Final answer:
The risk of recurrence of BV after treatment is around 30%. Higher hormone levels during pregnancy can disrupt the balance of the vaginal microbiota and lead to infections like BV. Topical treatment has a high success rate, but a small number of cases may experience recurrence.
Step-by-step explanation:
The risk of recurrence of BV after treatment is typically around 30%.
Higher levels of hormones during pregnancy can disrupt the balance of the vaginal microbiota and lead to infections such as bacterial vaginosis (BV). While topical treatment for BV has a success rate of 80-90%, there is still a possibility of recurring or persistent infections in a small number of cases.
If BV does recur, longer-term or intermittent treatment is usually effective in managing the condition.
