This study assessed human and domesticated non-ruminant interaction and the risks of parasitic zoonosis in the One-Health Concept in the Wa West District of Ghana. Using a descriptive cross-sectional design, 286 faecal samples were collected, 221 from non-ruminants and 65 humans. Using a structured questionnaire, participants were interviewed face-to-face, while faecal samples of animals and humans were collected and examined using concentration techniques. The majority and 26 and 34 years old. Most (69.0%) participants raised animals using an extensive system, and 50.0% did not routinely inspect or monitor their animals’ health. The prevalence of intestinal parasites among the non-ruminants and humans was 60.60% and 67.69%, respectively. Of all the faecal samples examined, 21 parasite species were recovered, of which 14 were isolated from humans. Ancylostoma caninum , Cryptosporidium sp., and Strongyloides sp., were the predominant parasites in the non-ruminants. In humans, Bunostomum sp. , Cryptosporidium sp. , Emeria sp. , Strongylus sp. , and Toxocara cati were the most prevalent parasites, each with a rate of 7.70%. Ancylostoma caninum, Toxocara canis, Toxocaris leonina, and Trichuris vulpis were recovered from dogs, their specific host. However, Cryptosporidium sp. , Ascaris sp. , Paragonimus kellicotti, and Strongyloides sp., whose specific host is man, were also recovered in non-ruminants. This study recorded a high prevalence of multiple parasitic infections with cross-transmission of species between non-ruminants and humans with zoonotic potential in the Wa West District. The cross-transmission of parasite species between host-specific non-ruminants and humans is linked to their close interaction and sharing of a limited space. The outcome of this study has dire implications for animal and human health and calls for implementing the One-Health Concept to curb the outbreak of parasitic zoonosis in this region.
Author Summary
Zoonotic parasitic infections pose a significant public health challenge, especially in rural communities where close contact with domestic animals is common. This study, conducted in the Wa West District of Ghana, applied a One Health approach to investigate the prevalence and types of intestinal parasites in humans and domesticated non-ruminant animals such as dogs, pigs, poultry, and cats. A total of 286 fecal samples (221 from animals and 65 from humans) were analyzed using concentration techniques, and 21 parasite species were identified, with notable overlap between those found in humans and animals. The study revealed high infection rates: 60.60% in animals and 67.69% in humans. Several parasites, including Cryptosporidium spp. and Strongyloides spp., were found in both hosts, indicating active cross-transmission. These findings emphasize the public health risks associated with poor animal husbandry practices, lack of routine veterinary care, and shared based One Health interventions that promote animal and human health simultaneously through coordinated surveillance, improved hygiene, and education in rural Ghana and similar settings.
