Mucormycosis, commonly known as "black fungus disease," is a severe infection caused by Mucor molds naturally found in the environment. These fungi thrive in soil, decaying vegetation, and damp conditions. The infection typically begins with the inhalation of these fungal spores, affecting the sinuses and lungs, and can subsequently spread to the eyes, face, and central nervous system.
The primary cause of the disease is a weakened immune system. While rare in healthy individuals, the risk significantly increases in immunocompromised people. High-risk groups include individuals with uncontrolled diabetes, those undergoing cancer treatment, organ transplant recipients, people with HIV/AIDS, recent surgery patients, and those using immunosuppressive medications.
Notably, during the COVID-19 pandemic in India, a significant increase in mucormycosis cases was observed, suspected to be linked to the immunosuppressive effects of steroids used in severe COVID-19 treatment.
If left untreated, black fungus infection can spread rapidly and lead to life-threatening complications such as brain tissue infection, paralysis, pneumonia, seizures, and death.
