Dog population structure in Kumasi, Ghana: a missing link towards rabies control

Abstract

Introduction: dog-mediated human rabies remains a major public health threat in Ghana. Dog population structure surveys are pre-requisites for
appropriate planning for rabies vaccination; however, this information is unavailable in Ghana. This study describes dog population structure in
Kumasi, Ghana. Methods: a household cross sectional survey was conducted from January through April 2016 in Ayeduase and Kwame Nkrumah
University of Science and Technology (KNUST) campus using a structured questionnaire. Results: a total of 1319 households were surveyed out of
which 35.1% (463/1319) kept dogs. We recorded 816 dogs from 463 households, giving dog to household ratio of 1.8:1. Respondents acquired 71%
(579/816) of dogs through purchase. Of 2065 persons in Ayeduase, 406 owned dogs, resulting in man to dog ratio of 5.1:1. Male dogs represented
62.9% (513/816) while those aged a year and above recorded 70%. Most of the dogs were not restricted (80.3%) and 49.9% were allowed to enter
neighbors' households. Dog rabies vaccination coverage was 28.1% and 64.9% in Ayeduase and KNUST campus respectively. Respondents (87.8%)
from Ayeduase knew dog bite was the main means of rabies transmission, however, about 65% believed in traditional ways of treatment such as
concoction, herbs and consumption of offending dogs' organs. Conclusion: the high dog to household-human ratio, increased roaming dog
population and low vaccination coverage is of concern to rabies. Respondents' knowledge on their dogs is an indication of accessibility for vaccination.
Obtained results can be useful for rabies vaccination planning in Kumasi and other comparable settings in Ghana.
