HOW YOUR SKIN BECOMES INFECTED?

Staph (short for ‘Staphylococcus auerus’) bacteria are the most common cause of skin infections. A variety of factors, including your immune status and the types of contact sport you play, can increase your risk of developing staph infections.10
 
Most bacteria are harmless, vital even, playing an important role in fighting infection and keeping us healthy.2 For example, beneficial gut bacteria help with digestion and immunity, making your body more resistant to disease, deriving as much benefit from you in return. However, when harmful bacteria become too colonised, a bacterial infection can occur.

FURUNCLE (BOIL)

  • Affects people of all ages5
  • Commonly found on the face, neck, armpits, buttocks and thighs but can appear anywhere on the body5
  • Symptoms include a swollen, red lump in the skin (sometimes, a hair will grow in it), painful to touch and filled with liquid or pus that may ooze out of a central ‘head’5
  • The boil itself is not contagious but the pus inside it is, particularly if it is oozing

FOLLICULITIS

  • Occurs anywhere on the skin where there is hair, frequently affecting adult men6,7
  • Commonly found on the neck, in the beard area, breasts, buttocks, back and chest.6,7
  • Hair follicle(s) become inflamed and infected and manifests as a tender pustule.6,7
  • While not usually contagious, prevent the spread of bacteria by not sharing razors and other personal items such as towels and washcloths.8

Infected wounds

  • Any wound contaminated with dirt or bacteria can get infected, especially deeper scrapes which tend to grind dirt into the skin, and puncture wounds8.
  • Wound pain that worsens a day or more after the injury often indicates the first sign of infection, and the wound may become red and swollen, ooze pus, and a fever may develop.8  While the wound itself is not contagious, to reduce the spread of bacteria to others, keep any cuts clean and covered.8

How is it treated?

Treatment usually involves antibiotics and drainage of the infected area.10 Topical antibiotics can play an important role in the prevention and treatment of many bacterial skin infections.3 Topical antibiotic creams and ointments, such as fusidic acid or mupirocin can be prescribed or recommended over-the-counter for bacterial skin infections such as impetigo, infected cuts and grazes, and infected dermatitis. Topical antibiotics work by stopping the growth of the bacteria causing the infection. These topical creams can also be used to prevent wound infections from occurring.3 Sodium fusidate (available as an ointment) is a salt of fusidic acid and it works in the same way.11 Your doctor or pharmacist will be able to recommend the appropriate product to treat your infection. In most cases, a bacterial skin infection does not cause serious harm. However, if left untreated, and the infection continues to penetrate even deeper it could enter the bloodstream, joints, bones, lungs or heart, and become dangerous.10
