<unk>  is a fungal infection caused by fungi in the order Mucorales. In most cases it is due to an invasion of the genera Rhizopus and Mucor, common bread molds. Most fatal infections are caused by Rhizopus oryzae. It is less likely due to Lichtheimia, and rarely due to Apophysomyces. Others include Cunninghamella, Mortierella, and Saksenaea. The fungal spores are in the environment, can be found on for instance moldy bread and fruit and are breathed in frequently, but cause disease only in some people. In addition to being breathed in to be deposited in the nose, sinuses and lungs, the spores can also enter the skin via blood or directly through a cut or open wound, or grow in the intestine if eaten. Once deposited, the fungus grows branch-like filaments which invade blood vessels, causing clots to form and surrounding tissues to die. Other reported causes include contaminated wound dressings.<unk>  has been reported following the use of elastoplast and the use of tongue depressors for holding in place intravenous catheters, Outbreaks have also been linked to hospital bed sheets, negative-pressure rooms, water leaks, poor ventilation, contaminated medical equipment, and building works. Risk factors Predisposing factors for<unk>  include conditions where people are less able to fight infection, have a low neutrophil count or metabolic acidosis. Risk factors include poorly controlled diabetes mellitus (particularly DKA), organ transplant, iron overload, cancers such as lymphomas, kidney failure, long term corticosteroid and immunosuppressive therapy, liver disease and severe malnutrition. Other risk factors include tuberculosis (TB), deferoxamine and to a lesser extent HIV/AIDS. Cases of<unk>  in fit and healthy people are rare. Corticosteroids are commonly used in the treatment of COVID-19 and reduce damage caused by the body's own immune system during a coronavirus infection. They are immunosuppressant and increase blood sugar levels in both diabetics and non-diabetic patients. It is thought that both these effects may contribute to cases of<unk> .
