Malaria is a mosquito-borne infectious disease that affects vertebrates. [6][7][3] Human malaria causes symptoms that typically include fever, fatigue, vomiting, and headaches. [1][8] In severe cases, it can cause jaundice, seizures, coma, or death. [1][9] Symptoms usually begin 10 to 15 days after being bitten by an infected Anopheles mosquito ...
Plasmodium vivax is a protozoal parasite and a human pathogen.This parasite is the most frequent and widely distributed cause of recurring malaria. [2] Although it is less virulent than Plasmodium falciparum, the deadliest of the five human malaria parasites, P. vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen).
Plasmodium rodhaini Brumpt, 1939. Plasmodium malariae is a parasitic protozoan that causes malaria in humans. It is one of several species of Plasmodium parasites that infect other organisms as pathogens, also including Plasmodium falciparum and Plasmodium vivax, responsible for most malarial infection.
Haemosporidium vigesimotertianae Lewkowicz, 1897. Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. [2] The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria.
West Nile virus. About 2 in 10 people infected with West Nile virus develop symptoms, which can include fever and swelling of the brain. About 1 in 10 people who develop severe symptoms die. There ...
The mainstay of malaria diagnosis has been the microscopic examination of blood, utilizing blood films. [1] Although blood is the sample most frequently used to make a diagnosis, both saliva and urine have been investigated as alternative, less invasive specimens. [2] More recently, modern techniques utilizing antigen tests or polymerase chain ...
Infectious disease experts break it down. What happened last year? In 2023, there were 2,406 cases of West Nile virus detected in the U.S. over 47 states, according to data from the Centers for ...
As cells die and toxic products of invasive organism replication accumulate, disease symptoms appear. Because this process involves specific proteins produced by the infectious organism as well as the host cell, even a very small change in a critical protein may render infection difficult or impossible.
