Abstract

OBJECTIVE:To describe the clinical and epidemiologic features of persons with dog and cat bite injuries who presented to emergency departments.

SAMPLE:Records of 648,492 dog and cat bite-related emergency department visits in California from 2005 to 2019.

PROCEDURES:Visits were selected by standardized International Classification of Diseases, Ninth or Tenth Revision, Clinical Modification codes that indicated a bite as an external cause of injury in the medical record. Incidence rates were calculated for patient demographics, location and month of bite incident, characteristics of bite injury, infection, patient outcome/disposition, and expected source of payment. Cross-sectional descriptive analysis was performed.

RESULTS:The average annual incidence of dog bites was highest in children aged < 10 years and males, while that of cat bites was highest in adults aged ≥ 80 years and females. Bites were more likely to occur in rural settings, in private residences, and during the summer. The median household income for zip codes in which animal bite patients resided was lower than the statewide median household income. Both dog and cat bite injuries were more likely to occur to upper limbs. Bacteria were isolated from 3% of dog bite injuries and 21.5% of cat bite injuries at initial presentation.

CLINICAL RELEVANCE:Epidemiologic findings about persons presenting to emergency departments for animal bite injuries can inform bite prevention efforts by identifying at-risk populations. Effective animal bite prevention demands an ongoing multisectoral program of veterinarians and other health professionals, collaborating with community and governmental organizations, to develop and implement integrated strategies within the context of other socially contributory factors.

National survey reveals elastic price sensitivity for select equine veterinary services.
Willingness-to-pay questions were presented with a payment card approach and addressed 3 common services: annual spring vaccinations, lameness examinations, and emergency colic surgeries. In a payment card approach, respondents choose from among preselected values. Respondents were asked to choose the maximum amount they would be willing to pay for each service.

Canine distemper outbreak and laryngeal paralysis in captive tigers (Panthera tigris).
All suspected and confirmed cases of CDV infections were significantly associated with laryngeal inflammation, which developed into paralysis in almost 50% of cases. Altogether, 50% of all tiger cases with chronic infection developed stridor at 314 days after virus infection. Therefore, laryngeal paralysis may result from CDV infection and degeneration, potentially affecting the peripheral and central nervous systems. This condition could pose a life-threatening risk to tigers.

Investigating the relationship between canine training classes and post-adoption return rates in North American shelters
Of all the returned dogs, those who attended training were more likely to be returned for owner-related reasons (58.8?%), whereas dogs who did not attend training were more likely to be returned for animal-related reasons (78.9?%). While attending training classes at animal shelters may help to reduce behavioral returns, as shown by the shift in return reasons, they do not appear to reduce return rates significantly for the general shelter population.

Companion animal veterinary personnel have occupational risk for tularemia and One Health role for tularemia prevention in Kansas.
Forty-three percent (47 of 109) of veterinarians reported diagnosing tularemia in cats and 13% (14 of 109) in dogs. Seven percent (8 of 109) of veterinarians reported having had tularemia. When performing procedures with a high risk of exposure, such as lancing abscesses in tularemia suspects, glove use was 100% but additional personal protective equipment was inconsistent, including eye protection (70%) and surgical face mask (59%).
