Seasonal influenza

Seasonal influenza is a vaccine-preventable disease that each year infects approximately ten to thirty per cent of Europe's population, and causes hundreds of thousands of hospitalisations across Europe. Older people, younger children and those with chronic conditions suffer the most, but everyone is at risk of developing serious complications—which include pneumonia, myocarditis and encephalitis—that may result in death.

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.

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.

Swine influenza

Swine influenza is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Influenza viruses that commonly circulate in swine are called “swine influenza viruses” or “swine flu viruses.” Like human influenza viruses, there are different subtypes and strains of swine influenza viruses.
