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 launches on Wednesday 19th November 2014 for the 2014/5 flu season. We look forward to your engagement with this project this year, as in previous years.  

This year we are pleased to announce an exciting collaboration with i-sense, an £11M EPSRC funded interdisciplinary research collaboration led by University College London to develop early warning sensing systems for infectious disease. 

We have some exciting things in the pipeline being developed with i-sense collaborators: 

Some participants this year will be able to take part in a self-swabbing exercise to see if the influenza-like symptoms that they report are being caused by a flu virus or something else. 

We are also going to combine aggregated data from Flusurvey weekly symptoms surveys with that from social media and internet searches allowing flu trends to be monitored more accurately and earlier than ever before. 

Finally i-sense researchers at UCL will be using Flusurvey data to develop a mobile app which will provide up to the minute information about flu hotspots. 

More information about all these developments will be available shortly - watch this space!
