Malaria -
The
disease
was
described
as
early
as
5th
century
,B.C.
There
are
four
recognised
species
of
Plasmodium,
that
are
related
to
malaria:
P.
vivax
,p.ovale,
P.
malariae
and
P.
falciparum,
all
transmitted
by
female
Anopheles
mosquito.
This
insect
consumes
human
blood
to
acquire
a
component
for
the
production
of
her
eggs.
The
parasite
has
a
very
complex
life
cycle.
It
takes
place
partly
in
mosquito
and
partly
in
the
human
blood.
The
parasite
enters
the
blood
stream
in
the
sporozite
form
and
immediately
invades
the
liver,
where
it
is
very
difficult
to
treat.
After
several
hours,
many
of
the
merozites
emerge
and
penetrate
the
red
blood
cells. Thousands
of
RBCs
rupture
simultaneously
and
release
tens
of
thousands
of
new
parasites.
At
this
Point,
the
victim
suffers
a
malaria
attack.
There
is
severe
cold,
temperature
rises
rapidly
to
104°F
-
1O6°p
and
there
is
severe
headache
with
mild
delirium.
After
next
two
or
three
hours,
massive
perspiration
ends
the
hot
stage.
