Committee on Veterans Affairs
United States House of Representatives
Bioterrorism:
CDCs
Public Health Response
Statement of
Kevin Yeskey, M.D.
Director,
Bioterrorism Preparedness and
Response Program,
National Center for Infectious
Diseases,
Centers for Disease Control and
Prevention,
U.S. Department of Health and Human
Services
Good morning, Mr. Chairman and Members of the
Subcommittee. I am Dr. Kevin Yeskey, Director, Bioterrorism
Preparedness and Response Program, National Center for Infectious
Diseases, Centers for Disease Control and Prevention (CDC). Thank
you for the opportunity to discuss CDCs
public health response to the threat of bioterrorism. I will update
you on CDCs
status of implementing the overall goals of our bioterrorism
preparedness program.
As has been highlighted recently, increased vigilance
and preparedness for unexplained illnesses and injuries are an
essential part of the public health effort to protect the American
people against bioterrorism. Prior to the September 11 attack on
the United States, CDC was making substantial progress toward
defining, developing, and implementing a nationwide public health
response network to increase the capacity of public health officials
at all levelsfederal,
state, and localto
prepare for and respond to deliberate attacks on the health of our
citizens. The events of September 11 were a defining moment for all
of us, and since then we have dramatically increased our levels of
preparedness and are implementing plans to increase it even further.
Public Health Leadership
The Department of Health and Human Services
(DHHS) anti-bioterrorism efforts are focused on improving the nation's
public health surveillance network to quickly detect and identify the
biological agent that has been released; strengthening the capacities
for medical response, especially at the local level; expanding the
stockpile of pharmaceuticals for use if needed; expanding research on
disease agents that might be released, rapid methods for identifying
biological agents, and improved treatments and vaccines; and
preventing bioterrorism by regulation of the shipment of hazardous
biological agents or toxins.
As the nations
disease prevention and control agency, it is CDCs
responsibility on behalf of DHHS to provide national leadership in the
public health and medical communities in a concerted effort to detect,
diagnose, respond to, and prevent illnesses, including those that
occur as a result of a deliberate release of biological agents. This
task is an integral part of CDCs
overall mission to monitor and protect the health of the U.S.
population.
In 1998, CDC issued Preventing Emerging Infectious
Diseases: A Strategy for the 21st Century, which describes CDCs
plan for combating todays
emerging diseases and preventing those of tomorrow. It focuses on
four goals, each of which has direct relevance to preparedness for
bioterrorism: disease surveillance and outbreak response; applied
research to identify risk factors for disease and to develop
diagnostic tests, drugs, vaccines, and surveillance tools;
infrastructure and training; and disease prevention and control. This
plan was developed with input from state and local health departments,
disease experts, and partner organizations such as the American
Society for Microbiology, the Association of Public Health
Laboratories, the Council of State and Territorial Epidemiologists,
and the Infectious Disease Society of America. It emphasizes the need
to be prepared for the unexpected
whether it is a naturally occurring influenza pandemic or the
deliberate release of anthrax by a terrorist. It is within the
context of these overall goals that CDC is addressing preparing our
nations
public health infrastructure to respond to acts of biological
terrorism. In addition, CDC presented in March 2001 a report to the
Senate entitled Public Health's Infrastructure: A Status Report.
Recommendations in this report complement the strategies outlined for
emerging infectious diseases and preparedness and response to
bioterrorism. These recommendations include training of the public
health workforce, strengthening of data and communications systems,
and improving the public health systems at the state and local level.
CDCs
Strategic Plan for Bioterrorism
CDC outlined necessary steps for strengthening public
health and healthcare capacity to protect the nation against
bioterrorist threats in its April 21, 2001, MMWR release of
Biological and Chemical Terrorism: Strategic Plan for Preparedness and
Response - Recommendations of the CDC Strategic Planning Workgroup.
This report reinforces the work CDC has been contributing to this
effort since 1998 and lays a framework from which to enhance public
health infrastructure. In keeping with the message of this report,
five key focus areas have been identified which provide the foundation
for local, state, and federal planning efforts: Preparedness and
Prevention, Detection and Surveillance, Diagnosis and Characterization
of Biological and Chemical Agents, Response, and Communication. These
areas capture the goals of CDCs
Bioterrorism Preparedness and Response Program for general
bioterrorism preparedness.
·
Preparedness and Prevention
CDC has been working to ensure that all levels of the
public health community
federal,
state, and local
are prepared to work in coordination with the medical and emergency
response communities to address the public health consequences of
biological and chemical terrorism.
CDC has created diagnostic and epidemiological
guidelines for state and local health departments and will continue to
help states conduct drills and exercises to assess local readiness for
bioterrorism. For example, in November 2001 the Centers for Disease
Control and Prevention (CDC) released "Interim Smallpox Response Plan
and Guidelines," which identifies many of the federal, state, and
local public health activities that would need to be undertaken in a
smallpox emergency, including response plan implementation,
notification procedures for suspected cases, CDC and state and local
responsibilities and activities, and CDC vaccine and personnel
mobilization.
In addition, CDC, the Food and Drug Administration
(FDA), the National Institutes of Health (NIH), the Agency for
Healthcare Research and Quality (AHRQ), the Department of Defense (DoD),
and other agencies are facilitating the availability of medical
countermeasures, and supporting and encouraging research to address
scientific issues related to bioterrorism. In some cases, new
vaccines, antitoxins, or innovative drug treatments need to be
developed, manufactured, and/or stocked. Moreover, we need to learn
more about the pathogenesis and epidemiology of the infectious
diseases which do not affect the U.S. population currently. We have
only limited knowledge about how artificial methods of dispersion may
affect the infection rate, range of illness, and public health impact
of these biological agents.
·
Detection and Surveillance
As was evidenced in the anthrax attacks in Florida, New
York, and Washington, DC, the initial detection of a biological
terrorist attack occurs at the local level. Therefore, it is
essential to educate and train members of the medical community
both public and private who may be the
first to examine and treat the victims. It is also necessary to
upgrade the surveillance systems of state and local health
departments, as well as within healthcare facilities such as
hospitals, which will be relied upon to spot unusual patterns of
disease occurrence and to identify any additional cases of illness.
CDC is providing terrorism‑related training to epidemiologists and
laboratorians, infection control personnel, emergency responders,
emergency department personnel and other front‑line health‑care
providers, and health and safety personnel. CDC is providing
educational materials regarding potential bioterrorism agents to the
medical and public health communities on its website for Public
Health Emergency Preparedness and Response at
www.bt.cdc.gov.
CDC is working with partners such as the Johns Hopkins Center for
Civilian Biodefense Studies (www.hopkins‑biodefense.org)
and the Infectious Diseases Society of America to develop training and
educational materials for incorporation into medical and public health
graduate and post-graduate curricula. With public health partners,
CDC is spearheading the development of the National Electronic Disease
Surveillance System, which will facilitate automated, timely
electronic capture of data from the healthcare system.
·
Diagnosis and Characterization of Biological and Chemical Agents
To ensure that prevention and treatment measures can
be implemented quickly in the event of a biological or chemical
terrorist attack, rapid diagnosis is critical. CDC has developed
guidelines and quality assurance standards for the safe and secure
collection, storage, transport, and processing of biologic and
environmental samples. In collaboration with other federal and
non-federal partners, CDC is co-sponsoring a series of training
exercises for state public health laboratory personnel on requirements
for the safe use, containment, and transport of dangerous biological
agents and toxins. CDC is also enhancing its efforts to foster the
safe design and operation of Biosafety Level 3 laboratories, which are
required for handling many highly dangerous pathogens. Furthermore,
CDC is developing a Rapid Toxic Screen to detect peoples
exposure to 150 chemical agents using blood or urine samples.
·
Response
A decisive and timely response to a biological
terrorist event involves a fully documented and well rehearsed plan of
detection, epidemiologic investigation, and medical treatment for
affected persons, and the initiation of disease prevention measures to
minimize illness, injury and death. CDC is addressing this by (1)
assisting state and local health agencies in developing their plans
for investigating and responding to unusual events and unexplained
illnesses, and (2) bolstering CDCs
capacities within the overall federal bioterrorism response effort.
CDC has formalized draft plans for the notification and mobilization
of personnel and laboratory resources in response to a bioterrorism
emergency, as well as overall strategies for vaccination, and
development and implementation of other potential outbreak control
strategies such as isolation and quarantine measures. In addition,
CDC is developing national standards to ensure that respirators used
by first responders and by other health care providers responding to
terrorist acts provide adequate protection against weapons of
terrorism.
·
Communication Systems
Rapid and secure communications are crucial to ensure a
prompt and coordinated response to an intentional release of a
biological agent. Thus, strengthening communication among clinicians,
emergency rooms, infection control practitioners, hospitals,
pharmaceutical companies, and public health personnel is of paramount
importance. To this end, CDC is making a significant investment in
building the nations
public health communications infrastructure through the Health Alert
Network (HAN). HAN is a nationwide program to establish the
communications, information, distance-learning, and organizational
infrastructure for a new level of defense against health threats,
including bioterrorism. CDC has also established the Epidemic
Information Exchange (Epi-X), a secure, web-based
communications system that provides information sharing capabilities
to state and local health officials.
Ongoing communication of accurate and up-to-date
information helps calm public fears and limit collateral effects of
the attack. CDC communicates with the public directly through its
website on emergency preparedness and through a public inquiry
telephone and email system, which, during the anthrax epidemiological
investigation, responded to hundreds of questions daily. In addition,
CDC communicates to the public by releasing daily updates to the news
media, answering inquiries from the press and providing medical
experts for interviews.
The National
Pharmaceutical Stockpile
Another integral component of public health
preparedness at CDC has been the development of a National
Pharmaceutical Stockpile (NPS), which is mobilized in response to an
episode caused by a biological or chemical agent. The role of the CDCs
NPS program is to maintain a national repository of life-saving
pharmaceuticals and medical materiel that can be delivered to the site
or sites of a biological or chemical terrorism event in order to
reduce morbidity and mortality in a civilian population. The NPS is a
backup and means of support to state and local first responders,
healthcare providers, and public health officials. The NPS program
consists of a two-tier response: (1) 12-hour push packages, which are
pre-assembled arrays of pharmaceuticals and medical supplies that can
be delivered to the scene of a terrorism event within 12 hours of the
federal decision to deploy the assets and that will make possible the
treatment or prophylaxis of disease caused by a variety of threat
agents; and (2) a Vendor-Managed Inventory (VMI) that can be tailored
to a specific threat agent.
For the first time ever, CDC deployed the National
Pharmaceutical Stockpile (NPS) in September, sending push packages of
medical materiel to New York City and Washington, DC. In response to
the cases of anthrax exposure, this program was also used to deliver
antibiotics for post-exposure prophylaxis to employees in affected
buildings, postal workers, mail handlers, and postal patrons. In
order to facilitate the procurement of the pharmaceuticals, medical
supplies, and antidotes that comprise the NPS, CDC established an
interagency agreement with the National Acquisition Center of the
Department of Veterans Affairs (VA) in November of 1999. This
partnership has allowed CDC to take advantage of the $4 billion annual
pharmaceutical buying power of the VA to analyze the various markets
and then develop unique and very favorable contractual arrangements
for the stockpile program. These contracts provide for the
acquisition of pharmaceuticals and other materiel, inventory rotation
and maintenance, and emergency transport. CDCs
partnership with the VA has also permitted the stockpile program to
access the VAs
prime vendors for pharmaceuticals and medical/surgical supplies under
very favorable terms.
Core Capacities
for State and Local Health Bioterrorism Preparedness and Response
Prior to September 11, CDC was working with partners at
all levels to develop core capacities needed to respond to pubic
health threats and emergencies. CDC has developed specific guidelines
to assist public health agencies in their efforts to build
comprehensive bioterrorism preparedness and response programs. This
collaborative effort engaged federal, state, and local partners in
determining their needs in order to improve their preparedness and
response to bioterrorism. The process enabled health departments to
more effectively target specific improvements to protect the publics
health in the event of a biological or chemical terrorist event, and
provides the framework for ongoing program efforts. The core
capacities effort is dual purpose; while these capacities focus on
bioterrorism events, they are also relevant to naturally occurring
infectious disease outbreaks and natural disasters.
The events of last fall demonstrate that we must move
much more rapidly to expand our capacity to respond to all public
health emergencies. In late January, HHS announced that a total of
$1.1 billion in funding would be provided to states to assist them in
their efforts to prepare for bioterrorism, other infectious disease
outbreaks, and other public health threats and emergencies. On
January 31st, Secretary Thompson sent a letter to the
governor in each state detailing how much of the $1.1 billion his or
her state would receive to allow them to initiate and expand planning
and building of the public health systems necessary to respond. State
proposals outlining these plans are due to HHS by April 15th.
The funds will be made available through cooperative agreements with
State health departmentsand
several large metropolitan area health departmentsto
be awarded by CDC and the Health Resources and Services
Administration, and through contracts awarded by the Office of
Emergency Preparedness with cities for the Metropolitan Medical
Response System Initiative.
The funds are to be used for the development of
comprehensive public health emergency preparedness and response
capabilities; upgrading infectious disease surveillance and
investigation; enhancing the readiness of hospital systems to deal
with large numbers of casualties; expanding public health laboratory
and communications capacities; education and training for public
health personnel, including clinicians, hospital workers, and other
critical public health responders; and improving connectivity between
hospitals and local, city, and state health departments to enhance
disease detection.
CDCs Education and Training
Efforts for Bioterrorism
CDCs
goal in education and training is for the entire public health system
to maintain a public health workforce fully capable of delivering the
Essential Public Health Services during routine and emergency
operations. As one of the
nations largest providers of healthcare, the Department of Veterans
Affairs (VA) is a partner in CDCs efforts. CDC and the VA
collaborate through a number of different training and education
mechanisms, including: the Public Health Training Network (PHTN),
laboratory training activities, and the Association of American
Medical College's (AAMC) bioterrorism initiative "First Contact, First
Response."
Since October 2000, seventy‑nine VA Medical Centers
have participated as satellite downlink sites for PHTN presentations.
In 2001, more than 66,000 health professionals earned continuing
education credits through PHTN programs.
The National Laboratory Training Network (NLTN)
provides clinical, environmental, and public health laboratory
training courses, with six regional offices available to identify
training needs, deliver courses, and evaluate NLTN training programs.
In the last year alone, NLTN delivered more
than 226 courses to an audience of more than 6,200 students. Since
1997, NLTN has trained 359 students from the VA.
In 2000,
CDC established a national system of Centers for Public Health
Preparedness (CPHP) to strengthen state and local workforce capacity
to respond to bioterrorism and to support CDC's prevention programs in
general. The Centers have developed over 180 bioterrorism‑related
training programs, short courses, seminars, public meetings, media
interviews, and national satellite broadcasts to address local and
regional concerns preparedness concerns.
The AAMCs
educational plan has been designed with CDC to address the
preparedness of the workforce, in both the near and distant futures,
by including specific educational experiences for medical students,
resident physicians and practicing physicians.
Specifically, regional
medicine-public health education centers will be established to
facilitate preparedness education activities and foster collaboration
between medical schools and state/local public health agencies.
CDC is committed to collaborate with the VA, DoD, FEMA,
FDA and other federal partners, State and local governmental agencies
as well as medical societies, national professional organizations in
implementing the Centers for Preparedness and other education and
training programs targeting clinicians and other public health and
healthcare professionals.
Challenges
As we continue to strengthen our homeland security and,
among other things, our ability to deal with bioterrorism, it is our
hope that we will not face bioterrorist attacks that impose mass
casualties on our cities. We must nevertheless plan for it, so that,
if the unthinkable should occur, we are prepared to deal with it.
Thus, for example, the Administration is seeking legislation that
would amend the Public Health Service Act to allow the President, when
he determines that the public health so requires, to authorize the
U.S. armed forces to provide support to the Secretary of Health and
Human Services in the exercise of the Secretarys
statutory quarantine-related powers.
CDC has been addressing issues of detection,
epidemiologic investigation, diagnostics, and enhanced infrastructure
and communications as part of its overall bioterrorism preparedness
strategies. CDC will continue to work with partners to address
challenges such as improving coordination among other federal agencies
during a response and understanding the necessary relationship needed
between conducting a criminal investigation versus an epidemiologic
case investigation. These issues, as well as overall preparedness
planning at federal, state, and local levels, require additional
action to ensure that the nation is fully prepared to respond to acts
of biological and chemical terrorism.
Disease experts at CDC are working with partners at
other federal agencies and in state and local health departments to
develop strategies to prevent the spread of disease during and after
bioterrorist attacks. Specific components include (1) creating
protocols for review by the FDA for immunizing at-risk populations
subject to the availability of suitable vaccines; (2) isolating large
numbers of exposed individuals when there is risk that the disease can
be spread from person to person; (3) reducing occupational exposures;
(4) assessing methods of safeguarding food and water from deliberate
contamination; and (5) exploring ways to improve linkages between
animal and human disease surveillance networks since threat agents
that affect both humans and animals may first be detected in animals.
Conclusion
In conclusion, CDC is committed to working with other
federal agencies and partners, as well as state and local public health
departments to ensure the health and medical care of our citizens. We
have made substantial progress to date in enhancing the nations
capability to prepare for and respond to a bioterrorist event. The best
public health strategy to protect the health of civilians against a
biological attack is the development, organization, and enhancement of
public health prevention systems and tools. Priorities include
strengthened public health laboratory capacity, increased surveillance
and outbreak investigation capacity, and health communications,
education, and training at the federal, state, and local levels. Not
only will this approach ensure that we are prepared for deliberate
bioterrorist threats, but it will also ensure that we will be able to
recognize and control naturally occurring new or re-emerging infectious
diseases. A strong and flexible public health infrastructure is the
best defense against any disease outbreak.
Thank you very much for your attention. I will be happy
to answer any questions you may have.
