Is an infection of the blood by Plasmodium parasite that is carried from person to person by mosquitoes. There are four species of malaria parasites that infect man: Plasmodium falciparum, so called ‘malignant tertian fever’, is the most serious disease, Plasmodium vivax, causing a relapsing form of the disease, Plasmodium malariae, and Plasmodium ovale.
A febrile disease caused by infection with Plasmodial parasites, causing periodic attacks of chills, fever and sweating.
An acute, usually chronic, disease caused by protozoa belonging to the genus Plasmodium and transmitted by Anopheles mosquito. It is characterized by intermittent fever, anemia, and debility, and in its acute form, by chills, high fever, and profuse sweating at regular intervals.
A parasitic disease caused by Plasmodium parasites; it is transmitted by mosquitoes.
A disease caused by infection of the red blood cells with one of several types of protozoan q.v. parasites of the genus Plasmodium.
A mainly tropical disease caused by a parasite Plasmodium, which enters the body after a bite from the female anopheles mosquito.
Serious infectious illness characterized by recurrent episodes of chills, fever, headache, anemia, muscle ache, and enlarged spleen. It is caused by Plasmodium protozoa transmitted from human to human through the bite of an infected Anopheles mosquito or through blood transfusions or infected hypodermic needles; it is largely confined to tropical and subtropical areas. Treatment is by chloroquine or, in resistant cases, a combination of quinine, sulfonamides, and other drugs. Prevention includes removal of swampy areas where Anopheles mosquitos breed, the use of insecticides and mosquito netting, and the use of antimalarial drugs when travelling in areas where malaria is prevalent.
A febrile illness with malaise, headache, fatigue, and muscular aches due to infection by protozoa from the genus Plasmodium.
A disease caused by Plasmodium protozoa, transmitted to humans by the bite of the Anopheles mosquito or blood from infected donors. Attacks may occur repeatedly, causing fever, chills, sweating, malaise, headache, and muscular pains. The disease is treated with drugs and prevented by elimination of mosquito breeding areas.
A protozoal disease caused by a microscopic, single-celled parasite that is transmitted from person to person by a female Anopheles mosquito. Malaria is caused by infection with one of four different types of parasitic protozoa called plasmodia. Female Anopheles mosquitoes carry an infectious form of this parasite in their saliva. The parasite is transmitted to a person who has been bitten by an infected mosquito, and the parasite enters the person’s bloodstream.
A parasitic disease caused by four species of plasmodium: P falciparum, P. vivax, P. ovale, and P malariae. It causes recurrent episodes of high fever, sometimes associated with rigor; enlargement of the spleen is common. P falciparum infection can also be associated with several serious often fatal complications although other species cause chronic disease, death is unusual.
A febrile hemolytic disease caused by infection with protozoa of the genus Plasmodium. Worldwide malaria is responsible for about 3 million deaths a year. There are four species of malaria: the “benign” malarias: P. vivax, P. ovale, and P. malariae; and the potentially “malignant” malaria, P. falciparum. Each has its own geographic distribution, incubation period, symptoms, and treatment.
Parasitic condition due to the development and multiplication of hematozygotes of the genus Plasmodium.
A grave ailment commonly found in tropical regions, this condition is instigated by parasites and gives rise to intense fever, occasionally leading to complications that impact the kidneys, liver, brain, and blood. The Anopheles mosquito serves as the vector for its transmission, and in severe cases, it can result in fatality.
A severe illness caused by the protozoa known as plasmodia. This infection is transmitted through the bite of Anopheles mosquitoes and is common in tropical regions. Malaria leads to intense fever and can result in deadly complications impacting the kidneys, liver, brain, and blood.
Four types of plasmodia are responsible for malaria: Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. When an infected mosquito bites a person, these plasmodia enter the bloodstream. They then target the liver and red blood cells, multiplying within them. Eventually, the red cells burst, dispersing the new parasites. While some of these newly-released parasites go on to infect additional red cells, others mature into forms that can be picked up by other mosquitoes. The falciparum type affects a greater number of red cells, leading to more severe infections, with the majority of cases found in Africa.
Malaria symptoms encompass fever, chills, and trembling. Individuals may also experience intense headaches, a feeling of discomfort, and nausea. Typically, the fever appears cyclically, presenting every two days with vivax and ovale infections, or every three days in the case of malariae infections.
Falciparum malaria can lead to death in just a matter of days. The infected red blood cells tend to clump together, obstructing blood flow in crucial organs. This can cause an enlarged spleen and potentially impact the brain, resulting in comas and seizures. The breakdown of red blood cells can result in haemolytic anaemia. Additionally, complications like kidney failure and jaundice are common.
To identify the parasites, a blood sample is examined. For treating Falciparum malaria, options include quinine, mefloquine, a combination of proguanil and atovaquone, or artemether combined with lumefantrine. For types other than falciparum, chloroquine is typically prescribed. For those with vivax or ovale malaria, primaquine is also given to eliminate parasites from the liver. In extreme cases, a blood transfusion might be required.
Individuals residing in or traveling to areas with malaria risk should take measures to prevent mosquito bites. This includes wearing long sleeves and pants, applying insect repellent, and using mosquito nets. Additionally, travelers should begin taking antimalarial medications up to three weeks prior to their trip and continue for one to four weeks after leaving, depending on the specific medication. It’s essential to consult with a physician for the most current recommendations on drug selection.
An infectious illness characterized by recurring episodes that follow a sequence of fever (hot stage), chills (cold stage), and sweating (sweating stage). This disease is accompanied by an enlarged spleen and the presence of the causative organism in the blood. Multiple species of protozoans from the genus Plasmodium are responsible for this condition, and it is transmitted to humans through the bite of infected mosquitoes, specifically from the Anopheles genus. There are various types of this disease, distinguished by the time intervals between episodes, which are determined by how long it takes the specific species of the organism to develop within the body. Today, prevention and treatment primarily rely on synthetic chemicals, although quinine, the original treatment, is still occasionally employed.
