What is Black fungus? Why it's affecting COVID Patients?

Black fungus

 Mucormycosis or black fungus is an infection that affects the individuals whose immune system is not functioning properly. It develops black colour colonies in infected areas. 

It is present mainly in soil & decomposed waste as fungal spores and spread through soil & air. These fungal spores enter into the body either through inhalation/ingestion or in rare cases enters the body through a wound.

Therefore It's impossible to avoid the infection but our body has a strong defense system to fight against this fungal disease. Hence you need not worry much if you're immunocompetent.

Black fungus is non contagious, doesn't spread from humans to humans or from animals to humans . It's a rare infection but a very serious condition. It mainly affects lungs and brains. It poses a threat in patients with weak immune systems.

  • Individuals with habits like Tobacco chewing,smoking, and alcohol are also susceptible.

  • Patients on ventilator support and  continue use of nasal prongs & a mask.

What are the Symptoms ?

Black fungus symptoms vary depending upon the infected area on the body. If your skin is infected then the particular area will be swollen with painful red blisters which may turn into black. Through blood this fungal infection can spread to other organs in the body like spleen, heart etc.If it happens then the individuals may experience several changes & fall into coma,it can be fatal in some cases.

Why Black fungus infections increasing in most of the COVID Patients?

Not all the Covid Patients are susceptible to this infection but only few are infected due to the following factors-

  • Weak immune system 

  • Use of drugs like steroid which reduce the number of white blood cells(WBC defends our body from harmful infections)

  • Excess use of zinc,which acts as catalyst for fungal growth.

  • Treatment with excess Antibiotic drugs

  • Prolonged use of oxygen, especially industrial oxygen, is also one of the causes of black fungus where the steam creates a favorable  environment for the growth of fungus around nose and mouth areas.


Black fungus is treated with antifungal drugs in the early stages & a surgical process also needed to remove the tissue in some severe conditions.
