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.

Gripe no mundo: a aumentar

Numa atualização virológica, divulgada na segunda-feira, a Organização Mundial da Saúde (OMS) observou o aumento global da atividade gripal nas últimas semanas de 2013, com o predomínio do vírus da pandemia de 2009, A(H1N1).

Os dados do relatório da rede FluNet, que cobre 99 países e territórios em todo o mundo, incluem testes laboratoriais a 88.471 amostras suspeitas. Destes, 17.640 (20%), revelaram-se positivos para o vírus da gripe.

Dessas 17.640 amostras positivas, 15.233 (86,4%) eram influenza A e 2.406 (23,6%) influenza B. Dos vírus influenza A subtipados, 6.889 (67,2%) eram H1N1 de 2009 e 3.365 (32,8%) eram H3N2. Dos vírus B, 352 (81,1%) eram da estirpe Yamagata e 82 (18,9%) da linhagem Victoria.
No que respeita à intensidade da epidemia, na América do Norte a atividade gripal aumentou drasticamente nas últimas semanas de 2013. O subtipo predominante do vírus da gripe foi o A (H1N1) pdm09.

Na China, a atividade gripal também tem vindo a aumentar, com a co-circulação de vírus A(H1N1) pdm09, A (H3N2) e Influenza tipo B.
