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.

L'influenza stagionale
Il quadro clinico
In genere, l'influenza è descritta come l'insorgere improvviso di sintomi generali quali:
- tosse
- febbre superiore a 38°C
- dolori muscolari e/o mal di testa
Nel corso dell'infezione, oltre ai sintomi descritti sopra, fanno spesso la loro comparsa, anch'essi in modo improvviso, i seguenti sintomi clinici:
- sintomi generalizzati: brividi, sensazione generale di malessere debolezza, mancanza di appetito
- dolore alle ossa e alle articolazioni
- sintomi localizzati al tratto superiore delle vie respiratorie: congestione della mucosa orale, rinite, tosse secca
- sonnolenza - questo sintomi è raramente osservato tra gli adulti, mentre si osserva nel 50% dei casi tra i bambini di età inferiore ai 4 anni.
Neonati e bambini piccoli possono mostrare apatia, scarso appetito, difficoltà respiratorie connesse ad ostruzione nasale, sintomi gastrointestinali: nausea, diarrea e vomito.
Nel caso di assenza di complicazioni, le condizioni del paziente si normalizzano dopo circa sette giorni. I sintomi che persistono anche dopo questo periodo possono essere:
- tosse - fino anche a due settimane dopo
- continua sensazione di malessere e debolezza - specialmente tra le persone anziane già affette da malattie croniche.
