The objectives of this study were to determine the characteristics of a dog population, including their accessibility to vaccination and health care, in urban and semiurban areas of Gwagwalada, Abuja, Nigeria. Direct street counts and a house‐to‐house survey of city streets were performed. A total of 451 households were surveyed comprising 43.7% urban and 53.3% semiurban areas. A total of 848 owned dogs were identified, along with 3,115 corresponding humans. With a dog‐to‐human ratio of 1:3.7, the dog population in the study area was estimated as 103,758. A total of 396 dogs were counted on the streets with the greater proportion (74%) in semiurban areas. Most dogs in semiurban areas (77.3%) had no certificate confirming vaccination against rabies, compared to 47.2% in urban areas (p = .004). The majority of dogs in the urban (60.9%) and semiurban (82.0%) were free roaming. In the multivariable model, age, presence of a collar, region, sex, use and having ever visited a veterinarian were significantly associated with rabies vaccination. The majority (125/197, 63.5%) of respondents with higher education were willing to pay more for the healthcare needs of their dogs as opposed to those with a lower level of education (93/251, 37.1%, p = .001). The study revealed a high dog population density, vaccination coverage below WHO recommendation of 70% and generally reduced healthcare‐seeking behaviour among dog owners in Gwagwalada, Abuja, Nigeria.  相似文献

Free‐roaming dog populations are a global concern for animal and human health including transmission of infectious disease (e.g. rabies, distemper and parasites), dog bite injuries/mortalities, animal welfare and adverse effects on wildlife. In Saskatchewan (SK), Canada, veterinary care is difficult to access in the remote and sparsely inhabited northern half of the province, where the population is predominately Indigenous. Even where veterinary clinics are readily available, there are important barriers such as cost, lack of transportation, unique cultural perspectives on dog husbandry and perceived need for veterinary care. We report the effects of introducing a community action plan designed to improve animal and human health, increase animal health literacy and benefit community well‐being in two Indigenous communities where a dog‐related child fatality recently occurred. Initial door‐to‐door dog demographic surveys indicated that most dogs were sexually intact (92% of 382 dogs), and few had ever been vaccinated (6%) or dewormed (6%). Approximately three animal‐related injuries requiring medical care were reported in the communities per 1000 persons per year (95% CL: 1.6–6.6), and approximately 86% of 145 environmentally collected dog faecal samples contained parasites, far above levels reported in other urban or rural settings in SK. Following two subsidized spay/neuter clinics and active rehoming of dogs, parasite levels in dog faeces decreased significantly (P < 0.001), and important changes were observed in the dog demographic profile. This project demonstrates the importance of engaging people using familiar, local resources and taking a community specific approach. As well, it highlights the value of integrated, cross‐jurisdictional cooperation, utilizing the resources of university researchers, veterinary personnel, public health, environmental health and community‐based advocates to work together to solve complex issues in One Health. On‐going surveillance on dog bites, parasite levels and dog demographics are needed to measure the long‐term sustainability of benefits to dog, human and wildlife health.  相似文献

This study investigated self‐reported dog bites in humans in rural and urban households in southern Ontario, Canada. Our objectives were to determine, and compare, the incidence of dog bites in rural and urban households, and to describe the profile of bite victims, biting dogs, and the proportion of biting dogs that respondents self‐reported as being not up to date on rabies vaccination. We conducted a cross‐sectional observational study using an online questionnaire. The 2,006 respondents, each representing one household, included 1,002 rural and 1,004 urban residences. The incidence risk of at least one person in the household being bitten over the previous year in rural households (6.09% per year) was less than in urban households (10.76% per year). In 53.20% of households from which at least one person had been bitten within the past year, only a single person had been bitten. Mostly, victims were 25 to 34 years old (21.67%), male (54.19%), and playing with or interacting with the biting dog at the time of the incident (59.11%). Most biting dogs were 3 to 5 years old (32.02%), males (53.69%), and unleashed (76.85%). Based on self‐reporting by respondents, 83.33% of respondent‐owned biting dogs were vaccinated against rabies at the time of the biting incident. Irrespective of dog ownership, the odds of an individual in a rural household being bitten by a dog were 0.53 (95% CI: 0.38–0.73) the odds for an individual in an urban household. Dog bites constitute a serious, yet preventable, public health concern that requires targeted, community‐specific efforts. Public health organizations could consider findings in developing messaging, particularly as we highlight biting dogs reported by their owners as not up to date on rabies vaccination.  相似文献

The Philippines has a long history of rabies control efforts in their dog populations; however, long‐term success of such programmes and the goal of rabies elimination have not yet been realized. The Bohol Rabies Prevention and Elimination Program was developed as an innovative approach to canine rabies control in 2007. The objective of this study was to assess canine rabies vaccination coverage in the owned‐dog population in Bohol and to describe factors associated with rabies vaccination 2 years after implementation of the programme. We utilized a cross‐sectional cluster survey based on the World Health Organization’s Expanded Programme on Immunization coverage survey technique. We sampled 460 households and collected data on 539 dogs residing within these households. Seventy‐seven per cent of surveyed households reported owning at least one dog. The human‐to‐dog ratio was approximately 4 : 1, and the mean number of dogs owned per household was 1.6. Based on this ratio, we calculated an owned‐dog population of almost 300 000. Overall, 71% of dogs were reported as having been vaccinated for rabies at some time in their lives; however, only 64% of dogs were reported as having been recently vaccinated. Dogs in our study were young (median age = 24 months). The odds of vaccination increased with increasing age. Dogs aged 12–23 months had 4.6 times the odds of vaccination compared to dogs aged 3–11 months (95% CI 1.8–12.0; P = 0.002). Confinement of the dog both day and night was also associated with increased odds of vaccination (OR = 2.1; 95% CI 0.9–4.9; P = 0.07), and this result approached statistical significance. While the programme is on track to meet its goal of 80% vaccination coverage, educational efforts should focus on the need to confine dogs and vaccinate young dogs.  相似文献

Australia is unique as a populated continent in that canine rabies is exotic, with only one likely incursion in 1867. This is despite the presence of a widespread free‐ranging dog population, which includes the naturalized dingo, feral domestic dogs and dingo‐dog cross‐breeds. To Australia's immediate north, rabies has recently spread within the Indonesian archipelago, with outbreaks occurring in historically free islands to the east including Bali, Flores, Ambon and the Tanimbar Islands. Australia depends on strict quarantine protocols to prevent importation of a rabid animal, but the risk of illegal animal movements by fishing and recreational vessels circumventing quarantine remains. Predicting where rabies will enter Australia is important, but understanding dog population dynamics and interactions, including contact rates in and around human populations, is essential for rabies preparedness. The interactions among and between Australia's large populations of wild, free‐roaming and restrained domestic dogs require quantification for rabies incursions to be detected and controlled. The imminent risk of rabies breaching Australian borders makes the development of disease spread models that will assist in the deployment of cost‐effective surveillance, improve preventive strategies and guide disease management protocols vitally important. Here, we critically review Australia's preparedness for rabies, discuss prevailing assumptions and models, identify knowledge deficits in free‐roaming dog ecology relating to rabies maintenance and speculate on the likely consequences of endemic rabies for Australia.  相似文献

In this survey, the prevalence of canine gastrointestinal helminths in Finland was investigated by coprological examination (n = 541) and possible risk factors for helminth infections in dogs were analysed. In addition, the dog owners (n = 296) completed a questionnaire about use of anthelmintics, sources of information about parasites and antiparasitic treatments and reasons for choosing the drugs.

The prevalence of gastrointestinal helminths was 5.9%. Eggs from four different species were identified in the faecal samples. Toxocara canis eggs were present in 17 dogs (3.1%), Uncinaria stenocephala eggs in 14 dogs (2.6%) and Diphyllobothrium latum eggs in 2 dogs (0.4%). Moreover, one sample contained eggs of Trichuris vulpis (0.2%). Kennel housing and visits abroad were identified as risk factors for T. canis and U. stenocephala infections.

Most dogs (86.0%) received anthelmintic treatment at least once a year. Hunting dogs were dewormed least; one-third was treated less than once a year. Approximately, half of the owners occasionally changed the anthelmintic used. The most important trait of the anthelmintic was its broad spectrum, fenbendazole being the most commonly chosen. Veterinarians, dog magazines and dog breeders were the predominant sources of information concerning parasites and deworming strategies.  相似文献

This article describes and contrasts the public health response to two human rabies cases: one organ recipient diagnosed within days of symptom onset and the transplant donor who was diagnosed 18 months post‐symptom onset. In response to an organ‐transplant‐related rabies case diagnosed in 2013, organ donor and recipient investigations were conducted by multiple public health agencies. Persons with potential exposure to infectious patient materials were assessed for rabies virus exposure. An exposure investigation was conducted to determine the source of the organ donor's infection. Over 100 persons from more than 20 agencies spent over 2700 h conducting contact investigations in healthcare, military and community settings. The 564 persons assessed include 417 healthcare workers [5.8% recommended for post‐exposure prophylaxis (PEP)], 96 community contacts (15.6% recommended for PEP), 30 autopsy personnel (50% recommended for PEP), and 21 other persons (4.8% recommended for PEP). Donor contacts represented 188 assessed with 20.2% recommended for PEP, compared with 5.6% of 306 recipient contacts recommended for PEP. Human rabies cases result in substantial use of public health and medical resources, especially when diagnosis is delayed. Although rare, clinicians should consider rabies in cases of encephalitis of unexplained aetiology, particularly for cases that may result in organ donation.  相似文献

International dog imports pose a risk because of the potential movement of disease agents, including the canine rabies virus variant which has been eliminated from the United States since 2007. US regulations require a rabies vaccination certificate for dogs arriving from rabies‐endemic countries, but permit the importation of dogs that have not been adequately immunized against rabies, provided that the dogs are confined under conditions that restrict their contact with humans and other animals until they have been immunized. CDC Form 75.37, ‘Notice to Owners and Importers of Dogs’, explains the confinement requirements and serves as a binding confinement agreement with the importer. In this evaluation, we describe the characteristics of unimmunized dogs imported into the United States over a 1‐year period based upon dog confinement agreements recorded at the Centers for Disease Control and Prevention (CDC) quarantine stations. Confinement agreements were issued for nearly 2800 unimmunized dogs that entered the United States during 1 June 2011–31 May 2012, the majority of which travelled to the United States by air and without any seasonal pattern in import volume. Over 60% of these animals were puppies <3 months of age and included a wide variety of breeds. The dogs arrived from 81 countries, with the majority arriving from North America or Europe. Dogs placed on confinement agreements had final destinations in 49 states. California, New York, Texas, Washington and Florida received the largest number of dogs on confinement agreements. These results (which do not reflect human travel or US dog ownership data) suggest that a large portion of unimmunized dogs arrive from rabies‐endemic countries for commercial, shelter and rescue purposes. Further evaluation and key stakeholder involvement are needed to assess whether the current dog importation regulations are an adequate compromise between the benefits and risks of dog importation.  相似文献

Canine rabies vaccination is delivered in Thungsong District, Thailand, as an annual campaign between March 1 and 31, and also at other times through private veterinary clinics, para-veterinarians and health-care staff residing in the villages. The current questionnaire-interview survey was conducted between June 23 and July 18, 2002 to determine: rabies-vaccination coverage amongst the owned-dog population; basic dog-population information; and community awareness about rabies. The modified expand programme on immunization cluster-survey method was used to collect information about dog demography and management characteristics. Household knowledge about rabies and sources of rabies information were assessed. Vaccinated dogs were identified from vaccine certificates or owner reports confirmed by vaccinators. Seventy percent (95%CI 62-78) of 364 eligible owned dogs were vaccinated within the 6 months prior to data collection. Of these 255 vaccinated dogs, 44, 21, 13, 17 and 5% were vaccinated through the annual vaccination campaign, veterinary clinics, para-veterinarians, other vaccinators and owners, respectively. Fifty-four percent of households owned dogs. The sex ratio in dogs was 2 males per female; the dog: human ratio was 1: 4.6 with an average of 0.9 dogs per household (1.7 dogs per dog-owning household). Most dogs roamed freely and these were less likely to be vaccinated compared to dogs being kept on premises or on a leash. Almost all households were aware of rabies and the need for dog rabies vaccination as a control method. Seventy-six percent believed that rabies only occurred in summer. There was little awareness about cat rabies amongst households. Vaccination coverage in the total dog population clearly has not yet reached the 80% target level set by Thailand's official rabies-control programme. Improved effectiveness of the owned-dog rabies-vaccination campaigns in each community is needed-perhaps by more community education about dog management or by better management of ownerless dogs.  相似文献

This study aimed to examine the habits of dog walking in Japan using an internet survey of insured dog owners. About 96.4% of the respondents (n = 1,151) reported that they would take their dogs for a walk and they most frequently walk their dogs once or twice a day (75.9%) for 30 min to 1 hr (83.1%). The probability of a companion dog having contact with other dogs during dog walking was estimated to be 0.83 (95% confidence interval [CI]: 0.81–0.85), and the associated daily contact rate was estimated using log‐normal distribution with a mean of 2.73 (95% CI: 2.42–3.11) and a standard deviation (SD) of 6.39 (95% CI: 5.18–7.84). Multiple linear regression revealed that the contact rate is mainly influenced by the social behaviour of the owner and to a lesser degree by his/her demographic characteristics including the area of residence, the breed size of dog and the age of the owner. In addition, ten Likert items measured on a 5‐point scale were designed to assess the practices towards potential cases of rabies among dog owners. The respondents (n = 972) achieved a mean score of 2.99 (out of a full score of 4) with a SD of 0.90 in responding to situations related to dog bite incidents and injury from stray cat scratches during dog walking. They achieved a higher score in responding to situations related to sighting a stray or wild animal during dog walking and situations related to non‐specific clinical signs of rabies and bite injuries from stray dogs or wild animals during dog walking with a mean of 3.70 (SD = 0.58) and 3.84 (SD = 0.34), respectively. The level of best practice was also proved to be significantly associated with the demographic characteristics of the dog owner.  相似文献

US animal shelters house and care for dogs with unknown medical histories. Such unknown medical backgrounds pose concern for zoonotic transmission of diseases to the shelter staff. One important zoonotic exposure is to rabies virus which is almost always fatal after the onset of symptoms. The objective of this study was to identify the characteristics of dog shelters associated with the probability that the shelter had a policy to vaccinate shelter personnel against rabies. Five states with an established shelter registry were selected from each geographic region of the United States. A list of shelters within those states was developed from the registry list, through Internet searches and comparisons with other known lists. At least two forms of direct communication were used to ensure that humane organizations met the study definition of a dog shelter. In total, 342 of 461 (73%) shelters that met the study definition were visited by a team of students. Forty‐two of 332 (13%) shelters responding to the question required staff to be vaccinated against rabies. Logistic regression was utilized to test shelter characteristics for association with the probability that they have a rabies vaccination policy for shelter staff. Municipally funded shelters were more likely to vaccinate staff for rabies than shelters funded privately (OR = 3.0, 95% CI = 1.40–6.39). These results demonstrate that shelter funding source may influence rabies control programmes in shelters.  相似文献

Canine vaccination--providing broader benefits for disease control   总被引：3，自引：0，他引：3  
This paper reviews the broader benefits of canine vaccination to human and animal health and welfare with an emphasis on the impacts of mass dog vaccination against rabies in countries of the less-developed world. Domestic dogs are the source of infection for the vast majority (>95%) of cases of human rabies worldwide, and dogs remain the principal reservoir throughout Africa and Asia. Canine vaccination against rabies has been shown to dramatically reduce the number of cases in dogs, the incidence of human animal-bite injuries (and hence the demand for costly post-exposure prophylaxis) and the likely number of human cases, primarily in children. Further benefits include the mitigation of the psychological consequences of rabies in a community, improved attitudes towards animals and animal welfare and reduced livestock losses from canine rabies. Mass vaccination has recently been used in the conservation management of wild carnivore populations threatened by transmission of rabies and canine distemper virus from domestic dog populations. Vaccination of wildlife hosts directly may also provide an option for mitigating infectious disease threats. The development of integrated control measures involving public health, veterinary, wildlife conservation and animal welfare agencies is needed to ensure that control of canine diseases becomes a reality in Africa and Asia. The tools and delivery systems are all available--all that is needed is the political will to free the world from the ongoing tragedy of these diseases.  相似文献

The current European Union (EU) legislation decrees that pets entering the EU from a rabies‐infected third country have to obtain a satisfactory virus‐neutralizing antibody level, while those moving within the EU require only rabies vaccination as the risk of moving a rabid pet within the EU is considered negligible. A number of factors driving individual variations in dog vaccine response have been previously reported, including a high rate of vaccine failure in puppies, especially those subject to commercial transport. A total of 21 001 observations collected from dogs (2006–2012) vaccinated in compliance with the current EU regulations were statistically analysed to assess the effect of different risk factors related to rabies vaccine efficacy. Within this framework, we were able to compare the vaccination failure rate in a group of dogs entering the Italian border from EU and non‐EU countries to those vaccinated in Italy prior to international travel. Our analysis identified that cross‐breeds and two breed categories showed high vaccine success rates, while Beagles and Boxers were the least likely to show a successful response to vaccination (88.82% and 90.32%, respectively). Our analysis revealed diverse performances among the commercially available vaccines, in terms of serological peak windows, and marked differences according to geographical area. Of note, we found a higher vaccine failure rate in imported dogs (13.15%) than in those vaccinated in Italy (5.89%). Our findings suggest that the choice of vaccine may influence the likelihood of an animal achieving a protective serological level and that time from vaccination to sampling should be considered when interpreting serological results. A higher vaccine failure in imported compared to Italian dogs highlights the key role that border controls still have in assessing the full compliance of pet movements with EU legislation to minimize the risk of rabies being reintroduced into a disease‐free area.  相似文献

Serum samples from 254 non vaccinated and apparently healthy dogs of local breeds in Nsukka environs, Nigeria were examined for the presence of antibodies to rabies virus by haemagglutination-inhibition technique. The prevalence rates of rabies antibodies in, less than 3 months, 3-6 months, and over 6 months old dogs were 17.5%, 7.3% and 22.8% respectively, and overall 16.1% in the dog population. This was the first documented report of rabies antibodies in non vaccinated dogs in Eastern Nigeria. The results were discussed with respect to the epidemiology of prototype rabies and rabies-related viruses. It was suggested that the antibodies were most probably due to the non virulent prototype rabies or rabies-related virus strains. 83.9% of susceptible dogs in the population suggested a mandatory regular a vaccination of all dogs in interest of public health and control of the disease. The study highlighted the need for more studies on epidemiology of rabies and rabies-related viruses in Nigeria.  相似文献

Dogs are often present on livestock farms, where they serve important management and companion roles, yet may be involved in zoonotic pathogen transmission. Numerous factors can potentially alter the risk of exposure to zoonotic pathogens, such as the dog's access to livestock, close dog–human contact and an increasing immunocompromised human population. The objective of this study was to quantify and qualify dog ownership among livestock owners, their dog husbandry and biosecurity practices, the dogs’ access to livestock and potential risks for zoonotic pathogen transmission. A questionnaire was developed and mailed to 2,000 presumed Ohio livestock owners. Data were collected on demographics, dog husbandry practices, attitudes surrounding zoonotic diseases and attachment to and preventive veterinary care for the dogs. There were 446 responders who met the study inclusion criteria as an Ohio livestock farm owner, with 297 (67%) also owning dogs. Approximately 52% of dog‐owning households included at least one individual at higher disease risk (i.e., <5 years, ≥65 years, diagnosed with an immunocompromising condition). Most respondents had little/no concern for disease transmission from livestock to dogs (90%), from dogs to livestock (87%) and from dogs to people (94%). Dogs were allowed access to livestock by 70% of respondents and nearly all (96%; 198) indicated at least one higher risk dog–livestock management practice. In addition, many reported never leashing or fencing their dog (61%) and rarely to never picking up dog faeces (76%). Households with higher risk members reported similar husbandry, biosecurity and concern levels as households without those members (all p > .05). Numerous opportunities for zoonotic pathogen transmission and low level of zoonotic disease concern suggest a need for improved education and outreach for the livestock dog‐owning community, particularly for higher risk households.  相似文献

Dogs have been implicated in the zoonotic transmission of numerous pathogens. Whereas cats are known to transmit Francisella tularensis to humans via bite and other routes, the role of dogs in facilitating infection is much less understood. We reviewed tularaemia case investigation records collected through national surveillance during 2006–2016 to summarize those with dog involvement, characterize the nature of dog‐related exposure and describe associated clinical characteristics. Among 1,814 human tularaemia cases, 735 (41%) supplemental case investigation records were available for review; and of those, 24 (3.3%) were classified as dog‐related. Median age of patients was 51 years (range: 1–82); 54% were female. Two thirds (67%) of cases presented with ulceroglandular/glandular tularaemia; pneumonic (13%) and oropharyngeal (13%) illness occurred less frequently. Dog‐related exposures were classified as follows: direct contact via bite, scratch or face snuggling/licking (n = 12; 50%); direct contact with dead animals retrieved by domestic dogs (n = 8; 33%); and contact with infected ticks acquired from domestic dogs (n = 4; 17%). Prevention of dog‐related tularaemia necessitates enhanced tularaemia awareness and tick avoidance among pet owners, veterinarians, health care providers and the general public.  相似文献

OBJECTIVES: To understand the epidemiology of animal bites and exposure, evaluate the animal exposure reporting system for surveillance of rabies postexposure prophylaxis (PEP), and identify opportunities to reduce PEP. DESIGN: Period prevalence survey. STUDY POPULATION: Pennsylvania residents in 1995. PROCEDURE: Data from animal bite reports from Pennsylvania county health offices were summarized for 1995. Animal bite incidences for the state, counties, various age groups, and various population densities were calculated. Animal species, treatment, location of wounds, and PEP recommendations were evaluated for exposures. RESULTS: More than 16,000 animal-related potential rabies exposures were reported from 65 of 67 counties in Pennsylvania. The highest incidence was in children less than 5 years old (324/100,000). Of the 75% of victims requiring wound treatment, 50% received antimicrobials, 29% received a tetanus toxoid, and 19% had wounds sutured, were admitted to hospitals, or were referred for plastic surgery. Although 75% of exposures were to dogs, victims exposed to cats were 6 times as likely to receive PEP (relative risk, 6.1; 95% confidence interval, 5.1 to 7.4). Thirty percent of 556 PEP were given for exposures to dogs, 44% for cats, 7% for raccoons, 4% for bats, 2.5% for squirrels, 2.1% for groundhogs, 2% for foxes, and 8% for exposures to other species. Fifty-nine percent of owned dogs were up-to-date on rabies vaccinations compared with 41% of owned cats. CONCLUSION: Interventions, such as dog bite prevention education, vaccination of pets against rabies, appropriate use of PEP, and reduction of feral cat populations, should be instituted, enhanced, or better enforced in communities.  相似文献

A random sample survey using personal interviews was conducted in Zimbabwe in 1986 to determine the size and structure of the national dog population and its level of rabies vaccination. There was an average of 0.91 dogs per household in Zimbabwe giving an extrapolated total population of 1,308,577 dogs. There was a dog to people ratio of 1:6.5 and an average of 3.4 dogs per square kilometre. The ratio of adult male to female dogs was 0.56:0.44, with 20 per cent of the dog population being less than three months old. In the period 1950 to 1986 there was a 4.7 per cent per annum growth rate of the dog population. In one of the provinces, Manicaland, dogs were found to have an average age of 2.3 years and a life expectancy at birth of 4.6 years. An estimated 40 per cent of the dog population three months old and above had been vaccinated against rabies in 1985/1986. With the rabies incidence in Zimbabwe still unacceptably high this level of vaccination is clearly inadequate and measures designed to increase it are discussed.  相似文献
