Recent Exposures and Close Contacts |
People who have a confirmed positive diagnostic test for COVID-19 must isolate for at least 5 days before returning to work or class. Day 0 is considered the first day of symptom onset or the day of your first positive PCR or antigen test. There are no exceptions or exemptions for isolation. Everyone who tests positive by either antigen or PCR testing—regardless of symptoms, previous infection, or vaccination/booster status—must isolate for at least 5 days. After you have completed isolation and have recovered from COVID-19, you do not need a negative test to return to work or class. Your isolation period may extend depending on the following:

What to Do if You've Been Asked to Isolate
Regardless of your vaccination/booster status, you should isolate yourself immediately and continue isolation from the date of your positive test unless you receive different guidance from your local public health authority or medical provider. Please use the isolation criteria listed above to determine the length of your isolation.
All CUIMC students must complete isolation as required before returning to work or class on campus. You cannot reduce the length of your isolation period, even if you later test negative for COVID-19.
Remain in Your Home or Room
Do not go out, except for emergencies or when recommended by a medical professional. If you must leave your home, try to do so during off-hours and avoid places where people are congregating. Additionally:
- Maintain distance (~ 6 feet or 2 meters) from others. If you must pass through a common space in your home, wear a mask and try to avoid common spaces if others are present.
- Arrange for groceries, items from a food pantry, or take-out food to be delivered to you.
- Consider laundry and dry-cleaning services that have contact-less drop-off.
- If possible, seek out someone who can assist you with getting packages or other deliveries from the lobby.
- Partners and spouses should not have shared sleeping arrangements during isolation or quarantine.
- If sharing a bathroom, the person who is isolating should clean and disinfect the frequently touched surfaces in the bathroom after each use.
- Do not use public transit.
- If you have a pet, be sure to have supplies and care for them too. Arrange for friends or professional services to walk your dog for you.
If you MUST go outside:
- Wear a face covering at all times.
- Maintain distance (~ 6 feet or 2 meters) from others.
Isolating in On-Campus Housing
If you are living in an on-campus apartment, you should stay in your private bedroom as much as possible. Wear a mask when entering shared spaces and wipe down high-touch areas with disinfecting wipes frequently.

- You are a resident of 50 Haven.

- If any of the following applies to you, please schedule a telehealth appointment with Medical Services via the Student Health Portal as soon as possible:

- You have an underlying health condition that puts you at higher risk for more severe illness.

If you are experiencing serious or critical symptoms (e.g., chest pain, shortness of breath, etc.), call 911 immediately.

Close Contacts
You can infect others with COVID-19 starting two days before any symptoms develop, or two days before your positive test, whichever is earlier. If you have been in close contact with anyone during your infectious period, you should notify these close contacts immediately, so they are aware and can take appropriate action.
In alignment with guidance from the New York State Department of Health, the University is no longer tracing contacts for most affiliates, but you can reach out to covidtesttrace@columbia.edu for additional support and guidance in navigating conversations for alerting your close contacts.
Definition of Close Contact
A close contact is defined as someone who has been within 6 feet for at least 10 consecutive minutes OR within 6 feet for at least 15 cumulative minutes over a 24-hour period of someone with a confirmed positive COVID-19 test during that person’s infectious period.
Notifying Close Contacts
If you have been in close contact with anyone during your infectious period, you should notify these close contacts immediately, so that they are aware and can take appropriate next steps.
- If the close contact is asymptomatic, regardless of vaccination/booster status:
- They do not need to quarantine.
- PCR testing is recommended no sooner than 5 days after they were last exposed. Asymptomatic close contacts who are Columbia affiliates can schedule testing with any off-campus facility that offers PCR testing. If a Columbia affiliate tests positive, they should immediately isolate and email results to covidtesttrace@columbia.edu for additional support and guidance.
- Continue to mask indoors where required and in crowded spaces outdoors and monitor symptoms over the next 10 days.
- If the close contact is symptomatic, regardless of vaccination/booster status:
- They should schedule a COVID-19 test as soon as possible and isolate while waiting for their results.
- Reinfections are possible with new COVID-19 sub-variants, so if a close contact develops new symptoms after recent COVID-19 infection (within the last 90 days, confirmed via PCR testing), they should obtain antigen testing and begin isolation if they test positive.
- Symptomatic contacts who are CUIMC students can schedule testing with any off-campus facility that offers testing, or with Student Health on Haven through the Student Health Portal (CUIMC students only).
- If their test is positive, they should isolate for at least 5 days and Columbia affiliates should email their results to covidtesttrace@columbia.edu for addtitional guidance and support.
- If their test is negative, they may return to work and class when their symptoms subside and should mask indoors where required and in crowded spaces outdoors and continue to monitor symptoms over the next 10 days.

Clinical Education
Clinical students concerned about exposures in clinical spaces should reach out to their program supervisors or preceptors for additional guidance in discerning close contacts that should be notified.
