A Comprehensive Overview of Candida albicans as the Leading Pathogen in Vulvovaginal Candidiasis

Candida albicans is the primary etiological agent of vulvovaginal candidiasis (VVC), a widespread fungal infection affecting millions of women worldwide. Although often self-limiting, VVC can become recurrent or severe, significantly impacting quality of life. The pathogenesis of C. albicans is driven by key virulence factors, including hyphal transformation, biofilm formation, and immune evasion, which all facilitate persistence and resistance to host defenses. Epidemiological data indicate that up to 75% of women experience at least one episode of VVC, with 5-10% developing recurrent vulvovaginal candidiasis. The condition typically presents with vaginal itching, burning, erythema, edema, and an abnormal discharge. Diagnosis relies on both clinical presentation and microbiological confirmation; however, misdiagnosis remains common due to symptom overlap with other vaginal infections and conditions in general. Azole antifungals remain the cornerstone of treatment; however, increasing resistance (particularly in non-albicans Candida species) poses substantial therapeutic challenges. Consequently, the emergence of antifungal-resistant strains underscores the need for novel treatment strategies, including probiotics and natural antifungal agents. Preventive measures-including maintaining vaginal microbiota balance, avoiding unnecessary antibiotic usage, and improving hygiene practices-play a pivotal role in reducing disease burden due to C. albicans. Given the rising incidence of VVC and the burden of recurrent cases, further research is essential to develop targeted therapeutic interventions. This comprehensive review highlights the evolving epidemiology, pathogenesis, and clinical challenges of C. albicans-associated VVC, emphasizing the need for improved diagnostic strategies, alternative therapeutic approaches, and targeted preventive measures to reduce disease burden and enhance patient outcomes.
