Problems arise when it begins to multiply and creates an overgrowth. However, the majority of infections are caused by a species called Candida albicans.
Seventy-five percent of adult women will have a yeast infection at some point, according to the CDC. This rarely occurs in adults with healthy immune systems. Invasive candidiasis occurs when candida enters the bloodstream.

Quick treatment can help stop the spread of the fungus, while also improving, and potentially saving, your life. Candida skin infections can occur on almost any area of the body, but they are more commonly found in intertriginous regions. This is where two skin areas touch or rub together.

Normally, your skin acts as an effective barrier against infection. However, any cuts or breakdown in the superficial layers of the skin may allow the fungus to cause infection. Candida becomes pathogenic, or capable of causing disease, when conditions are favorable for it to multiply.
Hot and humid weather, poor hygiene, or restrictive clothing may produce these conditions. Candida infections also tend to be more prevalent in:.

Drying absorbent powders may help prevent fungal infections.
Antifungal skin creams, ointments, or powders may be used to treat a yeast infection of the skin, mouth, or vagina.

These so-called intertriginous areas can ooze, crack, or bleed, says AAFP, and as the skin breaks down, it becomes vulnerable to infection. Keeping skin folds cool and dry can help with healing and prevent recurrences, says AAFP.
As for treatment, NLM says options include antibiotic or antifungal creams, topical steroid cream, and drying agents such as antiperspirant or absorbent powder.
