Candidiasis is a fungal infection caused by Candida spp. {a type of yeast}. There are more than 20 types of Candida specie with Candida albicans being the most common. About three-quarters of women have at least one yeast infection at some time during their lives. Oral candidiasis is the most common fungal infection of the mouth. It is also the most common opportunistic oral infection in human.

It typically affects warm parts of the body such as;

  • Vagina
  • Mouth
  • Throat
  • Nail
  • Diaper region in babies
  • Folds under the breast Invasive candidiasis affects the blood, brain, heart and eyes.


Candida spp is a normal flora of the human body but the immune system of the body keeps its growth in check. Certain factors can increase ones chances of having an overwhelming growth of the fungi. They are;

1] *Recent use of antibiotics; this kills the body’s natural competitor of candida thereby increasing the growth rate of the organism.

2] Reduced immunity in conditions such as;

  • Recent prolonged sickness;
  • HIV
  • Chemotherapy
  • Old age
  • Diabetes
  • Steroid use
  • Use of immunosuppressive drugs; after organ transplant.
  • In children less than a month

3] Recent dentures

4] After sexual intercourse {usually for penile candidiasis} especially with an infected woman.

5] Poor sanitary practice and excessive douching; this has been found to increase the chances of having vaginal candidiasis.

6] Infrequent change of diapers in babies; prolonged exposure of a baby’s skin to urine and faeces increases the risk of having diaper candidiasis. The use of moist cloth nappies can also predispose to candidiasis.
