In case of contact with a covid-positive person 


High risk" and "low risk" contacts

You are considered "high risk" if, and only if

  • you have had at least 15 minutes of face-to-face contact with a Covid-19 positive person at a distance of less than 1.5 metres without at least one of the two people wearing a proper mask (nose and mouth);
  • you have travelled with a Covid-19 patient for more than 15 minutes within 3 seats of the infected person;
  • you have had direct physical contact with a Covid-19 patient.

You may be informed of a high-risk contact by a doctor, by the Contact Tracing Center, by the Quality of Life Service (students), by COHEZIO (staff) or by a person with Covid-19.

In other cases, you are a low-risk contact. Low-risk contacts do not have to comply with quarantine and do not have to undergo Covid-19 testing. They are, however, advised to watch for symptoms and to strictly adhere to barrier measures.

Procedure for fully vaccinated and asymptomatic "high risk" contacts (from 10 January 2022)

People aged 18 years and older are considered fully vaccinated if they have received their booster dose of Covid-19 vaccine, if they received the last dose of their basic vaccination less than 5 months ago, or if they have a valid certificate of recovery for less than 5 months. Persons aged 12-17 years who have received all doses of their basic vaccination are considered fully vaccinated, regardless of how long it has been since the last dose.

Under these conditions, "high-risk" contacts do not need to be quarantined, but must strictly adhere to barrier procedures for 10 days.

Procedure for partially vaccinated and asymptomatic "high risk" contacts (as of 10 January 2022)

People aged 18 years and older are considered partially vaccinated if they received the last dose of their basic vaccination more than 5 months ago and have not yet received their booster dose of Covid-19 vaccine.

In these circumstances, people should

  • observe a 7-day quarantine;
  • the quarantine can be lifted from the 4th day after the high-risk contact provided that a Covid-19 self-test is presented daily with a negative result from the 4th to the 7th day inclusive;
  • Strictly respect the barrier measures for 10 days.

Follow the procedure to inform your line manager and justify your absence from work.

Procedure for "high risk" unvaccinated and asymptomatic contacts (since 10 January 2022)

People aged 18 and older are considered unvaccinated if they do not meet the conditions for being fully or partially vaccinated (see above).

Under these conditions, people must :

  • observe a 10-day quarantine;
  • the quarantine can be lifted from the 7th day after the high-risk contact provided they present a daily Covid-19 self-test with a negative result from the 7th to the 10th day inclusive;
  • Strictly respect the barrier measures for 10 days.

Follow the procedure to inform your line manager and justify your absence from work.

How to perform a Covid-19 test following a "high risk" contact?

From 10 January 2022, people in quarantine (following a high-risk contact) who do not show any symptoms of Covid-19 should no longer perform a nasopharyngeal PCR test. They should use Covid-19 self-tests, which can be purchased in pharmacies, drugstores and some supermarkets.

Follow the procedure to inform your line manager and justify your absence from work.
