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.

As temperaturas e a gripe

As temperaturas e a gripe

A relação entre os factores climáticos (temperatura, humidade) e a gripe é o tema do artigo de Sander Van Noort, Gabriela Gomes, Ricardo Águas (todos do Instituto Gulbenkian de Ciência) e Sebastien Ballesteros (do Centro de Matemática e Aplicações Fundamentais da Universidade de Lisboa), publicado na 'Journal of Theoretical Biology'. Os autores analisaram os dados recolhidos pelo Gripenet, em Portugal, e pelos sistemas análogos da Holanda e Bélgica, bem como do sistema de vigilância EISN, no período 2003-2010.

Neste artigo descreve-se como as epidemias maiores são aquelas que acontecem em períodos mais frios. Analisa-se o efeito subtil (e não desejado) provocado por intervenções destinadas a reduzir a circulação de vírus, e que podem ‘deslocar’ a epidemia para períodos mais frios e, assim, acabar por causar mais casos de infecção gripal.
