This study aims to report the number of animal cases identified in the central-south region of Paraná. It also seeks to correlate these findings with human diagnoses, thereby underscoring the importance of the One Health approach in implementing prophylactic measures and protocols for evaluating both positive and suspected cases. In August 2023, a cat diagnosed with sporotrichosis was presented at the UNICENTRO Veterinary School Clinic. Accompanying the cat was its guardian, who exhibited characteristic lesions of the disease. An epidemiological study was then initiated and spanned from August 2023 to March 2024. Cytological tests were performed on the suspected cases. From the epidemiological survey, 21 animals were tested. A total of 15 cats were confirmed to have sporotrichosis; all were unneutered males of the moggy breed with access to outdoor environments. Some pet owners also displayed symptoms and lesions consistent with sporotrichosis. Considering the recent surge in sporotrichosis cases in Brazil, along with its zoonotic potential and significance for public health—and considering its status as a notifiable disease—epidemiological studies such as this one are vital. They help in understanding the spread of the disease and are crucial for the development and implementation of prophylactic measures to protect human and animal health.
