Study indicates interspecies transmission of SARS-CoV-2 between humans and their pets occurs regularly VirusesMDPI Loeffler_News covid COVID19 SARSCoV2 zoonotic disease immunology news pet dogs interspecies
By Pooja Toshniwal PahariaApr 3 2023Reviewed by Lily Ramsey, LLM In a recent study published in the Viruses Journal, researchers assessed severe acute respiratory syndrome coronavirus 2 seroprevalence among domestic dogs and cats in households with SARS-CoV-2-positive humans in Germany.
About the study In the present study, researchers evaluated COVID-19 prevalence among cats and dogs in German households with SARS-CoV-2-positive household contacts. They also analyzed risk factors for SARS-CoV-2 transmission between humans and animals and COVID-19 symptomatology in domestic animals.
The serological findings were analyzed with data obtained via questionnaires filled out by the pet owners. Multivariate logistic regression modeling was performed for the analysis, and the odds ratios were calculated. Contrastingly, for dogs, contact beyond the household increased the risk of infection and lowered contact after established human infection, significantly protecting against COVID-19. No statistically significant associations existed between the documented COVID-19 symptomatology in the pets and their serological status.
Cats with SARS-CoV-2 seropositivity had a significantly greater likelihood of having more than average intensity of contact with owners . Dogs showed a significantly lower likelihood of turning seropositive when owners reduce contact with them in the quarantine period .

Australian study finds Mediterranean diet meets nutrient requirements and cheaper than traditional Western dietsA recent study by researchers at the University of South Australia has indicated that the majority of Australians are not eating a balanced healthy diet as recommended by the Australian Dietary Guidelines (ADG) and Australian Guide to Healthy Eating (AGHE). A proper diet is essential because it can alleviate the risks of developing chronic diseases like type two diabetes, osteoporosis, heart disease, and obesity.

Mobile health to promote physical activity in people post stroke or transient ischemic attack – study protocol for a feasibility randomised controlled trial - BMC NeurologyBackground Physical activity is essential to improve health and reduce the risk of recurrence of stroke or transient ischemic attack (TIA). Still, people post stroke or TIA are often physically inactive and the availability of physical activity promotion services are often limited. This study builds on an existing Australian telehealth-delivered programme (i-REBOUND– Let’s get moving) which provides support for home-based physical activity for people post stroke or TIA. The aim of this study is to test the feasibility, acceptability, and preliminary effects of a mobile Health (mHealth) version of the i-REBOUND programme for the promotion of physical activity in people post stroke or TIA living in Sweden. Methods One hundred and twenty participants with stroke or TIA will be recruited via advertisement. A parallel-group feasibility randomised controlled trial design with a 1:1 allocation ratio to 1) i-REBOUND programme receiving physical exercise and support for sustained engagement in physical activity through behavioural change techniques, or 2) behavioural change techniques for physical activity. Both interventions will proceed for six months and be delivered digitally through a mobile app. The feasibility outcomes (i.e., reach, adherence, safety and fidelity) will be monitored throughout the study. Acceptability will be assessed using the Telehealth Usability Questionnaire and further explored through qualitative interviews with a subset of both study participants and the physiotherapists delivering the intervention. Clinical outcomes on preliminary effects of the intervention will include blood pressure, engagement in physical activity, self-perceived exercise self-efficacy, fatigue, depression, anxiety, stress and health-related quality of life and will be measured at baseline and at 3, 6 and 12 months after the baseline assessments. Discussion We hypothesise that the mHealth delivery of the i-REBOUND programme will be feasible and acceptable in people post str
