What is Mucormycosis (Black Fungus)?

The early symptoms depend on the area of infection. In case of infection in the nose, sinuses, and eyes – the earliest signs are nasal blockage, facial numbness, and double vision.

Some of the symptoms to look out for are:

• Sinusitis – nasal blockade or congestion, nasal discharge (blackish/bloody), local pain on the cheekbone
• One sided facial pain, numbness, or swelling.
• Blackish discoloration over the bridge of nose/palate Toothache, loosening of teeth, jaw involvement.
• Blurred or double vision with pain
• Fever, skin lesion; thrombosis & necrosis (eschar) Chest pain, worsening of respiratory symptom

No, Mucormycosis or Black fungus in humans is not contagious. People who are immunocompromised due to health conditions such as diabetes, cancer, or organ transplants are more at risk of this disease. Increased corticosteroid use during COVID -19 also weakens the immunity, which may make patients susceptible to Black Fungus.

Diagnosis of black fungal infection in the nose, sinus, and eyes is done through methods such as endoscopic examination of the sinuses and laboratory testing of the nasal tissue. This along with a CT or MRI scan can help clinch the diagnosis.

Yes, Mucromycosis is treatable.Treatment of Mucormycosis is a teamwork involving an ENT (Ear, nose ,throat ) specialist, ophthalmologist, neurologist and a radiologist. In advanced cases, surgery might be required along with antifungal medication such as Amphotericin B.

Some of the precautions one can take are:

• Periodic health checkups to monitor parameters such as blood sugar after recovery from COVID -19. 
• Usage of masks when in dusty environments such as construction sites.
• Wearing gloves and protective clothing while gardening or dealing with soil, manure or organic substances.

According to the Centers for Disease Control and Prevention (CDC), black fungus mainly affects people with health conditions or those on medications that weaken their immune system. Some of the factors that make a person prone to mucormycosis black fungus disease are: –

• Cancer
• Diabetes
• Organ Transplant
• Skin injury
• Excess iron in the body
• Low White Blood Cell (WBC) count
• Stem cell transplant
• Long term usage of drugs such as immunosuppressants and corticosteroids

With the increase in the number of black fungus cases, extra care needs to be taken. Experts say that there are certain precautionary measures one can follow during and after hospitalization for COVID-19 to minimize the risk of black fungus face infection. Here are some of the precautions one can take during hospitalization: –

• Keep diabetes and diabetic ketoacidosis under control.
• Prevent the usage of immunomodulating drugs.
• Stop using any antifungal medications.
• Minimize the use of steroids.
• Use sterile water for humidification while administering oxygen.
• Maintain good oral hygiene with povidone-iodine gargles and mouthwash.

Some of the precautions one can take post-hospitalization: –

• Keep your blood sugar level under control.
• Stay indoors.
• Focus on nasal and oral hygiene.
• Wear an N-95 mask when you go out.
• Maintain social distancing.
• Avoid going to places with a lot of dust.
• Avoid activities where you are in close contact with soil or manure (for example, gardening)
• Wear gloves, shoes, long trousers, long sleeve shirts when you go out.

With the rise on COVID-19 cases, black fungus epidemic has come across. This is so deadly that in certain cases, mucormycosis black fungal infection requires surgical intervention that may result in the loss of the upper jaw and sometimes even the eye. Black fungus patients would need to come to terms with the loss of function due to a missing eye or jaw. Prosthetic reconstruction will play a big role in rehabilitation after surgery.

Research is yet to check whether COVID-19 and mucormycosis nose infection are related in any way. However, most mucormycosis infections recorded in the initial waves of the COVID-19 pandemic in India have been in people who recovered from COVID-19.

Mucormycosis fungus, if not diagnosed, can be deadly. Also, because there is no black fungus vaccine. It enters the body and blocks the blood vessels, cutting off the blood supply to the tissues. Many cases of mucormycosis have been found in the upper jaw or maxilla, sometimes causing the entire jaw to detach from the skull. This usually happens because the blood supply to the upper jaw bone is cut off due to the fungus. The dead bone then detaches like a denture coming off.

The infection is so aggressive that it can spread faster than cancer. In about 15 days, it may spread from your mouth to your eyes and to your brain within a month. However, it should be noted that the infection is not contagious, meaning it does spread with contact.

The surgery performed is quite aggressive with the removal of infected tissues. For example, the eyeball, eye socket, oral cavity, or bones of the nasal cavity.

The symptoms of black fungus on skin include excessive redness, pain, warmth, or swelling of the wound.

White and black fungus are different from each other. Black fungus is a disease that affects the face, eyes, nose and brain. It may even cause loss of vision. While white fungus is far more dangerous as it affects the lungs and may damage other body parts.

Black fungus can be treated through surgery, where the infected tissues are removed. While to prevent white fungus, you need to maintain good oral health by regularly rinsing your mouth and brushing your teeth.
