Infections & Diseases

An overview of common infections and diseases


Athlete’s Foot

  • An infection of the foot caused by fungi.
  • We all the fungi that can cause athlete's foot on our bodies. They feed on dead skin cells and are usually harmless.
  • The fungi love warm, moist places and are primarily a problem for people who wear tight-fitting trainers or don't dry their feet properly.
  • The condition is communicable. It can be spread by direct skin-to-skin contact and indirectly through towels, shoes, floors, etc.
  • Symptoms include: A red itchy rash in the spaces between the toes and possibly small pustules. Often a small degree of scaling.
  • The infection can spread to the rest of the foot and other parts of the body.



  • It is a communicable condition.
  • It is called ringworm because the infection often appears as a round shape or ring. The general medical name for these infections is 'tinea'.
  • The infection often appears red or silvery, with scales, and is itchy. The edge is red and may be raised.
  • The ring spreads outwards and the centre may heal and go back to a normal skin colour.

Fungal Nail Infection

  • Causes of infections in toenails include wearing trainers or having hot, sweaty feet a lot of the time.
  • Fungi grow easily in warm damp environments.
  • The skin at the base of your nail can become damaged, and therefore more likely to become infected.
  • The nail often becomes thickened and discoloured. The nail can turn white, black, yellow or green in colour.
  • The nail can sometimes become crumbly, with pieces of nail breaking off, or even coming away from the toe or finger completely.

Influenza – The Flu

  • A viral disease which lasts from 3-5 days and can be followed by fatigue for 2-3weeks
  • Can cause: aching muscles and joints, headaches, coughing, fever, chills, runny nose, sore throat, vomiting and diarrhoea
  • It can become a much more severe illness, leading to pneumonia, nerve and brain damage and even death but such complications are rare.
  • It is possible to get vaccinated against influenza, which is especially advisable for the elderly and people with heart and lung diseases
  • Symptoms can be relieved by not smoking or drinking alcohol. Drinking lots of fluids can help and plenty of bed rest
  • A communicable condition which infects the nose, throat and lungs. Can cause an epidemic which lasts up to 6 weeks.


  • A long-term progressive disease of the lungs which causes shortness of breath
  • Lung tissue loses it’s elasticity causing the air sacs to lose their shape
  • Small air ways to the lungs collapse during forced exhalation
  • Sufferers cannot obtain sufficient oxygen nor can they rid the blood of carbon dioxide
  • Primarily caused by long-term exposure to air pollution or smoking

Chronic Heart Disease (CHD)

  • The UK’s biggest killer!!!

Results in approxim. 94,000 deaths per year

  • 1 in 5 men and 1 in 7 women die of CHD
  • The blood supply to the heart is stopped by fatty deposits in arteries
  • The fatty deposits are caller ATHEROMA
  • As the fatty deposits build up, the blood flow is slowed causing chest pain known as angina
  • If the coronary artery becomes blocked it can lead to a heart attack (myocardial infarction)
  • Lifestyle choices can reduce the risk of CHD


  • Cells in the body begin to grow and reproduce uncontrollable way
  • Often no specific symptoms are evident
  • The cells invade and destroy healthy tissue and organs
  • Most common in Uk are cancer of the: breast, prostate, lung, bowel and bladder.
  • Treatment can include surgery, chemotherapy and radiotherapy
  • More information on: Conditions, Cancer.
