Causes and Treatment of Skin Infections

" To take hold, skin infections need to penetrate the skin, which is the largest and most visible organ of the body. It functions as an anatomical barrier between the internal and external environment. As such, it protects the body from pathogens (harmful organisms) and other substances in the environment. Although there are millions of bacteria, yeast and other microorganisms normally found in the human skin, skin infections occur only when there is a disturbance in the integrity of the skin or when the immune system is weakened."  


A skin infection occurs when the skin is invaded by harmful microscopic organisms like viruses, bacteria, and fungi, where they multiply and cause subsequent tissue injury, which may progress to disease. A break in the skin, such as a wound increases one’s risk for a skin infection. Other factors, such as poor hygiene, presence of a systemic disease, or weakened immune system also increase one’s likelihood for acquiring an infection on the skin surface.

The most common causes of infection includes:

  • Viruses, such as Herpes simplex virus (HSV), Herpes zoster, human papillomavirus (HPV), and Molluscum contagiosum

To identify the pathogen causing an infection, a clinical skin examination is initially done, followed by laboratory examination of specimens obtained from skin scrapings, pus or exudates (fluid from the lesions). Microscopic examinations may involve the use of staining techniques and culturing methods to identify microorganisms. Ultraviolet light (Wood's lamp) may also be used for fungal infections. .


Most types of infection are characterized by erythema (redness), edema, and other signs and symptoms of inflammation. These may include itching, scaling, and pain.Focal accumulation of pus or fluid may develop. Alternatively, there may be no signs of inflammation. Other appendages of the skin such as the nails and hair follicles may be affected, causing discoloration and thickening of nails, inflammation of hair follicles and hair loss.

Infection may be localized or widespread, depending on the cause, and symptoms may vary from an inflammation confined to a small area of the skin or may involve the rest of the body, causing fever, malaise and inflammation of lymph nodes.


Local infections on the skin are treated by repeated cleansing using soap or detergent, which contain an antimicrobial agent. Topical antiseptics like chlorhexidine may be used to eliminate the source of infection and prevent its spread to adjacent skin area or to other individuals.

Drying agents like aluminum chloride may be used to inhibit the overgrowth of other opportunistic microorganisms.

Keratinolytic agents like topical salicylatesare used to remove thick skin lesions that may harbor pathogens and to expose the infected skin surface to other local treatments.

Topical antimicrobial agents (antibiotics, antiviral and antifungal agents) are often used, but systemic therapy (oral or injected) may be needed for patients with more extensive skin disease.
