Abstract

Introduction: Dog bites in humans are a major public health problem. Globally, millions of people are bitten by dogs but most of the fatal cases occur in children. Dog bites in human are a serious public health problem and have been well documented worldwide. As rabies is not a notifiable disease in Bangladesh and most deaths occur in rural areas where surveillance is poor. Objectives: To determine the pattern of dog bite injuries and associated health problems among children. Methods: The study was an observational retrospective study carried out at the Dept. of General Surgery, Chuadanga Sadar Hospital, Chuadanga, Bangladesh. The study reviewed the clinical data of patients managed for dog bite related injuries and rabies over a four and half year period between January 2016 and June 2020. A proforma was designed to extract relevant clinical data from the case records. Information extracted included the age, sex of the victims, site of the bite, time of presentation in the hospital, pre-hospital treatment, hospital treatment including post-exposure prophylaxis and complication. Results: In all, 200 cases of dog bite injuries were managed constituting 0.89% of the total consultations; 5 (2.5%) had rabies. Most of the victims were aged 6-12 years (55.0%) and majority (67.0%) was boys. Eighty two percent of the victims presented within 24hrs of the injury. 92 (46.0%) had WHO grade 3 dog bite injury at presentation and the lower limb was the commonest (56.0%) bite site. Use of herbal preparation was the most common pre-hospital treatment 60%. Although 95.0% received anti-rabies vaccine, only 55.5% of them completed the vaccination schedule. The case fatality rate for dog bite was 5.0%. The 5 that died all presented late, had no post exposure prophylaxis and died within 24 hours of admission. Conclusion: There is need for public enlightenment on dangers associated with dog bites and also for the government to ensure vaccination for cost of post exposure prophylaxis treatment for children free of cost
