Yeast Infection Vs Fungal Infection: Know the Differences

Yeast Infection Vs Fungal Infection: Yeast infections are a form of fungal infection caused by an excess of Candida, a fungus that exists naturally on our skin and within our bodies, including the mouth, throat, stomach, and vagina. In a healthy body, yeast coexists with other microbes. However, if this equilibrium is broken, Candida can overgrow and cause illness. This is the primary distinction between yeast infections and fungal infections in general. Yeast infections target particular Candida-infested regions, whereas fungal infections impact a broader range of fungi and affect other sections of the body. The most prevalent variety is vaginal yeast infections, which cause burning, itching, and vaginal discharge alterations. In contrast, fungal skin diseases can manifest as rashes, patches, and irritation in warm, moist areas of the body like the groin, armpits, and between the toes.

Difference Between Yeast Infection and Fungal Infection

Yeast infections and fungal infections are both types of infections caused by microorganisms, but they differ in several ways. Outlined below are the differences between yeast infections and fungal infections:


Yeast Infection

Fungal Infection


Candida species

Various fungi species (including molds, dermatophytes)


Vagina, mouth, skin folds

Skin, nails, scalp, lungs


Itching, burning, discharge (in vaginal infections)

Rashes, scaling, redness, sometimes pain

Risk Factors

Antibiotic use, weakened immune system, hormonal changes, diabetes

Similar risk factors, plus environmental exposures, contact with infected individuals


Antifungal medications (e.g., azoles, topical creams)

Various antifungal agents depending on type and location


Not usually contagious, but can be transmitted through sexual contact or childbirth

Contagious depending on type and mode of transmission


Symptoms, microscopic examination, culture

Fungal cultures, skin scrapings, biopsies


Rare complications unless untreated or in immunocompromised individuals

Can lead to serious complications, especially in immunocompromised individuals


Good hygiene, avoiding douching, wearing breathable underwear

Avoiding contaminated environments, proper wound care


May recur in some individuals

Recurrence depends on type, underlying conditions, and treatment adherence

What is Yeast Infection? 

Yeast infections are a form of fungal infection that particularly refers to an overgrowth of yeast, usually Candida albicans, in moist parts of the body such as the vagina or mouth. This upsets the normal equilibrium of bacteria, causing symptoms such as itching, burning, and irritation.

Key Features of Yeast Infection:

  • Caused by an overgrowth of Candida albicans, a naturally occurring fungus in the body (particularly in the vagina and mouth).
  • Moisture-rich areas, such as the vagina, mouth (thrush), and skin folds, are particularly vulnerable. Itching, burning, redness, and discharge are symptoms of vaginal yeast infections, whereas white patches indicate thrush.
  • Antifungal creams, suppositories, and oral medicines are frequently used for treatment. They often resolve rapidly with adequate treatment.
  • Yeast infections are not sexually transmitted infections (STIs) and do not pass from person to person.

What is Fungal Infection?

On the other hand, fungal infections are a wider phrase that refers to any infection caused by fungus. This can range from simple yeast infections to severe systemic infections affecting many organs. Fungi can enter the body via the skin, nails, hair, or mucous membranes.

Key Features of Fungal Infection:

  • Caused by a broader range of fungus than Candida albicans. These fungi can be either exterior (athletes' foot or ringworm) or inside (lung infections).
  • They differ based on the nature and location of the illness. Common symptoms include itching, scaling, redness, and pain in the afflicted region. Internal fungal infections can result in fever, coughing, and difficulties breathing.
  • Treatment is determined by the type of fungus and its severity. It may include antifungal lotions, pills, or even intravenous drugs for severe infections.
  • Some fungal illnesses, such as ringworm, can spread through skin-to-skin contact or contaminated surfaces. However, not all fungal diseases are infectious.

Similarities Between Yeast Infection and Fungal Infection

  • Microorganisms from the Fungi kingdom produce both yeast and fungal infections.
  • Both forms of infections are normally treated with antifungal drugs, however the precise medication used may differ depending on the infection's nature and severity.
  • Risk factors for yeast and fungal infections may overlap, such as a weakened immune system, antibiotic usage, hormonal changes, and certain medical disorders such as diabetes.
  • While the symptoms of yeast infections and fungal infections differ, they may have certain characteristics, such as itching, redness, and pain, depending on the afflicted location.
  • Diagnostic procedures for both types of infections may include microscopic inspection, culture, or other laboratory testing to identify the culprit organism and provide suitable treatment.

Yeast infections are a particular form of fungal infection. Our bodies naturally have yeast, such as Candida albicans, in locations including the skin, mouth, and vagina. When conditions break the normal equilibrium, causing the yeast to overgrow, an infection occurs. Candidiasis is the medical word for what is usually known as a yeast infection. In contrast, fungal infections refer to a larger variety of infections caused by different moulds and yeasts. While yeast infections are common and treatable, fungal infections can vary significantly in severity and require different antifungal medications depending on the specific type of fungus. In essence, yeast infections are a subset of the wider group of fungal illnesses.

What is the difference between yeast infections and fungal infections?

Yeast infections are typically caused by Candida species, whereas fungal infections encompass a broader range of organisms including molds and dermatophytes. While yeast infections primarily affect mucous membranes and skin folds, fungal infections can affect various body parts including the skin, nails, and internal organs.

Are yeast infections and fungal infections similar in any way?

Yes, both yeast and fungal infections can result from imbalances in the body's microbiota, weakened immune systems, or exposure to environmental factors like humidity and poor hygiene. They may share similar symptoms such as itching, redness, and discomfort, and both can be treated with antifungal medications.

What are the common symptoms of yeast infections?

Common symptoms of yeast infections include itching and irritation in the genital area, pain or burning during urination or intercourse, and a thick, white vaginal discharge resembling cottage cheese.

How do fungal infections manifest on the skin?

Fungal skin infections often present as red, itchy patches with defined borders. In some cases, the affected skin may become scaly, cracked, or blistered. Fungal nail infections can cause thickening, discoloration, and crumbling of the nails.

Can yeast infections and fungal infections be prevented?

Yes, practicing good hygiene, avoiding excessive moisture in skin folds, wearing breathable fabrics, and maintaining a balanced diet can help prevent both yeast and fungal infections. For individuals prone to recurrent infections, prophylactic antifungal treatments may be recommended.
