Background Rabies is a zoonotic viral disease that can occur in all warm-blooded animals, including humans. Vaccinating dogs can protect people from contracting rabies. Rabies is a public health threat in Rwanda, but the country does not have information on the epidemiology of rabies. The present study aimed to understand the knowledge, attitudes and practices (KAP) of rabies and its control among dog owners in Kigali city of Rwanda. Methods We conducted a cross-sectional survey using a structured questionnaire among 137 dog owners selected from nine administrative study sites. A two-stage random sampling procedure was used to select the participants. Frequency distributions analysis and a series of chi-square tests of associations as well as binary logistic regressions were performed to determine the important factors associated with the response variables. Results The results showed that 99.5% of respondents knew at least a host susceptible to rabies. Only 22.4% and 21.3% knew that dogs and people can develop rabies, respectively. Nearly 73.6% knew that human rabies can be transmitted through dog-bites and 99% could identify at least a clinical sign of canine rabies. Overall, 81.8% knew that regular vaccination of dogs helps to prevent dog-transmitted human rabies and 43.1% and 26.3% were aware that rabies in humans and in dogs are fatal once clinical symptoms have shown, respectively. Only 69% would observe a dog for 10 days after it bites a man or an animal. Approximately 20.4% were familiar with appropriate cleaning of dog-bites wounds, and 20.6% knew that puppies could receive rabies vaccination before they are three months old. Of those who owned vaccinated dogs, 78% were happy about the cost (US $ ≤ 34) of rabies vaccination. Of all the respondents, 58% had their dogs vaccinated at home by veterinarians while 86% indicated their veterinarians kept rabies vaccines on ice in a cool box. Overall, 53% of the dog owners had sufficient knowledge of rabies, whilst 66% and 17% adopted adequate practices and positive attitudes towards rabies, respectively. Multivariable logistic regression analyses indicated that none of the respondents’ sex, educational level, and the length of dog ownership were statistically associated with their knowledge, attitudes and practices of rabies. Conclusions This study showed that majority of the dog owners had sufficient knowledge and adopted appropriate practices of rabies. However there exist some knowledge gaps among the dog owners particularly on treatment, transmission and control methods. Therefore, rabies awareness campaign is required to upgrade rabies knowledge of the dog owners on rabies prevention and control in Rwanda.

Background: Rabies is a zoonotic viral disease that can occur in all warm-blooded mammals, including man [1]. Vaccinating dogs can protect people from contracting rabies [2]. Annual deaths due to rabies was estimated to 61000 worldwide [1], and Africa represented 35.2% of the deaths [3]. In Rwanda, rabies is a public health threat to the public [4], but the country does not have information on the disease [5]. Methodology: The present study aimed to assess knowledge, attitudes and practices (KAP) of rabies and its control among dog owners in Kigali city, Rwanda. We conducted a cross-sectional survey using a structured questionnaire among 137 dog owners randomly selected within each of the selected 9 study sites. A series of chi-square tests of association and binary logistic regression were used to determine the important factors associated with the response variables. Results: The results showed that 99.5% of respondents could mention at least a host susceptible to rabies. Only 22.4 % and 21.3 % knew about canine and human rabies, respectively. Nearly 73.6% knew that human rabies can be transmitted through dog-bites and 99% could identify at least a clinical sign of canine rabies. Nealy 81.8% thought that regularly vaccinating dogs could prevent people from contracting dog-transmitted rabies. Only 43.1% and 26.3% were aware that clinical human and canine rabies are always deadly, respectively. Respondents who would observe a dog for some time, once it bites a man or an animal, represented 69%. Only 20.4% were familiar with cleaning dog-bites wounds with water and soap, before attending health care facilities. Few respondents owning dogs (20.6%) knew that puppies could receive rabies vaccination before the age of three months. Of respondents who owned vaccinated dogs, 78% were happy about the cost of rabies vaccination of dogs (Rwandan Francs 0-30,000). Nearly 57.9% had their dogs vaccinated at home by veterinarians. Eighty-two (82%) percent of respondents received rabies information from neighbours, the media and public meetings. Logistic regression analyses indicated that none of respondents’sex, education level, and duration of dog ownership was statistically associated with their knowledge of rabies. The respondents who had kept dogs for 5-10 years were less likely to have as sufficient knowledge as those who had kept dogs for more than ten years (AOR=0.96). Male respondents were more likely to adopt a positive attitude (AOR=1.47) and have appropriate practice (AOR=1.40) towards rabies. The respondents who had completed at least primary education, were more likely to have appropriate practice of rabies (AOR=1.41). Conclusions: This study identified gaps in the dog owners’ rabies knowledge of transmission, treatment and control. In addition, none of respondents’sex, educational level, and dog ownership length was statistically associated with their rabies knowledge. Overall, this study indicated that all categories of dog owners in Kigali city did not have good levels of rabies knowledge. Rabies interventions including awareness component in the studied population should be homogeneously improved.

Canine nematodes pose a public health risk to humans and livestock; however, the prevalence of canine nematodiases in Rwanda is unknown. This study aimed at determining the prevalence of canine nematodiases and identifying the risk factors for such infections in Kigali, the capital city of Rwanda. A cross-sectional study involved 93 dogs selected across Kigali city. Faecal samples were collected from apparently healthy dogs, and nematode eggs were identified and quantified using the McMaster technique. Risk factors for canine nematodiases were analysed by a multivariable binary logistic regression model. The overall prevalence of gastrointestinal (GI) nematodiases in dogs was 33.3% (95% CI: 23.8–42.9). The most prevalent species was Ancylostoma spp with 32.3% (95% CI: 22.8–41.8). Nearly 38.7% and 3.2% of the dogs infected with Ancylostoma spp and Toxocara canis had high egg counts per gram (EPG) of faeces (≥550), respectively. Approximately 96.8% of dogs infected with nematodes had monoinfection. Logistic regression analysis showed that dog’s age (1 to 2.5 years old), location (Gasabo and Kicukiro districts), and feeding practices were significantly associated with prevalence of canine nematodiases. In particular, the adjusted odds ratio (AOR) was more than 5 times higher for dogs fed on uncooked animal products and leftovers from households and restaurants compared to those who ate food prepared for them. The AOR was also about 16 times higher for dogs that scavenged and ate leftovers from households compared to those who ate food prepared for them. The findings of this study indicate that the prevalence of GI nematodes in domestic dogs in Kigali city, Rwanda, was 33.3% (95% CI: 23.8–42.9). The identified nematodes, namely, Ancylostoma spp. and Toxocara canis, are zoonotic, and dogs and humans are at risk of contracting these nematodes. The factors associated with canine GI nematodes in Kigali city include feeding practices and the dog’s age and location (district). Dog owners need to rethink procedures for deworming and feeding their dogs. Again, the public should be made aware of the role of dogs in transmitting zoonotic nematodes to humans.

While pig farming has been growing rapidly in Rwanda, its potential contribution to the prevalence of zoonotic infections is not well known. Pig production is usually affected by gastrointestinal parasites, some of which are zoonotic and can threaten human health. The knowledge about the status of such infections is essential for policy decisions and interventions. We aimed to investigate the prevalence of swine gastrointestinal parasites in Nyagatare district, Rwanda. A cross-sectional study involved collecting 104 faecal samples from apparently healthy pigs. The floatation technique was used to identify the parasites and frequency distribution analysis, and Pearson chi-square tests of association were conducted for this study data. Overall, the prevalence of swine gastrointestinal parasites was 84.6%, and the predominant species were Strongyle-type helminths representing 70.2%, followed by coccidia (55.8%), Strongyloides ransomi (39.4%), and Ascaris suum (10.6%). Of all parasitized pigs ( n = 88 ), 84.1% developed coinfections involving 2, 3, or 4 different parasite species. The results showed a statistically significant correlation between the location of pigs and parasitic infections and that some prevalent parasites are zoonotic. Interventions among pig farmers in Nyagatare should aim to improve awareness and to provide information on the negative impacts of swine gastrointestinal parasites on pig production and human health.

Goat farming significantly contributes to the efficient use of land and socioeconomic development in developed and developing countries. During the fiscal year 2017-2018, goats made up 13.5% of the total live livestock exported by Rwanda. Gastrointestinal parasites (GIPs) can negatively impact goat production, especially in developing countries like Rwanda. This study aimed to determine the impact of the goat' age and location (administrative cell) on the prevalence of gastrointestinal nematodes, cestodes, and protozoans (GiNCPs) of goats in Nyagatare district, Rwanda. Methods: In this cross-sectional study, 149 faecal samples were collected from apparently unwell goats and analyzed using the simple flotation technique. Strongyle-type nematodes (STNs) infections were graded using the McMaster method. Pearson chi-square tests of independence were calculated to assess the impact of the goat' age and location on the prevalence of GiNCPs in the study area. Results: All the goats (100%) were infected with GiNCPs. The identified types of parasites were STNs (96.0%), Coccidia (83.2%), Moniezia spp (14.8%), Strongyloides papillosus (12.8%), Nematodirus spp (0.7%) and Trichuris ovis (0.7%). Nearly 85.9% (128/149) of the goats were coinfected with 2 to 4 types of parasites and the coinfection of STNs and coccidia preponderated at 58.4%. The location (administrative cell) of the goats correlated with the prevalence of monieziasis (p<0.05). The goat's age category was also associated with the prevalence of strongyloidiasis (p<0.05). Conclusion: All the goats (100%) were infected with GiNCPs. The location (administrative cell) of the goat also correlated with the prevalence of monieziasis. In addition, the goat's age category was associated with the prevalence of strongyloidiasis. These findings show that any control program for caprine gastrointestinal parasitoses in the study area should focus on STNs and Coccidia.

Background Despite that canine helminthiases pose a public health risk to humans and livestock, the prevalence of canine helminthiases in Rwanda is unknown. This study aimed to determine the prevalence of canine helminthiases and to identify the risk factors of such infections in Kigali, the capital city of Rwanda. A cross-sectional study involved 93 dogs selected across Kigali city. Faecal samples were collected from clinically healthy dogs and eggs worms were identified using McMaster technique. Risk factors for canine helminthiases were analysed by multivariable binary logistic regression analysis. Results The overall prevalence of intestinal helminthiases in dogs was 39.8%. The most prevalent species was Ancylostoma spp (32.3%, n = 93). About 41.9% (n = 31) of dogs suffering from ancylostomosis and/or toxocarosis had high egg counts per gram (EPG) of faeces (≥ 550). Approximately 97.3% (n = 37) of dogs infected with helminths had mono-infection. Logistic regression analysis showed that dog's age and location were significantly associated with the prevalence of canine helminthiases. The adjusted odds ratio (AOR) of dogs suffering from helminthiases was more than 61% lower in dogs dewormed once to twice a year compared to those who were never dewormed. The AOR was more than 42% lower for restricted dogs compared to non-restricted ones. Conclusions All the identified helminths are zoonotic and they pose a public health risk to humans. There is urgent need of awareness among dog owners on the role of dogs in transmitting zoonotic helminthiases to other animals and humans as well as effective control measures.

Background: Canine helminthiases pose a public health risk to humans and livestock; however, the prevalence of canine helminthiases in Rwanda is unknown. This study aimed to determine the prevalence of canine helminthiases and to identify the risk factors of such infections in Kigali, the capital city of Rwanda. A cross-sectional study involved 93 dogs selected across Kigali city. Faecal samples were collected from apparently healthy dogs and helminth eggs were identified and quantified under microscope using McMaster technique. Risk factors for canine helminthiases were analysed by multivariable binary logistic regression analysis.Results: The overall prevalence of intestinal helminthiases in dogs was 39.8% ±5.08 (α=0.05). The most prevalent species was Ancylostoma spp with 32.3% ± 4.85 (30/93). About 38.7% and 3.4% (n= 31) of dogs suffering from ancylostomosis and/or toxocarosis had high egg counts per gram (EPG) of faeces (≥ 550) each. Approximately 97.3% (36/37) of dogs infected with helminths had mono-infection. Logistic regression analysis showed that dog's age (1 to 2. 5 years old and at least 5 years old) and location (Gasabo and Kicukiro) were significantly associated with the prevalence of canine helminthiases. The adjusted odds ratio (AOR) of dogs suffering from helminthiases was more than 61% lower in dogs dewormed once to twice a year compared to those who were never dewormed. In addition, the AOR was more than 5 times higher for dogs fed on raw animal origin supplements, leftovers from family food and restaurants compared to those who ate food prepared for them. The AOR was also more than 8 times higher for dogs that ate leftovers from household food and scavenged compared to those who ate food prepared for them. Conclusions: All the identified helminths including Ancylostoma spp, Toxocara canis, and tapeworms are zoonotic and they pose a public health risk to humans. There is an urgent need of increasing the awareness among pet owners on the role of dogs in the transmission of zoonotic helminthiases to other animals and also to humans. Moreover, it is highly relevant to inform and to take effective control measures in dog populations.
