Corona has involved people around the world with five mutations since about 19 months ago, and each mutation has created a new problem for people; in new variants, the problem of "black fungus" infection has darkened the face of this deadly virus.

Every time the virus changes, it increases the fear of people who are afraid of this uninvited guest. This time, black fungus affects people with low immune systems, diabetics and high blood pressure.Mucormycosis is a relatively acute and fatal disease caused by various mucosal fungi that has developed rapidly and has recently become known as "black fungus" due to Covid 19 disease.These fungi are abundant in nature and enter the body through the sinuses around the nose, eyeballs, bronchi, gastrointestinal tract or skin and reach the internal organs through the blood.All fungi in this category are not restricted to a specific geographical area and are distributed throughout the world. Biologically, these fungi grow rapidly in nature on decomposing sugars and wastes, and their spores are widely dispersed in the air.Therefore, it seems that humans all over the world are constantly in contact with the spores of this fungus.The disease cannot be transmitted from human to human or animal to human.Different forms of the disease depend on certain predisposing factors; For example, burns, surgery, and local or general disability are associated with the cutaneous form of the disease, malnutrition with the gastrointestinal form, acidotic diabetes with the nasopharyngeal form, and leukemia with the pulmonary form.These fungi are not pathogenic in normal state of a healthy immune system, but they can occur in the event of degenerative diseases such as diabetes, tuberculosis, burns, leukemia, and malnutrition that alter the immune system. Infections also occur following immunosuppressive therapies, such as long-term use of corticosteroids. Precautions include using masks in dusty areas, avoiding direct contact with water-damaged and decaying buildings, and protecting skin, feet, and hands in cases exposed to soil or manure such as horticulture or Some special outdoor work.In high-risk groups, such as those who have had an organ transplant, antifungal drugs may be prescribed as a preventative measure. Also, people who have been taking immunosuppressive drugs for a long time should be closely monitored for fungal infections.
