Written testimony of OHA National Bio-surveillance Integration Center Acting Director Dr. Aaron Firoved for a Senate Committee on Homeland Security and Governmental Affairs hearing titled “The Federal Perspective on the State of Our Nation’s Biodefense”

Release Date: April 14, 2016

342 Dirksen Senate Office Building

Chairman Johnson, Ranking Member Carper, and distinguished members of the Committee, thank you for inviting me to speak with you today. I appreciate the opportunity to testify on the Department of Homeland Security’s role in biodefense.

The Changing Biological Threat

In the fifteen years since the U.S. anthrax attacks, we have continued to face not only the threat of biological attacks, but also naturally occurring disease outbreaks (e.g., avian influenza, Ebola virus, Zika virus), global pandemics (e.g., H1N1 influenza), and criminal acts using biological agents (e.g., ricin). The threats and risks posed by emerging and re-emerging infectious diseases and the potential research, development, acquisition, and use of biological agents by international terrorist organizations, homegrown violent extremists, and rogue states will continue to challenge our ability to warn, prepare, and protect the Homeland.

The Blue Ribbon Study Panel on Biodefense’s recent National Blueprint for Biodefense made it abundantly clear that the threat of both manmade and natural biological disasters has not waned and, in fact, continues to grow and evolve. The effects of climate change, global connectivity, advances in biotechnology, and increased instability in the Middle East, Africa, and parts of Asia increase the likelihood of a biological event in the Homeland. Synthetic biology and gene editing offer the promise of great medical breakthroughs; however, they also offer international terrorist organizations, homegrown violent extremists, and rogue states similar potential to modify organisms for malicious purposes. In the same vein, naturally-emerging avian influenza outbreaks and antibiotic resistant bacteria reflect increasing risk to the United States. Within 24 hours, an individual infected with a virulent, contagious, potentially-manmade pathogen can land on our shores and spark an outbreak with far reaching national or global consequences. These risks and threats have also been highlighted previously in congressional testimony from Director of National Intelligence James Clapper.

In the wake of these growing threats, the Department of Homeland Security (DHS) remains fully engaged and proactive in attempting to characterize the threat, providing warning of emerging and imminent threats, and coordinating whole of government response. During the most recent Ebola Virus Disease outbreak in West Africa, DHS provided intelligence analysis to the interagency, state and local governments, and first responders, and it directed research to better characterize the threat and fill gaps in public health and operational responses. Additionally, DHS coordinated and implemented enhanced screening for more than 42,000 international passengers at five airports. The Department continues to work with state and local governments, Intelligence Community partners, and federal partners to provide predictive analysis and early warning in addition to longer-term research and development (R&D) that strengthens preparedness and response capabilities and fosters resilient communities. We must remain vigilant and innovative as biological threats continue to evolve and new threats emerge.

Department of Homeland Security’s role in Biodefense

The DHS Office of Health Affairs (OHA), along with the Science and Technology Directorate (S&T), continues to lead the Department’s work with all biodefense stakeholders, from local to federal partners, to understand and meet these threats today and to be ready for the threats that will emerge tomorrow. With in-house experts including physicians, scientists, toxicologists, veterinarians, intelligence and data analysts, and first responders, the Department is positioned to address natural and manmade biological threats in our population as well as in our agriculture and wildlife through biosurveillance, biological detection, and expertise to DHS leaders.

Detection and defense against biological threats, be they acts of terrorism or naturally occurring, remain important mission areas for DHS. For large scale biological events, knowledge as early as possible allows informed decisions that can save American lives. To this end, the Department’s operational biodetection and biosurveillance programs, the BioWatch Program and the National Biosurveillance Integration Center, are critical to our nation’s biodefense. The capabilities are mutually reinforcing – one provides detection of selected threats at their onset in high risk areas, while the other provides public health surveillance at a broader level at later stages. Each capability is supported by a biodefense R&D portfolio in the Department dedicated to creating technology options that address identified and validated capability gaps. R&D helps the Department maintain a longer-range view and ensures operational elements are not caught off guard by emerging or new trends and threats.

The Nation’s biodefense integrates numerous agencies and levels of government, and S&T’s biodefense R&D portfolio serves the full range of interagency, intergovernmental stakeholders. In addition to ongoing R&D programs with OHA, S&T’s portfolio extends to stakeholders outside the Department including protection of livestock from foreign animal diseases, support for acquisition of medical countermeasures, bioassay and diagnostic development, biological forensics programs, and biological event remediation. S&T’s biodefense R&D portfolio is grounded in coordination and close working relationships both within DHS and with external partners.

National Biosurveillance Integration Center (NBIC)

Established in 2004 and transitioned to OHA in 2007, NBIC’s mission is to enable early warning and shared situational awareness of acute biological events and support better decisions through rapid identification, characterization, localization, and tracking for biological events of national significance. Given the evolving biodefense threats that our Nation faces, both manmade and natural, greater coordination among federal, state, local, tribal, and territorial partners is required. NBIC is uniquely situated within DHS to provide a fusion of human health, animal health, and environmental data to develop a comprehensive understanding of the biological threat landscape and emerging incidents to ensure our Nation’s decision-makers have timely, accurate, and actionable information.

To accomplish this, NBIC monitors thousands of data sources and leverages the expertise of fourteen federal departments and agencies, then integrates this array of information into reports on global and national biological incidents that could potentially cause economic damage, social disruption, or loss of life. Over 900 federal and 1,500 state, local, tribal, and territorial offices across this spectrum of human, animal, and environmental health and response have access to NBIC’s reports and analysis.

We are cognizant that reports by the Government Accountability Office (GAO) and the Blue Ribbon Panel on Biodefense have acknowledged the progress that NBIC has made delivering daily situational awareness to our partners, but have pointed out that we still have work to do to fully realize the vision of comprehensive biosurveillance integration. Towards this end, NBIC is working with the Department of Veterans Affairs on a proof of concept for a data initiative that will help to create an aggregated national view of disease trends, while also supporting VA to leverage its Electronic Health Record system. Similarly, NBIC is working with the Department of Defense’s Defense Threat Reduction Agency to deploy new collaboration and analytic tools that will enable biosurveillance analysts from across the government to collaboratively examine and report on emerging biological threats. NBIC’s efforts are also focused on biosurveillance tools and reporting for local officials so that they can address the biological incidents emerging in their own communities, while strengthening national surveillance as a whole. NBIC will continue to advance its capacity to conduct biosurveillance reporting and analysis by developing new collaboration tools, pursuing innovative data sources and methods, and fostering greater stakeholder engagement.

Public Health Emergency Medical Countermeasures Enterprise

Though the stockpiling of medical countermeasures (MCM) for the general public is the responsibility of the Department of Health and Human Services (HHS) Assistant Secretary for Preparedness and Response, DHS does have a role in the process. Federal procurement of MCM is governed by the interagency Public Health Emergency Medical Countermeasures Enterprise (PHEMCE), for which the Chief Medical Officer of DHS serves as the Department’s voting representative.

DHS participates as a voting member of both of the governing bodies of the PHEMCE– the Enterprise Senior Council and Enterprise Executive Committee – which are comprised of Assistant and Deputy Assistant Secretary level department and agency representatives. Additionally, DHS has voting representatives on Interagency Policy Teams covering the breadth of MCM disciplines that perform in-depth analyses of MCM related issues and report back to the governing bodies with recommendations. The structure is designed to leverage government subject matter expertise to produce a threat based, risk informed, prioritized list of MCM needs across the interagency. This prioritized list is balanced with resources, both current and projected, to develop an MCM acquisition and stockpile maintenance plan, which is then thoroughly reviewed before being approved and put into action. This process reassesses the MCM enterprise on an annual basis, and updates recommendations, informed by the most recent information available, risk assessments, and resource constraints.

BioWatch Program

The BioWatch Program is the Nation’s only civilian program that provides early warning in the event of an aerosolized biological attack. The program consists of planning, preparedness, exercising, training, and early detection capabilities. Deployed at more than 30 major metropolitan areas throughout the country, the system is a collaborative effort of health professionals at all levels of government. The program is operated by a team comprised of field operators, laboratory technicians, and public health officials from city, county, state, and federal organizations. Each hour gained through early detection of a biological attack and before the onset of medical symptoms, improves the chances that response efforts will be successful. The BioWatch Program has succeeded in bringing together state and local public health, first responders, and law enforcement personnel, along with locally-deployed federal officials, resulting in communities that are better prepared not only for a biological attack, but also for an all-hazards response.

The current BioWatch system has been, and will continue to be, extensively tested, and the program is advancing plans and building capabilities in early detection and situational awareness. BioWatch builds the collective capabilities across all levels of government to effectively and rapidly mobilize in response to an attack, mitigating the impacts of a potential catastrophic bioterrorism event. The BioWatch Program is a critical component of our Nation’s response to minimize the impacts of a biological attack.

The Department appreciates the GAO report and recommendations on the path forward for the BioWatch Program. GAO clearly recognizes the unique challenges for this system which was rolled out with the best available technology in 2003 to respond to an urgent threat. The relevant technical capabilities available to adversaries have only increased since then, as biotechnologies have continued their global development and dissemination. So the need for BioWatch persists. In the past two years, the capabilities of the system have been independently tested and validated. Four independent tests have been conducted over the last six years that have tested all components of the BioWatch system. This has included extensive testing of our identification assays (laboratory tests that detect selected biological agents), subsystem and system level testing in test chambers using actual threat agents, and open-air testing of simulated agents in as near an operational environment as possible. In addition, the BioWatch Quality Assurance Program has analyzed over 30,400 samples to monitor operations against performance benchmarks and requirements. The results of these tests reinforce confidence in the system’s ability to achieve its mission: detecting a large-scale aerosol release of specific threat agents in our Nation’s most populated areas.

The system’s capability to detect biological agents was further affirmed last year when BioWatch detected the subtype of Francisella tularensis that is pathogenic to humans during confirmed occurrences of that strain of Tularemia in Denver, Colorado. Though the agent was not disseminated by an adversary, these detections took place during a documented uptick in naturally occurring disease. By analyzing available medical surveillance data and discussing the BioWatch detections through the BioWatch National Conference Call, local, state, and federal officials were provided with additional data for decision support in responding to this occurrence of Tularemia. This shows that the BioWatch Program is able to detect an airborne biological agent in the environment.

The BioWatch Program is more than just an environmental detection system. BioWatch also helps strengthen jurisdictional preparedness in the event of a bioterrorism event through coordinating exercises and drills; providing training, guidance and assessments, and standardized methodologies for response; and by enabling a forum for all levels of government to share data and information. Over 500 state and local partners and stakeholders representing a broad cross section of government agencies have participated in BioWatch preparedness activities in the last year. BioWatch has also coordinated environmental assessment activities, including developing initial environmental sampling plans for jurisdictions to help characterize an attack. All of the program’s key elements – including response – are supported by a number of federal departments and agencies, such as HHS including the Centers for Disease Control and Prevention (CDC), the Department of Defense (DOD), the Environmental Protection Agency, and the Federal Bureau of Investigation. BioWatch also supports major events such as Super Bowls and National Special Security Events (e.g., 2015 papal visit to three U.S. cities).

Since 2014, BioWatch has been working with DHS S&T, DOD, and other federal partners to identify technologies that would substantially improve BioWatch operations. These improvements are intended to advance the current “detect to treat” capability. Additionally, BioWatch and the National Biosurveillance Integration Center are working together to improve situational awareness at all levels of government in the event of a biological attack.

State, Local, and First Responder Engagement

Key stakeholders in all our programs are state and local partners. OHA engages with the Association of State and Territorial Health Officials, the National Association of County and City Health Officials, and the Institute of Medicine, to leverage established working groups and information sharing mechanisms for direct engagement with state and local public health officials. This engagement allows for state and local health officials to maintain awareness of, and provide expertise, feedback, and support to, OHA activities, including the BioWatch and NBIC programs.

OHA continues to seek ways to support the first responder community in its preparation and response to biological events. One initiative we are developing is the First Responder Vaccine Initiative (FRVI), which is developing the infrastructure for an anthrax vaccination pilot to evaluate the feasibility of a voluntary pre-event anthrax vaccination program among first responders using anthrax vaccine scheduled to rotate out of the CDC’s Strategic National Stockpile in at least two states. DHS is facilitating transfer of the vaccine from CDC to the states. I thank this Committee for moving S. 1915, Sen. Ayotte’s legislation authorizing the pilot program.


Since the startup of the Department, we have worked hard to strengthen our Nation’s biodefense. We acknowledge and appreciate GAO’s efforts to highlight areas for improvement in the Department’s biodefense programs. We are committed to continued work with our partners and look forward to the Committee continuing to help build and refine these robust programs. We appreciate the Subcommittee for keeping this issue at the forefront and for your continued support to biodefense and homeland security.
