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.

April Focus: participatory surveillance in Denmark

The Danish team of Influmeter recently published a paper assessing the first season of participatory surveillance for flu. They showed that Influmeter was useful in the timely monitoring of ILI activity in the Danish population compared with existing surveillance systems. Targeted enrollment of participants and exclusion of participants first or more reports are considered due to uneven representation of the underlying population.
