What is Black Fungus? How Black Fungus linked to Covid? What is the treatments?



Microcolonial black fungi are a group of ascomycetes that exhibit high stress tolerance, yeast-like growth and constitutive melanin formation. They dominate a range of hostile natural and man-made environments, from desert rocks and salterns to dishwashers, roofs and solar panels. Due to their slow growth and a lack of genetic tools, the underlying mechanisms of black fungi’s phenotypic traits have remained largely unexplored, Nature Scientific reported.


Later City News: Mucormycosis is a rare type of fungal infection that occurs through exposure to fungi called mucormycetes. These fungi commonly occur in the environment, particularly in leaves, soil, compost, and animal dung. Mucormycetes can enter the body through breathing, inhaling, and exposed wounds in the skin, Medical News Today reported.


There are different types of mucormycosisTrusted Source, including rhinocerebral (sinus and brain), pulmonary (lung), gastrointestinal, and cutaneous (skin) mucormycosis.


Respiratory-related symptoms include: cough, fever, headache, chest pain, nasal or sinus, congestion and pain, and shortness of breath.


Skin-related symptoms, which can occur in and spread to any part of the body, include: blackened skin tissue, redness, swelling, tenderness, blisters, and ulcers.


Mucormycosis is not contagious, and most people who come in contact with the fungi do not develop an infection. However, people with severely weakened immune systems are at increased risk of mucormycosis. This includes people with: diabetes, cancer, HIV, skin injury and surgery.


Doctors can treat the infection by administering antifungal medication or performing surgery to remove the affected area. If left untreated, mucormycosis can be fatal, with a mortality rate of 54%, according to the Centers for Disease Control and Prevention (CDC).


How Black Fungus linked to Covid-19?

States across India have reported more than 5,000 cases of the otherwise rare disease in recent weeks, mostly in people infected with COVID-19 or recovering from the disease.


COVID-19 has been associated with a wide range of secondary bacterial and fungal infections, but experts say India's second wave of COVID-19 has created a perfect environment for mucormycosis.


Low oxygen, diabetes, high iron levels, immuno-suppression, coupled with several other factors including prolonged hospitalization with mechanical ventilators, creates an ideal milieu for contracting mucormycosis, researchers wrote in the journal Diabetes & Metabolic Syndrome: Clinical Research & Reviews.
