Objective: Pet ownership among people experiencing homelessness (PEH) is common, but access to shelter, veterinary care, and flea-preventative products for PEH who own pets in the US is not well described. We sought to evaluate current knowledge of fleas and flea-borne diseases and characterize practices around pets and service animals among staff at homeless shelters and outreach organizations.

Methods: In-person surveys were administered to staff at homeless shelters and on outreach teams in 7 states from August 2022 to April 2023 to evaluate knowledge, attitudes, and practices and to assess homeless shelter/organizational characteristics.

On September 28, 2023, a kitten aged approximately 6 weeks found in Omaha, Nebraska, had test results positive for rabies at the Nebraska Veterinary Diagnostic Center (NVDC) after dying with neurologic signs and having bitten and scratched its caretakers. Preliminary investigation identified 10 exposed persons for whom postexposure prophylaxis (PEP) was recommended. Subsequent variant-typing by NVDC yielded a presumptive positive result for the Eastern raccoon rabies virus variant (RRVV), which CDC confirmed on October 6.

Article Synopsis
  • Louse-borne Bartonella quintana and flea-borne murine typhus are serious diseases affecting people experiencing homelessness in the US, but service staff's awareness and prevention knowledge is limited.
  • A survey of 333 staff from 89 shelters across seven states revealed that while most recognize the problem of body lice and fleas, only about half understand their disease transmission potential, and less than 25% can describe proper management protocols.
  • There are significant gaps in understanding among staff regarding these diseases, highlighting the need for training to improve prevention efforts and ensure equitable service access for affected individuals.

Article Synopsis
  • * An investigation revealed a cluster of COVID-19 symptoms among farm employees coinciding with increased illness and death rates in mink, with nearly all sampled mink testing positive for the virus.
  • * Genetic similarities between the virus in mink and infected workers suggest that humans contracted COVID-19 from the mink, prompting the need for comprehensive public health strategies to control zoonotic virus transmission.

Fleaborne typhus (also known as murine typhus), a widely distributed vectorborne zoonosis caused by Rickettsia typhi, is a moderately severe, but infrequently fatal illness; among patients who receive doxycycline, the case-fatality rate is <1%. Fleaborne typhus is a mandated reportable condition in California. Reported fleaborne typhus cases in Los Angeles County have been increasing since 2010, with the highest number (171) reported during 2022.

Alpha-gal syndrome (AGS) is an emerging, tick bite-associated immunoglobulin E-mediated allergic condition characterized by a reaction to the oligosaccharide galactose-alpha-1,3-galactose (alpha-gal), which is found in mammalian meat and products derived from mammals, including milk, other dairy products, and some pharmaceutical products. Symptoms range from mild (e.g.

Alpha-gal syndrome (AGS) is an emerging, tick bite-associated allergic condition characterized by a potentially life-threatening immunoglobulin E (IgE)-mediated hypersensitivity to galactose-alpha-1,3-galactose (alpha-gal), an oligosaccharide found in most nonprimate mammalian meat and products derived from these mammals. Specific symptoms and severity of AGS vary among persons, and no treatment or cure is currently available. During 2010-2018, more than 34,000 suspected cases of AGS were identified in the United States, but current knowledge of where cases occur is limited.

From July−November 2020, mink (Neogale vison) on 12 Utah farms experienced an increase in mortality rates due to confirmed SARS-CoV-2 infection. We conducted epidemiologic investigations on six farms to identify the source of virus introduction, track cross-species transmission, and assess viral evolution. Interviews were conducted and specimens were collected from persons living or working on participating farms and from multiple animal species.

Article Synopsis
  • The study aimed to understand how SARS-CoV-2 affects companion animals in the US, focusing on clinical and epidemiologic aspects from March 2020 to December 2021.
  • Involved 204 pets (109 cats and 95 dogs) across 33 states with confirmed COVID-19 infections, primarily after being exposed to infected humans.
  • Findings showed that most infections were linked to human exposure, with significant illness duration (15 days for cats, 12 for dogs) and a 10-day gap between human and pet illness onset, highlighting the importance of tracking both species in disease transmission studies.

Since May 2022, approximately 20,000 cases of monkeypox have been identified in the United States, part of a global outbreak occurring in approximately 90 countries and currently affecting primarily gay, bisexual, and other men who have sex with men (MSM) (1). Monkeypox virus (MPXV) spreads from person to person through close, prolonged contact; a small number of cases have occurred in populations who are not MSM (e.g.

Zoonotic diseases represent a heavy global burden, causing important economic losses, impacting animal health and production, and costing millions of human lives. The vaccination of animals and humans to prevent inter-species zoonotic disease transmission is an important intervention. However, efforts to develop and implement vaccine interventions to reduce zoonotic disease impacts are often limited to the veterinary and agricultural sectors and do not reflect the shared burden of disease.

Article Synopsis
  • - SARS-CoV-2 has been found in various species, including pets like dogs and cats, with dog illnesses typically resolving on their own without extensive diagnosis.
  • - As new variants of SARS-CoV-2 arise, the symptoms and transmission dynamics in animals can change, prompting a need for ongoing monitoring.
  • - The report focuses on two dogs infected with the Delta variant, showing different symptoms despite similar exposure to a vaccinated human, underlining the necessity for more research on the impact of these variants on pets and other animals.

Background And Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), besides causing human infection, has been shown to naturally infect several susceptible animal species including large cats (tigers, lions, pumas, spotted leopards), dogs, cats, ferrets, gorillas and minks. Cats and minks are continuing to be the most reported species with SARS-CoV-2 infections among animals but it needs to be investigated further.

Methods And Results: We report the detection of SARS-CoV-2 from a domestic cat that exhibited respiratory disease after being exposed to SARS-CoV-2 virus from humans in the same household.

Objective: To establish a pathoepidemiological model to evaluate the role of SARS-CoV-2 infection in the first 10 companion animals that died while infected with SARS-CoV-2 in the US.

Animals: 10 cats and dogs that tested positive for SARS-CoV-2 and died or were euthanized in the US between March 2020 and January 2021.

Procedures: A standardized algorithm was developed to direct case investigations, determine the necessity of certain diagnostic procedures, and evaluate the role, if any, that SARS-CoV-2 infection played in the animals' course of disease and death.

While other industries have effectively used simulation as an educational strategy to improve safety and performance, nurse educators have not yet embraced this as an educational tool for safety initiatives. This article examines the benefit of using simulation exercises as an adjunct to didactic teaching and describes how one hospital's nurse educators adapted simulation methodology to educate the nurses on the complexity of safe medication administration and the importance of critical thinking in daily practice.
