracer calling a person exposed to COVID-19If you are identified as a close contact, you will be contacted. The notification will come from the Health Department or a place you went to recently (for example, your employer, your college, your child’s school, or your health care provider might contact you). They will tell you the date when you may have been exposed. They will give you guidance to stay home and away from others for a certain amount of time. They will ask you to watch for symptoms and ask if you need help while staying home.

It’s important to answer the call and to answer questions as completely as possible to make sure everyone knows what steps to take to prevent the further spread of the virus. 

If you receive a text message from 86361, this is a notification from the Health Department that you are a close contact of someone who tested positive for COVID-19. Soon you will receive a call from a Health Department Contact Tracer. If you are a college student, your school may conduct contact tracing instead of the Health Department.

When to start and stop quarantine and isolation

Contact tracers use key dates to determine the amount of time you need to stay home. Your contact tracer will help walk you through this.

For people who test positive:

  • Symptom onset date – the first day you noticed symptoms. This is the date contact tracers will use to determine your timeline. (If you haven't had symptoms, contact tracers will use the date you got tested.)
  • Date of exposure – the date you were exposed to COVID-19. Contact tracers may not be able to know the exact date you were exposed, but they will narrow down the time period.
  • Incubation period – the amount of time it takes after being exposed, to when you first notice symptoms. If you didn’t get symptoms, the incubation is the period of time between exposure and when you test positive for COVID-19. The incubation period can range from 2-14 days after being exposed. Contact tracers will ask about your activities in the last 14 days to get an idea of where and how you may have been exposed.
  • Infectious period – the period of time when you have a high chance of spreading the virus to others, which means you were contagious. The infectious period starts two days before you get symptoms (or if you don’t have symptoms, the two days before you got tested) and continues until you have recovered. People you had close interactions with during this time are at risk and may be considered a close contact.
  • Isolation – the period of time where you will stay home and away from other people until you recover. Isolation starts as soon as you notice symptoms (or if you haven't had symptoms, it starts as soon as you get a positive test result).
  • End isolation – you can end home isolation when you have recovered. Generally, this means at least 10 days have passed since first noticed symptoms, symptoms have improved, and you are fever-free for 24 hours without taking fever-reducing medication. If you haven't had symptoms, generally, you can end isolation 10 days after you were tested.
