This is a post particularly for Dutch people… In Belgium and the Netherlands for the third time in a row there is an initiative to track influenza (’griep’) from around now till somewhere in April next year. So if you want to help the researchers out in getting a clearer view on how influenza develops and spreads, then sign up
on grotegriepmeting.be. Every week you will get an email asking you to fill out a couple of questions concerning any symptoms you might have had relating to influenza.

No, you won’t get sick by signing up ;).
Take care!
