Trends in Animal Bites and Rabies-related Deaths in Northern Iran: Implications for Public Health Interventions.

BACKGROUND: Rabies remains a public health problem in middle-income countries like Iran, despite being preventable. This study aimed to evaluate the six-year incidence of animal bites in the southern Caspian Sea region from 2016 to 2022, and focus on estimating the direct costs of animal bite cases using the incidence-based method. METHODS: A multicenter, registry-based study was conducted using surveillance data of animal bites. RESULTS: Of the 40922 cases reported during the study period, 65.9% were male and 34.1% were female. Animal bites were most frequent among individuals over 50 years of age (23.5%), while children under 10 years of age had the lowest frequency of animal bites (2.3%). Animal bites were most common in June. Dogs were responsible for 33277 (81%) cases, cats for 5,624 (13.7%) cases, cows for 1054 (2.5%) cases, and other animals for the remaining cases. During the six-year study period, four deaths due to rabies were reported in the study area. The annual bite incidence rate was 386.3 per 100000 people in northern Iran. The males-to-female ratio was highest in 2019 (M/F ratio=2.4, 95% CI=1.2‒3.4). CONCLUSION: The elderly are at higher risk of animal bites, especially in rural areas. It is important to emphasize the use of protective clothing, washing wounds with soap water and rabies vaccination as initial treatment. Targeted vaccination efforts for eligible animals should be prioritized to minimize unnecessary financial burden. Educating farmers about rabies prevention programs, especially in cases of cow bites, is also important.

An assessment of the operationality and factors influencing the effectiveness of rabies surveillance in Gombe State, Nigeria.

Rabies remains a burden in Africa, disproportionately affecting the most vulnerable despite the availability of effective vaccines. Nigeria, the most populous African country, needs rapid disease control actions and commitments to achieve the goal of eliminating dog-mediated rabies by 2030. Surveillance is an essential element of effective disease control strategies. This study examined the current state of operationality of the rabies surveillance system for early case detection and management in Gombe state, Nigeria, through a One Health lens. It further examined the barriers impeding the effectiveness of the surveillance based on the perception of surveillance workers. Qualitative and quantitative methods were used to assess the structure of the system and its functioning. Data on dog bite and rabid cases obtained from the veterinary services in Gombe state were analysed descriptively. A total of 13 key informants were interviewed using a semi-structured interview guide. Qualitative data were analysed using thematic analysis to explore in depth the factors that influenced the operationality of the system. A total of 157 potential human exposures to rabies were identified in this study, out of which two people reportedly died at the health facility after showing symptoms highly suggestive of rabies. In terms of rabies surveillance and control, cross-sectoral collaboration was found between the human health and veterinary sectors for risk assessment of potential rabies exposures and its management. Some identified factors affecting the operations of the surveillance were inadequate funding, lack of infrastructure, lack of feedback from higher authorities and insufficient knowledge of rabies prevention and management. To improve the capacity for case detection and management within the state, the appropriate authorities may focus on increasing awareness about the disease to the populace to increase the number of cases identified by the system, employ more workers and strengthen the surveillance capability of existing workers.

A two-year retrospective cohort study investigating the occurrence and short-term outcomes of dog-bite injures in regional Western Australia.

BACKGROUND: Dog bite injuries are a preventable yet common cause of animal related hospitalisation. Dog bites in metropolitan areas have been well characterised however there is limited information regarding dog bites in regional areas. This study sought to describe the demographics, clinical presentation and short-term outcomes of patients presenting with dog bite related injuries to Broome Regional Hospital (BRH). METHODS: A retrospective cohort study examined all dog bite related injuries presenting to BRH Emergency Department (ED) between July 1st 2021 - June 30th 2023, with the terms "dog" AND "bitten OR bite" in ED triage note. Chart review was performed to extract demographics, clinical presentation and short-term outcomes of dog bite related injuries. RESULTS: After exclusions, 207 patients were identified during the 2-year study period; approximately four dog-bites per week. Median age was 32 (IQR: 32, range 1-97 years old) with 46 % of patients being female. Residents of the Kimberley represented 78 % of presentations for dog bites. Dogs that belonged to or were known to patients were involved in 74 % of cases. The lower limb below the knee (42 %) was most commonly bitten, followed by the distal upper limb (30.5 %) and then face (13 %). Most patients presented on the same-day (67 %), were treated with antibiotics (79 %) and 83 % were discharged on the day of presentation. There were 43 (23 %) patients who required repair in the ED or operating theatre. Thirty-three patients were admitted to BRH. Seven patients required transfer for subspecialty tertiary level care. CONCLUSION: Dog-bite trauma is common and consumes significant health resources associated with ED presentations, hospital admissions, theatre usage and transfer in severe cases. A multifaceted approach encompassing education, engineering, and enforcement is required to prevent dog bites.

An Observational Study of Patient Characteristics and Environmental Risk Factors of Stingray Envenomations in San Diego, California.

INTRODUCTION: Current literature on stingray envenomations focuses on the incidence, presentation, and complications of these injuries, with some studies providing such data for specific geographic locations. This is the first study to evaluate the influence of environmental factors and human characteristics on stingray envenomation patterns in San Diego, California. METHODS: Incident reports of injuries documented by the San Diego Fire-Rescue Department/Lifeguard Division (SDFR-LG) during 2017 were analyzed. Water temperature and tide height were populated based on date and time. Data was analyzed for associations between stingray injuries incidence and tide height, water temperature, time, month, age and sex of the injured person, and whether they were local. RESULTS: 1722 stingray injuries were reported to the SDFR-LG in 2017. Stingray injuries were associated with water temperature (p < 0.001), more frequently occurring between 18.8 °C and 19.5 °C. Most envenomations occurred at tide heights between 1.7 ft and 3.1 ft. Most victims were aged 20-29, and there were more males than females injured. Beaches separated from the greater ocean or with a reef bottom had a lower incidence. Stingray injuries were more frequent during summer months. More stingray envenomations were documented for out-of-town beachgoers. CONCLUSIONS: Beachgoers with certain characteristics had more reported stingray envenomations than others. Males, nonlocal beachgoers, and individuals in their twenties had more injuries than their counterparts. Stingray injuries were more common at water temperatures between 18.8 and 19.5 °C. These findings may lead to future research on the prevention of stingray injuries.

Emergency department visits for dog bite injuries in Missouri municipalities with and without breed-specific legislation: a propensity score-matched analysis.

Breed-Specific Legislation is a type of law that bans or restricts ownership of specific dog breeds. Some local governments - including over seventy municipalities in the state of Missouri - have enacted Breed-Specific Legislation to prevent injuries from dog bites. Several studies from the peer-reviewed literature have found that aggressive behavior is not associated with any particular dog breeds and, since 2018, at least a dozen municipalities in Missouri have repealed these laws. To evaluate the impact of Breed-Specific Legislation on public safety, the 2010-2015 rates of emergency department visits for dog bite-related injuries in Missouri municipalities with and without Breed-Specific Legislation were compared. Propensity-score matched negative binomial regression models were used to assess the effect of breed restrictions on injury rates while balancing the samples on population characteristics and estimates of dog ownership. After matching the sample on population, housing and dog ownership estimates, no association was found between emergency department visits for dog bite injuries and whether the municipality enacted Breed-Specific Legislation. However, the incidence rate ratio of emergency room visits for dog bite-related injuries increased by 13.8% for every 1% increase in the percentage of males aged 5 to 9 in the population (p < 0.01). This study has found breed discriminatory laws have not reduced the risk of emergency department visits for injury from dog bites in Missouri. There appears to be no greater risk to public safety as local governments move to repeal existing breed bans.

Exposure History, Post-Exposure Prophylaxis Use, and Clinical Characteristics of Human Rabies Cases: A Twelve-Year Retrospective Review at a Tertiary Facility in Ghana.

BACKGROUND: Robust monitoring and reporting systems for rabies are lacking thus increasing the risk of underreporting. Highlighting the rabies cases brings to bear the needed urgent attention for more efforts at preventing and controlling the disease. OBJECTIVE: To describe the epidemiological characteristics of patients managed for clinical rabies at the largest referral facility in Ghana. METHODS: A retrospective single-center hospital-based chart review and data extraction were conducted for persons managed for clinical rabies infection at the Korle-Bu Teaching Hospital from January 2008 to December 2019. Data analysis was done using STATA. Descriptive statistics were used to summarize the epidemiological and clinical characteristics. Fisher's exact test, the Kruskal-Wallis test, and Spearman's correlation coefficient were used to explore significant associations. RESULTS: A total of 28 cases were recorded over the period of review. All of them died and most (68%) of them were males. Twenty-one percent of them were less than 15 years old. Their median age interquartile range (IQR) was 31 years (25.5 years) and the median incubation period for rabies (IQR) was 60 days (60 days). The source of rabies for cases was mainly dog bites. The vaccination status of all the animals could not be ascertained. Majority (80%) of the patients took neither anti-rabies vaccine nor immunoglobulin as post-exposure prophylaxis after the dog bite. The median time of admission before death (interquartile range) was 2 days (2 days). Majority (82%) of the cases were furious rabies. CONCLUSION: Attention should be directed at mass vaccination of dogs as dog bites are common. Ensuring availability and access to post-exposure prophylaxis (PEP) is also critical in averting rabies-related deaths.

CONTEXTE: Des systèmes de surveillance et de déclaration robustes pour la rage font défaut, augmentant ainsi le risque de sousdéclaration. Mettre en lumière les cas de rage suscite l'attention urgente nécessaire pour redoubler d'efforts dans la prévention et le contrôle de la maladie. OBJECTIF: Décrire les caractéristiques épidémiologiques des patients traités pour une rage clinique dans le plus grand établissement de référence au Ghana. MÉTHODES: Une revue rétrospective des dossiers médicaux et une extraction de données basées à l'hôpital ont été réalisées pour les personnes traitées pour une infection à la rage clinique à l'Hôpital d'Enseignement Korle-Bu de janvier 2008 à décembre 2019. L'analyse des données a été effectuée à l'aide de STATA. Des statistiques descriptives ont été utilisées pour résumer les caractéristiques épidémiologiques et cliniques. Le test exact de Fisher, le test de Kruskal-Wallis et le coefficient de corrélation de Spearman ont été utilisés pour explorer les associations significatives. RÉSULTATS: Un total de 28 cas ont été enregistrés sur la période examinée. Tous sont décédés et la plupart d'entre eux (68%) étaient des hommes. Vingt et un pour cent d'entre eux avaient moins de 15 ans. Leur âge médian (plage interquartile) était de 31 ans (25,5 ans) et la période d'incubation médiane de la rage (plage interquartile) était de 60 jours (60 jours). La principale source de rage pour les cas était principalement les morsures de chiens. Le statut vaccinal de tous les animaux n'a pas pu être déterminé. La majorité (80%) des patients n'ont pris ni vaccin antirabique ni immunoglobuline en prophylaxie post-exposition après la morsure de chien. Le délai médian d'admission avant le décès (plage interquartile) était de 2 jours (2 jours). La majorité (82%) des cas étaient atteints de rage furieuse. CONCLUSION: L'attention devrait être dirigée vers la vaccination de masse des chiens car les morsures de chien sont courantes. Assurer la disponibilité et l'accès à la prophylaxie post-exposition (PPE) est également crucial pour éviter les décès liés à la rage. MOTS-CLÉS: Rage, morsure de chien, post-exposition, prophylaxie, vaccination de masse.

Medical and legal evaluation of injuries due to dog bites: a Türkiye study.

BACKGROUND: Dog bites are the most common type of injury related to animal bites in our country and worldwide. Dog bite wounds pose significant public health concerns and have medicolegal implications. In this study, we aimed to assess the problems associated with dog bites and propose potential solutions. METHODS: We conducted a retrospective analysis of 149 cases submitted by judicial authorities to our institution, the Istanbul Council of Forensic Medicine, between 2015 and 2021, to obtain medicolegal expert opinion reports. Information regarding the cases included in the study was obtained from our archives and the National Judicial Network Project (UYAP) system. Data were recorded using Microsoft Excel 2016, and statistical analysis was performed using SPSS 25.0 for Windows (SPSS Inc., Chicago, IL). RESULTS: The mean age of the cases was 33.7 years, with 57% being male. 56.4% of the incidents occurred in the city center, and 30.9% took place during the summer months. 65.8% (n=98) of the cases were attributed to stray dogs. Superficial injuries without muscle tissue involvement were observed in 54.4% (n=81) of all cases, while 22.8% (n=34) had deep tissue defects or flap injuries, 4.7% (n=7) involved vascularnerve injuries, 16.1% (n=24) included bone fractures, and 2% (n=3) featured visceral injuries. Surgical treatment was performed on 37.5% (n=56) of the cases. Impairments were reported in 22.1% of the cases, with permanent facial scars affecting 16.7% of them. Psychiatric evaluations were required for 48.9% (n=89) of the cases, and 57.5% of them received a diagnosis of post-traumatic stress disorder. CONCLUSION: People attacked by dogs may experience serious physical or psychological sequelae. Therefore, it is crucial to evaluate all victims using a multidisciplinary approach, addressing their physical, social, and psychological needs, and providing rehabilitation when necessary. Non-governmental organizations, such as those dedicated to the prevention of cruelty to animals, in collaboration with local veterinary services, should play a role in national initiatives to provide objective and humane solutions for both victims and animals.

Shifts in the incidence of shark bites and efficacy of beach-focussed mitigation in Australia.

Shark-human interactions are some of the most pervasive human-wildlife conflicts, and their frequencies are increasing globally. New South Wales (Australia) was the first to implement a broad-scale program of shark-bite mitigation in 1937 using shark nets, which expanded in the late 2010s to include non-lethal measures. Using 196 unprovoked shark-human interactions recorded in New South Wales since 1900, we show that bites shifted from being predominantly on swimmers to 79 % on surfers by the 1980s and increased 2-4-fold. We could not detect differences in the interaction rate at netted versus non-netted beaches since the 2000s, partly because of low incidence and high variance. Although shark-human interactions continued to occur at beaches with tagged-shark listening stations, there were no interactions while SMART drumlines and/or drones were deployed. Our effect-size analyses show that a small increase in the difference between mitigated and non-mitigated beaches could indicate reductions in shark-human interactions. Area-based protection alone is insufficient to reduce shark-human interactions, so we propose a new, globally transferable approach to minimise risk of shark bite more effectively.

Management of Human Bites in a Rural Kenyan Setting: A Plastic Surgeon's 8-Year Experience.

INTRODUCTION: The treatment of human bites is a common issue facing healthcare practitioners in the developing countries of Sub-Saharan Africa where it has been noted as a growing public health concern. Generally, the desired outcomes from surgical management are healing, function, and aesthetics. We share our 8-year experience at Kapsowar Hospital in Kenya with the presentation, management, and outcome of human bites. We are uniquely situated to do so given the prevalence of human biting in our community and the full-time presence of a plastic surgeon at our institution. To the best of our knowledge, this study is the first to present human bite surgical management by a plastic surgeon certified by the American Board of Surgery working full-time on the African continent. METHODS: A retrospective chart review was conducted on all patients who presented to the operating theater at Kapsowar Hospital with a human bite between 2013-2021. After identification of eligible patients, charts were reviewed assessing parameters including age, gender, timing from injury to presentation at hospital, localization of bite, severity of facial wounds using Lackmann's classification, surgical procedure(s), postoperative complications, surgical revisions, antibiotics administered, and circumstance of incident. Data were analyzed using SPSS 29.0.0.0. RESULTS: Forty-four patients were identified. Seventeen (38.6%) were female and 27 (61.4%) were male. Thirty-one patients had facial bites and 13 patients had bites to other parts of the body. Of facial bites, 70.3% resulted in amputation of the affected part while 29.7% were lacerations. Using Lackmann's classification for facial bite severity, IIIA bites (complete avulsion) were most common for both males (9) and females (7). Females comprised 68.4% of total lip bite victims. Bites to the extremity were associated with late presentation and infection. We report a salvage rate of 85.7% for infected digits. CONCLUSIONS: Compared with most other studies on human bites, our patient population presents with a higher rate of avulsive lip injuries, most commonly among women. Our postoperative infection rate is lower than many others reported in the literature. Satisfactory cosmetic outcome with low risk of infection can be achieved by following well-established principles of wound healing and tension-free closure.

An increase in animal-related occupational injuries at a veterinary medical center (2008-2022).

OBJECTIVE: To characterize animal-related injuries in veterinary medical center staff at a veterinary medical center. SAMPLE: 706 hospital staff injuries. METHODS: Deidentified injury reports were submitted to Human Resources from 2008 through 2022. Injury data collected included the injury description, date of injury, occupation, and worker's compensation claim information. Data were summarized by year, cause of injury, total cost associated with injury, and occupation. RESULTS: There was an increase in injuries reported in recent years when compared to past years, with the plurality of injuries being bite injuries, specifically occurring on the hand, finger, and wrist area. Bite injuries had a higher average total worker's compensation cost paid to staff than striking injuries. There were more injuries reported by staff who had less experience working with animals. More injuries occurred during the summer months (June through September). There was not an unusual trend in the reporting of injuries due to COVID-19. Other injuries (eg, needlesticks and falls) were reported from only 2019 to 2022, but constituted a substantial burden for staff. CLINICAL RELEVANCE: These findings can help stakeholders at teaching hospitals and veterinary clinics to take steps toward creating a safer workplace environment for employees. It is important to identify work hazards and provide proper training and prevention methods to reduce the risk of injuries, especially among less experienced employees. Proper prevention methods will help reduce worker's compensation costs for the teaching hospital and reduce the number of workdays missed by staff.

Prospects for dog rabies elimination in Nigeria by 2030.

The attainment of the global target of zero dog-mediated human rabies by 2030 depends on functional rabies programmes. Nigeria, a rabies-endemic country, and the most populous country in Africa has a very poor rabies control strategy with a score of 1.5 out of 5 based on the Stepwise Approach towards Rabies Elimination (SARE). In this article, we report a scoping review that we conducted to highlight the strengths, weaknesses, opportunities and threats as well as situational analysis of rabies control in Nigeria and suggest a timeline for key activities that are needed to ensure zero by 30. Our findings reveal that rabies is grossly under-reported as only 998 human and 273 dog-suspected rabies cases were reported across Nigeria between 2017 and 2022. Our literature review also demonstrates a paucity of information on rabies in both human and animal health sectors. A total of 49 studies on dog rabies in Nigeria, with a predominance of reports from the North Central geopolitical region (48%, n = 23) were therefore included in this study. Currently, only 16.2% (n = 6/37) of Nigerian states have available data related to the estimated dog populations, the dog ownership rates, the vaccination status of dogs or the incidence of dog bites. Based on a dog-to-human ratio of 1:16.3, we estimated that the dog population in Nigeria was 12,969,368 (95% CI: 12,320,900-13,617,836). Thus, to attain herd immunity and dog rabies control in Nigeria, at least 9.1 million dogs must be vaccinated annually. Our review reveals that, despite the strengths and available opportunities to achieve rabies control in Nigeria by 2030, the weaknesses and challenges will make the attainment of zero by 30 very difficult or impossible. Nigeria's best-case scenario by the year 2030 is SARE stage 3-4 (control-elimination) out of 5. Otherwise, the rabies control programme might not surpass SARE stages 2-3. To attain zero by 30, Nigeria must re-strategize its current rabies control programme by funding and implementing the national strategic plan for rabies control, creating a rabies desk office in the 37 states (FCT inclusive), rigorously conducting mass vaccination campaigns, providing post-exposure prophylaxis, prioritizing mass enlightenment with a focus on responsible pet ownership and conduct baseline national rabies surveillance in the animal and human health sectors.

Facial dog bites in children: A public health problem highlighted by COVID-19 lockdown.

BACKGROUND: Stay-at-home injunction during COVID-19 pandemic led to new dynamics in households and increased the risk of domestic accidents involving pets. The aim of the study was to demonstrate an increase of facial dog bites in children during first lockdown period in France, compared to the same period in 2018 and 2019. Secondary objective was to investigate the demographics and circumstances in which dog bites occurred. METHODS: A retrospective multicentric study was conducted nationwide. Patients under 18 years old managed in fifteen oral and maxillofacial surgery departments for a dog bite were included. RESULTS: Eighty-seven patients were included. A significant increase of the number of children managed for facial dog bite was noticed in 2020 (p=0.0005). The male-to-female ratio was significantly reversed in 2020 with more bites in girls than boys (p=0.02). In 2020, children were mostly bitten to cheeks (28.6 %), lips-and-chin region (26.2 %), and eyelids (23.8 %). Severe bites increased in 2020, in comparison with 2018 and 2019. Dog bites occurring while petting or playing significantly increased in 2020 (31 %) (p=0.03). CONCLUSION: The process leading to bites is highly dependent on the balance of dog-owner relationship. This was strongly disrupted during COVID-19 pandemic, resulting in the increase of dog bites in households. Regarding dog bites, face is the most vulnerable area in children. Its injury has lots of esthetic and functional consequences and maxillofacial surgeons have a key role to play in their prevention. Reminders of some of these management and prevention strategies are presented in this article.

High risk of bat bites in an indigenous village in Brazil: Warning of the re-emergence of rabies among the Maxakali People.

Bat-mediated human rabies is a viral zoonotic disease that poses a serious threat to the public health of traditional peoples, especially indigenous populations that maintain primitive cultural and social habits, such as the Maxakali ethnic group, located in the southeastern region of Brazil. The sociocultural habit of this population led to the emergence between April and May 2022 of the viral spillover of rabies transmitted by bats, which decimated the lives of four children from this population who maintained contact with this animal as a recreational practice. Because the vampire bats Desmodus rotundus have exceptional ecology and social characteristics that can have important effects on the dynamics of viral dispersion in this indigenous population, I present the dynamics of contact between native children and the bat and the meaning of this relationship, which involves ritualistic and recreational significance. As important as knowing the reasons for this practice is discussing some intrinsic and extrinsic factors that imply risks that intensify the vulnerability of this population to the transmission of the rabies virus at any time. In view of this, I warn of the need to adopt efficient strategies to mitigate the risks of a new emergency in this region. Although emergency containment measures were carried out during the critical period of the outbreak, such animal and environmental control actions must become routine programmatic and structuring interventions. Essential for rabies surveillance in this population is to develop culturally adapted interethnic health education campaigns to guarantee the accessibility of the Maxakali indigenous people to the content taught, so that any attempt at domestication, captivity and recreational practices with bats of any species is discouraged, thus avoiding a possible re-emergence of this anthropozoonosis that has impacted not only the epidemiological scenario in this region, but throughout Brazil, and also throughout Latin America.

Observamos 3 casos de mortalidad por rabia humana y 1 por shock hipovolémico. Conclusión. Las lesiones producidas por perros son causas frecuentes de visita a emergencia y hospitalización en pediatría, y tienen características particulares en niños de hasta 5 años de edad.

Introduction. The objective of this study is to describe the characteristics of dog bite injuries in children seen at a children's hospital in Bolivia. Population and methods. This was an observational, retrospective study in patients seen between 2017 and 2021. Results. A total of 769 patients were studied. Dog bite injuries accounted for 5.6% of emergency visits and 0.8% of hospitalizations. They were more frequent in children younger than 5 years (55.1%), in whom the following were observed: greater injury severity (p = 0.008), history of animal provocation (p = 0.048), known attacking animal (p < 0.036), domestic accident (p = 0.021), greater frequency of post-exposure prophylaxis with anti-rabies serum (p = 0.005), and maxillofacial area as the main region involved (p < 0.001). There were 3 deaths due to human rabies and 1 due to hypovolemic shock. Conclusion. Dog bite injuries are a frequent cause of visit to the emergency department and hospitalization in pediatrics and have specific characteristics in children younger than 5 years.

Measuring the impact of an integrated bite case management program on the detection of canine rabies cases in Vietnam.

Introduction: Dog-mediated rabies is enzootic in Vietnam, resulting in at least 70 reported human deaths and 500,000 human rabies exposures annually. In 2016, an integrated bite cases management (IBCM) based surveillance program was developed to improve knowledge of the dog-mediated rabies burden in Phu Tho Province of Vietnam. Methods: The Vietnam Animal Rabies Surveillance Program (VARSP) was established in four stages: (1) Laboratory development, (2) Training of community One Health workers, (3) Paper-based-reporting (VARSP 1.0), and (4) Electronic case reporting (VARSP 2.0). Investigation and diagnostic data collected from March 2016 to December 2019 were compared with historical records of animal rabies cases dating back to January 2012. A risk analysis was conducted to evaluate the probability of a rabies exposure resulting in death after a dog bite, based on data collected over the course of an IBCM investigation. Results: Prior to the implementation of VARSP, between 2012 and 2015, there was an average of one rabies investigation per year, resulting in two confirmed and two probable animal rabies cases. During the 46 months that VARSP was operational (2016 - 2019), 1048 animal investigations were conducted, which identified 79 (8%) laboratory-confirmed rabies cases and 233 (22%) clinically-confirmed(probable) cases. VARSP produced a 78-fold increase in annual animal rabies case detection (one cases detected per year pre-VARSP vs 78 cases per year under VARSP). The risk of succumbing to rabies for bite victims of apparently healthy dogs available for home quarantine, was three deaths for every 10,000 untreated exposures. Discussion: A pilot IBCM model used in Phu Tho Province showed promising results for improving rabies surveillance, with a 26-fold increase in annual case detection after implementation of a One Health model. The risk for a person bitten by an apparently healthy dog to develop rabies in the absence of rabies PEP was very low, which supports the WHO recommendations to delay PEP for this category of bite victims, when trained animal assessors are available and routinely communicate with the medical sector. Recent adoption of an electronic IBCM system is likely to expedite adoption of VARSP 2.0 to other Provinces and improve accuracy of field decisions and data collection.

Exploring the spatial pattern of animal bites in Iran (2021-2022).

OBJECTIVE: Knowledge of the spatial pattern of animal bites can be helpful for targeted resource allocation and to develop and deliver effective intervention programs. The aim of this study was to explore the spatial pattern of the animal bites in Iran during 2021-2022. METHODS: Animal bite cases from all provinces and counties in Iran were obtained from a nationally based registry. Global Moran's I was applied to check spatial autocorrelation. The spatially adjusted standardized incidence ratios (SIRs) were estimated using the Besag, York, and Mollie (BYM) model. Spatial clusters were identified by local indicators of spatial association (LISA) and purely spatial scan statistic. RESULTS: A total of 260,470 animal bites were registered during the study period. There was a positive spatial autocorrelation (global Moran's I=0.27, p-value=0.001). The majority of SIRs greater than 1.00 was found in counties in the northern belt of Iran (e.g., observed greater than expected animal bites). LISA found that approximately 7% of counties in the north and northeast, 18% in the west and south, and 3% in the central part of Iran were significant hot spots, cold spots, and spatial outliers (p-value≤0.05). Spatial scan statistic detected primary hot spot cluster in the counties in the Mazandaran and Alborz provinces (Relative Risk=2.56, p-value<0.001), while primary cold spot cluster involved counties in Kurdistan and Kermanshah province (0.37, <0.001). CONCLUSION: Animal bites were unevenly distributed in Iran. Further prevention and control programs as well as appropriately resource allocation are needed in order to reduce the observed animal bites spatial disparity.

Epidemiological pattern and management of dog bite injuries in Karachi, Pakistan: A cross-sectional study.

BACKGROUND: Dog bite injuries are a common problem globally; however, little is known about the epidemiology of dog bite injury from a low-and-middle-income country like Pakistan. This study aims to determine the epidemiology of dog bite injuries among children and adults from a tertiary care hospital in Karachi, Pakistan. METHODS: We conducted a cross-sectional study on dog bite patients visiting the emergency department from November 2015 to August 2016 of a major public tertiary care hospital. Data was collected using a structured questionnaire on demographic details, bite history, and management of dog bite victims. Descriptive analysis was reported. Chi-square test was applied to check the associations between age-specific dog bite cases and independent variables. RESULTS: 2178 participants were included in the analysis. 715 (38.8%) were children less than 18 years old, and 1463 (61.2%) were adults over 18 years. A majority of the patients were males (1909, 87.7%). Results show that most dog bite injuries (2052, 94.2%) tend to occur outside the house by stray dogs biting without provocation. People aged 18 years and above (61.2%) and males (children: 84.6%, adults: 89.1%) tend to be bitten more often. Lower limbs are most frequently bitten (children: 69.5%, adults: 85.8%). Free-roaming stray dogs (children: 73.4%, adults: 74.9%) were involved in reported biting cases. Many of the patients did not receive appropriate first aid and instead just washed the wound with soap and water (children: 45.1%, adults: 43.7%). 99% of the victims received Tetanus toxoid, Rabies vaccine, and immunoglobulins while in the emergency department. CONCLUSION: There is a high burden of dog bite injuries from stray dogs in Karachi, Pakistan. Efforts should be made to create awareness among the general public on the risks of dog bites and on seeking appropriate first aid and medical attention for a dog bite injury.

Epidemiologic Aspects of Animal Bite, Rabies, and Predictors of Delay in Post-exposure Prophylaxis: A National Registry-based Study in Iran.

BACKGROUND: The increasing trend in animal bites and rabies in recent years makes the disease a public health concern in Iran. The objectives of the current study were to investigate the epidemiologic aspects of the animal bite and determine the associated risk factors of the delay in initiation of post-exposure prophylaxis (PEP) against rabies in Iran. STUDY DESIGN: National registry-based cross-sectional study. METHODS: This study included all registered cases of animal bites between March 2021 and March 2022 at the Ministry of Health and Medical Education in Iran. We retrieved epidemiologic data on person, time, place, and PEP outcome. RESULTS: A total of 260470 animal bite cases (approximately 334 per 100000 populations, and 11 deaths) were registered during the study period. About 77.2% of them were reported in males, 4.3% in children aged less than 5 years, 56.4% occurred in urban areas, 98% in domestic animals, and mostly in north and northeast areas of Iran. Additionally, 2.8% of cases had a delay of more than 48 hours in the initiation of PEP. Significant determinants of the increase in delay were female gender (OR=1.43, 95% CI: 1.36, 1.51, P<0.001), foreign nationality (OR=1.19, 95% CI: 1.01, 1.12, P=0.001), rural residence (OR=1.07, 95% CI: 1.01, 1.12, P=0.010), and the wild animals (OR=1.22, 95% CI: 1.12, 1.34, P<0.001). CONCLUSION: The observed frequency of animal bites in a year indicates a serious public health concern and the need for targeted interventions, especially in at-risk areas and vulnerable populations.

Presentation and treatment of animal and human bite injuries at a Swiss tertiary emergency department: a cross-sectional study.

BACKGROUND: Animal and human bite injuries are a relevant health problem worldwide. With the increasing number of pets, bite injuries are becoming more frequent. Previous studies on animal and human bite injuries in Switzerland were completed several years ago. The aim of the present study was to provide a detailed overview of patients with bite injuries admitted to a tertiary emergency department in Switzerland in terms of demographics, injury patterns and treatment strategies. METHODS: A 9-year cross-sectional analysis of patients presenting to the emergency department of Bern University Hospital in the period January 2013 to December 2021 following an animal or human bite injury. RESULTS: A total of 829 patients with bite injuries were identified, including 70 for postexposure prophylaxis only. Their median age was 39 (IQR 27-54) years and 53.6% were female. Most patients were bitten by a dog (44.3%), followed by cats (31.5%) and humans (15.2%). Most bite injuries were mild (80.2%); severe injuries were mainly found in dog bites (28.3%). Most patients were treated within six hours after human (80.9%) or dog (61.6%) bites; after cat bites, patients often presented with a delay (74.5%) and signs of infection (73.6%). Human bite wounds were superficial in the majority of cases (95.7%), rarely showed signs of infection (5.2%) at the time of presentation and hospitalisation was never required. CONCLUSIONS: Our study provides a detailed overview of patients admitted to an emergency department of a tertiary Swiss University Hospital after an animal or human bite. In summary, bite injuries are common among patients who present to the emergency department. Therefore, primary and emergency care clinicians should be familiar with these injuries and their treatment strategies. The high risk of infection, particularly in cat bites, may warrant surgical debridement in the initial treatment of these patients. Prophylactic antibiotic therapy and close follow-up examinations are recommended in most cases.
