Differential diagnosis
Some tinea and candidiasis infections of the skin can appear similar to eczema and lichen planus. Pityriasis versicolor can look like seborrheic dermatitis, pityriasis rosea, pityriasis alba and vitiligo.Some fungal infections such as coccidioidomycosis, histoplasmosis, and blastomycosis can present with fever, cough, and shortness of breath, thereby resembling COVID-19. Prevention
Keeping the skin clean and dry, as well as maintaining good hygiene, will help larger topical mycoses. Because some fungal infections are contagious, it is important to wash hands after touching other people or animals. Sports clothing should also be washed after use. Treatment
Treatment depends on the type of fungal infection, and usually requires topical or systemic antifungal medicines. Pneumocystosis does not respond to anti-fungals is treated with co-trimoxazole. Sometimes, infected tissue needs to be surgically cut away. Epidemiology
Worldwide, every year fungal infections affect more than one billion people. An estimated 1.6 million deaths from fungal disease were reported in 2017. The figure has been rising, with an estimated 1.7 million deaths from fungal disease reported in 2020. Fungal infections also constitute a significant cause of illness and mortality in children.According to the Global Action Fund for Fungal Infections, every year there are over 10 million cases of fungal asthma, around 3 million cases of long-term aspergillosis of lungs, 1 million cases of blindness due to fungal keratitis, more than 200,000 cases of meningitis due to cryptococcus, 700,000 cases of invasive candidiasis, 500,000 cases of pneumocystosis of lungs, 250,000 cases of invasive aspergillosis, and 100,000 cases of histoplasmosis.
The yeast Candida albicans can live in people without producing symptoms, and is able to cause both superficial mild candidiasis in healthy people, such as oral thrush or vaginal yeast infection, and severe systemic candidiasis in those who cannot fight infection themselves.Diagnosis is generally based on signs and symptoms, microscopy, culture, sometimes requiring a biopsy and the aid of medical imaging. Some superficial fungal infections of the skin can appear similar to other skin conditions such as eczema and lichen planus. Treatment is generally performed using antifungal medicines, usually in the form of a cream or by mouth or injection, depending on the specific infection and its extent. Some require surgically cutting out infected tissue.Fungal infections have a world-wide distribution and are common, affecting more than one billion people every year. An estimated 1.7 million deaths from fungal disease were reported in 2020. Several, including sporotrichosis, chromoblastomycosis and mycetoma are neglected.A wide range of fungal infections occur in other animals, and some can be transmitted from animals to people. Classification
Mycoses are traditionally divided into superficial, subcutaneous, or systemic, where infection is deep, more widespread and involving internal body organs. They can affect the nails, vagina, skin and mouth. Some types such as blastomycosis, cryptococcus, coccidioidomycosis and histoplasmosis, affect people who live or visit certain parts of the world. Others such as aspergillosis, pneumocystis pneumonia, candidiasis, mucormycosis and talaromycosis, tend to affect people who are unable to fight infection themselves. Mycoses might not always conform strictly to the three divisions of superficial, subcutaneous and systemic.
