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.

Attività influenzale in lieve ascesa

In Italia l'attività influenzale sembrerebbe aver cominciato la sua curva di ascesa. Vedremo nelle prossime settimane se la stagione influenzale sia davvero arrivata.

Anche nel resto d'Europa, secondo i dati riportati dalle nostre piattaforme gemelle di Influenzanet (, in accordo con quelli divulgati dall'ECDC (European Center for Disease Control), l'attività influenzale sembra in salita, e alcuni paesi, come Italia e Svezia riportano diffusione regionale dei focolai.

Sempre secondo i dati dell'ECDC, in questo momento il virus dominante tra i casi analizzati è quello tipo A, con il 95.5% (contro quelli di tipo B pari al 4.5%). Tra i virus di tipo A il ceppo pandemico A(H1N1) non e' quello dominante, presente solo nel 7.3% dei casi, mentre il restante 92.7% dei casi sono del ceppo A(H3N1).
