Plasmodium falciparum is a P. falciparum is therefore regarded as the deadliest parasite in humans. It is also associated with the development of blood cancer ( Plasmodium falciparum Macrogametocyte (left) and microgametocyte (right) of P. falciparum Domain: Clade: Clade: Clade: Clade: Phylum: Class: Order: Family: Genus: Plasmodium Species: ( • Oscillaria malariae Laveran, 1881 • Plasmodium malariae Marchiafava and Celli, 1885 • Laverania malariae Feletti and Grassi, 1890 • Ematozoo falciforme Antolisei and Angelini, 1890 • Haemamoeba immaculata Grassi, 1891 • Haemamoeba laverani Labbe, 1894 • Haematozoon falciforme Thayer and Hewetson, 1895 • Haematozoon falciparum Welch, 1897 • Haemosporidium sedecimanae Lewkowicz, 1897 • Haemosporidium undecimanae Lewkowicz, 1897 • Haemosporidium vigesimotertianae Lewkowicz, 1897 The species originated from the malarial parasite Oscillaria malariae.

Overview Malaria is a disease caused by a parasite. The parasite is spread to humans through the bites of infected mosquitoes. People who have malaria usually feel very sick with a high fever and shaking chills. While the disease is uncommon in temperate climates, malaria is still common in tropical and subtropical countries. Each year nearly 290 million people are infected with malaria, and more than 400,000 people die of the disease. To reduce malaria infections, world health programs distribute preventive drugs and insecticide-treated bed nets to protect people from mosquito bites. The World Health Organization has recommended a malaria vaccine for use in children who live in countries with high numbers of malaria cases. Protective clothing, bed nets and insecticides can protect you while traveling. You also can take preventive medicine before, during and after a trip to a high-risk area. Many malaria parasites have developed resistance to common drugs used to treat the disease. Symptoms Signs and symptoms of malaria may include: • Fever • Chills • General feeling of discomfort • Headache • Nausea and vomiting • Diarrhea • Abdominal pain • Muscle or joint pain • Fatigue • Rapid breathing • Rapid heart rate • Cough Some 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 within a few ...

What Are the Different Types of Malaria Parasites? Five species of Plasmodium (single-celled parasites) can infect humans and cause illness: • Plasmodium falciparum (or P. falciparum) • Plasmodium malariae (or P. malariae) • Plasmodium vivax (or P. vivax) • Plasmodium ovale (or P. ovale) • Plasmodium knowlesi (or P. knowlesi) Falciparum malaria is potentially life-threatening. Patients with severe falciparum malaria may develop liver and kidney failure, convulsions, and coma. Although occasionally severe, infections with P. vivax and P. ovale generally cause less serious illness, but the parasites can remain dormant in the liver for many months, causing a reappearance of symptoms months or even years later. Clinical Trials Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials. Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.

What is malaria? Malaria is a life-threatening disease. It’s typically transmitted through the bite of an infected Anopheles mosquito. Infected mosquitoes carry the Plasmodium parasite. When this mosquito bites you, the parasite is released into your bloodstream. Once the parasites are inside your body, they travel to the Within 48 to 72 hours, the parasites inside the red blood cells multiply, causing the infected cells to burst open. The parasites continue to infect red blood cells, resulting in symptoms that occur in cycles that last two to three days at a time. Malaria is typically found in tropical and subtropical climates where the parasites can live. The In the United States, the Centers for Disease Control and Prevention (CDC) report Read more: Learn about the relationship between cytopenia and malaria » Malaria can occur if a mosquito infected with the Plasmodium parasite bites you. There are four kinds of malaria parasites that can infect humans: Plasmodium vivax, P. ovale, P. malariae, and P. falciparum. P. falciparum causes a more severe form of the disease and those who contract this form of malaria have a higher risk of death. An infected mother can also pass the disease to her baby at birth. This is known as congenital malaria. Malaria is transmitted by blood, so it can also be transmitted through: • an organ transplant • a • use of shared needles or syringes The symptoms of malaria typically develop within 10 days to 4 weeks following the infection. In some...
