Mycosis refers to a fungal infection that can affect various parts of the body, including the skin, lungs, and other organs. It is caused by different types of fungi, which can enter the body through the skin, inhalation, or ingestion. Common types of mycosis include athlete's foot, ringworm, and aspergillosis. Symptoms of mycosis vary depending on the type and location of the infection. They may include itching, redness, and swelling on the skin, or respiratory issues if the lungs are affected. Treatment often involves antifungal medications, which can be topical or systemic, depending on the severity of the infection.
