Sporotrichosis is a mycotic disease caused by Sporothrix spp., whose zoonotic transmission by sick cats is the main infection route in Brazil. The aim of the current study is to report a human sporotrichosis outbreak caused by zoonotic transmission from a feline, with emphasis on the importance of making differential diagnosis and of using personal protective equipment. A hospital team member presented injury in the arm after having handled a cat that had been hospitalized for being hit by a car. The animal presented skin lacerations, myiasis, and full tibial fracture - there were no other signs of skin lesions. Clinical samples were collected from both the human and the suspected cat, for mycological culture; results have shown Sporothrix sp. growth. A search was conducted to identify other hospital team members who also had contact with the animal. Other six individuals also had suspected lesions in their arms, hands and ocular area; they were all subjected to sample collection. Mycological results have also confirmed Sporothrix spp.; sequencing analysis has shown that all seven humans were infected with Sporothrix brasiliensis. Since Southern Brazil is endemic of this disease, it is worth emphasizing the importance of taking into consideration zoonotic risks at the time to provide emergency care to stray animals, mainly felines, as well as of using Personal Protective Equipment while handling them - regardless of whether they present, or not, typical clinical symptoms or history of the disease, given the potential zoonotic risk posed by Sporothrix brasiliensis.
