What is influenza?
The flu or influenza is a specific viral infection caused by influenza virus. It is very contagious because it can be spread from person to person in secretions of the nose and lungs, for example when sneezing.

A lot of people are making a mistake by reffering to every respiratory infection as flu eventhough there are many other viruses causing similar respiratory problems.
Symptoms of influenza
A lot of people think that cold and flu are the same, but this isn’t true and flu symptoms can be much more severe. Influenza usually comes suddenly and may include the following symptoms:
- sore throat,
- nasal congestion
- higher fever,
- more malaise,
- severe body aches
Although other viruses may cause the same symptoms, they do so less commonly. The symptoms are usually mild to moderate in most people, but can be more severe in the elderly or very young children, causing thousands of deaths each year.
