STD Information: Yeast
Yeast infection, also known as candidiasis, is caused by a yeast overgrowth which disrupts normal vaginal flora. Certain yeast (candida) normally live in the vagina in relatively low numbers without causing a problem.
- Symptoms: burning &/or itching of the vulva, vagina; thick white discharge with cottage cheese appearance; possible yeasty odor.
- Transmission WTW: unknown, but not considered an STD in heterosexual couples.
- Treatment: anti-fungal creams, suppositories, or oral anti-fungals (tablets).
- Note: While recurrent or difficult-to-treat yeast vaginitis usually occurs in completely healthy women, occasionally it may be indicative of diabetes (undiagnosed or uncontrolled), HIV infection, or genital herpes, and should be fully evaluated — consult your healthcare provider. Sometimes yeast infections can be mistaken for allergic vaginitis, so recurrent yeast infections should be evaluated by a health care provider.
Please note that for the purpose of our web site we are focusing primarily on woman to woman transmission (WTW) and only providing a general overview of the infections themselves.
