Today, Sciensano launches the 7th COVID-19 health survey. It addresses different aspects of our physical, mental and social well-being. The previous COVID-19 health surveys had between 20,000 and 40,000 participants! Once again, we count on your participation.

Fill out the survey 

The 7th COVID-19 health survey awaits you

Are you 18 or older and living in Belgium? Then complete our 7th online survey before the 21th of June. This will only take 15 minutes of your time and your participation really makes a difference.

The questionnaire is also available in DutchFrench and German.

Call for people of all ages, including the youngest ones (18-29)

Too few young people have participated in our latest surveys, yet this is important! Our surveys keep track of the health and well-being of all age groups throughout the coronavirus crisis. We need the help of young people as well!

Sharing is caring (also among young adults!)

Thanks for sharing our questionnaire as widely as possible among your friends, family and colleagues (who are 18 years or older and live in Belgium). We are counting on you!

The COVID-19 health surveys in short

These surveys support scientists and policymakers to assess the impact of the coronavirus crisis. Sciensano now launches a new questionnaire to:

  • monitor the evolution of recurring, important topics, such as mental and social well-being
  • assess a number of specific and current topics (this time we ask questions concerning your vaccination status and any side effects you experienced after getting your vaccine).

Thanks to your participation we can evaluate trends in time and study various public health topics.
