This heterogeneity renders difficult the comparison of probabilities of freedom from infection estimated from collected surveillance data. The objectives of this review were to outline the methodological and epidemiological considerations for the estimation of probabilities of freedom from infection from surveillance information and review state-of-the-art methods estimating the probabilities of freedom from infection from heterogeneous surveillance data. Substantiating freedom from infection consists in quantifying the evidence of absence from the absence of evidence. The quantification usually consists in estimating the probability of observing no positive test result, in a given sample, assuming that the infection is present at a chosen (low) prevalence, called the design prevalence. The usual surveillance outputs are the sensitivity of surveillance and the probability of freedom from infection. A variety of factors influencing the choice of a method are presented; disease prevalence context, performance of the tests used, risk factors of infection, structure of the surveillance programme and frequency of testing. The existing methods for estimating the probability of freedom from infection are scenario trees, Bayesian belief networks, simulation methods, Bayesian prevalence estimation methods and the STOC free model. Scenario trees analysis is the current reference method for proving freedom from infection and is widely used in countries that claim freedom. Bayesian belief networks and simulation methods are considered extensions of scenario trees. They can be applied to more complex surveillance schemes and represent complex infection dynamics. Bayesian prevalence estimation methods and the STOC free model allow freedom from infection estimation at the herd-level from longitudinal surveillance data, considering risk factor information and the structure of the population. Comparison of surveillance outputs from heterogeneous surveillance programmes for estimating the probability of freedom from infection is a difficult task. This paper is a ‘guide towards substantiating freedom from infection’ that describes both all assumptions-limitations and available methods that can be applied in different settings.

Vetter; Center for Animal Welfare, University of Veterinary Medicine Budapest, Budapest, István Street 2, 1078, Hungary; email: vetter.szilvia@univet.hu AB - The attitudes of veterinarians to the euthanasia of companion animals were investigated using an online questionnaire in Hungary (n = 93), Sweden (n = 145), and Jordan (n = 40). The questions concerned the number of euthanasia performed and the reasons for and circumstances surrounding them, the veterinarians’ opinions on four clinical cases, and the mental burden associated with euthanasia (using a 7-point Likert scale). The monthly number of euthanasia performed by the veterinarians was significantly related to the country (highest in Sweden), but no differences were found by age group (≤ 34 years, 35–54 years, ≥ 55 years) or gender. Untreatable conditions were the most common reason for euthanasia in all countries, but old age was also an important factor in Sweden. Swedish respondents were the most likely, and Jordanians the least likely, to fulfill euthanasia requests about aggressive, but otherwise healthy, animals. The reported mental burden of euthanasia was lowest in Sweden and highest in Jordan, and male veterinarians reported a lower burden than female veterinarians. The attachment of owners to their animals was not associated with the ethical burden of euthanasia experienced by the respondents. Veterinarians who performed more euthanasia per month reported a lower ethical burden. Most respondents considered what they had learned about the topic during their university education to be insufficient. According to our model, veterinarians’ attitudes toward euthanasia are associated with a combination of personal (gender, age, training background) and social (cultural, religious background) factors. Further research on this topic is important, not only for animal welfare rules and practices but also for the protection of veterinarians’ mental health. © 2023 International Society for Anthrozoology (ISAZ).
