Introduction: geographic distribution of dog bite victims is a critical input in assessing the spatial pattern of rabies exposures and formulating logical framework for more effective detection, surveillance and control of the disease at the dog-human interface.The dearth of data establishing the true epidemiological pattern of rabies distribution necessitates mapping of dog bite victims (DBVs) in a southwest state of Nigeria. We developed spatial model of DBVs and human rabies exposure in Ogun State, Nigeria.
Methods: victim’s residential site name generated from clinic records of human health facilities over a 5-year retrospective period (January 2013 to December 2017) and places of rabies exposure in the primary data were converted to map points using a standard procedure. A total of 303 DBVs presented for rabies exposure treatment in Ogun State were enlisted on ageospatial observation-linked data (RAB-GOLD) profile. Space-time cluster scan of DBVs was computed on space-time permutation model with significance set at 0.05.
Results: three space-time clusters of DBVs (1.04km radius in rural environment; geographic centre at 7.136072°N, 3.335114°E), (1.02km radius in urban environment; geographic centre at 7.172339°N, 3.371367°E) and (0.05km radius in rural environment; geographic centre at 6.832203°N, N, 3.631914°E), respectively were identified with rabies exposures.
Conclusion: preponderance of rabies exposure in urban compared to rural environment may indicate geographic disparity in care-seeking preferences among dog bite victims in Ogun State. This suggests potential under-reporting of victims to public health facilities. There is need for more effective rabies surveillance beyond major hospitals by including indigenous facilities.
