“…Risk perception by the general public is complex, relying more on intuition rather than on probability-based assessments. [18][19][20] It has been noted that non-experts tend to be swayed by events that are widely publicised, dramatised and image-laden, suggesting that extensive media coverage may influence risk perception, which in turn may affect the likelihood of patients being prepared to accept a transfusion and the willingness of donors to provide blood. 18 Therefore, it is important that the public confidence in the safety of the national blood supply is maintained by ongoing surveillance of EIDs, robust risk assessments and effective communication with stakeholders and the general public.…”

Summary Emerging infectious diseases (EIDs) are infectious diseases whose incidence has increased in humans in the past 20 years or could increase in the near future. EID agents may represent a threat to blood safety if they infect humans, cause a clinically significant illness, include an asymptomatic blood phase in the course of infection, and are transmissible by transfusion. EID agents are typically not well characterised, but there is a consensus that we can expect ongoing outbreaks. Strategies to manage the risk to blood safety from EIDs include ongoing surveillance, regular risk assessments, modelling transfusion transmission risk, and deferral of donors with a recent travel history to outbreak areas. The 2015–16 Zika virus (ZIKV) outbreak in the Americas is the largest reported ZIKV outbreak to date, and it highlights the unpredictable nature of EID outbreaks and how quickly they can become a major public health problem. This ZIKV outbreak has provided evidence of a causal link between the virus and microcephaly in newborns. In assessing the potential risk of ZIKV to blood safety in Australia, it should be noted that a relatively small number of imported ZIKV infections have been reported in Australia, there have been no reported cases of local ZIKV transmission, and the geographical distribution of the potential ZIKV mosquito vector in Australia (Aedes aegypti) is limited to northern Queensland. Moreover, reported transfusion‐transmitted ZIKV cases worldwide are rare. At present, ZIKV represents a low risk to blood safety in Australia.

“…First, it introduces psychometric analysis (Fischhoff et al 1978;Slovic 1987;Slovic et al 1980Slovic et al , 1987 as a means to characterize IS threats with a number of risk attributes and shows how 20 common IS threats differ from one another. Psychometric analysis has been widely used to understand public perception (i.e., perception shared among individuals) of hazards in many domains (Boholm 1998, Duff 2014, Ngo et al 2013, Slovic 2000. This study extends the analysis to the field of IS and demonstrates that IS threats, following similar patterns observed in other types of hazards, can be characterized by two underlying dimensions, unknown risk and dread risk, which reflect the degree to which a risk is understood and the degree to which a risk evokes a feeling of anxiety and fear, respectively.…”

I nformation security (IS) threats are increasingly pervasive, and search engines are being used by the public as the primary tool for searching for relevant information. This research investigates the following two questions: (1) How can different IS threats be characterized and distinguished in terms of their risk characteristics? and (2) how are risk characteristics related to public searches for information on IS threats? Applying psychometric analysis, our analyses of survey data first show that unknown risk and dread risk are two underlying dimensions that can characterize different IS threats. Drawing broadly on the literature of information foraging theory, we examine the influence of risk characteristics on public searches for information on these threats. We utilize a search engine log to extract searches related to IS threats. We develop and estimate a system of equations with correlated individual-specific error terms using the Markov Chain Monte Carlo method. We find that the two risk characteristics exert differential impacts on information search behavior (including types of information sought, number of pages viewed, and length of query). The implications for IS research and practice are discussed.
