Contact Tracing

Due to the high number of infections, the functioning of Contact Tracing has been adapted:

From now on, people who are confirmed positive can self-report on

You have tested positive

In any case, self-isolate. Notify the people with whom you have been in close contact over the last 2 days and prepare a list with their names, telephone numbers and email addresses.

By an antigen self-test (Schnelltest):

  • Report your result on
  • You should immediately perform a PCR test to confirm your positive result. The prescription for the PCR test will be sent to you by e-mail within a few hours of your report.
  • If your positive result is confirmed by PCR, make the self-report on the same site or if you prefer, wait for Contact Tracing to call you.

By PCR/certified antigen test:

  • Once you have received the Contact Tracing reference number by SMS, declare yourself with the link provided in the SMS (
  • Report all your close contacts with their phone numbers, email or postal addresses, your last day at work, school or other, and the date of onset of your symptoms. (Be accurate and complete in your information, otherwise your report will not be validated and you will have to wait for Contact Tracing to call.)
  • As soon as Contact Tracing has validated your report (within 24 to 48 hours), your isolation prescription will be sent to you by e-mail. (Please check your junk mail regularly).

If it is not possible for you to self-report, you will be contacted by Contact Tracing as soon as possible, normally within 48 hours of your test result.

You have been in contact with someone who tested positive

If you have declared yourself as a close contact or if another person has declared you as a close contact, you will normally not be called by the Contact Tracing team.

  • If your email address is provided, you will in any case receive a prescription by email to perform a PCR test 6 days after the last contact with the positive person.
    • If you are not vaccinated or recovered, you will also receive a quarantine prescription. The quarantine can be ended on the 7th day, provided that a PCR test has been carried out on the 6th day after the last contact, and that this test is negative. For 7 days after the end of the quarantine, remember to self-monitor and wear a mask when in contact with others.
  • Should symptoms appear during your quarantine period or even after a negative test, you should immediately test and self-isolate without delay.
  • Further reduce social contact, observe protective measures and, if possible, work from home until your PCR test result is negative.
  • If you test positive, please follow the procedure above.

Your child has tested positive in primary school

You will no longer be called by Contact Tracing, as many tests are done at school, or parents notify the school, which provides a list of close contacts of a positive child to determine the scenario and therefore the measures that should be applied. Contact Tracing works closely with the MENJE team that receives the lists from the schools. Based on these lists, test orders are sent out and a quarantine for unvaccinated and un-recovered children is also sent.


What does it mean to have had contact with a COVID-19 positive person?

A distinction is made between protected contacts and close, direct contacts. 

In the context of the COVID-19 pandemic, as a general rule, close and direct contact occurs when two people, one of which has tested positive for COVID-19, have had face-to-face contact and in the absence of effective protective measures (without a mask, without respecting the rules of minimum distance, touching, shaking hands, kissing, etc.) for at least 15 minutes. 

A fortiori, a protected contact is a contact between two persons, including a positive COVID-19, during which the rules of protection have been observed and which lasts no longer than 15 minutes. 

While all contacts with an infected person are potentially risky, some are more risky than others. It all depends on how long and how close the contact is. Different contacts give rise to different measures. 

If you have had close and direct contact with a COVID-19 positive person, quarantine will be necessary. Vaccinated or recovered persons are exempt from quarantine in case of contact with a person who tested COVID+.

From the 6th day, after receiving a prescription, please submit to a COVID-19 test. If the test is negative, the quarantine is automatically terminated. However, should symptoms appear even after a negative test, you must immediately submit to a new test and go into isolation without delay. 

For 7 days after quarantine, consider self-monitoring and wear a mask when in contact with other people. 

For protected contacts, a 14-day self-monitoring period is sufficient.

Self-isolation or isolation apply to people who have a confirmed COVID-19 infection.​.

Isolation is prescribed by the physician for 10 days after the onset of symptoms. The duration of isolation is 10 days. Isolation may be terminated before the 10 days have elapsed for the following cases:

  • persons who received their full vaccination less than 6 months ago, or
  • persons who recovered from COVID-19 infection within 180 days of the positive PCR test, or
  • persons who received a booster vaccination

and if they perform SARS-CoV-2 rapid antigen tests on days 5 and 6 of isolation at the earliest. If the results are negative, isolation ends on day 6. 

It is a question of breaking the transmission chain.

How should I organise my isolation or quarantine?

Make a list of the basic items you will need during your isolation or quarantine (food, household products, prescription medicine, etc.) and have them delivered to your home.

If you do not live alone,  isolate yourself in a single room and use separate sanitary facilities (toilet and shower) if possible. If you do not have your own bathroom, make sure to disinfect the premises after use.

You should always wear a mask when leaving your room and wash or disinfect your hands regularly.

Members of your household should avoid entering your room and approaching you at all costs, even if they bring you food. They are advised to leave the tray in front of your bedroom door.

Remember to air your room regularly. Clean and disinfect frequently touched surfaces daily (tables, door handles, switches, counters, desks, telephones, keyboards, toilets, taps and sinks).

Use your own tableware, which should preferably be cleaned in the dishwasher, as the washing time and water temperatures there are more effective against the virus than when you clean your dishes by hand.

Use your own sheets, towels and clothes which should preferably be machine washed with laundry soap at a temperature of 60° to 90°C. Do not allow other members of your household to handle or carry your laundry. Place your dirty laundry in a watertight container.

Make sure to eat healthy food and drink enough water or herbal teas. Take your temperature regularly and call your doctor if you feel unwell. If you have severe breathing problems, call the emergency services.

Remember to keep a telephone or other means of communication nearby, as well as emergency contact numbers.
