Influenzanet is a system to monitor the activity of influenza-like-illness (ILI) with the aid of volunteers via the internet
Flusurvey is an online system for measuring influenza trends in the UK.
In contrast to traditional surveillance methods, Flusurvey collects data directly from the general public, rather than via hospitals or GPs. This is particularly important because many people with flu don't visit a doctor so don't feature in traditional flu surveillance.
Anyone who lives in the UK can register to take part. When you register, you'll be asked to fill in a profile survey asking general questions about yourself and risk factors relevant to flu (for example, household size, age, and vaccination status). Each week, you'll be asked to report any flu-like symptoms you have experienced since your last visit. You can also take part on behalf of other people, for example household members. You'll be provided with the latest Flusurvey news and results, and regular updates on this season's flu epidemic.
The UK Flusurvey was launched on 16th July 2009, in the middle of the swine flu epidemic. It is part of a Europe-wide initiative to monitor influenza-like illness (ILI) activity.
Over 5000 people signed up in 2009. The Flusurvey has continued ever since, and is about to enter its 6th year.
The internet has been used to monitor patterns of influenza-like-illness (ILI) in the Netherlands and Belgium since 2003, in Portugal since 2005 and Italy since 2007. From 2011 France, Sweden, Spain, Denmark and Ireland are also running their versions of the Flusurvey.
