|The common cold is an acute infection of the throat and nasal passages. It may be caused by several different viruses, the most common of which are rhinoviruses. The term 'common cold' refers to a set of symptoms, rather than a specific disease. Mild influenza may have similar symptoms to the common cold.|
For more information, see Common Cold.
|Influenza is an acute respiratory illness caused by the influenza viruses, which can be classified as type A, B, or C. Influenza is different from the common cold in that it causes a more severe illness, with fever, headache, significant fatigue and muscle aches. It is less likely to cause sneezing or a 'blocked nose' with thick nasal discharge.|
For more information, see Influenza.
Avian influenza (bird flu)
|Avian influenza, or bird flu, is an infectious disease of birds caused by type A strains of the influenza virus. There are several types of avian influenza. Those that cause infection and even death in humans are called highly pathogenic avian influenza (HPAI). Affected people are thought to have caught bird flu from direct contact with infected poultry.|
For more information, see Avian Influenza.
Swine influenza (swine flu)
|Swine influenza or swine flu, more correctly named H1N1 influenza A, contains a mixture of genetic information from viruses that normally infect pigs in Europe and Asia as well as from viruses which normally affect bird and human hosts. It is believed that this virus spreads mainly from person to person via coughing or sneezing by infected people.|
For more information, see Swine Influenza.
Cold or flu: Which do I have?

The human immune system
|The purpose of the immune system is to act as the body's defence against possible harm from toxins, bacteria, fungi, parasites and viruses. The human immune system is divided into two broad groups, called the acquired immune system and the innate immune system.|
For more information, see Human Immune System.
Acquired immune system
|The acquired immune system is responsible for the destruction of foreign particles once they have entered the body. During the first exposure to a foreign particle, the acquired immune system 'learns' how to attack and destroy it. A response to subsequent exposures can then be made more quickly and with greater force.|
For more information, see Acquired Immune System.
Innate immune system
|The innate immune system includes those parts of the immune system that work no matter what is causing damage to the body, and does not need a lot of preparation. The major defences of the innate immune system are those that stop the infection from getting into the body in the first place.|
For more information, see Innate Immune System.
Cold and flu prevention
Cold and flu can be prevented. The most important measure to prevent flu is to get vaccinated for influenza, but there are plenty of simple measures like healthy eating and hand washing that will help prevent you catching a cold or flu this winter.

|Flu vaccines are products given to people so that their immune systems are better able to recognise flu (influenza) infection, and therefore has a better chance of fighting it off. Flu vaccines work by exposing the immune system to tiny amounts of the inactivated flu virus, causing it to produce flu-fighting antibodies.|
For more information, see Influenza Vaccination.
