Fungal Infections: Causes, Symptoms and Treatments
A fungal infection, often known as mycosis, is a skin ailment caused by fungi. Fungal infections may afflict anyone and develop in various parts of the body. Such infections can be caused by a variety of fungi.
Fungi that aren't normally present on or inside the body can start colonising and cause illnesses in some situations. Fungi that are often present on or within the body can also proliferate out of control and cause an infection in certain cases. Fungal diseases can spread from person to person. In rare circumstances, the disease-causing fungus can be acquired via diseased animals or contaminated soil or surfaces.

- Dry, flaky, or scaly patches on the skin
- Swollen or blistered areas
- Thickened or discolored nails
- Cracked or peeling skin, especially in skin folds

Causes of Fungal Infections
Fungal infections are caused by various types of fungi that can infect the skin, nails, hair, and internal organs. Some Fungal infection causes include:
- Exposure to Fungi: Fungal infections are usually contracted by coming into contact with the fungus around warm, wet areas like locker rooms, swimming pools, and other shared areas.
- Weak Immune System: Individuals with compromised immune systems (e.g. people with HIV/AIDS, people with diabetes, people on immunosuppressive treatments) are at greater risk of fungal infection.
- Antibiotic Use :The use of antibiotics: because long-term antibiotic use allows the growth of naturally occurring fungi like Candida.
- Poor Hygiene: Not being hygienic, especially in areas like feet and groin, can lead to an environment where fungi can thrive.
- Diabetes: Elevated blood sugar levels can elevate blood sugar levels, leading to a weakened immune response and fungal proliferation, particularly on the feet.
- Moist or Damp Skin: Heat and moisture create ideal conditions for fungi, and if you sweat heavily or stay in wet clothes for a long time, it can lead to skin conditions such as athlete’s foot or jock itch.
- Contact with Infected People or Surfaces: Fungal infections, such as ringworm, are highly contagious and can be transmitted by skin-to-skin contact or touching infected surfaces, like towels, combs, or shoes.
- Environmental Exposure: Some fungi that cause systemic infections, such as Aspergillus or Histoplasma, are in soil or bird droppings and can produce severe lung infections when inhaled.
- Genetic disposition: Certain people may have a genetic disposition toward certain types of fungal infections, especially those with repeated episodes or long-standing conditions.
- High Antibiotic Use or Corticosteroids: Overuse or long-term usage of antibiotics or corticosteroids can alter the microorganisms in the body, increasing susceptibility to fungal infections.
Risk Factors of Fungal Infections
If treated promptly and effectively, fungal infections are typically not life-threatening. Those who are at a higher risk of contracting a fungal infection are listed below:
- People with weakened immune systems, such as children, elderly, and those suffering from AIDS, cancer, or diabetes
- People who are predisposed to fungal infections
- People who sweat a lot, since sweaty clothes and shoes might increase fungus development on the skin
- People who come in contact with a person who has a fungal illness
- Obese people with excessive skin folds
Complications of Fungal Infections
Fungal infections can have catastrophic consequences for people with weaker immune systems, such as those with AIDS or those using steroids or undergoing chemotherapy. These fungal infections are Superficial. This will not spread to the brain and heart.
Prevention of Fungal Infections
Maintaining good hygiene is essential for avoiding any type of fungal infection. Following tips may help you stay away from any such infections:
- Keep your skin clean and dry, especially in the creases
- Wash your hands frequently (particularly after contacting animals or other people)
- Don't use other people's towels and personal care items
- Clean up gym equipment before and after use
Diagnosis of Fungal Infections
Diagnosing fungal infections involves a combination of physical examination and laboratory tests. Initially, a healthcare provider will assess the symptoms and conduct a thorough physical examination of the affected area, looking for signs such as redness, rashes, or changes in the nails or skin. In cases of skin or nail infections, the doctor may inquire about recent exposure to public places or possible risk factors, like a weakened immune system or a history of antibiotic use.
For internal or systemic fungal infections, such as those affecting the lungs or bloodstream, doctors may use imaging techniques like X-rays, CT scans, or MRIs. Additionally, blood tests or tissue biopsies might be performed to confirm the presence of fungi in the organs. These diagnostic tools help determine the severity and extent of the infection and guide appropriate treatment strategies.
Treatment of Fungal Infections
These are the treatment options for fungal infection.
- Topical Antifungals: Such as clotrimazole, miconazole, or terbinafine, come in cream, ointment, or powder and are used for skin, nail, or localized fungal infections.
- Oral Antifungals: Oral antifungals like fluconazole, itraconazole or terbinafine are used for reactive or more severe fungal infections that fail to respond to topical therapy.
- Over-the-counter Treatments: For mild skin infections, over-the-counter antifungal creams or powders such as lotrimin or Monistat may be effective.
- Nail Fungus Treatment: Topical agents (ciclopirox, etc.) or oral drugs may be used for fungal nail infections. In more severe cases, nail removal may be required.
- Home Remedies: Some natural remedies like tea tree oil, apple cider vinegar, and garlic have antifungal properties and can help manage a mild infection.
- Probiotics: If fungal infections are due to an overgrowth of Candida, introducing probiotics into the diet may help restore balance to gut microbiota and prevent recurrent infections.
- Invasive Infection Treatment: For serious systemic fungal infections like candidemia or aspergillosis, potent antifungal drugs (e.g., amphotericin B, voriconazole) and extended treatment may be required in a hospital setting.
Lifestyle Changes and Self Care
- Shower frequently and properly
- Tight clothing, such as jeans, leggings, and jeggings, should be avoided. Wear comfortable cotton clothes.
- Don't share sheets, towels, or clothing.
- Dust, wet mop, or vacuum the house, and clean with soap and detergent to minimise fungal spore load in the immediate area.
- Remove any waistbands, wristbands, etc.
- If possible, use non-occlusive (open-loose) footwear such as sandals.
- Hair on the genitalia should be removed on a regular basis
- Maintain a clean scalp and do not share combs, hairbrushes, caps, or helmets.
- Surfaces that may be washed should be thoroughly cleaned with detergent soap and hot water.This should be done at least once a day for 4-6 weeks, or until the fungal infection is gone from all affected people.
