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.

Curvas de incidência
Legenda do gráfico:
Este gráfico mostra a progressão de um estudo sobre o impacto da vacinação na incidência da síndrome gripal. Há medida que a estação progride, o gráfico é actualizado semanalmente para reflectir qual a fracção de pessoas vacinadas contra a gripe (azul) e as não vacinadas (vermelho) que adoeceram com síndroma gripal numa dada semana. Para tal, colocamos os participantes do Gripenet nestes dois grupos (“coortes”), sempre (anonimamente) emparelhando alguém vacinado com alguém não vacinado mas de resto idêntico (mesmo grupo etário e factores de risco).
