Fungal infection

At a Glance

Fungal infection (mycosis) refers to infectious diseases caused by fungi, ranging from mild skin infections to very severe infections.

Representative clinical presentations include forms occurring in the skin or mucous membranes, such as athlete's foot, nail infections, and yeast infections, as well as forms that can originate in the lungs.

How the Disease Works

Fungi exist in air, soil, plants, water, etc., and can cause infection after inhaling spores or coming into contact with the skin.

When the infecting fungi proliferate in the skin, mucous membranes, or internal organs, tissue damage and immune responses occur, and the presentation varies depending on the site of infection and immune status.

Patterns Vary by Person

The risk of fungal infection may increase in individuals with a weakened immune system or those taking antibiotics.

Broad framework of diagnosis and management

Symptoms may manifest as itching, rash, pain, discharge, cough, fever, etc., depending on the site of infection, and may remain as a localized infection or, rarely, progress to a systemic infection.

Diagnosis is performed after evaluating lesions and symptoms, using a combination of microscopic examination, culture, molecular testing, or imaging of skin, fingernail/toenail, or respiratory specimens as necessary.

Current stage of treatment

Since a positive test result alone does not determine the severity of the infection or the necessity of treatment, the symptoms, site of infection, quality of the specimen, and immune status must be interpreted together.

Management is carried out by identifying the infection site and causative fungus, and, if necessary, coordinating antifungal treatment with local hygiene measures alongside the management of underlying diseases and immune status.

For skin and nail infections, topical antifungals may be used, and for more severe infections, oral antifungals may be considered.

How to read clinical trials

In follow-up observations, changes in symptoms and test results, treatment response, and side effects must be assessed together, and it should not be concluded that treatment efficacy, safety, regulatory approval, or standard-of-care status has been established solely based on a clinical trial's enrollment or completion.

Points to verify in clinical encounters

In clinical practice, it is important to assess the onset time and location of symptoms, recent use of antibiotics/immunosuppressants, underlying conditions and immune status, current medications, tests performed, and follow-up plans.
