Transcript of Malaria presentation

Malaria Organs
Attacked Treatment Prevention Available
Vaccines At this time, there is no approved vaccine for malaria. However, research scientists all over the world are working on developing an effective vaccine. Scientists
have not yet found a vaccine for malaria because there are over 125 types of malaria and they are constantly adapting to live under different conditions. Symptoms of malaria
include fever and flu-like
illness, including shaking
chills, headache, muscle
aches, and tiredness, Nausea,
vomiting, and diarrhea.
Malaria may also cause
jaundice (yellow
coloring of the skin and
eyes) because of the loss of
red blood cells. Symptoms
usually appear between 10 and
15 days after the mosquito bite. In a human, the parasites travel to the liver, reproduce, mature and form clumps. Several days later, the clumps burst and new Plasmodia are released. Each parasite then invades a red blood cell and reproduces again. The infected cells rupture, releasing parasites which then invade other cells Malaria is a mosquito-borne infectious disease.There are more than 125 different species of malaria that infect mammals, birds and reptiles, which indicates an early origin. Historical reports of symptoms that match those of malaria date back to the ancient Egyptians (around 1550 B.C.) and the ancient Greeks (around 413 B.C.).
Because the malaria parasite is found in
red blood cells of an infected person,
malaria can also be transmitted through
blood transfusion, organ transplant, or
the shared use of needles or syringes
contaminated with blood. Malaria may
also be transmitted from a mother to her
unborn infant before or during delivery,
but the most common way that malaria
is transmitted is from mosquito to person. The problem with malaria is the damage to the blood cells which in turn can damage other organs in the body including kidneys, spleen, liver, brain etc. The malaria pathogen is a microscopically small, single-celled parasite named “plasmodium". History of
Disease Reproduction Ways it is

quickly become life-threatening

Wynne 2005 edition volume 13 world book, inc 233 north michigan Avenue Chicago, IL pg. 96 If infected with  Plasmodium
falciparum,(a type of malaria)
if not promptly treated,
may cause kidney failure,
seizures, mental confusion,
coma, and death. Prevention of malaria involves protecting yourself against mosquito bites and taking anti-malarial medicines. But public health officials strongly recommend that young children and pregnant women avoid traveling to areas where malaria is common. Some ways to prevent malaria are:
1.Stay inside when it is dark outside, preferably in a screened or air-conditioned room.
2.Wear protective clothing (long pants and long-sleeved shirts). 3.Use insect repellent with DEET (diethylmetatoluamide). The repellent is available in varying strengths up to 100%. In young children, use a preparation containing less than 24% strength, because too much of the chemical can be absorbed through the skin
Quinine, a drug derived from the bark of the cinchona plant. It has been the main treatment for malaria since the 1600's. Most cases can be cured with quinine and similar synthetic drugs however some varieties of P.falciparum have become resistant to these drugs. which is why creating a vaccine has become very difficult.
