Have you ever heard of black fungus? This hidden disease is a growing concern, especially for people recovering from Covid-19. This disease is known as mucormycosis, and it is a rare serious fungal infection, but it has spread widely in recent times.

These mucous fungi mainly affect people with weak immune systems, and most often infect the sinuses and lungs. So if you would like to know more information about black fungus disease, what its symptoms are and how to treat it, follow this article with me.

What is black fungus disease?

Black fungus disease, known as zygomycosis, is a rare and serious fungal infection caused by a group of fungi, which are known as mucormycetes.

These fungi are usually found in the environment surrounding us, especially the following places: –

  1. Leaves.
  2. Organic fertilizer.
  3. Soil.
  4. Animal dung.
  5. Decomposed organic matter.

Infection occurs when these fungi enter the body through open wounds in the skin, or inhalation.

  • Skin.
  • Sinuses.
  • Lungs.
  • Stomach.
  • Intestines.
  • Brain.

People with diabetes, various types of cancer, or other medical conditions that weaken their immune system are more susceptible to black fungus disease.

It must be noted that this infection may be fatal if left untreated.

Causes of black fungus disease

Black fungus disease may result from inhaling fungus spores from the air, which leads to infections in the lungs, brain, or Sinuses.

The fungus can also enter the body through damaged skin as a result of the following: –

  1. Injuries.
  2. Surgical operations.
  3. Burns.
  4. Skin trauma.

Although these fungi are found naturally in the environment, not everyone who is exposed to them will develop this fungal infection.

  1. Diabetes, especially if it is irregular.
  2. Cancer.
  3. Organ transplantation.

  8. Metabolic acidosis.
  9. malnutrition.
  10. Premature birth.
