Accueil General information: Malaria. Malaria: General information. Malaria is a disease caused by the parasite Plasmodium , which is transmitted by the bite of an infected mosquito. Only the Anopheles genus of the mosquito can transmit Malaria. To diagnose malaria, blood slides are examined under a microscope, where the parasite is seen inside red blood cells.
Rapid diagnostic test kits RDTs are used for diagnosing malaria in remote areas where microscopes cannot be used. Plasmodium vivax or P. Of these, infection with P.
Chloroquine was the treatment of choice for malaria and is still followed in most countries for treatment of P. Vivax , but P. As a result, Artemisinin-based combination therapy is now presently advised as the primary treatment for malaria. Among preventive measures, the use of insecticide treated nets at home and indoor residual spraying of insecticides are recommended for malaria. These precautions act by decreasing exposure to bites of infected mosquitoes.
Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected mosquitoes. There were million cases of malaria in , causing nearly , deaths, mostly among African children. Approximately half of the world's population is at risk of malaria, particularly those living in lower-income countries. In the Americas million people are considered to living in areas at risk of malaria.
Travellers from malaria-free areas to disease "hot spots" are especially vulnerable to the disease. Malaria takes an economic toll - cutting economic growth rates by as much as 1.
Travellers from malaria-free regions, with little or no immunity, who go to areas with high disease rates are very vulnerable. Non-immune pregnant women are at high risk of malaria. 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 million people are infected with malaria, and more than , 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.

When the parasites mature, they leave the liver and infect red blood cells. Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites. Because the parasites that cause malaria affect red blood cells, people can also catch malaria from exposure to infected blood, including:.
The greatest risk factor for developing malaria is to live in or to visit areas where the disease is common.
