Epidemiology of urban dog-related injuries requiring rabies post-exposure prophylaxis in Marseille, France

摘要

Background: Dog bites are a serious public health concern. Besides injuries and the adverse psychological impacts, dog bites can be complicated by infections including rabies, which has the highest case-fatality rate of all infectious diseases. Methods: Dog-associated injuries occurring in the city of Marseille, France were investigated in 245 individuals among patients presenting to the rabies treatment center over a 4-year period. Results: Male patients were more likely to report dog bites compared to female patients (66.5% vs. 33.5%; odds ratio 2.25, 95% confidence interval 1.72-2.93). The mean age of injured patients was 32 years (range 1-85 years). Children and young adults under 30 years of age were more than four times more likely to report dog bites compared to others. Most cases occurred outdoors (73.0%) - in public areas (38.0%) - and involved animals of unknown owners in 56.3% of the cases. Only 28.2% of dogs were available for observation. Most patients (63.7%) received complete rabies post-exposure prophylaxis. The distribution of dog bites in the city was not homogeneous and the incidence of bites was significantly higher in some areas. Eleven percent of patients declared having been bitten by dogs whose owner was a street beggar, and a clustered distribution was evidenced for these cases in one area of the city. Conclusions: Programs offering low-cost rabies vaccination and veterinary care to pets belonging to the group of street beggars should be considered. Such programs may be implemented in other large cities in France and Europe where street beggars are frequently seen.
