The Globalization of Risk and Risk Perception

Risk communication and vaccines is complex and the nature of risk perception is changing, with perceptions converging, evolving and having impacts well beyond specific geographic localities and points in time, especially when amplified through the Internet and other modes of global communication.This article examines the globalization of risk perceptions and their impacts, including the example of measles and the globalization of measles, mumps and rubella (MMR) vaccine risk perceptions, and calls for a new, more holistic model of risk assessment, risk communication and risk mitigation, embedded in an ongoing process of risk management for vaccines and immunization programmes. It envisions risk communication as an ongoing process that includes trust-building strategies hand-in-hand with operational and policy strategies needed to mitigate and manage vaccine-related risks, as well as perceptions of risk.

The globalization of risk and risk perception: why we need a new model of risk communication for vaccines.

The actual and potential costs of meningitis surveillance in the African meningitis belt: Results from Chad and Niger.

BACKGROUND The introduction of serogroup A meningococcal conjugate vaccine in the African meningitis belt required strengthened surveillance to assess long-term vaccine impact. The costs of implementing this strengthening had not been assessed. METHODOLOGY The ingredients approach was used to retrospectively determine bacterial meningitis surveillance costs in Chad and Niger in 2012. Resource use and unit cost data were collected through interviews with staff at health facilities, laboratories, government offices and international partners, and by reviewing financial reports. Sample costs were extrapolated to national level and costs of upgrading to desired standards were estimated. RESULTS Case-based surveillance had been implemented in all 12 surveyed hospitals and 29 of 33 surveyed clinics in Niger, compared to six out of 21 clinics surveyed in Chad. Lumbar punctures were performed in 100% of hospitals and clinics in Niger, compared to 52% of the clinics in Chad. The total costs of meningitis surveillance were US

0.03, respectively. Laboratory investigation was the largest cost component per surveillance functions, comprising 51% of the total costs in Niger and 40% in Chad. Personnel resources comprised the biggest expense type: 37% of total costs in Niger and 26% in Chad. The estimated annual, incremental costs of upgrading current systems to desired standards were US

Transforming Public Health Surveillance Through Open Public Health Information

Evaluating Cost and Performance for Improved Meningitis Disease Surveillance in Chad

605,912 in Chad, which are 9% and 143% of present costs, respectively. CONCLUSIONS Nigers more robust meningitis surveillance system costs four times more per capita than the system in Chad. Since Chad spends less per capita, fewer activities are performed, which weakens detection and analysis of cases. Countries in the meningitis belt are diverse, and can use these results to assess local costs for adapting surveillance systems to monitor vaccine impact.

Examining the Human Element in Lab Biosafety

In the wake of the recent west African Ebola epidemic, there is global consensus on the need for strong health systems; however, agreement is less apparent on effective mechanisms for establishing and maintaining these systems, particularly in resource-constrained settings and in the presence of multiple and sustained stresses (eg, conflict, famine, climate change, and globalisation). The construction of the International Health Regulations (2005) guidelines and the WHO health systems framework, has resulted in the separation of public health functions and health-care services, which are interdependent in actuality and must be integrated to ensure a continuous, unbroken national health system. By analysing efforts to strengthen health systems towards attaining universal health coverage and investments to improve global health security, we examine areas of overlap and offer recommendations for construction of a unified national health system that includes public health. One way towards achieving universal health coverage is to broaden the definition of a health system.
