India is home to one of the world's heaviest fungal disease burdens; an estimated 57.25 million people (4.1% of the population) suffer from a serious fungal infection. From the everyday discomfort of ringworm and athlete's foot to life-threatening invasive aspergillosis, mucormycosis, and candidemia, fungal infections (collectively known as mycosis) span an enormous clinical spectrum.
Summer’s humid tropical climate, India’s high rates of diabetes, and large immunocompromised population create ideal conditions for fungal proliferation. This blog covers the types of mycosis, causes, symptoms, diagnosis, management, antifungal treatment, and when to seek specialist care at Artemis Hospitals, Gurugram.
What is Fungal Infection?
Fungal infections, collectively called mycoses (singular: mycosis), range from mildly irritating skin conditions to aggressive systemic diseases that carry mortality rates exceeding 50% even with treatment.
Superficial fungal infections are even more prevalent. Dermatophytosis (skin fungal infections like ringworm, jock itch, and nail fungus) affects 30–60% of people in India's hot and humid climate, according to dermatological data.
In Gurugram, where summer heat and humidity peak alongside dense urban living and shared amenities, fungal skin infections are among the most common presentations at Artemis Hospitals.
Understanding what causes mycosis, how to recognise it, and when basic self-management is insufficient are the foundations of protecting your skin, lungs, and overall health from this highly underestimated category of infection.
What Is Mycosis?
Mycosis is the medical term for any infection caused by a fungus. Most fungi are harmless and many are beneficial. The fermentation of bread, cheese, and certain beverages depends on fungi. The minority that infect humans do so either because they are inherently pathogenic (capable of causing disease in healthy people) or because they exploit a weakened immune system to establish infection.
The global death toll from fungal infections is significant: the WHO's 2022 Fungal Priority Pathogens List reported approximately 1.7 million deaths annually from invasive mycoses, a mortality burden comparable to tuberculosis and higher than malaria.
What are the Types of Mycosis?
Mycoses are classified primarily by the depth of tissue they affect. This classification directly determines treatment approach, prognosis, and urgency of medical intervention.
Superficial Mycoses
Affect only the outermost layers of skin, hair, and nails, without penetrating living tissue. Generally not inflammatory or painful primarily cosmetic concerns. Examples include tinea versicolor (pityriasis versicolor white or brown patches), tinea nigra (dark patches on palms), and piedra (fungal infection of hair shafts).
Cutaneous Mycoses (Dermatophytosis)
The most common fungal infections in India. Caused by dermatophytes fungi that feed on keratin and infect the skin, hair, and nails without penetrating deeper. Includes:
- Tinea corporis (ringworm of the body) circular, scaly, itchy patches on the trunk and limbs
- Tinea cruris (jock itch) red, itchy rash in the groin and inner thighs
- Tinea pedis (athlete's foot) peeling, cracking, itching between the toes
- Tinea capitis (scalp ringworm) hair loss, scaling, and itching on the scalp; predominantly affects school-age children
- Tinea unguium / Onychomycosis (nail fungus) thickened, discoloured, brittle nails
- Tinea manuum hand involvement, often co-existing with tinea pedis
- Tinea barbae beard and neck area involvement in men
Subcutaneous Mycoses
Affect the dermis, subcutaneous tissue, and sometimes bone. Usually result from traumatic inoculation thorns, splinters, or wounds introducing fungi directly into deeper tissue. Relatively uncommon in the general population but seen in agricultural and outdoor workers. Examples: sporotrichosis (rose-thorn disease), chromomycosis, mycetoma (madura foot a chronic granulomatous infection causing tissue destruction, particularly prevalent in parts of India, especially Rajasthan and Tamil Nadu).
Systemic (Invasive) Mycoses
The most serious category. Fungi infect internal organs, the bloodstream, the lungs, the brain, or multiple organ systems simultaneously. Can be primary (infecting healthy people) or opportunistic (occurring in immunocompromised individuals).
How Mycosis Develops?
Mycosis does not occur randomly. Understanding the causal pathways explains both who is at risk and why India's fungal disease burden is proportionally higher than in many other countries.
Sources of Fungal Exposure
- Environmental: Fungi are ubiquitous in soil, air, water, and decaying organic matter. Aspergillus spores are present in virtually all ambient air. Mucorales species are common in compost, soil, and decaying vegetation. Dermatophyte spores persist in shared changing rooms, swimming pools, and footwear.
- Animal contact: Tinea capitis in children is frequently transmitted from infected pets or farm animals. Sporotrichosis is associated with cat scratches.
- Human-to-human contact: Dermatophyte infections spread through direct skin contact, shared towels, footwear, and bedding.
- Endogenous overgrowth: Candida is a normal commensal organism, it causes disease when the balance of normal flora is disrupted (by antibiotics) or when immune defences fall.
- Healthcare-associated: Central catheters, endotracheal tubes, and broad-spectrum antibiotics are established vectors for candidemia and invasive aspergillosis in hospital settings.

How Fungal Infections are Diagnosed?
Accurate diagnosis is the foundation of effective antifungal treatment, and the weak link in India's fungal disease response. Many systemic mycoses are diagnosed late because their symptoms mimic bacterial infections, and because mycology laboratory capacity is limited in many parts of the country. The diagnostic approach varies significantly by the type of mycosis suspected.
For Superficial and Cutaneous Mycoses
- KOH (potassium hydroxide) wet mount: The most basic, accessible diagnostic tool. A skin scraping, nail clipping, or hair sample is treated with KOH to dissolve keratin, and the residual fungal elements (hyphae, spores) are visualised under a microscope. Fast, cheap, widely available.
- Fungal culture: The specimen is grown on Sabouraud Dextrose Agar (SDA) to identify the specific fungal species — important for treatment selection and epidemiology. Takes 2–4 weeks.
- Dermoscopy: Non-invasive, real-time skin examination to differentiate dermatophytosis from eczema, psoriasis, or other conditions with overlapping appearances.
- Wood's lamp examination: Ultraviolet light causes certain dermatophytes (particularly Microsporum species causing tinea capitis) to fluoresce — a rapid screening tool in clinical practice.
For Systemic and Invasive Mycoses
- Blood cultures: Standard first step for suspected candidemia. Specialised fungal culture media improve sensitivity. Positive blood cultures in a febrile patient should always include fungal cultures.
- Serum biomarkers: Beta-D-glucan (a fungal cell wall component) and galactomannan (specific to Aspergillus) are measured in serum and bronchoalveolar lavage fluid for early detection of invasive aspergillosis and other systemic mycoses.
- CT scan of chest: The CT halo sign (ground-glass opacity surrounding a nodule) and air-crescent sign are highly suggestive of invasive pulmonary aspergillosis in an immunocompromised patient.
- CT/MRI of sinuses and orbit: Essential for suspected mucormycosis — establishes the extent of sinus, orbital, and cerebral involvement and guides surgical debridement.
How to Manage Fungal Infections?
Management is grouped by severity: superficial infections are often manageable with topical antifungals and lifestyle modification; systemic infections require intravenous antifungal agents, sometimes for months, and in the case of mucormycosis, urgent surgical debridement.
Topical Antifungal Treatment
First-line for most cutaneous and superficial mycoses. Applied directly to affected skin for 2–6 weeks depending on the severity and location:
- Azoles: The most widely used topical antifungals for tinea corporis, cruris, pedis, and versicolor
- Allylamines: Fungicidal (kill rather than inhibit fungi) and typically require shorter treatment durations; particularly effective for dermatophytosis
Systemic Oral Antifungal Treatment
Required for nail infections (where topical penetration is inadequate), extensive skin disease, tinea capitis, and recurrent or resistant superficial infections:
- Allylamine antifungal medication (oral): Gold standard for onychomycosis and tinea capitis.
- Triazole antifungal medication: It is effective for dermatophytosis, Candida, and some systemic infections; also used as pulse therapy for onychomycosis
- Antifungal medication: The first-line treatment for vaginal candidiasis, oropharyngeal candidiasis, and Candida urinary tract infections; also used for cryptococcal meningitis maintenance
Surgical Management
For mucormycosis, surgery is usually essential. Doctors need to remove dead and infected tissue as quickly and completely as possible, along with giving strong antifungal medicines. If surgery is delayed or not done fully, the chances of recovery become much worse.
In some cases of foot mycetoma, surgery may also be needed to remove the infected area.
If mucormycosis spreads around the eye and becomes severe, doctors may need to remove the eye and nearby tissue to stop the infection from reaching the brain.
How to Prevent Fungal Infections?
Fungal infections can often be prevented with good hygiene and early care. Keeping the skin clean and dry, avoiding exposure to contaminated soil or water, and managing conditions like diabetes can greatly reduce the risk. People with weak immunity should be especially careful and seek medical attention if symptoms appear. Learn more below:
- Keep skin dry, especially in skin folds, between toes, and in the groin
- Change and wash socks and underwear daily
- Wear footwear in communal areas
- Do not share towels, combs, hairbrushes, nail clippers, or footwear
- Dry feet thoroughly after bathing, especially between the toes
For High-Risk Individuals
- Diabetics: Rigorous glucose control is the single most important preventive measure against mucormycosis, candidiasis, and dermatophytosis all are more frequent and more severe with uncontrolled blood sugar
- Hospital patients: Minimising unnecessary broad-spectrum antibiotics, early catheter removal, and meticulous hand hygiene reduce candidemia risk in ICU settings
- People with HIV: Maintaining CD4 count above 200 cells/µL through antiretroviral therapy is the most effective prophylaxis against PCP and cryptococcal meningitis
