Dracunculiasis (guinea worm disease).
[dracunculiasis]
Dracunculiasis
(
guinea
worm
disease
)
is
a
parasitic
disease
that
is
limited
to
remote
,
rural
villages
in
13
sub-
Saharan
African
countries
that
do
not
have
access
to
safe
drinking
water
.
It
is
one
the
next
diseases
targeted
for
eradication
by
the
World
Health
Organization
.
Guinea
worm
disease
is
transmitted
by
drinking
water
containing
copepods
(
water
fleas
)
that
are
infected
with
Dracunculiasis
medinensis
larvae
.
One
year
after
human
ingestion
of
infected
water
a
female
adult
worm
emerges
,
typically
from
a
lower
extremity
,
producing
painful
ulcers
that
can
impair
mobility
for
up
to
several
weeks
.
This
disease
occurs
annually
when
agricultural
activities
are
at
their
peak
.
Large
proportions
of
economically
productive
individuals
of
a
village
are
usually
affected
simultaneously
,
resulting
in
decreased
agricultural
productivity
and
economic
hardship
.
Eradication
of
guinea
worm
disease
depends
on
prevention
,
as
there
is
no
effective
treatment
or
vaccine
.
Since
1986
,
there
has
been
a
98
%
reduction
in
guinea
worm
disease
worldwide
,
achieved
primarily
through
community-based
programs
.
These
programs
have
educated
local
populations
on
how
to
filter
drinking
water
to
remove
the
parasite
and
how
to
prevent
those
with
ulcers
from
infecting
drinking-water
sources
.
Complete
eradication
will
require
sustained
high
-level
political
,
financial
and
community
support
.
