Summary: Information and communication is critical to the successful management of infectious diseases because an effective communication strategy prevents the surge of anxious patients who have not been genuinely exposed to the pathogen ('low risk patients') affecting medical infrastructures (1) and the future transmission of the infectious agent (2). Surge of low risk patients: The arrival of large numbers of low risk patients at hospitals following an infectious diseases emergency would be problematic for three main reasons. First, it would complicate the situation at hospitals receiving exposed patients, delaying the treatment of the acutely ill, creating difficulties of crowd control and tying up medical resources. Second, for the low risk patients themselves, attending hospital following an infectious disease emergency might increase their risk of exposure to the agent in question. Third, the needs of low risk patients may be poorly attended to at hospitals which are already overstretched dealing with medical casualties. Future transmission: Obtaining early information about symptoms and isolating infected patients is the most effective strategy to interrupt the chain of infection in the public in the absence of specific prophylaxis or treatment. Particularly at the beginning of an outbreak, these nonpharmaceutical interventions play an important role in enabling the early detection of signs or symptoms and in encouraging passengers to adopt appropriate preventive behaviour in order to limit the spread of the disease. This thesis includes two papers dealing with this problem: The first part is a systemic literature review of information needs following an infectious disease emergency (Anthrax, SARS, Pneumonic Plague). The key question was: what are the information needs of the public during an infectious disease emergency? The second part is an empirical investigation of information needs and communication strategies at the airport during the early stage of the Influenza Pandemic. The key question here was: what communication strategies help to meet the information needs and to enable the public to behave appropriately and responsibly? Conclusions: Evidence from the anthrax attacks in the United States suggested that a surge of low risk patients is by no means inevitable. Data from the SARS outbreak illustrated that if hospitals are seen as sources of contagion, many patients with non-bioterrorism related health care needs may delay seeking help. Finally, the events surrounding the Pneumonic Plague outbreak of 1994 in Surat, India, highlighted the need for the public to be kept adequately informed about an incident to avoid creating rumours. Clear, consistent and credible information is key to the successful management of infectious disease outbreaks. The results of the empirical investigation suggested that the desire for information is a reflection of current anxiety and does not mirror the objective scientific assessment of exposure. The airport study showed that perceived information needs were directly related to anxiety – the least anxious did not require any further information, the most anxious reported significant information needs concerning medical treatment, public health management and the assessment of the ongoing situation – irrespective of their actual exposure. A communication strategy only focussing on the 'real' exposed individuals neglects the information needs of those worrying about having contracted the virus and seeking medical attendance. Effective communication strategies should enable the general public to detect early signs or symptoms and provide them with behaviour advice to prevent the further transmission of the infectious agent. These include the provision of clear information about the incident, the symptoms and what to do to prevent the further transmission, detailed and regularly updated information in various media formats (telephone, internet, etc.) and rapid triage at hospital entrances to guide patients to the appropriate medical infrastructures. Relevance: These research findings could contribute to a shift in the organisational and communicative approach responding to infectious diseases outbreaks and could be considered relevant for future risk communication and policy decision making.
Responses to recent infectious disease outbreaks, such as to Influenza Pandemic 2009 and the on-going Ebola outbreak in West Africa, reveal the need for new and strengthened approaches to risk communication and governance. The article argues for a fundamental re-conceptualisation of current approaches to risk communication, preparedness planning and response. It calls for a reframing of the way we currently identify and respond to outbreaks around a set of core behaviour-based response patterns. This new model moves away from the current risk communication focus on a plethora of agent-specific threats to five generic response patterns that are based on socially relevant response activities such as 1) controlling vectors, 2) enhancing hygiene, 3) isolation of the sick, 4) protection of the well, and 5) systemic protection of people and their environments. Emphasis is placed on gaining relevant insights into the context specific needs of different communities related to these five patterns. Governance structures are then built and evaluated based on their capacity to collect, communicate, share and prepare the public to take appropriate action related to the five different patterns before, during and after an event. Reframing risk communication and preparedness approaches around a better understanding of the determinants of these general behavioural patterns in infectious control could strengthen infection control literacy, response competence and build resilience of both individuals and health systems to address future epidemics, pandemics and other public health threats.
