WHAT IS INFLUENZA?

Influenza - the flu - is familiar to all of us. It's so common, in fact, that we often forget how serious it can be.
Influenza is an acute viral respiratory infection. It spreads easily from person to person1; at home; at school; at work; at the supermarket; or on the train.

Each year, influenza causes 3 to 5 million cases of severe illness around the world1, with a large percentage of them being life-threatening. It is estimated that 10,000 deaths in England and Wales are attributable to influenza infections annually2. In the United States alone influenza results in an estimated:

  • 9.3 - 49

    million illnesses*

  • 17 million

    lost workdays^

  • 91 million

    lost schooldays~

Seasonal Influenza

Seqirus is on the front line of influenza protection, guarding against costly and life-threatening epidemics and pandemics. Vaccination is the most effective way to prevent influenza1.

Seqirus Global Presence

More dangerous than you might think

It's estimated that only about 1 in 18 children, 1 in 38 elderly and 1 in 45 adults3 who get influenza will seek medical attention, so the disease is likely to be much more widespread than we know.

Death from influenza is much more common among the elderly and the very young, but all ages are at risk for serious complications such as pneumonia, myocarditis, and inflammation of the brain or meninges.2

Our bodies and the influenza virus are in a never-ending race. As our immune system evolves to avoid infection, the virus adapts to evade our immune system. The new strains generally appear first in Southeast Asia then travel to the rest of the world. Influenza spreads best when temperatures and humidity are low, so the flu season coincides with the winter months in all different parts of the globe. This is why we need new influenza vaccines each influenza season - and why we are always working to stay ahead of the mutating virus.
