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.

Influenzanet: a network of European citizens fighting against influenza

Influenzanet is a Europe-wide network to monitor the activity of influenza-like-illness (ILI) with the aid of volunteers via the internet. It is operational in eleven countries. In contrast with the traditional system of sentinel networks of mainly primary care physicians, 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.

Influenzanet featured on a special issue of the Journal of Infectious Diseases

Influenzanet has featured in a recent special edition of the Journal of Infectious Diseases, devoted entirely to studies on how to use big data to detect and model infectious diseases. In Europe, Influenzanet allows people in 11 countries to report influenza-like symptoms. This has been mentioned also in Nate Silver's blog: http://fivethirtyeight.com/features/how-new-york-hunts-for-early-signs-of-disease-outbreaks/
