Background and Objective: The incidence rate of animal bite in Quchan city is much higher than national and provincial average. This project was done to study the epidemiologic distribution of animal bite cases in Quchan city. Materials and Methods: In this cross sectional study, all animal bite cases of Quchan city in 1392 were studied. Then collected data was entered SPSS17 software and were analyzed by few tests such as t-test, chi-square, and logistic regression. Results: Most cases were 21-30 years old and mean of age was 32.2±19.8 years. 31.3% were female and 68.7% were male. The risk of severe injury by stray animals was 2.5 times higher than pets and by dogs was 12.6 times higher than cats (P<0.05). Severity of injury in women were greater than men and women were about 10 years older than men in average (P<0.05). 16.3% of cases were city residents and 83.7% of them were rural residents. Highest number of cases of animal bite injuries occurred in June (11.2%) and the lowest in January (5.7%). The culprit animals in most case of bite injuries were dogs (86.7%) followed by cats (9.5%). Invasive animals in 95.2% cases were pets and domesticated and in 41.3% of them attacked their owners. 36.9% of cases were injured when they passed by the animal and 11.1% of them were injured when they entered the animal owner’s house. Most animal attacks occurred at 12-18 o’clock. Conclusion: Because incidence rate of animal bites in Quchan city is high, it is essential that provide an appropriate intervention programs to prevent and reduce the incidence of animal bites, especially in the rural young men and students and with emphasis on immunization the pets. سابقه و هدف: ميزان بروز حيوان گزيدگي در شهرستان قوچان از متوسط کشوري و استاني بالاتر است. اين مطالعه باهدف بررسي اپيدميولوژيکي موارد حيوان گزيده قوچان اجرا گرديد.روش بررسي: در اين مطالعه مقطعي، افراد حيوان گزيده شهرستان قوچان در سال 1392 بررسي گرديدند. داده ها پس از گردآوري، توسط نرمافزار SPSS17 و آزمونهايي مانند تي تست، کاي اسکوئر، رگرسيون لجستيک تجزيهوتحليل گرديد.يافتهها: ميانگين سني افراد حيوان گزيده 8/19±2/32 بود. 3/31% مؤنث و 7/68% مذکر بودند. احتمال ايجاد جراحت عميق توسط حيوانات ولگرد 5/2 برابر حيوانات اهلي و توسط سگ 6/12 برابر گربه بود (05/0>P). جراحت ايجادشده در خانمها شديدتر از آقايان بوده و ميانگين سني زنان حدود 10 سال بيشتر از مردان بود (05/0>P). 3/16% ساکن شهر و 7/83% روستايي بودهاند. بيشترين موارد در خرداد (2/11%) و کمترين موارد در ديماه (7/5%) بود (05/0>P). اغلب، جراحت توسط سگ (7/86%) و گربه (5/9%) ايجادشده بود. در 2/95% موارد، حيوان مهاجم، اهلي و صاحب دار بوده که در 3/41% موارد به صاحب خود حمله کرده بود. 9/36% افراد هنگام عبور از کنار حيوان، 1/18% موارد نامشخص و 1/11% هنگام ورود به منزل صاحب حيوان، مجروح شده بودند. بيشترين موارد حمله حيوان، ساعت 18-12 (مد ساعت 17) رخداده بود.نتيجهگيري: با توجه به بالا بودن ميزان بروز حيوان گزيدگي در شهرستان قوچان، تدارک برنامههاي مداخلهاي مناسب جهت پيشگيري و کاهش موارد حيوان گزيدگي به ويژه در مردان جوان روستايي و دانشآموزان و تأکيد بر ايمنسازي سگهاي صاحب دار ضروري به نظر ميرسد
