India's Stray Dogs as a Public Health Risk: An Autopsy Case Report and Comprehensive Review

INTRODUCTION

The fatal stray dog attack on a toddler in India serves as a reminder of the serious risks that dog bites and rabies represent to public health. A significant vector for the spread of rabies, stray dogs are responsible for thousands of cases that are recorded each year (1). Children under ten are especially susceptible to dog bites, which makes them a high-risk demographic in places where there are large numbers of stray dogs. According to the published reports, there are 17.9 dog bite cases for every 1000 children in this age bracket (2). The potential of serious repercussions is also increased by the fact that many dog bites happen without provocation and frequently take place in homes (3). Stress, hunger, or territorial tendencies can cause stray dogs to act aggressively, which can lead to bite injuries that cause serious trauma and infections that need medical attention (4). Furthermore, anxiety brought on by the fear of attacks can have a detrimental effect on a person's quality of life, especially in children and other vulnerable people. The severity of injuries and public health issues is brought to light in this case study, which is based on a tragic incident in which a stray dog attacked a 5-year-old boy. Extensive trauma, including deep cuts, exposed bone, and serious internal injuries, was discovered during the autopsy. This demonstrated the tragic consequences of such attacks and the pressing need for efficient stray dog population management. Serious public health issues are raised by the increasing number of stray dogs, which calls for quick action in the form of catching and housing stray dogs in shelters to minimize risks to the community, immunization campaigns, sterilization initiatives, public awareness campaigns, and infrastructural upgrades.

CASE PRESENTATION

A stray dog killed a 5-year-old boy who was playing outside his house. The boy had already passed away from his injuries, requiring a postmortem, so rescuers could only run the dog away to assess the situation. When the autopsy was performed 14 h after the death, it disclosed the body of a 5-year-old child who was normally developed, weighing 20 kg and standing 118 cm in length. Rigor mortis was moderately established across all joints. The examination identified severe injuries concentrated on the head, neck, and back. Deep lacerations were present, involving the trapezoid muscle, with portions of the occipital bone exposed. The back of the head was notably bald, displaying multiple linear excoriations and evidence of hair being forcibly pulled out (Images 1 and 2). The face exhibited extensive abrasions, bruised lips, and petechial hemorrhages on the conjunctival mucosa of the lower eyelids. A stretch laceration was present above the left eyebrow, while a similar wound was observed in the left parietal region above the ear. The nose was severely lacerated, and a deep, gaping wound beneath the chin exposed the perforated thyroid cartilage. There was no evidence of defensive actions. Internal examination revealed minimal findings, except for a small amount of blood in the airways. The neck dissection showed deep muscle lacerations, avulsion of the right lateral processes of cervical vertebrae C1 and C5, and three perforations in the larynx, two at the vocal cord level. A small transmural tear was noted in the right jugular vein, with no signs of air embolism. The brain was swollen but otherwise intact, and histological and toxicological tests provided no additional significant findings.

DISCUSSION

Stray dogs contribute significantly to rabies cases in India, causing over 25,000 deaths annually (5). Studies show that dogs account for 92% of animal bite incidents, with children comprising many of the victims (6). Dog bite injuries are common, affecting nearly 50% of children at some point in their lives (7). Fatal attacks on children have also been documented, often resulting in severe craniofacial trauma and, in extreme cases, even decapitation (8). Injuries from dog attacks are often severe, especially in young children, frequently necessitating extensive medical and surgical treatment (9). The head, neck, and extremities are most frequently affected by dog bites, which can result in severe damage such as deep lacerations and blunt force injuries (10). Deaths might be brought on by the direct effects of the wounds or by subsequent issues like sepsis brought on by infections (11). As per the available literature, children younger than 5 years old experience the most serious bites, and medium- to large-sized dogs that the victims are familiar with are frequently involved (12). The importance of bite mark analysis in identifying canine assaults is highlighted by forensic veterinary medicine. Dog participation is frequently indicated by bite marks with symmetrical wounds and angular borders. These unique patterns provide vital evidence in forensic investigations by helping to distinguish injuries from different animals (13). The fact that these bites frequently take place in familiar or home environments emphasizes the need for increased awareness, preventative actions, and post-exposure prophylactic access. In order to reduce the serious consequences of rabies and death, the concerning data highlight the urgent need for extensive vaccination campaigns, efficient stray dog management programs, and public education.

During an autopsy in dog bite fatalities, injuries and possible reasons of death from canine bites are thoroughly examined. Understanding the methods of injury, examining the features of bite marks, and determining any infections or complications that might have played a role in the victim's demise all depend on these autopsies. Determining the timing and type of injuries can be difficult with autopsies, especially when separating premortem from postmortem animal behavior (11). Underlying medical issues can sometimes make it difficult to interpret injuries, necessitating a multidisciplinary approach to determine the cause of death and the extent of animal attacks (10). Autopsies for dog bites provide important information about the circumstances surrounding deaths, but they also highlight the difficulties in conducting forensic examinations, particularly when separating animal injuries from other possible causes of death. Cases of stray dogs biting kids highlight serious public health concerns and the pressing need for efficient management techniques. As seen in Karnataka, India, severe measures such as the mass extermination of stray dogs have been put in place in reaction to dog attacks (14). Nonetheless, public health officials have come under fire for their inadequate preventive measures in spite of the high frequency of dog bites. Concerns regarding animal welfare and public health safety have been highlighted by the absence of effective methods to address the underlying cause of these attacks (9).

The problem is complicated and affects communities through environmental pollution, physical assaults, and the spread of illness. Through bites, urine, and contaminated settings, stray dogs pose serious health threats to humans by spreading zoonotic illnesses like rabies, leptospirosis, and parasites (15). Stress, hunger, or territorial tendencies can cause stray dogs to act aggressively, which can lead to serious bite wounds and infections. Furthermore, anxiety can be brought on by the fear of attacks, particularly in young people and those who are more susceptible. Because they scavenge through trash, leave litter, and create unhygienic circumstances, stray dogs contribute to environmental and hygiene issues. In public areas, their excrement can introduce dangerous microorganisms into the soil and water. Significant medical expenses for treating bites, managing rabies, and containing disease outbreaks are part of the financial burden of stray dogs. Furthermore, significant resources are needed to manage stray populations through immunization and sterilization programs (16). Issues with stray dog management include overcrowding brought on by poor sterilization and ignorance. Attempts to solve the problem are further complicated by the fact that many areas lack efficient structures and policies. Inadequate vaccination procedures and a lack of knowledge contribute to the high frequency of dog bites, particularly among children (4). Children are put at danger because many veterinarians wait until 3 months to administer vaccines. Improved vaccine scheduling, community education on preventing dog bites, and prompt medical attention are all urgent public health priorities (6). Significant public health issues are raised by the expanding number of stray dogs, which calls for quick action and concerted measures to successfully manage the problem. Capturing and rehabilitating stray dogs in properly managed shelters may serve as an important public health and safety intervention. Such measures can help reduce the incidence of dog attacks, transmission of zoonotic diseases, and other community-related risks associated with uncontrolled stray dog populations. Shelter-based management allows for systematic vaccination, sterilization, medical care, and rehabilitation of stray animals in a humane manner. Public education initiatives to increase knowledge of ethical pet ownership and the dangers of dog bites, sterilization programs to limit overcrowding, and broad vaccination to avoid zoonotic diseases like rabies are important tactics. Additionally, by reducing the amount of food sources available to stray dogs, infrastructure upgrades like improved waste management systems can deter them from congregating in metropolitan areas. Autopsies involving dog bite injuries are essential to comprehending the causes of injuries and the circumstances surrounding mortality. They offer important forensic information about animal assaults, including the type of bite marks and the degree of trauma. These studies also draw attention to how difficult it can be to differentiate between animal injuries and other possible causes of mortality. For the safety and well-being of both people and animals, addressing these issues calls for a multidisciplinary strategy that incorporates forensic knowledge, veterinary treatment, and public health.

CONCLUSION

Significant public health issues are raised by the growing number of stray dogs, necessitating immediate intervention in the form of immunization, sterilization, education, and better infrastructure. Autopsies for dog bites reveal important details, but they also show how difficult it is to differentiate injuries caused by animals from other causes of death.
