Fungal STIs are the most commonly occurring type of STI. They can be treated very easily. Fungal STIs can be treated with a full course of anti-fungal topical solutions and creams or a full length course of anti-fungal medicine. Fungal STIs are transmitted from one person to another through oral, vaginal or anal sex. Physical contact such as touching can also spread fungal STIs. Fungal STIs grow in dark, warm, and moist parts of the genital tract and also in armpits or on nipples.

Even after a fungal STI has been treated, a person should go to the doctor to make sure it has cleared up. If a person has a fungal STI, it is important that they finish the full course of treatment.

There are two STIs in this category: Tinea Cruris and Candidiasis

Tinea cruris

Tinea Cruris is a fungal infection of the groin. It grows and thrives in wet and moist environments. Tinea Cruris is more commonly known as ‘jock itch’ and is more common in males than females.


Genital/vulvovaginal candidiasis (VVC) is also sometimes called a “yeast infection” or “thrush”. It is a common infection that occurs when there is overgrowth of the yeast called Candida. Candida is always present in and on the body in small amounts. However, when an imbalance occurs, Candida can multiply. When that happens, symptoms of candidiasis may appear. Candida yeasts usually live in the mouth, gastrointestinal tract, and vagina without causing symptoms.
