Strategies for Effective Improvements to the BioWatch System


Book Description

BioWatch is the Department of Homeland Security's (DHS's) system for detecting an aerosolized biological attack using collectors that are positioned strategically across the country to continuously monitor the air for biological threats. As currently deployed, BioWatch collectors draw air through filters that field technicians collect daily and transport to laboratories, where professional technicians analyze the material collected on the filter for evidence of biological threats. As part of the BioWatch program's efforts to enhance its effectiveness and capabilities, particularly with regard to detecting biological threats in challenging indoor environments, DHS requested the National Academies of Sciences, Engineering, and Medicine hold a workshop to explore alternative and effective biodetection systems for aerosolized biological agents that would meet BioWatch's technical and operational requirements, integrate into the existing system architecture and public health infrastructure, and be deployable by 2027. This publication summarizes the presentations and discussions from the workshop.




BioWatch and Public Health Surveillance


Book Description

Following the attacks of September 11, 2001 and the anthrax letters, the ability to detect biological threats as quickly as possible became a top priority. In 2003 the Department of Homeland Security (DHS) introduced the BioWatch program-a federal monitoring system intended to speed detection of specific biological agents that could be released in aerosolized form during a biological attack. The present volume evaluates the costs and merits of both the current BioWatch program and the plans for a new generation of BioWatch devices. BioWatch and Public Health Surveillance also examines infectious disease surveillance through hospitals and public health agencies in the United States, and considers whether BioWatch and traditional infectious disease surveillance are redundant or complementary.

Enhancing BioWatch Capabilities Through Technology and Collaboration


Book Description

The Department of Homeland Security's (DHS's) BioWatch program aims to provide an early indication of an aerosolized biological weapon attack. The first generation of BioWatch air samplers were deployed in 2003. The current version of this technology, referred to as Generation 2 (Gen-2), uses daily manual collection and testing of air filters from each monitor, a process that can take 12 to 36 hours to detect the presence of biological pathogens. Until April 2014, DHS pursued a next-generation autonomous detection technology that aimed to shorten the time from sample collection to detection to less than 6 hours, reduce the cost of analysis, and increase the number of detectable biological pathogens. Because of concerns about the cost and effectiveness of the proposed Generation 3 system (Gen-3), DHS cancelled its acquisition plans for the next-generation surveillance system. In response to the cancellation announcement, Congress asked the Government Accountability Office (GAO) to conduct a review of the program and the proposed system enhancements that would have been incorporated in BioWatch Gen-3. However, Mike Walter, BioWatch Program manager, Office of Health Affairs, DHS, said that DHS did not agree with all of GAO's characterizations of the BioWatch program efforts described in this review. In response to this, DHS requested that the National Academies of Sciences, Engineering, and Medicine conduct a workshop to further explore the findings of the 2015 GAO report and discuss the impact these findings may have with regard to the future development of the technical capabilities of the BioWatch program. Workshop participants also discussed existing and possible collaborations between BioWatch, public health laboratories, and other stakeholders that could contribute to the enhancement of biosurveillance capabilities at the federal, state, and local levels. This publication summarizes the presentations and discussions from the workshop.




Biodefense in the Age of Synthetic Biology


Book Description

Scientific advances over the past several decades have accelerated the ability to engineer existing organisms and to potentially create novel ones not found in nature. Synthetic biology, which collectively refers to concepts, approaches, and tools that enable the modification or creation of biological organisms, is being pursued overwhelmingly for beneficial purposes ranging from reducing the burden of disease to improving agricultural yields to remediating pollution. Although the contributions synthetic biology can make in these and other areas hold great promise, it is also possible to imagine malicious uses that could threaten U.S. citizens and military personnel. Making informed decisions about how to address such concerns requires a realistic assessment of the capabilities that could be misused. Biodefense in the Age of Synthetic Biology explores and envisions potential misuses of synthetic biology. This report develops a framework to guide an assessment of the security concerns related to advances in synthetic biology, assesses the levels of concern warranted for such advances, and identifies options that could help mitigate those concerns.




Animal Health at the Crossroads


Book Description

The confirmed case of "mad cow" disease (BSE) in June 2005 illustrates the economic impact of disease outbreaks, as additional countries closed their markets to U.S. beef and beef products. Emerging diseases also threaten public health-11 out of 12 of the major global disease outbreaks over the last decade were from zoonotic agents (that spread from animals to humans). Animal Health at the Crossroads: Preventing, Detecting, and Diagnosing Animal Diseases finds that, in general, the U.S. animal health framework has been slow to take advantage of state-of-the-art technologies being used now to protect public health; better diagnostic tests for identifying all animal diseases should be made a priority. The report also recommends that the nation establish a high-level, authoritative, and accountable coordinating mechanism to engage and enhance partnerships among local, state, and federal agencies, and the private sector.




Disaster Resilience


Book Description

No person or place is immune from disasters or disaster-related losses. Infectious disease outbreaks, acts of terrorism, social unrest, or financial disasters in addition to natural hazards can all lead to large-scale consequences for the nation and its communities. Communities and the nation thus face difficult fiscal, social, cultural, and environmental choices about the best ways to ensure basic security and quality of life against hazards, deliberate attacks, and disasters. Beyond the unquantifiable costs of injury and loss of life from disasters, statistics for 2011 alone indicate economic damages from natural disasters in the United States exceeded $55 billion, with 14 events costing more than a billion dollars in damages each. One way to reduce the impacts of disasters on the nation and its communities is to invest in enhancing resilience-the ability to prepare and plan for, absorb, recover from and more successfully adapt to adverse events. Disaster Resilience: A National Imperative addresses the broad issue of increasing the nation's resilience to disasters. This book defines "national resilience", describes the state of knowledge about resilience to hazards and disasters, and frames the main issues related to increasing resilience in the United States. It also provide goals, baseline conditions, or performance metrics for national resilience and outlines additional information, data, gaps, and/or obstacles that need to be addressed to increase the nation's resilience to disasters. Additionally, the book's authoring committee makes recommendations about the necessary approaches to elevate national resilience to disasters in the United States. Enhanced resilience allows better anticipation of disasters and better planning to reduce disaster losses-rather than waiting for an event to occur and paying for it afterward. Disaster Resilience confronts the topic of how to increase the nation's resilience to disasters through a vision of the characteristics of a resilient nation in the year 2030. Increasing disaster resilience is an imperative that requires the collective will of the nation and its communities. Although disasters will continue to occur, actions that move the nation from reactive approaches to disasters to a proactive stance where communities actively engage in enhancing resilience will reduce many of the broad societal and economic burdens that disasters can cause.




Infectious Disease and National Security


Book Description

The pace of global travel, migration, and commerce has brought about an increased risk of a worldwide infectious disease outbreak. This report examines infectious disease within the context of national security and assesses the need for and adequacy of information that will enable U.S. policymakers to prevent and respond to such threats.




Prepositioning Antibiotics for Anthrax


Book Description

If terrorists released Bacillus anthracis over a large city, hundreds of thousands of people could be at risk of the deadly disease anthrax-caused by the B. anthracis spores-unless they had rapid access to antibiotic medical countermeasures (MCM). Although plans for rapidly delivering MCM to a large number of people following an anthrax attack have been greatly enhanced during the last decade, many public health authorities and policy experts fear that the nation's current systems and plans are insufficient to respond to the most challenging scenarios, such as a very large-scale anthrax attack. The U.S. Department of Health and Human Services' Office of the Assistant Secretary for Preparedness and Response commissioned the Institute of Medicine to examine the potential uses, benefits, and disadvantages of strategies for repositioning antibiotics. This involves storing antibiotics close to or in the possession of the people who would need rapid access to them should an attack occur. Prepositioning Antibiotics for Anthrax reviews the scientific evidence on the time window in which antibiotics successfully prevent anthrax and the implications for decision making about prepositioning, describes potential prepositioning strategies, and develops a framework to assist state, local, and tribal public health authorities in determining whether prepositioning strategies would be beneficial for their communities. However, based on an analysis of the likely health benefits, health risks, and relative costs of the different prepositioning strategies, the book also develops findings and recommendations to provide jurisdictions with some practical insights as to the circumstances in which different prepositioning strategies may be beneficial. Finally, the book identifies federal- and national-level actions that would facilitate the evaluation and development of prepositioning strategies. Recognizing that communities across the nation have differing needs and capabilities, the findings presented in this report are intended to assist public health officials in considering the benefits, costs, and trade-offs involved in developing alternative prepositioning strategies appropriate to their particular communities.




The increasing threat of biological weapons


Book Description

With the World Health Organization (WHO), the North Atlantic Treaty Organization (NATO), and the U.S. Blue Ribbon panel publishing reports on the emerging risks of biological weaponry in past months, there is a new sense of urgency regarding biological weapons. In August 2016, the United Nations Secretary General Ban Ki Moon told the Security Council that “non-state actors are actively seeking chemical, biological, and nuclear weapons.” This report presents the changing dynamics of the development and use of biological weapons and the preparation against them. The dynamics relate to technological advances in biotechnology and the concomitant attraction to non-state actors to use biological agents as weapons due to their financial appeal and diverse impact. The relative ease with which biological weapons can be produced, and the intent of non-state actors to use biological weapons- based on historical precedent and recent surge in international terrorism- call for a renewed focus on this field and an increased effort to respond to these developments. We provide illustrations of new policy initiatives in a variety of countries and outline the current state of play in the Netherlands, providing a point of departure to discuss whether the current approach is sufficient to tackle the upcoming issues.
