Objective: Scorpion is one of the world’s most venomous arthropods and every year many people are bitten by it. In Iran, scorpion sting is a common health issue. The aim of this study was to evaluate the epidemiological and clinical status of patients with scorpion sting in the emergency department of Sina hospital in 2014.

Methods: In this descriptive cross-sectional study, all patients with a history of scorpion sting during 2014 in the emergency department of Sina hospital in Tabriz entered the study. Required information such as sex, age, location and time of the sting, the patient’s symptoms, etc were extracted from the medical records. These findings were analyzed using SPSS version 15.

Of 176 patients, 83% lived in urban areas, 87% of scorpion sting cases occurred in houses, and 81.3% of stings were done by yellow scorpion. Most of the bites were in upper extremities (47.2%). In evaluation of symptoms and signs of patients, 89.8% had pain, 48.8% had local erythema and redness, 21% had inflation of sting position and 0.6% had pulmonary symptoms.
