  • Heterogeneous mucocutaneous disorder caused by infection with common commensal Candida species
  • Characterized by superficial infection of the skin, mucous membranes, and nails
  • >20 Candida species cause infection in humans. Candida albicans is most common, at 80% of isolates.
  • Candidiasis affects:
    • Aerodigestive system
      • Oropharyngeal candidiasis (thrush): mouth, pharynx (1)[A]
      • Angular cheilitis: corner of the mouth
      • Esophageal candidiasis
      • Gastritis and/or ulcers, associated with thrush; alimental or perianal
    • Other systems
      • Candida vulvovaginitis: vaginal mucosa and/or vulvar skin
      • Candidal balanitis: glans of the penis
      • Candidal paronychia: nail bed or nail folds
      • Folliculitis
      • Interdigital candidiasis: webs of the digits
      • Candidal diaper dermatitis and intertrigo (within skin folds)
  • Synonym(s): monilia; thrush; yeast; intertrigo

Vaginal antifungal creams and suppositories can weaken condoms and diaphragms.

Pregnancy Considerations
  • Vaginal candidiasis is common during pregnancy.
  • Topical treatment during pregnancy should be extended by several days (typically a full 7-day course).
  • Vaginal yeast infection at birth increases the risk of newborn thrush but is of no overall harm to baby.


  • Common in the United States; particularly with immunodeficiency and/or uncontrolled diabetes
  • Age considerations
    • Infants and seniors: thrush and cutaneous infections (infant diaper rash)
    • Women of childbearing age: vaginitis
    • Prepubertal or postmenopausal: yeast vaginitis
    • Predominant sex: female > male

Unknown—mucocutaneous candidiasis is common in immunocompetent patients. Complication rates are low.

Candida species are normal flora of oral cavity, pharynx, esophagus, and GI tract that are present in >70% of the U.S. population.

Etiology and Pathophysiology

C. albicans (responsible for 80–92% vulvovaginal and 70–80% oral isolates). Altered cell–mediated immunity against Candida species (either transient or chronic) increases susceptibility to infection (2)[A].

Chronic mucocutaneous candidiasis is a heterogeneous, genetic syndrome with infection of skin, nails, hair, and mucous membranes; typically presents in infancy

Risk Factors

  • Immune suppression (antineoplastic treatments, transplant patients, cellular immune defects) (2)[A]
  • Malignant diseases
  • AIDS or hematologic/immune disorders (neutropenia)
  • Corticosteroid use
  • Smoking and alcoholism
  • Hyposalivation (Sjögren disease, drug-induced xerostomia, radiotherapy) (2)[A]
  • Broad-spectrum antibiotic therapy
  • Douches, chemical irritants, and concurrent vaginitides alter vaginal pH and predispose patients to candidal vaginitis.
  • Denture wear, poor oral hygiene
  • Birth control pills, intrauterine devices
  • Endocrine alterations (DM, pregnancy, renal failure, hypothyroidism)
  • Uncircumcised men at higher risk for balanitis

General Prevention

  • Use antibiotics and steroids judiciously; rinse mouth after inhaled steroid use (1)[A].
  • Avoid douching.
  • Treat other vaginal infections.
  • Minimize perineal moisture (wear cotton underwear; frequent diaper changes).
  • Clean dentures often; use well-fitting dentures and remove during sleep.
  • Optimize glycemic control in diabetics.
  • Preventive regimens during cancer treatments (2)[A]
  • Treat with HAART in HIV-infected patients.
  • Antifungal prophylaxis against oral candidiasis is not recommended in HIV-infected adults unless patients have frequent or severe recurrences (2)[A].

Commonly Associated Conditions

  • HIV
  • Leukopenia
  • Diabetes mellitus
  • Cancer and other immunosuppressive conditions
