Facts about swine influenza

Swine influenza is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Swine flu viruses do not normally infect humans, however, sporadic human infections with influenza viruses that normally infect swine have occurred.

Surveillance and disease data

ECDC’s annual surveillance reports provide a wealth of epidemiological data to support decision-making at the national level. They are mainly intended for public health professionals and policymakers involved in disease prevention and control programmes.

Scientific advice

Systematic reviews, expert opinions and public health guidance on influenza in swine

Microbiology

Following the emergence of swine influenza A(H3N2)v viruses with sporadic human infections in North America, ECDC releases two technical reports assessing the capability of influenza reference laboratories in Europe to detect this novel virus.

Other types of influenza

2009 influenza A (H1N1) pandemic

The 2009 influenza A(H1N1) pandemic was declared over in August 2010 by the World Health Organization. Europe has now entered a new inter-pandemic phase of seasonal influenza.

Disease / public health area

Avian influenza

Avian influenza is an infectious viral disease in birds, including domestic poultry. Avian influenza is mainly found in birds, but under certain circumstances infections can also occur in humans even though the risk is generally very low.

Disease / public health area

Pandemic influenza

A pandemic is the rapid spread of a new human influenza around the world. Influenza pandemics happen when a new strain of a flu virus appears which can infect humans, to which most people have no immunity and which can transmit efficiently from human to human.

Disease / public health area

Seasonal influenza

Seasonal influenza is a preventable infectious disease with mostly respiratory symptoms. It is caused by influenza virus and is easily transmitted, predominantly via the droplet and contact routes and by indirect spread from respiratory secretions on hands etc.
