  The
 Communicable
 Disease
 Outbreak
 of
 Avian
 Influenza

 Communicable
 diseases
 account
 for
 approximately
 1/4th
 of
 worldwide
 mortality,
  contributing
 to
 more
 than
 15
 million
 deaths
 each
 year
 (Kierny,
 Exclor,
 and
 Girard,
  2004).
 
 There
 have
 been
 three
 pandemics
 of
 Avian
 Influenza
 in
 the
 last
 century-­‐ 1918,
 1957,
 and
 1968.
 
 There
 have
 been
 worldwide
 outbreaks
 of
 Avian
 Influenza
  among
 poultry
 over
 the
 years.
 
 It
 is
 not
 easily
 passed
 from
 birds
 to
 humans.
 The
 first
  outbreak
 of
 Avian
 Influenza
 A
 (H5N1)
 in
 humans
 was
 in
 Hong
 Kong
 in
 1997.
 
 In
  March
 through
 May
 of
 1997,
 a
 die
 off
 of
 poultry
 was
 reported,
 due
 to
 a
 highly
  virulent
 disease.
 
 Research
 revealed
 it
 was
 from
 Avian
 Influenza
 (H5N1).
 In
 May,
 a
  three-­‐year-­‐old
 boy
 died
 of
 “complications”
 from
 H5N1.
 
 In
 early
 December,
 three
  more
 deaths
 occurred
 as
 a
 result
 of
 Avian
 Influenza
 infection,
 ages
 60,
 54
 and
 13.
 
  Five
 more
 cases
 involving
 varying
 ages
 were
 confirmed
 by
 mid
 December.
 
 
 A
 two
  and
 three
 year
 old
 were
 cousins
 to
 a
 five
 year
 old
 who
 became
 ill.
 There
 were
 18
  confirmed
 cases
 and
 8
 deaths
 related
 to
 the
 H5N1
 strain
 of
 influenza
 by
 the
 end
 of
  the
 year.
 
 The
 age
 range
 was
 one
 to
 sixty.
 The
 infection
 was
 acquired
 by
 humans
  directly
 from
 chickens.
 
 According
 to
 Butcher
 and
 Miles
 (2004),
 on
 December
 28,
  1997,
 the
 Hong
 Kong
 Department
 of
 Agriculture
 Fisheries
 ordered
 a
 slaughter
 of
 all
  chickens
 for
 a
 total
 of
 1.3
 million
 chickens.
 Exports
 from
 Mainland
 China
 were
  halted
 temporarily.
  A2-­‐
 The
 Epidemiological
 Indicators
 Associated
 with
 Avian
 Influenza
 
 
 
 
 
 Since
 the
 China
 outbreak
 of
 avian
 influenza
 H5N1,
 the
 virus
 has
 become
 endemic
  in
 Asia,
 and
 has
 caused
 outbreaks
 in
 Europe
 and
 Africa.
 Despite
 detailed
 study,
 little
  is
 known
 about
 the
 epidemiology
 of
 the
 virus.
