Seroprevalence of Q fever (Coxiella burnetii) in sheep in the Kwahu West municipality, Eastern Region, Ghana

Query fever, also known as Q fever, is a zoonotic disease caused by Coxiella burnetii. It is a cause of abortion in livestock and presents as a febrile illness in humans. A correlation between the incidence of the disease in humans and abortion in goats and sheep farms has been reported in countries such as the Netherlands and Australia. In Ghana, the occurrence of Q fever in both livestock and humans has not been fully explored. This study sought to determine the seroprevalence of Q fever in livestock in Nkawkaw, in the Eastern Region of Ghana. Sera obtained from 92 sheep from 12 farms were tested using the indirect multi-species ELISA for the detection of anti-Coxiella burnetii antibodies. Animal demographics, farms’ proximity to human settlement and history of abortion in relation to the Q fever status were assessed. The overall prevalence of Q fever was 13.0 % [95 % CI 6.9–21.6] (12/92). Both sexes were equally affected, with a sex-specific prevalence of 13.0 % each. The farm-specific prevalence was 50 %. Abortions were reported on eight (8) of the 12 farms, and all farms were located less than 200 m from human habitation. Only proximity of farm to human settlement showed statistical significance. Q fever is prevalent in Nkawkaw and requires the attention of both animal and health authorities, using the One- Health approach to nip any future epidemics in its bud.
