What Is Black Fungus, White Fungus And Yellow Fungus

In general, fungal infections do not hit individuals whose immune system is equipped enough to fight the pathogen.

According to the experts, these deadly fungal infections are not new or rare diseases and can even be detected in patients without covid-19.  In general, fungal infections do not hit individuals whose immune system is equipped enough to fight the pathogen. However, those with compromised immunity are more susceptible to the associated risks and complications.  Amid the Coronavirus pandemic, excess use of steroid, antibiotics, and other medications to treat severe covid-19 patients, comorbidities particularly diabetes,  weak immune system and poor sanitary conditions at hospitals treating COVID patients is attributed to the rise in life-threatening fungal infections.  In addition, the high mortality rate, the proportion of people affected, and shortage of antifungal medications makes black fungus, white fungus and yellow fungus scary and worrisome.

Let us understand these fungal infections in detail.

What Is Back Fungus Disease?

Black fungus disease or Mucormycosis is declared an epidemic in many states of India. Black fungus is not new and is a common cause of death in patients undergoing transplants or in ICU, particularly those with immunodeficiency. In Covid-19 patients rise in black fungus has been observed.

Besides white, black and yellow fungus recently, cases of nasal aspergillus have also have been reported. Pulmonary aspergillosis infection is observed in immunocompromised patients or after over use of steroids in the treatment of Covid-19 or by using non-sterile water for hydrating oxygen supplies. Although aspergillosis is not deadly it may be fatal if not treated timely. The fungus is very commonly found in environment and inhaled. In otherwise healthy individuals, it do not cause any infection but in immunocompromised and patients with lung diseases, it develops fungus related allergies reactions and lung infections. In severe cases, the infection may spread to blood vessels and prove to be fatal.

Can You Prevent Black Fungus, White Fungus And Yellow Fungus?

According to the experts, fungal infections are not contagious and cannot be spread from person to person or from animals to humans. However, it can spread from fungal spores present in the environment and air, which is almost impossible to avoid. Fungus and bacteria are already present in our body still; our immune system keeps them under check. However, when our immune system goes down due to overuse of steroids, immuno-suppressants, comorbidities or cancer treatment, these organisms get a perfect environment to multiply. The second wave of coronavirus infection has created a perfect environment for black fungus, white fungus and yellow fungus owing to low oxygen level, uncontrolled diabetes and commodity, excessive steroid and high intake of iron and zinc level along with lack of hygiene and prolonged hospitalization. Dr Nishant Kumar, an ophthalmologist at Hinduja Hospital, Mumbai, says, “There is lots of contamination in the pipes used for oxygen and the cylinders that are being used”. Thus, if you are on a ventilator and have been on tubes and oxygen for a long time in hospital, fungal infections get in. 

According to Doctor Randeep Guleria, Director, AIIMS, Delhi, specific preventive tips can prevent the onset of fungal infections in Covid-19 patients.

  2. Managing the blood sugar level among Covid-19 patients to manage the infection.
  3. Using a mask while dusting, sweeping or sitting in a dusty environment or even open air.
  4. Remove all the stale food and faecal matter to avoid fungal growth.
  5. Keep the surrounding clean and sanitized.
