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.

About the Flusurvey

Flusurvey is an online system for measuring infectious diseases trends in the UK. The system is now used to monitor flu and coronavirus 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 who may be harbouring some infections/diseases don't visit a doctor so don't feature in traditional disease 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 some diseases(for example, household size, age, and vaccination status). Each week, you'll be asked to report any related 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.

Participation is entirely voluntary, and information is collected for research purposes only. All analysis is carried out on anonymous datasets. For more information about how we handle data provided by Flusurvey participants, please see our privacy policy.

History of Flusurvey

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.

Flu surveys in other countries

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.
