Issue brief: strengthening national health systems' capacity to respond to future global pandemics
Publication year: 2013
Effective pandemic governance is more important now than
ever as pandemic risk factors like urbanization, the
hypermobility of persons, trans-border trade, rapid
population growth and changes to the environment and
food systems all increase in tandem with the demands of
globalization.(1) These transformative global shifts have
fundamentally changed the way pathogens are spread
around the world.(2) The World Health Organization
(WHO) estimates that newly emerging infectious disease
outbreaks in one country are now only hours away from
affecting many others.(3) Pandemics previously spread over
years (e.g., bubonic plague in the 14th century), months
(e.g., cholera epidemics in 19th century) or weeks (e.g.,
Spanish influenza of 1918-1919), but in today’s globalized
world, Severe Acute Respiratory Syndrome (SARS) took
only 17 hours to spread half-way around the world from
China to Canada. Future disease outbreaks are expected to
take similarly short periods before they affect multiple
countries across geographically distinct regions.(3) The
current outbreak of H7N9 bird influenza in China (which
spreads more easily from infected fowl to humans than the
H5N1 strain did in 2003, according to Dr. Keiji Fukuda,
WHO’s top influenza expert) is a stark reminder that the
threat of a pandemic exists as an imminent threat to human
health and international security.(4) Of notable concern is
the fact that more than 30 unexpected outbreaks of
previously unknown pathogens and re-emerging diseases
were observed in the past two decades alone.(2) Although
the great majority of new and re-emerging diseases have not
caused pandemics, national health systems that can respond
adequately to pandemic threats are fundamental to
controlling pandemic-prone local disease outbreaks within a
country or a region
