Technologies to Enable Autonomous Detection for BioWatch


Book Description

The BioWatch program, funded and overseen by the Department of Homeland Security (DHS), has three main elements-sampling, analysis, and response-each coordinated by different agencies. The Environmental Protection Agency maintains the sampling component, the sensors that collect airborne particles. The Centers for Disease Control and Prevention coordinates analysis and laboratory testing of the samples, though testing is actually carried out in state and local public health laboratories. Local jurisdictions are responsible for the public health response to positive findings. The Federal Bureau of Investigation is designated as the lead agency for the law enforcement response if a bioterrorism event is detected. In 2003 DHS deployed the first generation of BioWatch air samplers. The current version of this technology, referred to as Generation 2.0, requires daily manual collection and testing of air filters from each monitor. DHS has also considered newer automated technologies (Generation 2.5 and Generation 3.0) which have the potential to produce results more quickly, at a lower cost, and for a greater number of threat agents. Technologies to Enable Autonomous Detection for BioWatch is the summary of a workshop hosted jointly by the Institute of Medicine and the National Research Council in June 2013 to explore alternative cost-effective systems that would meet the requirements for a BioWatch Generation 3.0 autonomous detection system, or autonomous detector, for aerosolized agents . The workshop discussions and presentations focused on examination of the use of four classes of technologies-nucleic acid signatures, protein signatures, genomic sequencing, and mass spectrometry-that could reach Technology Readiness Level (TRL) 6-plus in which the technology has been validated and is ready to be tested in a relevant environment over three different tiers of temporal timeframes: those technologies that could be TRL 6-plus ready as part of an integrated system by 2016, those that are likely to be ready in the period 2016 to 2020, and those are not likely to be ready until after 2020. Technologies to Enable Autonomous Detection for BioWatch discusses the history of the BioWatch program, the role of public health officials and laboratorians in the interpretation of BioWatch data and the information that is needed from a system for effective decision making, and the current state of the art of four families of technology for the BioWatch program. This report explores how the technologies discussed might be strategically combined or deployed to optimize their contributions to an effective environmental detection capability.

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.




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.




The Soviet Biological Weapons Program


Book Description

This is the first attempt to understand the full scope of the USSR’s offensive biological weapons research, from inception in the 1920s. Gorbachev tried to end the program, but the U.S. and U.K. never obtained clear evidence that he succeeded, raising the question whether the means for waging biological warfare could be present in Russia today.
