Pilot Study to Estimate the Burden and Distribution of Plasmodium Falciparum Malaria in Kalifabougou, Mali in Preparation for a Prospective Cohort Study of Naturally-Acquired Malaria Immunity

2014-08-27 03:12:17 | BioPortfolio

Summary

Plasmodium falciparum malaria remains a global public health threat. Leading malaria vaccine candidates confer only partial short-lived protection at best. An understanding of the mechanisms by which humans acquire malaria immunity through repeated P. falciparum infections may aid the development of a malaria vaccine. This pilor study is designed to initiate the epidemiological groundwork for a future prospective cohort study of acquired malaria immunity in Kalifabougou, Mali, a rural village of approximately 5 000 individuals who are exposed to seasonal P. falciparum transmission each year from July through December. This study will estimate the age-stratified point prevalence of P. falciparum infection before the malaria season and at the peak of the 6-month malaria season, and it will estimate the age-stratified incidence of symptomatic p. falciparum infection during the 6-month malaria season. The spatial distribution of asymptomatic P. falciparum infections and incident malaria cases within the village of Kalifabougou will be determined by merging the prevalence and incidence data with census and Global Positioning System (GPS) data.

Medical and Biotech [MESH] Definitions

A species of protozoa that is the causal agent of falciparum malaria (MALARIA, FALCIPARUM). It is most prevalent in the tropics and subtropics.

Malaria caused by PLASMODIUM FALCIPARUM. This is the severest form of malaria and is associated with the highest levels of parasites in the blood. This disease is characterized by irregularly recurring febrile paroxysms that in extreme cases occur with acute cerebral, renal, or gastrointestinal manifestations.

A synthetic TETRACYCLINE derivative with similar antimicrobial activity. Animal studies suggest that it may cause less tooth staining than other tetracyclines. It is used in some areas for the treatment of chloroquine-resistant falciparum malaria (MALARIA, FALCIPARUM).

Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day.

A protozoan disease caused in humans by four species of the PLASMODIUM genus: PLASMODIUM FALCIPARUM; PLASMODIUM VIVAX; PLASMODIUM OVALE; and PLASMODIUM MALARIAE; and transmitted by the bite of an infected female mosquito of the genus ANOPHELES. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high FEVER; SWEATING; shaking CHILLS; and ANEMIA. Malaria in ANIMALS is caused by other species of plasmodia.
