What sexually transmitted disease is caused by a fungus?

Candidiasis, also known as a yeast infection, is caused by an overgrowth of the fungus Candida, particularly Candida albicans. While most sexually transmitted diseases (STDs) are caused by bacteria or viruses, candidiasis is unique because it’s primarily a fungal infection.

It typically occurs when the natural balance of bacteria and fungi in the body is disrupted. Factors like antibiotics, pregnancy, and a weakened immune system can lead to an overgrowth of Candida. Symptoms often include itching, discharge, and discomfort, particularly in the genital area. Understanding that candidiasis is linked to fungal etiology highlights the importance of recognizing its distinct nature compared to more common bacterial STDs such as gonorrhea, chlamydia, and syphilis, which are all caused by specific bacteria.
