Infectious diseases know no borders
• The flat, hot and crowded world.
– Jet travel removes the temporal and
geographic barriers
– Increased population density
– Environmental changes may promote
increased vector range and disease
transmission
Office of the
Vice Chancellor for RESEARCH
Infectious diseases know no borders
• Our actions, and the inherent properties of
our microbial enemies, guarantee new
disease threats.
– Expansion and encroachment lead to
exposures to previously unrecognized microbes
– Microbes are evolution in motion—constantly
changing their genetic makeup through
mutation to expand their host range, and resist
therapies.
Office of the
Vice Chancellor for RESEARCH
Under Siege--Biosecurity
• International public health infrastructure.
• Incentives to produce new vaccines and
therapeutics for existing and emerging
diseases.
• Support for basic and applied research on
these biological threats.

Vice Chancellor for RESEARCH
Infectious diseases know no borders
• .
Wisconsin, Illinois, Indiana, Kansas,
Missouri, and Ohio with cases.
72 suspected, 37 confirmed.

US Research Responds
• Why did we see such low morbidity and
mortality with the monkeypox outbreak?
– Virus was from W. Africa—lacks two key
genes found in the more virulent Central
African strain—clues to how we fight off these
viruses.
– Help us understand and prepare for any
future poxvirus outbreaks.
Office of the
Vice Chancellor for RESEARCH
SARS
• More than 8000 cases and 774 deaths
• Epidemic began in November 2002,
exploded internationally in March 2003.
• Widespread concern and significant
economic impact.
Office of the
Vice Chancellor for RESEARCH
SARS—US Research Responds
• In just three months:
–
–
–
–
–
Virus identified.
Virus completely sequenced.
Natural host probably identified.
Diagnostic tests based on viral sequence developed.
Koch’s postulates fulfilled for SARS-CoV– isolated
virus successfully infected monkeys with development
of SARS-like illness and identification of virus in
pathological specimens.
– Understanding the disease led to some preventive
measures and no further significant outbreaks
reported.
Vice Chancellor for RESEARCH
Office of the
New Threats
• Chikungunya—mutation in virus caused
massive outbreak in Reunion—260,000
cases and 37 cases in the U.S.
• 4 deaths in S. Africa from unknown virus—
now identified as arenavirus.
• Methicillin resistant staphyloccus aureus in
the United States and the world, requires
expensive and more toxic antibiotics.
Office of the
Vice Chancellor for RESEARCH
Global Research Needs for Biosecurity
• Worldwide research into rapid recognition
and identification of new disease threats
• Collaboration on new diagnostics—large
scale sequencing to identify new
pathogens—work between U.S.
researchers and those in other countries.
• Epitomized by SARS effort, but U.S. must
help lead the way.
Office of the
Vice Chancellor for RESEARCH
Global Research Needs for Biosecurity
• Continue to support research into broad
spectrum interventions—therapeutics that
target whole classes of viruses or bacteria.
• Vaccines or drugs that boost the immune
system to provide response against
multiple biologic threats—notion of
controlling infection until specific measures
are available.
Office of the
Vice Chancellor for RESEARCH
Global Research Needs for Biosecurity
• Support research on diseases that could
spread to U.S. but are not present
currently.
– Marburg, Ebola, Dengue, Chikungunya.
• Support research on diseases that are
unlikely to threaten the U.S. but destabilize
developing countries.
– Malaria, cholera,
Office of the
Vice Chancellor for RESEARCH
Global Research Needs for Biosecurity
• Support research on diseases that
threaten all people worldwide
– Influenza, HIV, tuberculosis, drug resistant
bacteria and viruses.
Office of the
Vice Chancellor for RESEARCH
Final Thoughts
• Near misses: SARS, monkeypox
• Ongoing hits:
– HIV (present since ?1900)—did not have the
infrastructure to recognize the disease or
identify the agent before it was too late.
– MRSA—driving increased mortality and cost
in our health system
– Drug resistant TB—extensively drug resistant
TB
Office of the
Vice Chancellor for RESEARCH
Final Thoughts
• What is next?
– While it does not guarantee success, shame on us if
we do not make every effort to be prepared for the
next major threat.
• Preparation means
– Global collaborative research on basic mechanisms
of infectious diseases and countermeasures
– Support for a worldwide public health infrastructure
– Incentives to develop the next generation of vaccines
and therapeutics.
Office of the
Vice Chancellor for RESEARCH
Final Thoughts
• Who does this (federal agencies) ?
– NIH
– CDC
– PMI (USAID, HHS, CDC, State, White House)
– Others (DOD, DHS)
• How should it be done?
– Experts identifying major target themes
– Peer reviewed proposals
Office of the
Vice Chancellor for RESEARCH
Thanks
• Paul Rogers—inspiration for how each of
us can make a difference in global health.
• NIH—the backbone of biomedical
research and a key to the discoveries that
will address these threats.
• You
