Is Black Fungus Harmful to Humans?
Black fungus is a rare but serious infection caused by a group of molds that you can usually find inside soil, plants, and rotting foods. If a healthy person brushes against these molds, it mostly does nothing at all, however, for a small group of people with weak immune systems, this same mold can become harmful. Fear around the fungus grew during the COVID-19 pandemic, when hospitals in some countries suddenly started flooding with black fungus cases. The news reports barely explained: Who is most at risk? How does it spread? And should you worry about it? In this blog, we’ll answer the top questions people have and see whether black fungus is harmful or not. The sections below cover what the infection is, how dangerous it really is, and what the early signs to watch for are. What is Black Fungus, Really? Black fungus is the common name for mucormycosis, an infection caused by molds known as mucormycetes. You can find these molds everywhere, from the soil to dead leaves, in compost heaps, and even the black spots that appear on spoiled bread or fruits. Most people breathe in tiny mold spores every day but never notice, because a healthy body clears them out easily. The word “black” comes from what the fungal infection does to living tissue. As the mold spreads, it blocks blood flow, and the starved tissue dies and turns dark. In advanced cases, it shows up as dead skin, black crusts inside the nose, or a blackened patch on the face. The mold itself is not truly black; the color comes from the damage it creates to the cells. How To Identify Black Fungus? Many people get confused with the name, because a lot of fungi and molds are referred to as black fungus. The first one is a type of edible mushroom, often called wood ear. It is also sold as black fungus and used in soups and stir-fries. This fungus is safe for most people to eat and has nothing to do with the infection we are talking about here. The second one is black mold, which you can find in damp houses. It is mostly linked to allergies and breathing problems rather than this harmful disease. The rest of this article is only about mucormycosis, also referred to as black fungus. So is Black Fungus Dangerous To Humans? Yes, black fungus can be very dangerous, but the risk is not spread evenly across people. For someone healthy, the odds of getting sick from these molds are very low. For someone whose immune system is weak, the infection can move quickly through the sinuses, lungs, or skin and reach the brain or the blood. The disease becomes serious once it becomes stronger. Studies by the United States Centers for Disease Control and Prevention report that nearly half of all reported cases die even with treatment. The sooner the black fungus infection is caught and treated, the better the chance of survival. If there are delays, the mold can reach hard-to-treat areas. So the honest answer is that black fungus is harmful and a real danger to a specific group of people and poses little to no threat to healthy ones. How Does a Person Catch Black Fungus? A person can catch black fungus from the following sources: Breathing in spores is the most common route, which is why the sinuses and lungs are often the first areas to get affected. Spores can settle into a cut, scrape, burn, or surgical wound on the skin. In some rare cases, swallowing contaminated food can cause the mold to reach the gut. Black fungus is a non-communicable disease and cannot pass from one person to another, so you cannot catch it from a cough, a handshake, or sharing a room with a patient. Who is Most at Risk of Getting Black Fungus? Black fungus targets people whose defenses are already down. A strong immune system treats the mold as a minor nuisance and clears it. People at risk of getting it include: Health Conditions Uncontrolled diabetes is one of the strongest indicators of a weak immune system, as this causes the blood sugar to run very high and the blood to turn acidic. Other conditions like cancer, organ or stem cell transplants, and HIV/AIDS also lower the body’s fighting response. This can make them at risk of catching the disease. If someone has too much iron in the body, this too can put them at risk, as the fungus can feed on the iron and grow. Medicines and Injuries That Open the Door Long-term use of steroids, which are taken to calm the immune system, can raise the risk. Medicines given after a transplant to stop the body from rejecting a new organ can also pose a risk. If someone has burns, deep wounds, and other skin damage, this can give the mold an open entry into the body. This is often how a case of black fungus on skin begins. The common cause across every group is a body that cannot fight back due to a compromised or weakened immune response. What Are the Warning Signs of Black Fungus? The symptoms of black fungus depend on where the mold settles inside the body. If you see any of the following signs, it is advised to get a checkup done to rule out anything serious. Signs in the Face, Nose, and Eyes The most common signs start from the sinus and move towards the eye and the brain. Some warning signs include swelling on one side of the face, a blocked or bleeding nose, black crusts inside the nose, headache, fever, and pain around the cheeks or eyes. If you suddenly experience blurred vision, a drooping eyelid, or one bulging eye, it can point to a spreading black fungus infection. Signs in the Lungs If the mold targets the lungs, the illness can look like a stubborn chest infection. The person can also experience fever,
