Fungal Infection

Dr. Puneet Madan    25-04-2022 Consult

A fungus is a primitive organism and the fungi can live everywhere in the air, in the soil, on plants and in water. Some fungi are helpful, while others harmful.

Fungal infections, caused by harmful fungi are very common and are not very serious if they are diagnosed quickly and correctly and treated. However, where fungal infections are concerned, once treated, reinfections can easily occur, as fungi can be a tad difficult to kill.

How does fungal infection occur?
Because fungal spores are often present in the air or in the soil, one can inhale the spores or they can land on a person. Thus fungal infections often start off in the lungs or on the skin.
People with weak immune systems are very prone to fungal infections.

Examples of fungal infections include:

- Tinea pedis (Athlete's foot)
- Tinea corporis (ringworms)
- Yeast infection
- Onychomycosis (Fungal Infection of the Toenails)

Who is prone to fungal infection?
Those who are prone to fungal infections include:

- People with weakened immune systems such as children, elderly people, people suffering AIDS, HIV infection, cancer, diabetes.
- People with a genetic predisposition toward fungal infections.
- People who sweat a lot since sweaty clothes and shoes can enhance fungus growth on the skin.
- People who come in contact with a person suffering from a fungal infection.
- People who frequent communal areas with moisture, such as locker rooms and showers, since fungi require moisture to grow and         reproduce.
- People who are obese as  they have excessive skin folds.

What are the causes of fungal infection?
Common fungal skin infections are caused by yeasts (such as Candida or Malassezia furfur) or dermatophytes, such as Epidermophyton, Microsporum, and Trichophyton. Fungal infection occurs when the fungal spores come into contact with the skin or are inhaled.

What are the symptoms of fungal infection? How is fungal infection diagnosed?
The symptoms of various kinds of fungal infections are as follows:

1. Tinea Pedis (Athlete's Foot)
- Peeling, cracking and scaling of feet.
- Redness, blisters/softening, breaking down of skin.
- Itching, burning or both.

2. Tinea Corposis (Ringworm)
- Itchy red ring shaped patch that can be scaly

3. Yeast Infection (Candida)
- Itching and swelling around vagina.
- Burning sensation/pain during urination or sexual intercourse.
- Redness and soreness in and around vagina.
- Unusual vaginal discharge.

4. Onychomycosis (Fungal Infection of Toe Nails)
- Nail discoloration.
- Nail flaking and thickening.


For fungal infections, you can consult a general practitioner or a dermatologist. Doctors usually diagnose the infection by scraping scaling skin off of a person and inspecting it under a microscope for evidence of any fungus.

What is the treatment for fungal infection?
For fungal infection, the doctor will treat you based on the type and of fungal infection, you suffer from, and also the severity of the condition. He may prescribe topical anti-fungal medication and oral drugs. Most fungal skin infections can be treated with over-the-counter or prescription creams.
