According to the World Health Organization (WHO), there are 4.5-5.4 million snakebites each year, and 1.8-2.7 million people develop symptomatic poisoning. Complications lead to the death of 81,000-138,000 patients annually and result in limb amputations or permanent disability in approximately 400,000 patients. This study aims to underscore the importance of early diagnosis and treatment for patients bitten by Vipera berus, as well as the need for education regarding the management of such cases. The paper presents the case of a 64-year-old female patient without comorbidities who was admitted to the Department of Infectious Diseases and Neuroinfections due to a Vipera berus bite. A physical examination revealed severe bruising and swelling of the right upper limb, as well as numerous hemorrhages covering the right half of the chest. In the following days, increasing swelling and spreading of the bruises were observed. Laboratory results showed anemia resulting from hemolysis of blood components. Over time, the bruising was gradually absorbed, and the swelling of the limb decreased. This case highlights the importance of prompt diagnosis and monitoring of local symptoms and coagulation parameters, rapid antitoxin administration, close observation of patients due to the risk of later deterioration, and education on management and differential diagnosis.
