Mycosis, often known as a fungal infection, is a condition brought on by a fungus (yeast or mould). Although fungi (plural of fungus) can cause infections in your mouth, throat, lungs, urinary tract, and many other parts of your body, fungus infections are most frequently found on your skin or nails.

Living organisms that are not considered to be part of either plants or animals are fungi. They disperse or release spores (reproductive components) into the environment to migrate about. Numerous fungi naturally exist in our bodies (mouth, GI tract, skin), but they have the potential to overgrow. Although there are reportedly millions of fungi in the world, only a small fraction of them are known to be harmful to humans. This also applies to specific yeasts and moulds.
Skin infections appear as rough,red and puffy. You might be able to see a lump under your skin or they may resemble a rash. Your nails may get discolored due to a fungus infection.
A fungal infection can affect anyone, especially if it affects your skin or nails. On your body, areas with high friction or moisture retention are more prone to fungus infections. If you have diabetes, poor circulation, poor immune function, or any of the following conditions, you are more susceptible to infection, especially serious infections:
The most typical fungal infections, such as those that affect your skin or nails, are typically not dangerous. You run a higher chance of developing a serious illness from specific fungal infections if your immune system is compromised.
A fungus can infect your skin, nails, or mucous membranes on the outside of your body (superficial or mucocutaneous infections), beneath your skin (subcutaneous infections), or inside other organs like your heart, lungs, or brain (deep infections).
Your nails, skin, and mucous membranes (such as those in your mouth, throat, or vagina) can become infected with superficial fungi.
You may get a fungal infection (subcutaneous infection) if fungus penetrates a cut or wound, typically as a result of an injury experienced while working with plants (such as a scratch from a thorn). They cause rashes, ulcers, and other symptoms on the skin. These infections are more common in tropical and subtropical areas of the world. Examples include:
Deep fungal infections can also affect organs other than your skin, such as your lungs, blood, urinary system, or brain. Because some infections are opportunistic, they typically only cause illness in people with already weakened immune systems.
Deep or invasive fungal infections include:

The type of fungal infection you have and where on your body it is located will determine your symptoms. The skin, nails, or mucous membranes (such as the mouth, throat, or vagina) are where symptoms are most frequently found. You may occasionally experience signs of an infection in your sinuses, brain, eyes, intestines, or lungs.
The following are some signs of superficial or subcutaneous infections:
In the affected area, there may be rash, itching, or soreness.
cracked, thick, or discolored nails.
White patches in the tongue or throat, taste loss, or discomfort during eating.
A smooth, under-the-skin bump.
Fungal infections of lungs gives following symptoms:
Yeast, mould, and other fungi can cause fungus infections. Only a small percentage of fungi can make people sick by infecting them. Some infections are opportunistic, which means they frequently do not cause infections but can take advantage of particular situations, like an immune system that is weak.Several common fungi can cause infections in people, including:
Dermatophytes. The outer layer of skin, nails, and hair are all made of keratin, which is the food source for a group of fungi called dermatophytes. They do not infect living tissue.
Candida. Your body naturally contains Candida albicans, a yeast that rarely causes problems. Under certain conditions, it might expand excessively, which can cause redness and irritation. Sometimes, it can lead to life-threatening infections.
Environmental fungus that dwell in water or soil. Examples include Histoplasma, Coccidioides, Blastomyces, and Aspergillus.
Typical methods of acquiring fungi infections include:
The location of the fungal disease on your body affects how your doctor identifies it. It's possible that they'll try to develop (culture) fungus using samples of your:
Antifungal medication, which kills fungus on and in your body, can treat many fungal illnesses. Depending on where the fungus is, your doctor may prescribe a variety of drugs.
Before treating a fungal infection, it's a good idea to consult with your provider. Some medicines may be available over-the-counter (OTC). Your healthcare practitioner could provide an antifungal medication in the following forms to treat a fungal disease:
Practise proper personal hygiene and shield yourself from environmental fungus as ways to lower your chance of contracting certain fungal illnesses. To prevent fungal infections, consider the following:
Whether you have underlying conditions and the location of the infection on your body will determine what to anticipate when you have a fungal infection. Hair, skin, and nail fungus infections are often not dangerous, although therapy may take some time to fully resolve. Deep fungal infections, such as those in the lungs or other organs, can be fatal, especially if your immune system is already compromised.
