Topic:Public Health
The topic of Public Health and horses encompasses the study of interactions between equine populations and human health systems. It involves examining the transmission of zoonotic diseases, which are diseases that can be transferred between animals and humans, as well as the role of horses in the epidemiology of such diseases. This field also considers the impact of equine-related activities on public health, including injuries and environmental effects. Research in this area often explores preventive measures, management strategies, and policies to mitigate health risks associated with horses. This page compiles peer-reviewed research studies and scholarly articles that investigate the intersection of equine and public health, focusing on disease transmission, risk assessment, and health management strategies.
Perceptions of Whether Stereotypic Off-the-Track Thoroughbreds are Harder to Rehome Than Nonstereotypic OTTBs-A Pilot Survey Study. Several studies have indicated higher incidence of stereotypic behaviors (STBs) in Thoroughbreds. The aftercare of Off-the-Track Thoroughbreds (OTTBs) has received increased attention in the last decade; however, research on the impact of STBs on placement of OTTBs after their racing career is limited. Thoroughbred Aftercare Alliance (TAA) accredits centers throughout North America that work to rehome OTTBs in a safe, welfare-friendly manner. Although the authors have suspected that having an STB would make OTTBs more challenging to rehome, this hypothesis remains to be empirically tested. The...

It is endemic in India, with an estimated annual 20,000 human deaths (one-third of the global rabies burden). The magnitude of animal rabies incidence is unknown. In four sub-districts of Punjab, India, we monitored canine and livestock populations from August 15, 2016 to August 14, 2017. Demographic, clinical and rabies diagnostic laboratory (RDL) data were collected from suspected cases of rabies. The annual incidence rate / 10,000 animal years at risk (95% CI) in each sub-district was estimated for each ...
[Ethics in Swiss equestrian sports: Is animal welfare adequately implemented?]. Animal welfare in equestrian sports is a very current and important topic for animal right groups as well as for the Swiss association for equestrian sports "Schweizerischer Verband für Pferdesport (SVPS)". The penalty commission "Sanktionskomission (SAKO)" of the SVPS reported only few to none cases of infringements of animal welfare provision on horses at a time in the past few years. This fact was criticised several times by different animal right groups in Switzerland. Therefore a survey was sent in 2017 to 544 active officials (horse show judges) of the SVPS. Overall, 146 answered questi...

[Equestrian related injuries and pathologies]. Equestrian sports are widely practiced in Switzerland as hobbies. Horses are imposing and unpredictable. As a result, traumatisms associated with horseback riding are common and cause serious injuries. Cranial traumatisms are among the most frequently encountered injuries and are associated with high rates of hospitalization and mortality. Helmet use decreases the severity of intracranial lesions. Close contact with horses can lead to the development of infectious diseases and respiratory allergies. Although infrequent in Europe, these infections occur sporadically and should be known by gener...
Systematic analysis to assess the scientific validity of the international residue limits for caffeine and theophylline in horse-racing. Based on their performance-enhancing potential, caffeine and theophylline are prohibited substances in equine sports. Residues in horses can be caused by wilful application or by unintended uptake of contaminated feed. The International Federation of Horseracing Authorities recently introduced international residue limits (IRLs) to facilitate the discrimination between pharmacological relevant and irrelevant concentrations in doping samples. The objective of this study was to investigate the scientific validity of these IRLs. A systematic analysis was performed to assess the IRLs by different ...

Equine viral encephalitis: prevalence, impact, and management strategies. Members of several different virus families cause equine viral encephalitis, the majority of which are arthropod-borne viruses (arboviruses) with zoonotic potential. The clinical signs caused are rarely pathognomonic; therefore, a clinical diagnosis is usually presumptive according to the geographical region. However, recent decades have seen expansion of the geographical range and emergence in new regions of numerous viral diseases. In this context, this review presents an overview of the prevalence and distribution of the main viral causes of equine encephalitis and discusses their impact an...
Molecular characterization of equine infectious anaemia virus strains detected in England in 2010 and 2012. Equine infectious anaemia virus (EIAV) is a retrovirus with worldwide distribution which is notifiable to the OIE. Despite its importance to the equine industry, most information regarding its biology have been obtained using only two strains (EIAV and EIAV ) from the USA and China, respectively. Recently full genome sequences from Ireland, Italy and Japan have been published; however, this is still not representative of the number of EIAV outbreaks experienced globally each year. The limited availability of published sequences makes design of a universal EIAV PCR difficult, hence diagnosis is...
