 Sporotrocosis is a fungal skin infection caused by the sporothric skanky complex, which includes four species, S. brasiliensis, S. intermedia, S. Louisiana and S. shabarcovy. The late 1990s saw a shift from the traditional route of transmission, from cats to humans, to a new route involving humans to humans. This led to increased incidence rates among children and the elderly, as well as the emergence of more severe forms of the disease. Additionally, the use of molecular tools allowed researchers to identify and classify different species of sporothrics, some of which are more virulent than others. These advances have helped researchers better understand the epidemiology of sporotrocosis and develop effective treatments.
