The domestic dog is the primary reservoir host as well as the most important source of infection usually conveyed by saliva through bites. Aim: This study sought to determine the frequency and outcome of dog bite injury and clinical rabies presented to the Accident and Emergency unit of Benue State University Teaching Hospital Makurdi, Benue State, Nigeria. Methods: This retrospective hospital-based study reviewed the medical records of all patients with dog bite who presented over an eight-year period from August 2014 to July 2022. Rabies virus infection was diagnosed on clinical basis. A structured proforma was used to extract relevant information and data was analysed using the statistical package for social sciences (SPSS) version 21. Result: Mean and median age was 27.03 ± 10.98 and 29 years respectively, range of 2 - 47 years and 11 (73.3%) were males. There were 15 cases of dog bite out of 17,187 patients making frequency of 1.14 per 1000 persons constituting 0.09% or about 2 cases yearly. Seven (46.7%) of this total number had clinical rabies infection with 7 (100.0%) mortality. All 7 (100.0%) with clinical rabies had a furious (encephalitic) form. Rabies immunoglobulin was prescribed in 8 (53.3%), 6 (40.0%) received them while 13 (86.7%) received post-exposure rabies vaccine. Conclusion: Dog bite is an uncommon reason for Accident and Emergency visit in our facility with male preponderance. However, about 46.7% of the dog bite victims developed clinical symptoms suggestive of furious (encephalitic) form of rabies with 100.0% fatality.展开更多

The Standardized Precipitation Index (SPI) 12 months’ time scale was computed from long-term rainfall data between 1960 and 2015 obtained from the Nigerian Meteorological Agency (NIMET) Abuja. The SPI results were further subjected to Mann-Kendal and Sen’s slope analysis for trend detection. To assess the vulnerability of drought and occurrence zones, the SPI and other geo-spatial techniques were employed to generate drought vulnerability maps for three epochs: 2000-2005, 2005-2010 and 2010-2015 respectively. The SPI values were interpolated using Inverse Weighted (IDW) techniques in ArcGIS10.5 to generate the vulnerability maps for the selected model years. The outcome of drought trend and vulnerability maps reveals increasing drought trend dominated by near normal and moderate conditions in Abuja, Ilorin and Lokoja while moderate and severe droughts were observed in Minna and Jos. The study therefore recommends holistic drought monitoring and management strategies in order to mitigate its adverse impact on water resources and rainfall-dependent agriculture.展开更多

This was done through the assessment of the status of water resources management in the region, evaluation of existing policy and strategy of water management, identification of the management problems and the prioritization with RIAM. The stakeholders identified water resources management problems, ranked them in other of severity in different categories and also evaluated them using the RIAM techniques in the administered questionnaire. Eleven problems were analyzed based on the physical/chemical, biological/ecological, social/cultural and economic/operational factors using several impact indicators. Scores were assigned, the RIAM models applied and the averages taken to arrive at the final assessment scores. The two major water resources management problems identified are: 1) inadequate funds for further agricultural, hydroelectric, navigation and industrial development;2) poor data collection and banking. These problems were prioritized by RIAM in order of severity for urgent intervention. The RIAM technique has made a key contribution to the prioritization of water resources management by providing insights into urgent problems according to stakeholders and thus guides the policy maker in appropriate decision making.展开更多

This study examines rainfall variability in the North Central region including the Federal Capital Territory Abuja using remote sensing and geographic information system (GIS) application. The study employed satellite data basically from near real time data of Moderate Resolution Imaging Spectroradiometer (MODIS). Thereafter, the point data of rainfall was clipped to the shape file of Nigeria Boundary and interpolation using Inverse Distance Weight (IDW) was done to generate rainfall spatial maps from 2000-2017. The result reveal high temporal variation in rainfall particularly Niger, Plateau, Benue and Nassarawa states. The study therefore recommends close monitoring of periodic pattern of rainfall characteristics in the region by the Nigerian meteorological agency and to encourage farmers into drought tolerant and irrigation farming.展开更多
