Characterization and treatment protocol of injuries inflicted to humans by synurbic European wild boars (Sus scrofa)

Wild boar (Sus scrofa) has spread and colonized urban areas. The closer contact with humans can lead to wild boar-inflicted injuries. The objectives of this study are: 1) to systematically review the literature on wild boar-inflicted injuries; 2) to describe our wild boar-inflicted wound management protocol; and 3) to analyse the features, outcomes and complications of our case series.

First, a systematic search of the literature was performed using the PubMed (MEDLINE) electronic database. Then, our evidence-based wild boar-inflicted wound management protocol was described. Finally, a retrospective case series study including all the patients with wild boar-inflicted injuries attended in our Emergency Department (2020-2022) was analysed.

Fourteen studies (twelve case reports and two case series) were selected for the literature review. Our case series included 34 patients: 50.0% of them presented superficial wounds and 38.2% penetrating wounds. Most of the wounds occurred in the lower limbs (71.9%). Following our protocol, 30.0% of the wounds were primarily closed, the 70.0% of the patients received antibiotics (92.3% in penetrating injuries) and the 26.7% received an antitetanic vaccine. Only one patient (2.9%) presented a complication.

This study reports the first specific wild boar inflicted-wound management protocol, which led to a low complication rate. Open wounds affecting the lower limbs were the most common lesions. Care should be taken with penetrating tusk injuries. Wide-spectrum antibiotic and antitetanic treatments are recommended. Decisions on wound management should be taken case-by-case, while antirabies vaccination depends on the local status of the disease.
