Understanding Black Fungus: Symptoms, Causes and Treatment

The black fungus (also known as mucormycosis) is a growing problem, particularly for those recovering from COVID-19. If not treated and diagnosed early, this rare fungal disease can become a deadly and severe condition.

Studies have revealed that over 5 crore Indians suffer from serious fungal infections, with 10% of those suffering from the potentially deadly black fungus. The news has been filled with alarming reports of this hidden infection. Many of us are confused and concerned.

This article aims to provide you with a better understanding of black fungus, also known as Mucormycosis. We will explore the different types of black fungus, the causes and symptoms, as well as the treatment options.

What is Black Fungus, or Mucormycosis?

Mucormycosis is also known as Black Fungus. It is caused by a group fungi called’mucormycetes’. These fungi can be found in compost, soils, animal dung and decaying organic material. These fungi can enter the body in various ways, including through open skin wounds or inhalation.

Once inside the human body, these fungi can affect various organs including the brain, the lungs, the sinuses, the skin and the brain. The type and severity of the infection depends on the location of the entry and the overall health of the patient.

Black Fungus Types or Mucormycosis

Mucormycosis is classified into different types, including:

1. Pulmonary Mucormycosis: This form is more common in cancer patients or those who have had stem cell transplants.
2. Rhinocerebral Mucormycosis: This type is common in people with uncontrolled diabetes and kidney transplant recipients. It begins in the nasal cavity and can spread into the brain.
3. Cutaneous Mucormycosis: This form is most common in people who have not had their immune systems weakened. It occurs when fungi are introduced into the body by damaged skin caused by surgery, burns or other injuries.
4. Gastrointestinal Mucormycosis : This type is most common in young children and infants, especially those born prematurely or with low birthweight. It can also develop after surgery or from medication that reduces the body’s capacity to fight illness.
5. Mucormycosis Disseminated: A widespread infection that affects multiple organs and body parts, such as the skin, heart, and spleen. It spreads via the bloodstream.

Black Fungus and Mucormycosis: Causes

Inhalation of fungal spores can lead to infections in the lungs, brain or sinuses. The fungus may also enter the body via damaged skin caused by injuries, surgery, or any other type of skin trauma. Although microscopic fungi spores can be found in many places, they are not harmful to people with a healthy immune system. Inhaling fungi spores from mucormycete can cause infections in those with weak immune systems.

The fungi responsible for this infection are Rhizomucor and Mucor.

Black Fungus or Mucormycosis symptoms

The symptoms of mucormycosis vary according to the area of the body affected and can include:

• Fever
• Cough
• Chest pain
• Shortness of Breath
• Swelling of one side of the face
• Headache
• Sinus congestion
• Black lesions inside or on the nose bridge
• Abdominal pain
• Nausea and vomiting
• Gastrointestinal bleeding
• Blood in the stool
• Diarrhea
• Blisters, redness or swelling of the skin can be accompanied by pain or warmth.

If the infection spreads to the bloodstream in more serious cases, it may affect different parts of the human body, such as the heart and spleen. This can lead to mental changes or even a coma.

Let’s now explore the specific symptoms of each type Mucormycosis.

1. Lung Mucormycosis (Pulmonary)

You may experience the following symptoms if you have lung mucormycosis:

• Problem breathing
• Chest pain
• High fever (over 100.4degF)
• Bloody or dark liquids in the lungs
• Coughing up blood is a persistent cough
• Face swelling on one side

2. Sinus and Brain Mucormycosis

The following symptoms may be present in the brain and sinuses:

• Fever
• Headache
• Congested or swollen nose
• Face swelling on one side
• You may have black spots on the bridge of your nose or in your mouth.

3. Skin Mucormycosis Cutaneous

You might notice the following symptoms:

• Pain in the affected region
• You may have small, fluid-filled bumps on your skin.
• Infections or skin sores in certain parts of the face
• Darkening on the affected skin
• Heat, swelling, and redness around the infection

4. Gastrointestinal Mucormycosis

Symptoms of gastrointestinal mucormycosis include:

• Feeling nauseated and vomiting
• You may experience pain in your stomach or abdomen
• Gastrointestinal bleeding

5. Mucormycosis disseminated

It is difficult to diagnose because it occurs more often in people who have other health problems. It can cause mental or physical changes, including comas. You may also notice:

• Swollen eyelids
• You may experience weakness in the muscles surrounding your eyelids

Who is at risk of black fungus?

People with certain diseases or medical conditions are more susceptible to developing mucormycosis. This is due to a compromised immune system or the use immunosuppressive medications. Those at particular risk include:

• COVID-19 patients prescribed steroids
• People who have had stem cell or organ transplants
• Chronic illness can be a serious problem for those with it
• Uncontrolled diabetes is a serious condition.
• Low birth weight infants
• Premature babies
• Patients on immune-suppressing medications

Diagnosis for Black Fungus

Your doctor will ask you about your medical history if you are concerned about mucormycosis. Tell them if you have eaten bad food or been in places that had mold. They may take a sample of your nasal or throat fluid for testing if they suspect you have a sinus or lung infection. They may also need to take a tiny piece of infected tissues for testing. The doctor may also perform CT or MRI to determine if your infection has spread.

Treatment of Black Fungus

Antifungal medication must be taken promptly if you are diagnosed with mucormycosis. Amphotericin B is commonly prescribed, as are Isavuconazole and Posaconazole. These medications basically prevent the fungus’ growth, kill it, and manage infection.

You may have to swallow these medications or take them through a drip, depending on the severity of your condition. In severe cases, surgery may be required to remove the infected tissue or dead tissues and stop the spread of fungus. These procedures can cause disfigurement but are necessary to treat this potentially life-threatening condition.

Black Fungus Prevention

Mucormycosis can be reduced by taking certain precautions.

• Wear N95 masks to protect yourself from high-dust environments such as construction sites.
• Avoid contaminated water in areas prone to flooding and buildings that have been damaged by water.
• Avoid dust and soil if you have an immune system that is weakened. Protect your skin as necessary with clothing and wash any cuts and scrapes immediately with soap and warm water.

Closing Thoughts

It’s important that you follow the treatment plan prescribed by your doctor if you have been diagnosed with Mucormycosis. Do not hesitate to tell your doctor if you notice any side-effects or have concerns. If you have trouble breathing, get medical attention immediately.

We can all stay healthy and safe by learning the symptoms and risks of black fungus and how to prevent it, even in these difficult times.
