What is a Yeast Infection?

A vaginal yeast infection, also known as thrush or candida, is caused by a fungus, known by the scientific name vulvovaginal candiasis (VVC).
 

How are Yeast Infections Transmitted?

Yeast infections are not sexually transmitted diseases (STDs), but you may pass a yeast infection to your partner during sex. You do not have to be sexually active to get a yeast infection. Your vagina may have small amounts of yeast without causing symptoms. But when too much yeast grows, you can get an infection.
 

What are the Symptoms of Yeast Infections?

You may have itching and burning in and around the vagina, pain when urinating or during sex, and a thick, white vaginal discharge that looks like cottage cheese. It may be mild or severe.
 

How Do I Know if I Have a Yeast Infection?

A health care provider can examine the area in and around the vagina and test a sample of vaginal discharge. Yeast infection symptoms are similar to other vaginal infections and STDs.  If you have a more serious infection and not a yeast infection, it can lead to major health problems. Talk to your health care provider to learn more.
 

How are Yeast Infections Treated?

You can treat a yeast infection with anti-fungal prescription pills and non-prescription vaginal creams or suppositories. Tell your sex partners with symptoms of a yeast infection to get tested and treated to prevent getting a yeast infection again.
 

How Do I Prevent Yeast Infections?

Avoid douching because it can disrupt the natural balance of organisms in the vagina. Remove wet bathing suits immediately. Use cotton underwear. Keep the vaginal area clean. Always wipe from front to back after using the bathroom. 

Your risk for yeast infections increases if you are pregnant, have high blood sugar, have birth control with higher doses of estrogen, douche or use vaginal sprays, recently took antibiotics or steroids, or have a weakened immune system, such as from HIV.
