Introduction
Recurrent vulvovaginal candidiasis (RVVC) affects millions of women worldwide, significantly impacting their quality of life. A recent study conducted in the tropical coastal region of Sanya, China, sheds light on key risk factorsincluding the role of previous antibiotic treatment—in the recurrence of these infections.

Uncovering the Study What the Data Says
This case-control study involved 728 women diagnosed with vulvovaginal candidiasis (VVC), divided into two groups:
- Non-Recurrent VVC (NRVVC): < 4 episodes/year
- Recurrent VVC (RVVC): ≥ 4 episodes/year
Using questionnaire surveys and clinical testing, researchers identified several contributing risk factors for RVVC.
Key Findings:
- Previous antibiotic treatment within 4 weeks increased RVVC risk significantly (adjusted OR: 4.41).
- Repeated abortions and vaginal lavage were also independently associated with increased risk.
- Showering twice daily was shown to be protective against recurrence.

Why Antibiotics Matter in Recurrenc
The overuse and misuse of antibiotics in Chinawhere nearly half of outpatient prescriptions include antibioticsmay disrupt normal vaginal flora, allowing Candida species like C. albicans to thrive.
According to The Infectious Diseases Society of America (IDSA), such disruptions can lead to persistent colonization and symptomatic infections that are hard to treat without long-term antifungal therapy.
The IDSA emphasizes the need for judicious antibiotic use and supports guidelines for managing recurrent fungal infections in women.
Candida Species Profile in RVVC
Cultures from patients with RVVC revealed:
- C. albicans (84.35%) as the dominant species
- Non-albicans species like C. tropicalis and C. glabrata were also found, which are often resistant to azoles
This highlights the importance of accurate diagnosis and treatment customization based on species identification
Hygiene Practices A Potential Shield
While many behavioral factors did not differ significantly between RVVC and NRVVC groups, showering more than once a day appeared protective.
Maintaining good hygieneespecially in warm, humid climatesmay reduce endogenous re-infection and contribute to prevention.
Clinical Implications and Preventive Steps
- Avoid unnecessary antibiotics: especially in women prone to yeast infections
- Limit vaginal lavage: as it disrupts healthy vaginal flora
- Emphasize preventive hygiene: such as frequent bathing in tropical settings
