Abstract
The emergence of viral diseases such as Ebola virus disease, Zika virus disease, and the coronavirus disease (COVID-19) has posed considerable challenges to health care systems around the world. Public health strategy to address emerging infectious diseases has depended in part on human behavior change and yet the perceptions and knowledge motivating that behavior have been at times inconsistent with the latest consensus of peer-reviewed science. Part of that disjuncture likely involves the existence and persistence of past ideas about other diseases. To forecast and prepare for future epidemic and pandemic response, we need to better understand how people approach emerging infectious diseases as objects of public opinion during the periods when such diseases first become salient at a population level. In this essay, we explore two examples of how existing mental models of past infectious diseases appear to have conditioned and constrained public response to novel viral diseases. We review previously reported experiences related to Zika virus in Central America and discuss public opinion data collected in the early months of the COVID-19 pandemic. In the case of Zika virus disease, we assess how thinking about earlier mosquito-borne disease seems to have affected public consideration of the virus in Guatemala. In the case of COVID-19, we assess how previous vaccination behavior for a different disease is associated with intention to obtain vaccination for COVID-19 in the future.

Abstract
Epidemics have traditionally been viewed as the widespread occurrence of infectious disease within a community, or a sudden increase above what is typical. But modern epidemics are both more and less than the diffusion of viral entities. We argue that epidemics are 'fire objects', using a term coined by Law and Singleton: They generate locative fears through encounters that focus attention on entities that are unknown or imprecisely known, transforming spaces and humans into indeterminate dangers, alternating appearance and absence. The Ebola epidemic of 2014 had more complex impacts than the number of infections would suggest. We employ multi-sited qualitative interviews to argue that locative fear is the essence of modern global epidemics. In the discussion we contrast Ebola with both the Zika epidemic that followed and the ongoing coronavirus (COVID-19) pandemic.

Abstract
BACKGROUND The Zika virus outbreak in Brazil (2015-2016) affected thousands of children who were born with Congenital Zika Syndrome (CZS). Families play an important role in their care of children with complex needs, yet their knowledge, experience and skills are rarely harnessed in existing interventions to best support these families. OBJECTIVE This study explores the use of mothers as facilitators for a community-based group intervention for children with CZS and their caregivers in Brazil. METHODS Four facilitators were trained to deliver the 10-week intervention called "Juntos". Two were mothers of a child with CZS ("expert mothers") and two were therapists (speech therapist and physiotherapist). The intervention was delivered to three groups, generally including 8-10 caregivers. Two researchers, who were psychologists, observed the groups and held focus group discussions at the end of each session. They undertook semi-structured interviews post intervention with a purposive sample of caregivers, and with the facilitators. Observation notes were collated and summarised. Transcripts were transcribed and thematically analysed using five elements to assess feasibility: acceptability, demand, implementation, practicality and adaptation. RESULTS The use of expert mothers as facilitators was considered to be acceptable and there was demand for their role. Their experiential knowledge was viewed as important for sharing and learning, and supporting and encouraging the group. The intervention was delivered with fidelity by the expert mothers. The practicality of the intervention was facilitated by holding the group sessions in the community, providing transport costs to facilitators and participants, paying expert mothers and therapist facilitators equally and supporting the expert mothers through a mentorship programme. Equal payment with the therapist enabled the expert mothers to better facilitate the groups, through increased confidence in the value of their role. Adaptation of the intervention included development of video resources and mentoring guidelines. CONCLUSION The use of expert mothers as facilitators of caregiver groups provides a unique approach to harness the knowledge, experience, and skills of families to provide care, and is likely to be feasible in similar contexts.

Abstract
This study examines the SNS activities of Singaporean women to assess how they perceive the risk of Zika virus infection based on the consumption of Zika-related news. Results from an online survey (N = 510) confirmed that third-person risk perception exists among study participants. Individual posting of ZIKA-related news on SNSs was negatively associated with third-person perception. Additionally, third-person perception was negatively correlated with preventive behavioral intention. A moderated mediation model analysis revealed that attention to ZIKA-related news on SNSs significantly moderates the indirect relationship between posting news of ZIKA on SNSs and preventive behavioral intention. The findings of this study are expected to increase the understanding of the third-person effect in the context of infectious diseases based on users' SNS activities.

Abstract
Zika virus (ZIKV) infection has a profound impact on the fetal nervous system. The postnatal period is also a time of rapid brain growth, and it is important to understand the potential neurobehavioral consequences of ZIKV infection during infancy. Here we show that postnatal ZIKV infection in a rhesus macaque model resulted in long-term behavioral, motor, and cognitive changes, including increased emotional reactivity, decreased social contact, loss of balance, and deficits in visual recognition memory at one year of age. Structural and functional MRI showed that ZIKV-infected infant rhesus macaques had persistent enlargement of lateral ventricles, smaller volumes and altered functional connectivity between brain areas important for socioemotional behavior, cognitive, and motor function (e.g. amygdala, hippocampus, cerebellum). Neuropathological changes corresponded with neuroimaging results and were consistent with the behavioral and memory deficits. Overall, this study demonstrates that postnatal ZIKV infection in this model may have long-lasting neurodevelopmental consequences.

Abstract
In recent years, many studies have drawn attention to the important role of collective awareness and human behaviour during epidemic outbreaks. A number of modelling efforts have investigated the interaction between the disease transmission dynamics and human behaviour change mediated by news coverage and by information spreading in the population. Yet, given the scarcity of data on public awareness during an epidemic, few studies have relied on empirical data. Here, we use fine-grained, geo-referenced data from three online sources—Wikipedia, the GDELT Project and the Internet Archive—to quantify population-scale information seeking about the 2016 Zika virus epidemic in the U.S., explicitly linking such behavioural signal to epidemiological data. Geo-localized Wikipedia pageview data reveal that visiting patterns of Zika-related pages in Wikipedia were highly synchronized across the United States and largely explained by exposure to national television broadcast. Contrary to the assumption of some theoretical epidemic models, news volume and Wikipedia visiting patterns were not significantly correlated with the magnitude or the extent of the epidemic. Attention to Zika, in terms of Zika-related Wikipedia pageviews, was high at the beginning of the outbreak, when public health agencies raised an international alert and triggered media coverage, but subsequently exhibited an activity profile that suggests nonlinear dependencies and memory effects in the relation between information seeking, media pressure, and disease dynamics. This calls for a new and more general modelling framework to describe the interaction between media exposure, public awareness and disease dynamics during epidemic outbreaks. Despite its importance for public health policy-makers, understanding the impact of media coverage on collective attention during disease outbreaks remains an elusive research task, due to the lack of available data, especially at high spatial granularity. In this paper, we study the dynamics of collective attention received by the 2016 Zika epidemic in the USA and its interplay with the media coverage of the outbreak, at level of US states and cities. We measure the attention to Zika through geo-localized Wikipedia page view data, and we compare it with mentions of Zika in US news outlets and TV shows. We also compare the collective attention received by the outbreak with the incidence of Zika reported by the US Centers for Disease Control and Prevention in each state. We find that the attention dynamics was highly synchronized across states, irrespective of the local risk of transmission of the virus. By building a linear regression model, we show that the dynamics of collective attention is highly predictable, even at state level, only based on the national media coverage received by the outbreak.

Abstract
Perceptions of infectious diseases are important predictors of whether people engage in disease-specific preventive behaviors. Having accurate beliefs about a given infectious disease has been found to be a necessary condition for engaging in appropriate preventive behaviors during an infectious disease outbreak, while endorsing conspiracy beliefs can inhibit preventive behaviors. Despite their seemingly opposing natures, knowledge and conspiracy beliefs may share some of the same psychological motivations, including a relationship with perceived risk and self-efficacy (i.e., control). The 2015-2016 Zika epidemic provided an opportunity to explore this. The current research provides some exploratory tests of this topic derived from two studies with similar measures, but different primary outcomes: one study that included knowledge of Zika as a key outcome and one that included conspiracy beliefs about Zika as a key outcome. Both studies involved cross-sectional data collections that occurred during the same two periods of the Zika outbreak: one data collection prior to the first cases of local Zika transmission in the United States (March-May 2016) and one just after the first cases of local transmission (July-August). Using ordinal logistic and linear regression analyses of data from two time points in both studies, the authors show an increase in relationship strength between greater perceived risk and self-efficacy with both increased knowledge and increased conspiracy beliefs after local Zika transmission in the United States. Although these results highlight that similar psychological motivations may lead to Zika knowledge and conspiracy beliefs, there was a divergence in demographic association.

Abstract
We aimed to explore the engagement of fathers in a community-based group intervention (Juntos) for children with congenital Zika syndrome (CZS) and their caregivers in Brazil. Six Juntos groups were facilitated from August 2017 to May 2018. We conducted a qualitative study to evaluate the feasibility and acceptability of the intervention for fathers of children with CZS. Methods included participant observation, focus group discussions, and semi-structured interviews of fathers with a child enrolled in the program. Data collected were transcribed, coded and thematically analyzed to explore father preference for, and beliefs about the intervention and to assess potential barriers and enablers to their involvement. Forty-nine families (61 participants) enrolled, of whom 20% (12/61) were fathers. Seven (58%) fathers attended more than 7 out of 10 sessions. The content of Juntos was found to be acceptable to those fathers who attended. Participation in the group offered fathers the opportunity to share experiences of caring for their child and demonstrate their importance as care agents. Work commitments, and the view of mothers as primary caregivers were barriers to engagement of fathers. Facilitators to engagement included a presentation of clear objectives for fathers’ involvement and the opportunity to learn a practical skill related to caring for their child. A better understanding of the perspectives of fathers is crucial to help increase their involvement in parenting interventions.

Abstract
T cells clear virus from the CNS and dynamically regulate brain functions, including spatial learning, through cytokine signaling. Here we determined whether hippocampal T cells that persist after recovery from infection with West Nile virus (WNV) or Zika virus (ZIKV) impact hippocampal-dependent learning and memory. Using newly established models of viral encephalitis recovery in adult animals, we show that in mice that have recovered from WNV or ZIKV infection, T cell-derived interferon-γ (IFN-γ) signaling in microglia underlies spatial-learning defects via virus-target-specific mechanisms. Following recovery from WNV infection, mice showed presynaptic termini elimination with lack of repair, while for ZIKV, mice showed extensive neuronal apoptosis with loss of postsynaptic termini. Accordingly, animals deficient in CD8+ T cells or IFN-γ signaling in microglia demonstrated protection against synapse elimination following WNV infection and decreased neuronal apoptosis with synapse recovery following ZIKV infection. Thus, T cell signaling to microglia drives post-infectious cognitive sequelae that are associated with emerging neurotropic flaviviruses.

Abstract
Since the beginning of the Zika virus epidemic, the Brazilian Ministry of Health has reported over 2000 confirmed cases of microcephaly associated with Zika virus in Brazil, with the cases concentrated in the northeast states. The Zika epidemic reopened a debate in Brazil that has played out in the national newspapers about expanding the abortion law to provide autonomy and legal protection to women. The argument for expanding the abortion law to include microcephaly secondary to Zika virus infection called for autonomy for women and, more broadly, protection of reproductive rights. The argument against expanding the current abortion law was separated into two main moral veins: those citing eugenics and those citing religious beliefs. However, the debate on abortion in the case of microcephaly accomplished more than giving a voice to two different viewpoints; it exposed health disparities that exist in Brazil, which were magnified by Zika virus, and reopened the political arena for discussion of the abortion law.

Abstract
After the discovery that Zika virus (ZIKV) could cause microcephaly and other birth defects, we have scrambled to understand how. Now, spreading along with the virus is misinformation that a ZIKV mutation is responsible for microcephaly. Putting too much onus on a single mutation could enhance a crisis in India.

Abstract
OBJECTIVE The objective of this study was to explore the knowledge, thoughts, and beliefs regarding the Zika virus and its prevention in a community of residents in the municipality of Caguas, Puerto Rico, and elicit their concerns and perceptions of risk. METHODS A quantitative, non experimental, descriptive, cross-sectional correlational study was conducted in a community in Caguas, Puerto Rico. A structured questionnaire was administered to a sample of 158 residents, aged 21 and older, who participated voluntarily. The data were analyzed using SPSS version 17 via univariate and bivariate analysis. RESULTS Of 158 surveyed, 64.6% were women; with a population average of 53.85 years. Of the respondents who believed that they would be affected in some way if they were infected by the Zika virus, over half (52.3%) felt that the virus represented a significant threat to their emotional stability. Of those who perceived emotional threat, 39.5% (n=32) continued to study after completing high school (X2=9.217, p=0.027), 57.9% (n=55) had private health insurance (X2=6.325; p=0.042), and 67.9% (n=55) reported it was little or unlikely to become infected (X2= 6.783; p=0.034). Out of those concerned, 57.4% (n=54) considered Zika very or extremely severe (X2=22.827, p<0.001) and 98.9% (n=93) clean the house surroundings as a preventive measure (X2 = 4.951, p=0.026). Lack of interest was the most common reason identified for not complying with preventive actions by the residents (89.2%). CONCLUSION The underestimation both of the risk concerning the Zika virus and of its consequences was evident. This study reaffirms the need to develop a network that effectively and constantly communicates risk estimates, doing so while addressing the specific needs within the communities served by that network. Community interventions aimed at improving the benefits of and reducing the risks associated with and the perceived barriers to preventive behaviors are needed.

Abstract
Background This study examined the influences of information sources on Zika-relevant knowledge and behaviors in US households containing members who are pregnant, intend to become pregnant, or have a higher probability of unintended pregnancy in Zika-affected regions (i.e. respondents who are younger, are black, have less education, are unmarried, and reside in the southern USA). Methods Over 32 000 US adults completed a survey measuring Zika-relevant knowledge and behaviors along with information sources (e.g. discussing Zika with practitioners), general media usage (e.g. TV) and demographic information over 30 weeks. Results Respondents in the group with (versus without) either pregnancy or intended pregnancy were more likely to use all information sources, which in turn created differences in knowledge and behavior responses. To gauge information sources in US-South respondents with a high probability of having a household member with unintended pregnancy based on demographics, younger, less-educated, unmarried, black respondents had fewer Zika discussion with practitioners than another group. Conclusions Efforts to increase Zika-related knowledge and protective behaviors should target households with members who are pregnant or intending to become pregnant via practitioners, family and friends. Additional efforts should target information channels to reach younger, less educated, unmarried, black respondents, which are at risk for unintended pregnancy.

Abstract
Two 2017 experiments with a U.S. national opportunity sample tested effects of location, psychological distance (PD), and exposure to location-related information on Americans' Zika risk views and behavioral intentions. Location-distance from mosquito transmission of the virus in Florida and Texas; residence within states with 100+ Zika infections; residence within potential mosquito vector ranges-had small, inconsistent effects. Hazard proximity weakly enhanced personal risk judgments and concern about Zika transmission locally. It also increased psychological proximity, and intentions of mosquito control, avoiding travel to Zika-infected areas, and practicing safe sex. PD-particularly social and geographical distance, followed by temporal distance, with few effects for uncertainty-modestly and inconsistently decreased risk views and intentions. Exposure to location-related information from the U.S. Centers for Disease Control and Prevention website-naming states with 100+ Zika cases; maps of potential mosquito vector habitat-increased risk views and psychological closeness, but not intentions; maps had slightly stronger if inconsistent effects versus prevalence information. Structural equation modeling (SEM) of a location > PD > risk views > intention path explained modest variance in intentions. This varied in degree and kind (e.g., which location measures were significant) across behaviors, and between pre- and postinformation exposure analyses. These results suggest need for both theoretical and measurement advances regarding effects of location and PD on risk views and behavior. PD mediates location effects on risk views. Online background information, like that used here, will not enhance protective behavior without explicitly focused communication and perhaps higher objective risk.

Abstract
The recent Zika outbreak and its link to microcephaly and other birth defects in infants exposed in utero have garnered widespread international attention. Based on the severity of birth defects the extent of impairment in these infants is expected to be profound; however, virtually nothing is known regarding the developmental and behavioral sequela of congenital Zika syndrome. This pilot study collected parent-reported patterns of development and sleep in 47 infants with confirmed congenital Zika syndrome who are being followed for clinical services at the Altino Ventura Foundation (FAV) in Recife, Brazil. With assistance from clinicians at FAV, caregivers completed Brazilian Portuguese versions of the Ages and Stages Questionnaire, 3rd edition (ASQ-3) and the Brief Infant Sleep Questionnaire (BISQ). All infants were between 13–22 months of age at the time of the assessment. At 16 months of age, none of the children displayed age appropriate developmental skills. Most (~ 75%) mastered some communication and gross motor skills at around a 6–8-month level. Communication and gross motor skills were relative strengths for the sample, while problem-solving and fine motor skills were relative weaknesses. Sleep was noted to be a problem for around 18% of the sample. In utero exposure to the Zika virus will have lifelong consequences for affected children and their families. Understanding the developmental and behavioral trajectories of affected infants will help identify appropriate family supports to improve quality of life.

Abstract
Despite having been broadly advertised by the mass media, many negative consequences of the Zika virus have been less significant than originally predicted. It is likely that after a few months from the epidemic's onset, personal experience with the virus has altered the person's way to deal with the disease. This study explores the relation between exposure to Zika virus and the social representation of the epidemic. More specifically, one analyzes if increased exposure to the risk of Zika infection changes the characteristics of the web of meanings surrounding the epidemic. Between August and November of 2016, 150 interviews were conducted in the municipality of Governador Valadares, Minas Gerais State, Brazil. Based on the Free Words Association Technique, data on evocations related to the Zika virus were modeled by social network analysis, allowing the characterization of the web of meanings by level of exposure to the risk of Zika infection. The analysis performed here suggests that those never infected by any disease transmitted by the Aedes aegypti mosquito have a lesser representation, incorporating information from the media through lay thinking. In contrast to those with low levels of exposure, the social representation of people infected by Zika is associated with meanings related to the most common symptoms, such as pain, rash, and itching. Personal experience seems to shape the social representation of the disease, increasing the focus on its proximate consequences. Public campaigns designed to foster protective behavior should take into consideration the heterogeneity in the representations of this epidemic to improve adherence to preventive behavior.

Abstract
Incidence of neurologic manifestations associated with Zika virus infection has been increasing. In 2016, neuropsychological and cognitive changes developed in an adolescent after travel to a Zika virus–endemic area. Single-photon emission computed tomography and neuropsychological testing raised the possibility that Zika virus infection may lead to neuropsychiatric and cognitive symptoms.

Abstract
Background French Guiana is a territory that has a decades-long history of dengue outbreaks and more recently, in 2014, a chikungunya outbreak. Zika virus (ZIKV) emerged in late 2015 and subsequently led to an important outbreak. Methodology/Principal findings A cross-sectional phone survey was conducted among the general population during the outbreak in June 2016 with a total of 1,129 individuals interviewed to assess perceptions, knowledge and behaviors regarding zika infection. The population seemed aware of zika, and perceived the infection as a more serious health threat than other common mosquito-borne diseases. Furthermore, both the perceptions and behaviors related to zika and its prevention were found to vary considerably among different social groups, geographic areas and gender; less educated female participants were found to perceive the disease as more worrisome and were less likely to adopt protective behaviors. Moreover, female population has been particularly responsive to awareness campaigns and rapidly understood the extent of risks associated with ZIKV infection. Conclusions/Significance These results revealed that ZIKV appeared at the time of the survey as a new health threat that concerns the public more than chikungunya and dengue fever with differences observed among subgroups of population. These results have implications for the development of multifaceted infection control programs, including strategies for prevention and awareness, helping the population to develop an accurate perception of the threat they are facing and encouraging behavior changes. Although dengue fever has been a focus of many awareness campaigns in Latin America, very little information is available about beliefs, attitudes and behaviors regarding vector-borne diseases among the population of French Guiana. Following the end of the first chikungunya outbreak and at the initial onset of the first zika outbreak, a quantitative survey was conducted among 1129 individuals aiming to study the emotional, cognitive and behavioral response to the risk of zika infection and assess variations among different groups of population. People from French Guiana were found to perceive zika substantially differently from other Aedes mosquito-borne diseases. Overall, ZIKV appeared at the time of the survey as a new health threat that makes the population more scared than chikungunya and dengue fever. Furthermore, both the beliefs and behaviors related to zika and its prevention were found to vary considerably among different social groups, gender and geographic areas. Education had an impact on perceptions and behaviors among women. Female population has been particularly responsive to awareness campaigns and rapidly understood the extent of risks associated with ZIKV infection. Overall, findings emphasize the importance of developing appropriate and relevant strategies helping population to engage in protective behaviors adapted to the health threat they are facing. Given the importance of the public response and precautionary actions to control the spread of an emergent threat, additional research on risk perceptions and other behavioral determinants is warranted.

Abstract
INTRODUCTION In 2015, it was observed a rise in the number of microcephalic newborns associated with a history of non-specific febrile sickness and rash during pregnancy in Brazil. Since then, microcephaly has emerged as a public health concern. A few months after, the causal relation between congenital microcephaly and the Zika virus was discovered. Zika virus, an arbovirus, is a new TORCH member that leads to congenital infection through vertical transmission and harms the developing brain, disrupting synaptogenesis, and causing other central nervous system lesions. OBJECTIVE The purpose of this article is to report the congenital Zika syndrome (CZS) and to emphasize the need for follow-up of the affected children to better know the evolutionary history of this new agent and to optimize the provision of healthcare and improve the quality of life of these patients. METHODS We review the most relevant literature about clinical manifestations and neuroimaging findings related to neurotropism of Zika virus to characterize the congenital Zika syndrome and suggest the systematization of some exams and procedures to evaluate children exposed to ZIKV with or without microcephaly, according to the author's own experience. CONCLUSIONS Vertical ZIKV infection can cause a wide spectrum of neurological manifestations that go beyond microcephaly, and even the non-microcephalic child should be followed during the first years of life, because infection may be asymptomatic or lead to neuropsicomotor delay, epilepsy, and visual abnormalities. The appropriate prospective multidisciplinary follow-up of these patients aims to understand the natural history of this new agent and to provide a better development and quality of life for them and their families.

Abstract
BACKGROUND As the incidence of Zika infection accelerated in Central and South American countries from November 2015 through April 2016, U.S. public health officials developed vector control and risk communication strategies to address mosquito-borne and sexual modes of transmission. This study reports upon U.S. perceptions of the Zika virus prior to domestic transmission, and analyzes the association of socio-economic, political, knowledge and risk factors with population receptivity to selected behavioral, environmental, and clinical intervention strategies. METHODS A representative sample of 1,233 U.S. residents was drawn from address-based telephone and mobile phone lists, including an oversample of 208 women of child-bearing age living in five U.S. southern states. Data were collected between April and June, 2016, and weighted to represent U.S. population distributions. RESULTS Overall, 78% of the U.S. population was aware of Zika prior to domestic transmission. Those unaware of the novel virus were more likely to be younger, lower income, and of Hispanic ethnicity. Among those aware of Zika, over half would delay pregnancy for a year or more in response to public health warnings; approximately one third agreed with a possible vector-control strategy of targeted indoor spraying by the government; and nearly two-thirds agreed that the government should make pregnancy-termination services available to women who learn their fetus had a Zika-related birth defect. Receptivity to these public health interventions varied by age, risk perception, and knowledge of the virus. CONCLUSION Risk salience and population receptivity to public health interventions targeting a novel virus can be conditioned on pre-existing characteristics in the event of an emerging infectious disease. Risk communicators should consider targeted strategies to encourage adoption of behavioral, environmental, and clinical interventions.

Abstract
The threat of a United States (U.S.) Zika virus pandemic during 2015-2016 was associated with public anxiety. Such threats represent opportunities to examine hypotheses about health anxiety. The present study investigated psychological predictors of Zika-related anxiety during the 2015-2016 outbreak. U.S. adults (N = 216) completed a battery of measures assessing Zika-related anxiety as well as psychological variables hypothesized to predict anxious responding to the threat of a domestic Zika outbreak. Contrary to hypotheses, regression analyses indicated that only contamination severity overestimates and greater Zika knowledge significantly predicted Zika-related anxiety. Study limitations and clinical implications are discussed.

Abstract
OBJECTIVES The Zika virus (ZIKV) outbreak in the Americas in 2015-2016 posed a novel global threat due to the association with congenital malformations and its rapid spread. Timely information about the spread of the disease was paramount to public health bodies issuing travel advisories. This paper looks at the online interaction with a national travel health website during the outbreak and compares this to trends in internet searches and news media output. METHODS Time trends were created for weekly views of ZIKV-related pages on a UK travel health website, relative search volumes for 'Zika' on Google UK, ZIKV-related items aggregated by Google UK News and rank of ZIKV travel advisories among all other pages between 15 November 2015 and 20 August 2016. RESULTS Time trends in traffic to the travel health website corresponded with Google searches, but less so with media items due to intense coverage of the Rio Olympics. Travel advisories for pregnant women were issued from 7 December 2015 and began to increase in popularity (rank) from early January 2016, weeks before a surge in interest as measured by Google searches/news items at the end of January 2016. CONCLUSIONS The study showed an amplification of perceived risk among users of a national travel health website weeks before the initial surge in public interest. This suggests a potential value for tools to detect changes in online information seeking behaviours for predicting periods of high demand where the routine capability of travel health services could be exceeded.
