Carrier
A
carrier
is
a
special
type
of
reservoir.
Generally
a
carrier
is
one
that
has
recovered
from
the
disease
but
continues
to
shed
the
disease
agents.
Thus
persons
who
have
recovered
from
typhoid
fever
or
amoebiasis
are
usually
carriers
for
many
weeks
after
disappearance
of
the
disease
symptoms. Their
faces
may
spread
the
disease
through
contaminated
food
or
water.
Animals
may
also
he
reservoirs
of
disease.
Domestic
house
cats
without
showing
symptom
may
transmit
toxoplasmosis,
caused
by
Toxoplasma
gondii
to
humans.
