This study will look at blood samples taken from 300 preterm babies and newborns admitted for inpatient care at Hopital Gabriel Toure in Bamako, Mali, and to gather information that will help the investigators verify the role of malaria in illness of very small babies. Blood samples will be taken from the mothers so that the investigators can find out if they have a malaria infection and how their body fights malaria. The investigators will also determine whether the mother and newborn baby are infected with the same malaria parasite. The information from this study may be used to improve malaria treatment in very small babies. Mothers and babies whose blood is tested will receive treatment for malaria as recommended by the National Malaria Control Program (NCMP).
The purpose of this cross-sectional study is to determine the rate of congenital and acquired malaria in inpatient neonates at a tertiary pediatric hospital in Bamako, Mali. The primary study endpoint will be the number of infants with malaria infection as detected by the positivity of one of the three malaria diagnosis assays. The secondary study endpoints will be: (1) the rate of congenital malaria, (2) the rate of acquired malaria, (3) the prevalence of antimalarial antibodies in neonates, and (4) the prevalence of specific hemoglobin types in the study population. Neonates of both sexes who weigh at least 2000g, are 0 - 28 days old, and are referred to the Unit of Reanimation and Neonatology of Hopital Gabriel Toure in Bamako, Mali, for inpatient care are eligible for enrollment in this two-year study. After informed parental consent is obtained, approximately 2 ml of venous blood will be collected for malaria diagnosis by OptiMal test, microscopy and polymerase chain reaction (PCR). If in the clinician's judgment drawing blood is not feasible, a small blood sample will be obtained by heel prick from the infants and tested for the presence of malaria parasites. If any of the three infant malaria tests is positive, parenteral quinine will be administered as per the National Malaria Control Program (NMCP) treatment guidelines. If malaria is detected in mothers, standard malaria therapy will be administered according to the National Malaria Control Program (NMCP) treatment guidelines. Blood will be obtained from mothers for molecular diagnosis of malaria infection and characterization of the genetic profile of mother's malaria infections.

The purpose of this pilot study is to evaluate the use of (1) 'malaria prevalence', (2) 'malaria incidence' and (3) 'malaria mortality' as a measure of malaria transmission in The Gambia, ...
We wish to understand how resistance to malaria develops and how this affects the growth rate of malaria in individuals who have past exposure to malaria.
Purpose of the study is to determine whether LSA-1/AS02A combination malaria vaccine is effective at preventing malaria.
The goal of this study is to develop a safe, well tolerated, and highly efficacious azithromycin combination treatment for uncomplicated falciparum malaria. Azithromycin is a drug that has...
The purpose of the study is to determine whether LSA-1/AS01B combination malaria vaccine is effective at preventing malaria.
Sick neonates in malaria endemic areas are frequently transfused with donor blood unscreened for malaria parasite. Consequently, they are at risk of transfusional malaria which can lead to increased n...
Rapid and precise diagnosis of malaria is an essential element in effective case management and control of malaria. Malaria microscopy is used as the gold standard for malaria diagnosis, however resul...
Insecticide-treated nets (ITNs) reduce malaria morbidity and mortality in endemic areas. Despite increasing availability, the use of ITNs remains limited in some settings. Poor malaria knowledge is a ...
Although consensus exists that malaria in pregnancy (MiP) increases the risk of malaria in infancy, and eventually nonmalarial fevers (NMFs), there is a lack of conclusive evidence of benefits of MiP ...
Although the malaria burden in the Lao PDR has gradually decreased, the elimination of malaria by 2030 presents many challenges. Microscopy and malaria rapid diagnostic tests (RDTs) are used to diagno...
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.
Vaccines made from antigens arising from any of the four strains of Plasmodium which cause malaria in humans, or from P. berghei which causes malaria in rodents.
A protozoan parasite that causes vivax malaria (MALARIA, VIVAX). This species is found almost everywhere malaria is endemic and is the only one that has a range extending into the temperate regions.
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 protozoan parasite that occurs naturally in the macaque. It is similar to PLASMODIUM VIVAX and produces a type of malaria similar to vivax malaria (MALARIA, VIVAX). This species has been found to give rise to both natural and experimental human infections.
Malaria is a serious tropical disease spread by mosquitoes. If malaria is not diagnosed and treated promptly, it can be fatal. What causes malaria? Malaria is caused by a type of parasite known as Plasmodium. There are many different types of Plasmod...
