Fungal dermal diseases caused by the molds of the Dermatophyte family are among the most frequent infectious diseases affecting quality of life. There are 3 attributed sources of infection by Dermatophytes:1) humans; 2) animals and 3) soil. Dermatophytes posses the ability to utilize keratin from human and animal tissues, or debris from dead animal sources found in soil, such as feathers, skin or nails. Hence, Dermatophytes are abundant in different ecological niches. All 3 groups can infect humans, causing dermatophytoses manifested in different clinical entities involving skin, hair or nails. The mode of infection of the Dermatophytes is via direct or indirect contact. Dermatophytes are found universally, however the relative prevalence of dermatophytoses caused by different Dermatophytes may vary in different geographic areas according to climatic conditions or lifestyle.Thus, studies in different geographic areas assessing the specific fungal etiology involved are of epidemiological relevance serving as baseline information for management of dermatophytoses at the local level.The present article will focus, mostly, on epidemiological data from published surveys conducted in different geographic/climatic areas analyzing the prevalence of specific Dermatophyte species in regard to gender, age, type of infection in context of environmental factors.
