Fungal Diseases
Fungi are a distinct group of organisms that include yeasts, molds, and mushrooms. While many fungi are harmless or beneficial (like those used in baking or antibiotics), some are pathogenic and cause infections in humans. Fungi naturally thrive in warm and moist environments, which makes fungal skin infections highly common in tropical and humid countries like India.
Below is the detailed study of the most prevalent fungal infection in humans.
Pathogen | Disease | Transmission |
Candida albicans | Candidiasis (Yeast Infection) | Opportunistic infection; affects mucous membranes |
Trichophyton, Microsporum | Ringworm (Dermatophytosis) | Contact with infected soil, towels, clothes, combs |
Aspergillus spp. | Aspergillosis | Inhalation of airborne spores |
Ringworm (Dermatophytosis)
Pathogen:
The disease is caused by several genera of fungi, primarily Microsporum, Trichophyton, and Epidermophyton.
Mode of Transmission:
- Direct Contact: Skin-to-skin contact with an infected person or an infected animal (like a pet dog or cat).
- Indirect Contact (Fomites): Sharing contaminated personal items such as unwashed towels, clothes, bedsheets, or combs.
- Soil: In rare cases, it can be acquired by touching infected soil.
Affected Organs:
- These fungi feed on keratin, a protein found in the outer layers of the skin, scalp, and nails.
- They grow most actively in warm, moist areas of the body where sweat accumulates, such as the groin region, skin folds, and the spaces between the toes (a condition commonly called “Athlete’s foot”).
Symptoms:
- The infection typically presents as dry, scaly, and circular (ring-like) lesions on the skin.
- The outer border of the ring is usually red, raised, and inflamed.
- These lesions are accompanied by intense and persistent itching. In cases of scalp infection, it can lead to patchy hair loss.
Treatment and Management:
- Ringworm is highly curable.
- Medical treatment involves maintaining strict personal hygiene, keeping the affected area completely dry, and applying topical antifungal creams or ointments (such as Clotrimazole or Terbinafine).
- In severe or widespread cases, oral antifungal tablets are prescribed by doctors.
Public Health Context:
- Because ringworm is rarely life-threatening, the government does not run a standalone vertical program exclusively for its eradication (unlike TB or Polio).
- However, its prevention is directly linked to the Water, Sanitation, and Hygiene (WASH) principles promoted under the Swachh Bharat Mission (SBM).
- Free diagnosis and antifungal medications are provided at the grassroots level through the extensive network of Ayushman Bharat – Health and Wellness Centres (AB-HWCs) across the country.
