WHO prepares defenses against flu pandemic threat
06 March 2006
GENEVA (Reuters) - The global spread of bird flu is unprecedented
and the threat of a human pandemic will not go away, but the world is
not totally defenseless, the World Health Organization (WHO) said on Monday.
Speaking at the start of a three-day meeting of experts called to sharpen
the global response to any human outbreak, the WHO's top influenza official
said the first thing would be to try to stamp it out before it really
took hold.
If that failed, the next move would be to attempt to curtail its spread
and avoid the high death toll and economic devastation that a full blown
pandemic would bring, said Margaret Chan. "When a notoriously unpredictable
virus like the influenza virus is given unprecedented opportunities, we
must be prepared to see some surprises," she said in opening remarks to
the meeting at the WHO headquarters in Geneva. "But we are not without
defenses, if we act collectively right now," she added. Some 30 epidemiologists,
virologists, and laboratory experts will take part in the talks, along
with health officials from affected countries. The aim is to further hone
the WHO's draft "pandemic containment strategy", which calls for using
quarantines and Swiss firm Roche's antiviral Tamiflu
in the frontline against the threat.
H5N1 has killed birds in more than 30 countries stretching from South
Korea to France and into Nigeria. It has spread to 15 new countries in
the past month and infected 174 people since 2003, killing 94 of them.
"Events in recent weeks justify our concern," said Chan. Scientists say
the deadly virus is mutating steadily and may eventually acquire the changes
it needs to be easily transmitted from human to human. Because people
lack any immunity to it, it could sweep the world in a matter of weeks
or months, killing millions and bringing economies to their knees. Even
if a pandemic cannot be stopped, public health interventions such as quarantines
might buy time to allow countries to tighten their control measures, the
WHO says.
