Methods: A retrospective, record-based study was conducted in 200 animal bite victims presenting to district hospital Alwar, Rajasthan wherein information on monthly number of animal bite cases was collected from records section of the hospital. Information on annual number of animal bite cases was available from the annual report of the hospital from 2018 onwards, this data was used for studying the monthly variation in animal bite cases. Data were compiled and analyzed using Microsoft Excel. Results: Among 200 victims 76.3% were males, 56.7% belongs to 15-45 years, 61.6% were living in urban area, 31.3% and 21.7% of the victims were agriculture worker and laborers respectively. Among 95.8% victims bitten by dog, 89% of them were stray. 89.4% had category III bite, lower extremity affected in 60.8%, fate of animal was unknown in 78.6% and 46% of the victims were bitten during evening hours. Conclusions: Majority of bites were by stray dogs, unprovoked and category III bites.

There is a need to control stray dog population and immunize pet dogs.
