MALARIA

2. MALARIA
Malaria is caused by a parasite
called Plasmodium, which is In the human body, the
transmitted via the bites of parasites multiply in the liver,
infected mosquitoes. and then infect red blood cells.
Usually, people get malaria by
being bitten by an infective
female Anopheles mosquito.
Only Anopheles mosquitoes
can transmit malaria and they
must have been infected
through a previous blood meal
taken on an infected person. When a mosquito bites an
infected person, a small
amount of blood is taken in
which contains microscopic
malaria parasites
About 1 week later, when the
mosquito takes its next blood

syringes contaminated with
blood.

3. INFECTIOUS OR UNINFECTIOUS
 Malaria is not infectious it can only
be passed on by parasites. When
the mosquito bites you it will take
some blood. If the mosquito has the
plasmodium parasite in it, the blood
from its last meal, will get infected.
The next person it bites will receive
the infected blood and infect them
with malaria

4. WHERE DOES MALARIA
COMMONLY OCCUR
 Malaria commonly occurs in Africa, Asia,
South America, Central America,
Southern Mexico, Caribbean, Europe and
North America. The most common place
it occurs is Sub-Saharan Africa. They have
many Plasmodium falciparum's which is
the most dangerous species, of four, that
causes malaria. Plasmodium falciparum
is a parasite.

5. MALARIA SYMPTOMS
 Symptoms of malaria may include fever,
chills, vomiting, diarrhoea, cough,
stomach, pain and muscular aches and
weakness.
 If infected with the malaria parasite,
Plasmodium results in the most severe
form of malaria and if left untreated, it
can cause serous illnesses. Like seizures,
mental confusion, kidney failure, coma
and death.

6. WHAT CAUSES MALARIA
 Humans develop malaria when infected
with one of the four protozoans from
Plasmodium. A protozoan is a single
celled organism. Plasmodium is a
scientific name for a parasite.

7. IS MALARIA SPREAD BY
VECTORS
 Malaria is spread by vectors. A vector is a
carrier In malaria a mosquito serves as the
vector that carries and transfers the infectious
agent (Plasmodium), injecting it with a bite.

8. HOW CAN MALARIA BE
TREATED
 Malaria is treated with a class of
drugs called antimalarial.
Antimalarial drugs are designed
to attack the parasites that cause
malaria, preventing them from
spreading while also killing them
off so they cant continue causing
infection.

9. HOW CAN MALARIA BE PREVENTED
 Malaria can be treated by:
 Be aware of the places that are malaria risk zones,
the main symptoms and how long it takes for
symptoms to start.
 If prescribed, take anti-malarial medicines strictly
as directed. Anti malarial medicines are not 100%
 Immediately see a doctor and seek treatment if a
fever develops after entering a malaria-risk
zone, and for up to 3 months after leaving the
area.
