Effective surveillance for infectious diseases is an essential component of public health. There are few studies estimating the cost-effectiveness of starting or improving disease surveillance. We present a cost-effectiveness analysis the Integrated Disease Surveillance and Response (IDSR) strategy in Africa.
To assess the impact of the IDSR in Africa, we used pre- and post- IDSR meningococcal meningitis surveillance data from Burkina Faso (1996-2002 and 2003-2007). IDSR implementation was correlated with a median reduction of 2 weeks to peak of outbreaks (25(th) percentile 1 week; 75(th) percentile 4 weeks). IDSR was also correlated with a reduction of 43 meningitis cases per 100,000 (25(th)-40: 75(th)-129). Assuming the correlations between reductions in time to peak of outbreaks and cases are related, the cost-effectiveness of IDSR was $23 per case averted (25(th)-$30; 75(th)--cost saving), and $98 per meningitis-related death averted (25(th)-$140: 75(th)--cost saving).
We cannot absolutely claim that the measured differences were due to IDSR. We believe, however, that it is reasonable to claim that IDSR can improve the cost-effectiveness of public health surveillance.

    ABSTRACT: IntroductionFollowing World Health Organization recommendations set forth in the Global Framework for Immunization Monitoring and Surveillance, Costa Rica in 2009 became the first country to implement integrated vaccine-preventable disease (iVPD) surveillance, with support from the U.S. Centers for Disease Control and Prevention (CDC) and the Pan American Health Organization (PAHO). As surveillance for diseases prevented by new vaccines is integrated into existing surveillance systems, these systems could cost more than routine surveillance for VPDs targeted by the Expanded Program on Immunization.Objectives We estimate the costs associated with establishing and subsequently operating the iVPD surveillance system at a pilot site in Costa Rica.Methods We retrospectively collected data on costs incurred by the institutions supporting iVPD surveillance during the preparatory (January 2007 through August 2009) and implementation (September 2009 through August 2010) phases of the iVPD surveillance project in Costa Rica. These data were used to estimate costs for personnel, meetings, infrastructure, office equipment and supplies, transportation, and laboratory facilities. Costs incurred by each of the collaborating institutions were also estimated.ResultsDuring the preparatory phase, the estimated total cost was 128,000 U.S. dollars (US$), including 64% for personnel costs. The preparatory phase was supported by CDC and PAHO. The estimated cost for 1 year of implementation was US$ 420,000, including 58% for personnel costs, 28% for laboratory costs, and 14% for meeting, infrastructure, office, and transportation costs combined. The national reference laboratory and the PAHO Costa Rica office incurred 64% of total costs, and other local institutions supporting iVPD surveillance incurred the remaining 36%.Conclusions Countries planning to implement iVPD surveillance will require adequate investments in human resources, laboratories, data management, reporting, and investigation. Our findings will be valuable for decision makers and donors planning and implementing similar strategies in other countries.

    ABSTRACT: Despite a significant amount of progress in the past decade, global infectious disease surveillance still often falters, as in the case of the emerging novel coronavirus that has killed at least 17 people in Saudi Arabia. This article argues that we must continuously re-evaluate global infectious disease surveillance systems. It takes stock of problems in various countries' infectious disease surveillance systems and offers recommendations for how to improve surveillance and ensure more rapid reporting. Chief among the recommendations are strategies for reducing fragmentation in global surveillance systems and methods for making these systems less disease-specific. Suggestions are also offered for ways to improve infectious disease surveillance strategies in resource-limited settings.

    ABSTRACT: The region of the Americas pledged to eliminate dog-transmitted human rabies by 2015. After 30 years of sustained efforts, regional elimination appears possible as dog-mediated human rabies cases are at an all-time low, and a number of countries and territories have already eliminated the disease. In this setting, there is an opportunity to generate a framework to support countries strategies in the achievement and maintenance of rabies-free status (RFS). To this end, we describe the development of a multi-criteria decision analysis (MCDA) model to help the evaluation of rabies programmes and the identification of the best investment strategy for countries and territories to improve and efficiently maintain their rabies status. The model contemplates human and animal related capacities, six in each area, to comprehensively assess the wide scope of rabies programmes. An initial elicitation of expert opinion of values and weights for the MCDA model was performed via a web-based questionnaire. Even at this pilot stage, the model produces comparable capacity-scores, and overall (combined for public and animal health areas) as well as area-specific investment strategies. The model is being developed by the Pan American Health Organization (PAHO) as part of the regional efforts towards dog-mediated human rabies elimination and will be presented to the countries for review, refinement, contextualization, and testing. The aspiration is that countries use the model to identify the best allocation of resources towards the elimination of dog-mediated human rabies.
