What is ‘The Flu’?

An extremely infectious acute respiratory illness, Influenza is caused by the flu virus. Affecting people of all ages, there are flu Outbreaks almost every year and on rare occasions reaching epidemic proportions. Because they usually occur in winter, these outbreaks  make it a seasonal infection.

However, for the very young and elderly people who are more vulnerable, flu can be severe and in some cases result in death. Serious respiratory complications can develop, including pneumonia and bronchitis, to which older people and those with certain chronic medical conditions are particularly susceptible.

Pregnant women also fall into the risk category of the complications of flu. Hospitalisation may be necessary for some people and recent statistics show that there are between 200 and 500 deaths, mainly in older people. as a result of influenza each winter.
