- Answer:
- Mucormycosis is a fungal infection that causes blackening or discolouration over the nose, blurred or double vision, chest pain, breathing difficulties and coughing blood. Mucormycosis is caused by exposure to mucor mould, which is commonly found in soil, air and even in the nose and mucus of humans.
- It is caused by exposure to mucor mould which is commonly found in soil, plants, manure, and decaying fruits and vegetables. "It is ubiquitous and found in soil and air and even in the nose and mucus of healthy people," says Dr Akshay Nair, a Mumbai-based eye surgeon.
1.COVID-19-associated mucormycosis, commonly referred to as black fungus, is the association of mucormycosis with COVID-19. It has been reported around the nose, eyes and brain – a clinical manifestation sometimes referred to as 'rhino-orbital-cerebral mucormycosis'.
Several thousand coronavirus patients in India have contracted a deadly and aggressive fungal infection, compounding the country's woes as it reels from the pandemic.
Mucormycosis, dubbed "black fungus", is caused by a mould found in soil and in decaying organic matter like rotting leaves, according to the US Centers for Disease Control and Prevention (CDC).
People get mucormycosis, of which there are several types, by breathing in the fungal spores. They can be spread in hospitals and homes by air humidifiers or oxygen tanks containing dirty water.
The infection needs to be caught early as it is aggressive and dead tissue has to be scraped away. Surgeons sometimes have to remove patients' nose, eyes or even their jaw to stop it getting to the brain.
The average fatality rate is 54 percent, according to the CDC.
Once infected, people can die within days. However it is not contagious, according to the CDC. India normally deals with a few dozen cases a year.
Generally the body's defences repel the fungus and only those with severely weakened immune systems -- for example organ transplant or cancer patients -- are affected.
2.The normally rare infection, called mucormycosis, has a mortality rate of 50%, with some only saved by removing an eye or jaw bone.
But in recent months, India saw thousands of cases affecting recovered and recovering Covid-19 patients.
Doctors suspect there may be a link with the steroids used to treat Covid.
Generally, some types of fungi don’t cause any infections in humans but can cause sickness in people with weakened immune systems known as opportunistic infections.
Some common types of a fungal infection include:
*Skin infections like ringworm
*Nail infections
*Deeper cutaneous infections following trauma,
*Breach in the skin with subsequent fungal implantation and growth
*Sinus infections and deep lung infections
*The fungi can also affect the gastrointestinal system, renal systems and can cause a full-blown infection resulting from the entry of fungus into the bloodstream.
