Risk Factors

You are more at risk of developing community acquired pneumonia (CAP) if you:

  • Have a pre-existing illness or are having chemotherapy
  • Have recently had major surgery or are recovering from serious injury
  • Drink heavily - alcohol affects the white blood cells that are responsible for fighting infection
  • Smoke - smoking damages your lungs, making them more susceptible to disease
  • Have another serious condition that has weakened your immune system, for example chronic obstructive pulmonary disease (COPD), HIV, heart disease, emphysema, diabetes
  • Work in places where you breathe in a lot of dust, chemicals or pollution. This may damage your lungs making them more vulnerable to infections

Babies, young children and those over 65 are also at increased risk of developing CAP.

If you are worried about the risk of developing CAP, speak to your doctor who will be able to advise you.
