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.

Epidemiología de la gripe
La gripe se transmite a través del contacto con personas enfermas. La vía fundamental de transmisión es aérea, a través de aerosoles o minúsculas gotas que contienen virus y que emiten los afectados al estornudar, toser o simplemente hablar. Estas, a su vez, entran en las vías respiratorias de la persona sana al respirar.
Dado que el virus puede sobrevivir un determinado tiempo fuera del huésped, el contagio también es posible cuando una persona sana toca una superficie previamente contaminada por el virus -por ejemplo, la piel de un enfermo- y después se toca su nariz o su boca.
Una persona infectada es infecciosa desde un día antes de comenzar los síntomas hasta siete (o más, sobre todo en niños) días después. Los síntomas suelen comenzar de uno a cuatro días después del contagio.
El hombre no es la única especie afectada por la gripe. Animales como aves, cerdos o caballos también son reservorios del virus y, eventualmente, el hombre podría contagiarse por ellos. La capacidad del virus para saltar de especie, unida a su alta variabilidad genética, hacen que la gripe no se pueda considerar hoy en día una enfermedad erradicable.
