In nineteen eighty-seven health and medical officials are shocked to learn that
people are dying from inside the influenza virus known as H5N1.
It is a virus known to kill birds but has never before been found in people the virus
has mutated and broken through the species we are
here from birds to humans this parts fears of a potentially
devastating global pandemic could kill millions of people it is almost certain the global
community will face another influenza pandemic at some three day and time
removers will be able to exclude almost fifty percent of those that we
don't have do end up going from this disease there's
gonna be not just national misconduct or whatever we are preparing for subpoenaed them reopened
or everything for excellence fame from around the world
a flu pandemic occurs when the new influenza virus emerges of virus for which
people have little or no immunity and no available vaccine the disease
spreads easily from person to person causes serious illness and can quickly
sweep across the country and around the world we the influenza pandemic of nineteen
eighty the so-called spanish flu remains the most deadly in recent
history it killed an estimated twenty two forty
million people there've been several influenza pandemic
since then but none has deadline hong kong nineteen ninety-seven officials are not taking
any chances they respond to the outbreak of h five
and one etienne influenza by calling one point five million birds
in three days there are no more immediate cases of
direct transmission of the disease from birds to humans but the danger has not passed in
early two thousand three to more human cases of age five and one come to light
in hong kong then another in china throughout two thousand three the virus
spreads to poultry in korea and vietnam the rate of human and animal infection
speaks in two thousand six with a slight decline in two thousand
seven
more than ten years have passed since the first human cases came to light which
side is still don't know if each five and one will be the virus that ignites
the next pandemic because many of the telltale characteristics it has passed from birds to
humans we have no immunity to work the virus kills quickly and efficiently it has not acquire
the ability to pass easily from person to person we've seen instances
where there has been transmission from karen too scared for
a child one family member or a brother caring from not for another brother but then it gets
stocks the transmission justice inefficient despite advances in science viruses like h
five n one are still mysterious viruses do not eat they do not
produce waste they do not reproduce independently unlike bacteria they
are not what we think of has holy living organisms of virus is more like a chemical
equation that has one function to replicate itself actually takeover the living cell and
use different parts of that's out to make copies of
themselves trying lol has raised a concern not only in public
health button bernard goetz because the theory is bit personal human could be confronted
with an avian influenza h five parts and the human
virus at the same time this is an infection of a single cell with infection but you might
get is the two parts of the students ever man join together to become
a hard parts are produced offered her heart that have genes
of both the age five and kings of the human body parts and offered money com
than expanded apt if h five n one mutates and becomes a
pandemic virus experts say the key to limiting the
death toll will be better detection and containment of affected population but this will not be
easy today people can move across town in minutes and around the globe in a matter of
hours marcy reinvent reviewer is not all of us
are going to stop it completely rather that we will slow the spread and decrease the number
of people who are affected by the disease and thereby mitigate
the impact of the potential worldwide pandemic doctors under
wagon says once the exact viruses identified it will take five months
to fully ramp up production of the vaccine humans don't respond faring well
too vaccines that have been meaning it's had ten years to evolve and so there are different
subgroups so we knew that seemed quite dealing that will cover all these different
subgroups pandemic influenza presents a global challenge so cooperation and coordination
between nations is belmont experts describe pandemic
influenza as a confluence of disciplines the nexus where animal health
public-health and international relations meat to face a common thread so here it is
a product where you work borrowers because there are sisters falsely
immunologists history the responsive hoover or the human for
the past as well as back self-esteem work on pretty vaccines you propose to cut understand
disease at the heart of hearts for it as well as cross
brought her sister medicine who works with the poultry cases and physicians
nurses etc et-cetera to work on the human side of those into propaganda
is much easier to control these diseases in animals and prevent the
spread into the human population as opposed to just waiting until the human population
becomes infected artist there but they've jadi information page you know at this point
and sea and air reporting system is very important weekend
extended information exchanges someone might be dead laboratory assistant
strongly abt apart of something one of the challenges of controlling
avian influenza in developing nations is the structure of the poultry industry in more
developed countries poultry production is a commercial endeavor but takes
place in highly controlled unregulated biosecurity units if a problem
is found it is called and contained quickly in the developing world
poultry production often takes place in a village
setting with backyard flocks for individual families here people live close
to the wire and the animals that sustain them this
is a concern because most cases of etienne influenza infection in humans are caused by
directing prolonged contact with infected poultry their feces
respiratory secretions people and poultry often share the same
living space making this kind of contact more likely consuming undercooked meat or blood
products from six birds can also cause infection even in densely populated cities people often
prefer live birds to processed meat poultry are moved from place
to place interacting constantly with people but that's
is slowly changing what cases asian countries now instead of a library
c for that's been killed but not necessarily home cut up into parts like it is in the
united states to myself hold that that feathers taking off for the don't
have towards the white house health officials say these changes
reduce the likelihood that birds infected with age five and one will make people sick
but they do not fully eliminates the problem the poultry industry is changing in
many parts of the world but that change is far
from complete
