Malaria: What is it?
Transcript of Malaria: What is it?
7) How is malaria diagnosed?
Malaria is diagnosed by a blood test to check for parasites. 4)Who is at risk for malaria? 5)What are the signs and
symptoms of malaria? People with malaria often experience fever, chills, and flu-like illness.
Nausea and vomiting
Jaundice (yellowing of the
skin or whites of the eyes)
People with malaria typically have cycles of chills, fever, and sweating that recur every 1, 2, or 3 days. The attack of the malaria parasites on the person's red blood cells makes the person's temperature rise and the person feel hot. The subsequent bursting of red blood cells makes the person feel cold and have hard, shaking chills. Nausea, vomiting, and diarrhea often go along with the fever. The destruction of red blood cells can also cause jaundice (yellowing of the skin or whites of the eyes) and anemia.
6)What are the complications
of malaria? 8) What is the treatment
for malaria? 2) How common is malaria? 3) How do people get malaria?
9) How can malaria
be prevented? 10) Where can I get
more information? Treatment of malaria depends on many factors including disease severity, the species of malaria parasite causing the infection and the part of the world in which the infection was acquired. The latter 2 characteristics help determine the probability that the organism is resistant to certain antimalarial drugs. Additional factors such as age, weight, and pregnancy status may limit the available options for malaria treatment. Malaria caused by Plasmodium falciparum can cause kidney or liver failure, coma, and death. Although infections with other malaria parasites cause less serious illness, parasites can remain inactive in the liver and cause a reappearance of symptoms months or even years later. Anyone who lives in or travels to a country where there are malaria-infected people and mosquitoes is at risk. Worldwide, an estimated 200 million to 300 million malaria infections occur each year, with 2 million to 3 million deaths. Most deaths are from infection with Plasmodium falciparum.
About 1,200 cases of malaria are diagnosed in the United States each year. Most are in persons entering the country for the first time or returning from foreign travel. A very small number of cases are the result of direct transmission involving mosquitoes that live in the United States. Most of these have occurred in Mexican farm workers living in California in poor conditions.
No vaccine against malaria is available. Travelers can protect themselves by using anti-mosquito measures and by taking drugs to prevent malaria.
1. Avoid mosquito bites -- Avoiding the bites of Anopheles mosquitoes is the best way to prevent infection. Because Anopheles mosquitoes feed at night, malaria transmission happens mainly between dusk and dawn. Travelers should take steps to reduce contact with mosquitoes both when outdoors and inside, especially during these hours.
When outside: Wear long-sleeved clothing and long pants. For extra protection, treat clothing with the insecticide permethrin.
Use insect repellent on exposed skin.
Use a bednet when sleeping in a room that is not screened or air conditioned.
2. Take anti-malaria drugs -- When traveling to an area known to have malaria, discuss your travel plans with a doctor well before departure. Medicines to prevent malaria are usually prescribed for persons traveling to areas where malaria is common.
3. Seek medical help in case of illness -- Symptoms of malaria can be mild. Travelers should suspect malaria if they experience an unexplained fever while in or after returning from an area where malaria is common.

http://www.cdc.gov/malaria/ A person gets malaria from the bite of an infected female mosquito. The mosquito bite injects young forms of the malaria parasite into the person's blood. The parasites travel through the person's bloodstream to the liver, where they grow to their next stage of development. In 6 to 9 days, the parasites leave the liver and enter the bloodstream again. They invade the red blood cells, finish growing, and begin to multiply quickly. The number of parasites increases until the red blood cells burst, releasing thousands of parasites into the person's bloodstream. The parasites attack other red blood cells, and the cycle of infection continues, causing the common signs and symptoms of malaria.
When a non-infected mosquito bites an infected person, the mosquito sucks up parasites from the person's blood. The mosquito is then infected with the malaria parasites. The parasites go through several stages of growth in the mosquito. When the mosquito bites someone else, that person will become infected with malaria parasites, and the cycle will begin again.
