Training disaster communication by means of serious games in virtual environments

The training of social skills in organizational settings has become more and more important for an effective communicative exchange between members of staff. Especially in companies where the line of communication has to be fast and unmistakable, e.g. in crisis management units, the regular training of communication skills is therefore indispensable. The DREAD-ED project proposes an innovative, technology-based teaching methodology to meet these needs. The methodology provides a serious game which enables its users to train soft skills in a virtual environment under safe conditions. The current paper presents the results of two trials conducted with crisis managers and university students in Germany

A comparative assessment of the risks of introduction and spread of foot and mouth disease among different pig sectors in Australia

Small-scale pig producers are believed to pose higher biosecurity risks for the introduction and spread of exotic diseases than commercial pig producers. However, the magnitude of these risks are poorly understood. This study is a comparative assessment of the risk of introduction and spread of foot and mouth disease (FMD) through different sectors of the pig industry: 1) large-scale pig producers; 2) small-scale producers (< 100 sows) selling at saleyards and abattoirs; and, 3) small-scale producers selling through informal means. An exposure and consequence assessments were conducted assuming FMD virus was introduced into Australia through illegal importation of infected meat. A quantitative assessment, using scenario trees and Monte Carlo stochastic simulation, was used to calculate the probabilities of exposure and spread. Input data for these assessments were obtained from a series of data gathering exercises among pig producers, industry statistics and literature. Findings of this study suggest there is an Extremely low probability of exposure (8.69 × 10-6 to 3.81 × 10-5) for the three sectors of the pig industry, with exposure through direct swill feeding being 10 to 100 times more likely to occur than through contact with infected feral pigs.. Spread of FMD from the index farm is most likely to occur through movement of contaminated fomites, pigs and ruminants. The virus is more likely to spread from small-scale piggeries selling at saleyards and abattoirs than from other piggeries. The most influential factors on the spread of FMD from the index farm is the ability of the farmer to detect FMD, the probability of FMD spread through contaminated fomites and the presence of ruminants on the farm. Although small-scale producers selling informally move animals less frequently and do not use external staff, movement of pigs to non-commercial pathways could jeopardize animal traceability in the event of a disease outbreak. This study suggest that producers’ awareness on and engagement with legislative and industry requirements in relation to biosecurity and emergency animal disease management needs to be improved. Results from this study could be used by decision-makers to prioritize resource allocation for improving animal biosecurity in the pig industry

A Q fever cluster among workers at an abattoir in south-western Sydney, Australia, 2015

Background: In September 2015, the Public Health Unit of the South Western Sydney Local Health District was notified of two possible Q fever cases. Case investigation identified that both cases were employed at an abattoir, and both cases advised that co-workers had experienced similar symptoms. Public Health Unit staff also recalled interviewing in late 2014 at least one other Q fever case who worked at the same abattoir. This prompted an outbreak investigation. Methods: The investigation incorporated active case finding, microbiological analysis, field investigation and a risk factor survey. Included cases were laboratory definitive or suspected cases occurring from October 2014 to October 2015, residing or working in south-western Sydney. A suspected case had clinically compatible illness, high-risk exposure and was epidemiologically linked to another confirmed case. A confirmed case included laboratory detection of C. burnetii. Results: Eight cases met the case definition with seven confirmed (including a deceased case) and one suspected. The eight cases were all males who had been employed at an abattoir in south-western Sydney during their incubation period; symptom onset dates ranged from November 2014 to September 2015. Field investigation identified multiple potential risk factors at the abattoir, and the majority (75%) of employees were not vaccinated against Q fever despite this high-risk setting. Conclusion: This cluster of Q fever in a single abattoir confirms the significance of this zoonotic disease as an occupational hazard among persons working in high-risk environments. Implementation of Q fever vaccination programmes should eliminate Q fever in high-risk occupational settings

Horse owners’ behaviour: suspecting and reporting of Hendra virus cases

Hendra virus infection is a zoonotic disease which spreads from bats to horses and from horses to people. Transmission spillovers are rare events, but can be fatal to horses and people when they do occur. To date, HeV cases have only occurred in Queensland and northern New South Wales with a total of 83 confirmed cases in horses up to September 2018. The National Hendra Virus Research Program (NHeVRP) was funded by Commonwealth, NSW and Qld governments after a spike in Hendra virus infections in 2011. The “Horse owners and Hendra virus: a longitudinal cohort study to evaluate risk” (HHALTER) project was a component of the NHeVRP and involved collection of survey information from horse owners from 2012 to 2014. The fourth survey in a series of five included questions about owners’ attitudes to reporting a suspected Hendra case. The data are presented here using categorical analysis techniques to explore the relationships between attitudes towards reporting of a case and risk perception and demographic information. Of a total cohort of 1,449 responders, there were 613 (42%) participants responding to some or all of survey four. There were 592 responses to the question “If you saw unusual signs of disease (muscle twitching, nasal discharge etc) in one of your horses, how likely do you think you would be to... consider Hendra virus as a possibility”. Of these 81 said they would not think of Hendra as a possibility at all and 191 thought that Hendra was very or extremely likely. The findings of this study reinforce the importance of an existing/good relationships between horse owners and veterinarians and also identify that the presence of severe or unusual signs of disease would be 'drivers' for reporting a suspect HeV case. Data presented here are likely to represent a ‘best case’

This report was prepared for the Rural Industries Research and Development Corporation in relation to the National Hendra Virus Research Program. It summarises the findings of a three-year mixed methods research study designed to capture factors that influence horse owner Hendra virus (HeV) risk mitigation practices. This research supports the Rural Industries Research and Development Corporation (RIRDC) Hendra Virus Research Priority 2: Improved strategies to prevent transmission of HeV. However, it may also contribute to Research Priority 3: Capacity to detect and respond effectively to HeV incidents

Pregnancy Outcomes After Laparoscopic Radiofrequency Ablation of Uterine Leiomyomas Compared With Myomectomy.

To compare pregnancy outcomes after laparoscopic radiofrequency ablation and myomectomy.The ULTRA (Uterine Leiomyoma Treatment With Radiofrequency Ablation) study is an ongoing multicenter prospective cohort study with longitudinal follow-up up to 5 years comparing outcomes of radiofrequency ablation with myomectomy in premenopausal women older than age 21 years with symptomatic uterine leiomyomas. Participants were queried every 6 months after surgery to assess the incidence of pregnancy and pregnancy outcomes.Among 539 women enrolled in ULTRA, a total of 37 participants (mean age at first pregnancy 35.0±4.7 years) conceived 43 times as of March 2023 (22 radiofrequency ablation, 21 myomectomy). The average length of follow-up time after all procedures was 2.5±1.0 years. The baseline miscarriage rate in the study population was 33.3%. In participants who underwent radiofrequency ablation, 9 of 22 pregnancies (40.9%, 95% CI, 20.3-61.5%) ended in first-trimester miscarriage, 11 resulted in live births (50.0%, 95% CI, 29.1-70.9%), one resulted fetal death at 30 weeks of gestation, and one resulted in uterine rupture during miscarriage treatment with misoprostol 10 weeks after radiofrequency ablation. Among the live births in the radiofrequency ablation group, 45.5% were by vaginal delivery. In the myomectomy group, 9 of 21 pregnancies (42.9%, 95% CI, 21.7-64.0%) ended in first-trimester miscarriage and 12 resulted in live births (57.1%, 95% CI, 36.0-78.3%). There were no significant differences in the likelihood of live birth or miscarriage between the study groups.Full-term pregnancy and vaginal delivery are achievable after radiofrequency ablation of leiomyomas. However, in this interim analysis, the miscarriage rate in both radiofrequency ablation and myomectomy groups was higher than expected for women in this age group. Long-term data collection in the ongoing ULTRA study aims to further understand pregnancy outcomes after radiofrequency ablation compared with myomectomy.ClinicalTrials.gov, NCT0210094

Australian horse owners and their biosecurity practices in the context of Hendra virus

In recent years, outbreaks of exotic as well as newly emerging infectious diseases have highlighted the importance of biosecurity for the Australian horse industry. As the first potentially fatal zoonosis transmissible from horses to humans in Australia, Hendra virus has emphasised the need to incorporate sound hygiene and general biosecurity practices into day-to-day horse management. Recommended measures are widely publicised, but implementation is at the discretion of the individual owner. This cross-sectional study aimed to determine current levels of biosecurity of horse owners and to identify factors influencing the uptake of practices utilising data from an online survey. Level of biosecurity (low, medium, high), as determined by horse owners’ responses to a set of questions on the frequency of various biosecurity practices performed around healthy (9 items) and sick horses (10 items), was used as a composite outcome variable in ordinal logistic regression analyses. The majority of horse owners surveyed were female (90%), from the states of Queensland (45%) or New South Wales (37%), and were involved in either mainly competitive/equestrian sports (37%) or recreational horse activities (35%). Seventy-five percent of owners indicated that they follow at least one-third of the recommended practices regularly when handling their horses, resulting in medium to high levels of biosecurity. Main factors associated with a higher level of biosecurity were high self-rated standard of biosecurity, access to personal protective equipment, absence of flying foxes in the local area, a good sense of control over Hendra virus risk, likelihood of discussing a sick horse with a veterinarian and likelihood of suspecting Hendra virus in a sick horse. Comparison of the outcome variable with the self-rated standard of biosecurity showed that over- as well as underestimation occurred. This highlights the need for continuous communication and education to enhance awareness and understanding of what biosecurity is and how it aligns with good horsemanship. Overall, strengthened biosecurity practices will help to improve animal as well as human health and increase preparedness for future disease outbreaks

“We’ve learned to live with it” − A qualitative study of Australian horse owners’ attitudes, perceptions and practices in response to Hendra virus

Hendra virus causes sporadic zoonotic disease in Australia following spill over from flying foxes to horses and from horses to people. Prevention and risk mitigation strategies such as vaccination of horses or biosecurity and property management measures are widely publicised, but hinge on initiative and action taken by horse owners as they mediate management, care and treatment of their animals. Hence, underlying beliefs, values and attitudes of horse owners influence their uptake of recommended risk mitigation measures. We used a qualitative approach to investigate attitudes, perceptions and self-reported practices of horse owners in response to Hendra virus to gain a deeper understanding of their decision-making around prevention measures. Data presented here derive from a series of in-depth interviews with 27 horse owners from Hendra virus ‘hot spot’ areas in New South Wales and Queensland. Interviews explored previous experience, perceptions and resulting behaviour as well as communication around Hendra virus. All interviews were recorded, transcribed verbatim and analysed in NVivo using thematic analysis. Analysis revealed four major themes: perception of Hendra virus as a risk and factors influencing this perception, Hendra virus risk mitigation strategies implemented by horse owners, perceived motivators and barriers of these strategies, and interaction of perceived risk, motivators and barriers in the decision-making process. Although Hendra virus disease was perceived as a serious threat to the health of horses and humans, individual risk perception diverged among horse owners. Perceived severity, likelihood and unpredictability as well as awareness and knowledge of Hendra virus, trust in information obtained and information pathways, demographic characteristics and personal experience were the main factors influencing Hendra virus risk perceptions. Other key determinants of horse owners’ decision-making process were attitudes towards Hendra virus risk mitigation measures as well as perceived motivators and barriers thereof. Horse owners’ awareness of the necessity to consider individual Hendra virus risk and adequate risk management strategies was described as a learning process, which changed over time. However, different perceptions of risk, barriers and motivators in combination with a weighing up of advantages and disadvantages resulted in different behaviours. These findings demonstrate the multifactorial determinants of cognitive mediating processes and facilitate a better understanding of horse owners’ perspectives on preventive horse health measures. Furthermore, they provide valuable feedback to industry and government stakeholders on how to improve effective risk communication and encourage uptake of recommended risk mitigation measures
