Fungal Infection of the skin is also known as Mycosis. It is a mild disease, however, in some conditions, it can also lead to severe disease. It can affect anyone and can appear on any part of the body. Fungal diseases in humans are caused when an invasive fungus takes over an area of the body that the immune system cannot control. Different types of fungi can cause fungal infection and it can be contagious. The most common diseases caused by fungal infection are Athlete foot, Fungal nail infections, Ringworm, Vaginal candidiasis, candida infections on the mouth, throat, and oesophagus. There are several anti-fungal medicines available for fungal infection treatment.

What is Fungal Infection?

Fungal Infection is a skin disease caused by fungus. Just like microbes, there are two types of fungus – helpful fungus and harmful fungus.

Fungal infection is generally visible as it creates some patches or discolouration on the affected region. An infection caused by a fungus can be identified based on its appearance. In such conditions, it is necessary to consult a doctor and get it tested. If doctors are uncertain, they usually take a skin sample to inspect for the fungus. It is generally done to diagnose the type of fungus that has infected the area.

In some cases like yeast infection, the doctor may ask about the patient’s medical history and ask for a skin sample for test. They might also question if the person has taken antibiotics as it might also be the cause of infection.


After the diagnosis is done and the type of fungal infection is confirmed, the doctor will recommend a treatment, depending on the symptoms. A treatment includes – ointments for application on the skin, creams, anti-fungal medicines, tablets, and suppositories, as these are sufficient to treat maximum cases of fungal infection.
