Abstract
INTRODUCTION: This study aimed to describe the profile of freshwater stingray injuries in the State of Amazonas, Brazilian Amazon, and to identify the associated risk factors for secondary infections. METHODS: This cross-sectional study used surveillance data from 2007 to 2014 to identify factors associated with secondary infections from stingray injuries. RESULTS: A total of 476 freshwater stingray injuries were recorded, with an incidence rate of 1.7 cases/100,000 person/year. The majority of injuries were reported from rural areas (73.8%) and 26.1% were related to work activities. A total of 74.5% of patients received medical assistance within the first 3 hours of injury. Secondary infections and necrosis were observed in 8.9% and 3.8%, respectively. Work-related injuries [odds ratio (OR) 4.1, confidence interval (CI); 1.87-9.13] and >24 hours from a sting until receiving medical care (OR; 15.5, CI; 6.77-35.40) were independently associated with the risk of secondary bacterial infection. CONCLUSIONS: In this study, work-related injuries and >24 hours from being stung until receiving medical care were independently and significantly associated with the risk of secondary infection. The frequency of infection following sting injuries was 9%. The major factor associated with the risk of secondary bacterial infection was a time period of >24 hours from being stung until receiving medical care.
