Gripenet

Gripenet is a syndromic surveillance system that monitors the activity of influenza-like_illness (ILI), in near-real time, with the help of volunteers, via the Internet. This innovative surveillance system is based on the voluntary online participation of the population who, on a weekly basis, respond to an internet questionnaire about flu symptoms.

Any resident in Portugal can register by completing an online application form containing various medical, geographic, and behavioural questions. Every week, during the flu season, participants are asked to select from a list of symptoms the ones they have experienced since their previous visit to the website.

Moreover, the system includes a broad range of science communication and education activities and functions as an interactive project. This is ensured by team that includes experts on public health, mathematics, science communication, informatics, education and social sciences.
