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.

Novo material para filtrar vírus da gripe

Novo material para filtrar vírus da gripe

Investigadores chineses desenvolveram um novo material destinado a máscaras faciais hospitalares e a filtros de aparelhos de ar condicionado. Objetivo: capturar os vírus da gripe, impedindo a sua circulação no ar e a entrada no corpo humano através dos olhos, nariz e boca.

Xuebing Li e colegas, da Academia Chinesa de Ciências, publicaram um artigo na Biomacromolecules onde descrevem a utilização de uma substância chamada chitosano, derivada da quitina, uma fibra natural que está presente na carapaça dos crustáceos. A combinação deste polímero com moléculas às quais os vírus Influenza se ligam para conseguir infetar as células-alvo resultou num material que captura eficazmente as partículas virais que o atravessam. Os vírus da gripe são partículas esféricas que têm um diâmetro interno de aproximadamente 110 nanómetros (nm) e um núcleo central de 70 nm. O nanómetro é uma unidade de medida 100 000 vezes menor que o milímetro.
