    Malaria is a disease caused by a parasite. The parasite is transmitted to humans through the bites of infected mosquitoes. People who have malaria usually feel very sick, with a high fever and shaking chills. Each year, approximately 210 million people are infected with malaria, and about 440,000 people die from the disease. Most of the people who die from the disease are young children in Africa.While the disease is uncommon in temperate climates, malaria is still common in tropical and subt...

    A malaria infection is generally characterized by the following signs and symptoms: 1. Fever 2. Chills 3. Headache 4. Nausea and vomiting 5. Muscle pain and fatigueOther signs and symptoms may include: 1. Sweating 2. Chest or abdominal pain 3. CoughSome people who have malaria experience cycles of malaria \\"attacks.\\" An attack usually starts with shivering and chills, followed by a high fever, followed by sweating and a return to normal temperature. Malaria signs and symptoms typically begin w...

    Malaria is caused by a type of microscopic parasite. The parasite is transmitted to humans most commonly through mosquito bites.

    The biggest risk factor for developing malaria is to live in or to visit areas where the disease is common. There are many different varieties of malaria parasites. The variety that causes the most serious complications is most commonly found in: 1. African countries south of the Sahara Desert 2. The Asian subcontinent 3. New Guinea, the Dominican Republic and Haiti

    Malaria can be fatal, particularly malaria caused by the variety of parasite that's common in tropical parts of Africa. The Centers for Disease Control and Prevention estimates that 91 percent of all malaria deaths occur in Africa — most commonly in children under the age of 5.In most cases, malaria deaths are related to one or more serious complications, including: 1. Cerebral malaria. If parasite-filled blood cells block small blood vessels to your brain (cerebral malaria), swelling of your...

    If you live in or are traveling to an area where malaria is common, take steps to avoid mosquito bites. Mosquitoes are most active between dusk and dawn. To protect yourself from mosquito bites, you should: 1. Cover your skin. Wear pants and long-sleeved shirts. 2. Apply insect repellant to skin and clothing. Sprays containing DEET can be used on skin and sprays containing permethrin are safe to apply to clothing. 3. Sleep under a net. Bed nets, particularly those treated with insecticide, he...

    Malaria is a parasitic disease that involves high fevers, shaking chills, flu-like symptoms, and anemia.

    Quartan malaria; Falciparum malaria; Biduoterian fever; Blackwater fever; Tertian malaria; Plasmodium

    Malaria is caused by a parasite. It is passed to humans by the bite of infected anopheles mosquitoes. After infection, the parasites (called sporozoites) travel through the bloodstream to the liver. There, they mature and release another form of parasites, called merozoites. The parasites enter the bloodstream and infect red blood cells. The parasites multiply inside the red blood cells. The cells then break open within 48 to 72 hours and infect more red blood cells. The first symptoms usually occur 10 days to 4 weeks after infection, though they can appear as early as 8 days or as long as a year after infection. The symptoms occur in cycles of 48 to 72 hours. Most symptoms are caused by: 1. The release of merozoites into the bloodstream 2. Anemia resulting from the destruction of the red blood cells 3. Large amounts of free hemoglobinbeing released into circulation after red blood cells break open Malaria can also be transmitted from a mother to her unborn baby (congenitally) and b...

    Symptoms include: 1. Anemia (condition in which the body doesn’t have enough healthy red blood cells) 2. Bloody stools 3. Chills, fever, sweating 4. Coma 5. Convulsions 6. Headache 7. Jaundice 8. Muscle pain 9. Nausea and vomiting

    During a physical examination, the health care provider may find an enlarged liver or enlarged spleen. Tests that are done include: 1. Rapid diagnostic tests, which are becoming more common because they are easier to use and require less training by laboratory technicians 2. Malaria blood smears taken at 6 to 12 hour intervals to confirm the diagnosis 3. A complete blood count(CBC) will identify anemia if it is present

    Malaria, especially falciparum malaria, is a medical emergency that requires a hospital stay. Chloroquine is often used as an anti-malarial medicine. But chloroquine-resistant infections are common in some parts of the world. Possible treatments for chloroquine-resistant infections include: 1. Artemisinin derivative combinations, including artemether and lumefantrine 2. Atovaquone-proguanil 3. Quinine-based regimen, in combination with doxycycline or clindamycin 4. Mefloquine, in combination with artesunate or doxycycline The choice of drug depends, in part, on where you got the infection. Medical care, including fluids through a vein (IV) and other drugs and breathing (respiratory) support may be needed.

    Outcome is expected to be good in most cases of malaria with treatment, but poor in falciparum infection with complications.

    Health problems that may result from malaria include: 1. Brain infection (cerebritis) 2. Destruction of blood cells (hemolytic anemia) 3. Kidney failure 4. Liver failure 5. Meningitis 6. Respiratory failure from fluid in the lungs (pulmonary edema) 7. Rupture of the spleen leading to massive internal bleeding (hemorrhage)

    Call your health care provider if you develop fever and headache after visiting any foreign country.

    Most people who live in areas where malaria is common have developed some immunityto the disease. Visitors will not have immunity and should take preventive medications. It is important to see your health care provider well before your trip. This is because treatment may need to begin as long as 2 weeks before travel to the area, and continue for a month after you leave the area. Most travelers from the United States who contract malaria fail to take the right precautions. The types of anti-malarial drugs prescribed depend on the area you visit. Travelers to South America, Africa, the Indian subcontinent, Asia, and the South Pacific should take one of the following drugs: mefloquine, doxycycline, chloroquine, hydroxychloroquine or atovaquone-proguanil. Even pregnant women should consider taking preventive drugs because the risk to the fetus from the drug is less than the risk of catching this infection. Chloroquine has been the drug of choice for protecting against malaria. But beca...

    2 days ago · Where malaria is common, carrying a single sickle cell allele (trait) confers a heterozygote advantage; humans with one of the two alleles of sickle cell disease show less severe symptoms when infected with malaria. This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations.
