COVID-19 Testing

Participate in large-scale testing for COVID-19

In the context of the lifting of the confinement, the Luxembourg government invites residents and cross-border workers to participate voluntarily in the free of charge large-scale COVID-19 testing.

The COVID-19 test (PCR throat swab) indicates whether the person being tested is contagious. By getting tested and respecting the recommendations of the Health Directorate (Direction de la Santé), the person helps reducing the total number of infected people to a minimum. This is the best way to break the chains of infection and to efficiently trace the contacts of the people infected (contact tracing).

Why should one get tested, even without showing any symptoms?

It allows to protect one's family, friends, colleagues and, last but not least, risk groups.

Important: A majority of those infected show little or no symptoms or are already contagious before showing symptoms. Hence, it may be that one carries the virus (and is therefore contagious) without knowing it.

Now that PCR tests are also available for people without symptoms, more infected people can be identified and the necessary measures to prevent other people from being infected can be taken as soon as possible. Every test helps to keep the pandemic under control. It is essential to collectively avoid having to take lockdown measures again that severely restrict our social and economic life.

Why is each person invited to be tested individually when other family members, friends or co-workers are not tested yet?

The large-scale testing strategy divides people into representative groups based on their work sector and their residential area. This means that within one’s family, one’s neighbourhood or among one’s colleagues, the invitations are deliberately delayed by several weeks. The underlying strategy is as follows: instead of testing the entire population at the same time, the objective is to ensure that every week someone in one’s environment is tested; this reinforces everyone's protection. Indeed, the test groups create, so to speak, a safety net that leaves virtually no room for the virus, and this for many weeks. The test becomes a gesture of solidarity, and allows to protect one another: "your test, our summer!"

What happens if the test is negative and the person is infected a few days later?

A negative PCR test does not mean that one is immune. A person can get infected later. Therefore, everyone, including those who test negative, should continue to observe the usual protective gestures. But thanks to the system of testing representative groups spread over time, the tests are not just a snapshot of the situation. The fact that there is always one person from a particular group being tested helps identify at any moment chains of infections to which that person may belong. Even if all new infections cannot be prevented, a second wave can be prevented collectively.
