BackgroundDog bites in humans are a public health problem worldwide. The issues of increasing stray dog populations, rabies outbreaks, and the risk of dogs biting humans have been frequently reported by the media in Bhutan. This study aimed to estimate the bite incidence and identify the risk factors for dog bites in humans, and to estimate human deaths from rabies in rabies endemic south Bhutan.MethodsA hospital-based questionnaire survey was conducted during 2009–2010 among dog bites victims who visited three hospitals in Bhutan for anti-rabies vaccine injection. Decision tree modeling was used to estimate human deaths from rabies following dog bite injuries in two rabies endemic areas of south Bhutan.ResultsThree hundred and twenty four dog bite victims were interviewed. The annual incidence of dog bites differed between the hospital catchment areas: 869.8 (95% CI: 722.8–1022.5), 293.8 (240–358.2) and 284.8 (251.2–323) per 100,000 people in Gelephu, Phuentsholing and Thimphu, respectively. Males (62%) were more at risk than females (P<0.001). Children aged 5–9 years were bitten more than other age groups. The majority of victims (71%) were bitten by stray dogs. No direct fatal injury was reported. In two hospital areas (Gelephu and Phuentsholing) in south Bhutan the annual incidence of death from rabies was 3.14 (95% CI: 1.57–6.29) per 100,000 population. The decision tree model predicted an equivalent annual incidence of 4.67 (95% CI: 2.53–7.53) deaths/100,000 population at risk. In the absence of post exposure prophylaxis, the model predicted 19.24 (95% CI: 13.69–25.14) deaths/year in these two areas.ConclusionsIncreased educational awareness of people about the risk of dog bites and rabies is necessary, particularly for children in rabies endemic areas of Bhutan.

Beginning January 2012, a humane method of dog population management using a Catch-Neuter-Vaccinate-Release (CNVR) program was implemented in Dhaka City, Bangladesh as part of the national rabies control program. To enable this program, the size and distribution of the free-roaming dog population needed to be estimated. We present the results of a dog population survey and a pilot assessment of the CNVR program coverage in Dhaka City. Free-roaming dog population surveys were undertaken in 18 wards of Dhaka City on consecutive days using mark-resight methods. Data was analyzed using Lincoln-Petersen index-Chapman correction methods. The CNVR program was assessed over the two years (2012–2013) whilst the coverage of the CNVR program was assessed by estimating the proportion of dogs that were ear-notched (processed dogs) via dog population surveys. The free-roaming dog population was estimated to be 1,242 (95 % CI: 1205–1278) in the 18 sampled wards and 18,585 dogs in Dhaka City (52 dogs/km2) with an estimated human-to-free-roaming dog ratio of 828:1. During the two year CNVR program, a total of 6,665 dogs (3,357 male and 3,308 female) were neutered and vaccinated against rabies in 29 of the 92 city wards. A pilot population survey indicated a mean CNVR coverage of 60.6% (range 19.2–79.3%) with only eight wards achieving > 70% coverage. Given that the coverage in many neighborhoods was below the WHO-recommended threshold level of 70% for rabies eradications and since the CNVR program takes considerable time to implement throughout the entire Dhaka City area, a mass dog vaccination program in the non-CNVR coverage area is recommended to create herd immunity. The findings from this study are expected to guide dog population management and the rabies control program in Dhaka City and elsewhere in Bangladesh.

Rabies is a serious public health problem in Asia. It causes substantial animal welfare, economic and human health impacts, with approximately 39,000 human deaths each year. Domestic dogs are the main reservoir and source of rabies in Asia. Common constraints for the control of rabies in the countries of Asia include inadequate resources; lack of political commitment to control programs; lack of consensus on strategy; weak intersectoral coordination and inadequate management structure; insensitive surveillance systems; limited accessibility to modern rabies vaccine and supply problems; lack of public awareness and public cooperation; and the existence of myths and religious issues. In this review, we summarize the epidemiology of rabies in both human and animals in each South and South East Asian country, the past and current approaches to control and the prospect for rabies elimination. We conclude that defining the cost of rabies to society and communicating this to decisionmakers might be the key to achieving such an advance.

SUMMARYWe report a major outbreak of rabies in dogs and other domestic animals that occurred in eastern Bhutan between May 2005 and November 2007. The outbreak peaked in February 2006 and subsided by the end of April 2006 with sporadic cases reported until November 2007. Rabies affected 18 of the 40 sub-districts in the three eastern districts of Bhutan. There were reportedly one human and 256 domestic animal fatalities. The outbreak affected cattle (n=141, 55%), dogs (n=106, 41%), horses (n=7, 3%) and cats (n=2, 1%). Rabies was primarily diagnosed by clinical signs but 36 cases were confirmed by fluorescent antibody test of brain samples. High densities and movements of free-roaming dogs might have been responsible for the rapid spread and persistence of the infection for a longer period than expected in dogs in eastern Bhutan.

Introduction Antimicrobial resistance is (AMR) an emerging global public health problem. Rationale use of antibiotic can prevent the rise of antimicrobial resistance. The objective of this study was to understand the knowledge, attitude and practice on antibiotic usage and AMR among the veterinarians and para-veterinarians in Bhutan. Method A cross-sectional questionnaire survey among the veterinarians and para-veterinarians was conducted from June to July 2020. A score of one to the correct answers and zero for the wrong answers was allotted to each respondent answers. The total score was added and those who scored above the mean was categorized as having good knowledge and favourable attitude. Result A total of 219 animal health workers participated in this study. The mean knowledge score was 12.05 ±1.74 with 38.8% of the respondents having good knowledge on antibiotic use and AMR. Similarly, the mean scores for the attitude level were 8.32±1.61 with 51% them having favorable attitude towards antibiotic usage and AMR. The mean practice score was 3.83±1.06 with 77% of them having good practices on antibiotic use. The respondents who read national plan on AMR were found to have good knowledge on antibiotics and AMR (AOR: 2.39; 95% CI: 1.19–4.82). The female respondents (AOR: 2.16; 95% CI: 1.01–4.61), respondents from the eastern region (AOR: 2.53; 95% CI: 1.18–5.44), west central (AOR: 3; 95% CI: 1.30–6.92), animal health supervisors (AOR: 9.77; 95% CI: 1.98–48.29), and livestock production supervisors (AOR: 2.77; 95% CI: 1.21–6.35) have favorable attitude towards antibiotics and AMR. Conclusions Our study identified that most animal health workers in Bhutan had poor knowledge on antibiotics usage and AMR. Therefore, regular awareness education on antibiotics and AMR in the form of refresher course/training must be provided to the animal health workers in the country to avoid inappropriate use of antibiotics.

This is a pre-copyedited, author-produced PDF of an article published in [Vaccine] AbstractThe aim of this study was to understand the use and distribution of human rabies post exposure prophylaxis (PEP) vaccine in Bhutan and to identify risk factors for receiving an incomplete course of the vaccine. We analysed post exposure treatment records from 28 medical hospitals from 2005 to 2008. Males (59%) accounted for significantly more PEP events than females (41%) across all age groups (P < 0.001). Children-particularly 5-9 years of age -received more rabies PEP than other age groups. Animal bite and non-bite accounted for 27% (n = 2239) and 16% (n = 1303) of rabies PEP, respectively, whilst 57% (n = 4773) of the PEP events had no recorded information about the reasons for post exposure treatment. Post exposure treatment was provided throughout the year with a higher number during the winter and spring months. The number of PEP events significantly (P < 0.001) increased between 2005 and 2008, from <1000 to >2800 events, respectively. Significantly (P < 0.001) more PEP events were reported from the southern parts of Bhutan that are endemic for rabies or those areas in eastern Bhutan that have reported rabies outbreaks than other parts of Bhutan. Forty percent (n = 3360) of the patients received an incomplete course of vaccine (<5-doses of vaccine intramuscular). Results suggest that patients with animal bite injury were less likely to receive an incomplete vaccine course than nonbite recipients, and patients presented to hospitals in rabies endemic or outbreak areas were less likely to receive an incomplete course than in non-rabies areas or rabies free areas. Similarly, patients presenting to hospitals for PEP during spring and summers months were less likely to receive an incomplete vaccine course than those during other seasons. Public education campaigns need to be conducted in Bhutan to reduce dog bite incidents and also to prevent mass exposures to rabies. A thorough assessment of each individual case based on the WHO guidelines would reduce unnecessary PEP (and therefore costs) in Bhutan.
