Chest infection

Chest infections include a variety of illnesses ranging from mild respiratory illness to life-threatening conditions including:

  • acute bronchitis - inflammation of the airways due to infection
  • making worse chronic obstructive pulmonary disease (COPD)
  • community-acquired pneumonia ie caught outside of hospital
  • pleurisy - infection of lung linings

Chest infections are very common. Often a specific cause cannot be identified but bacteria and viruses are usually responsible.

Factors which make people more prone to chest infection include:

  • other lung conditions such as asthma, bronchitis, cystic fibrosis,
  • reduced immune systems and therefore lowered resistance to infection eg people with cancer, diabetes, heart problems,
  • reduced mobility,
  • smoking,
  • exposure to environmental factors eg Legionnaire’s disease, a form of pneumonia caused by bacteria in water,
  • exposure to animal germs eg the rare condition psittacosis (parrot fever) caught from infected birds, and
  • chest surgery which carries a risk of post-operative infection.
