InfluenzaNet is a system to monitor the activity of influenza-like-illness (ILI) with the aid of volunteers via the internet. It has been operational in The Netherlands and Belgium (since 2003), Portugal (since 2005) and Italy (since 2008), and the current objective is to implement InfluenzaNet in more European countries.

In contrast with the traditional system of sentinel networks of mainly primary care physicians coordinated by the European Influenza Surveillance Scheme (EISS), InfluenzaNet obtains its data directly from the population. This creates a fast and flexible monitoring system whose uniformity allows for direct comparison of ILI rates between countries.

Any resident of a country where InfluenzaNet is implemented can participate by completing an online application form, which contains various medical, geographic and behavioural questions. Participants are reminded weekly to report any symptoms they have experienced since their last visit. The incidence of ILI is determined on the basis of a uniform case definition.

Thank you to all of our participants!  Flusurvey is currently in hibernation for the summer.  Please check back here from time to time to see our latest results.  To read preliminary the most recent Flusurvey results:click here. Or, read about our findings on BBC news. Fortunately for Flusurvey participants there is still not much flu around. If you want to hear our new podcast: click here.

ILI Heatmap

Below see the amount of ILI reported around the UK right now.  The map shows a gradient from no reported ILI (blue) to very high ILI (red).  Currently there is not a great deal of ILI around. Map updated every three minutes.

National Science and Engineering Week!

Thank you to everyone who participated in National Science and Engineering Week (NSEW).  This year was a great success!
