BACKGROUND: Accessibility of street food source to dogs in Enugu, the capital city of Enugu State, south-eastern Nigeria was examined in relation to spatial patterns of animal bite injuries in the city.
METHOD: Retrospective data on animal bite injuries were retrieved from records of selected hospitals in Enugu and its environs during the period 2005-2011. Victim's residence and street point where animal bite incidence occurred were geo-referenced. Street food sources, including garbage disposal points, meat markets, slaughter facilities and public vehicle terminals in the city were observed and geo-referenced. Thematic maps were designed usingArcGIS 10.1. Spatial scan statistics was used to identify cluster pattern of animal bite injuries and fatal rabies cases. Coefficient of area correspondence (Ca) in spatial cluster with selected variables was computed.
RESULTS: One hundred and thirty one cases of animal bite injury cases were retrieved with traceable addresses. These comprised cat bites (n = 1, 0.76%), goat bites (n = 1, 0.76%), monkey bites (n = 2, 1.5%) and dog bites (n = 127, 96.98%). Fatal outcomes (n = 4, 3.15%) were recorded. Males within the age group, 0-15 (46.5%) were at the highest risk. A diffused spatial pattern showed that majority of the study area experienced animal bite injury during the study period. A primary cluster of 15.03km radius and a secondary cluster of 1.11 km radius traversed residential and non-residential areas were identified as rabies high- and low-risk areas. Interspecies bites from non-carnivores (goats and monkeys) and resultant deaths with neurologic signs were pathognomonic for rabies-like-illness in Enugu State. High Ca (0.8) showed a strong correlation between access to street food sources for dogs and the distribution of animal bite injuries on humans.
CONCLUSION: While access to street food may support the population of free-roaming dogs, it was also shown to be partly explanatory to spatial patterns of dog bite injury. Public education about responsible pet ownership, waste management, enforcement of animal control regulations and vaccination of free-roaming dogs is critical.
