This study recorded malaria signs and the rate of parasitaemia among asymptomatic schoolchildren in Hajr valley, Hadhramout governorate, Yemen. Tests were made for malaria parasites and anaemia in 469 randomly selected primary-school children aged 6-11 years, together with clinical examination to determine spleen size, and interviews to study sociodemographic factors. Of the children, 12.8% had...
UNLABELLED Malaria surveillance and interventions in endemic countries often target young children at highest risk of malaria morbidity and mortality. We aimed to determine whether school-age children and adults not captured in surveillance serve as a reservoir for malaria infection and may contribute to malaria transmission. Cross-sectional surveys were conducted in one rainy and one dry seaso...
Background: Malaria impacts >24 million children globally, resulting in >300,000 child deaths annually low- and middle-income countries (LMICs). Little is known about the association between malarial infection its impact on cognition behavior. Our objective was to determine different types of malaria with cognitive behavioral outcomes among living LMICs.Methods: We systematically searched...
INTRODUCTION: Paraguay was among the 16 countries that reported zero indigenous malaria cases in 2014. METHODS: A cross-sectional observational descriptive study was performed in 100 adults from Santa Teresa, Paraguay. Parasite detection was carried out using seminested multiplex polymerase chain reaction (PCR) and microscopy. RESULTS Among the participants, 44% were female and 56% were mal...
BACKGROUND Malaria parasitemia among pregnant women is associated with complications to mother and the unborn fetus. There is paucity of data on asymptomatic malaria parasitemia, particularly in the northwest region of Nigeria. The objectives of this study were to determine the prevalence of malaria parasitemia in asymptomatic pregnant women and to estimate the packed cell volume (PCV) of this ...
BACKGROUND In Sub-Saharan African countries, including Ethiopia, malaria in pregnancy is a major public health threat which results in significant morbidities and mortalities among pregnant women and their fetuses. In malaria endemic areas, Plasmodium infections tend to remain asymptomatic yet causing significant problems like maternal anemia, low birth weight, premature births, and still birth...
Identifying molecular predictors and mechanisms of malaria disease is important for understanding how Plasmodium falciparum malaria is controlled. Transcriptomic studies in humans have so far been limited to retrospective analysis of blood samples from clinical cases. In this prospective, proof-of-principle study, we compared whole-blood RNA-seq profiles at pre-and post-infection time points fr...
The aim of this study was to examine the impact of haemoglobin variants HbAS and HbAC on asymptomatic malaria compared to normal HbAA among adults living in a malaria hyperendemic area. Seemingly healthy individuals, 2,237 (≥16 years) without clinical symptoms in Iwo, Southwestern Nigeria were screened for this study after informed consent was obtained. A sample of 5 mL of blood was withdrawn f...
BACKGROUND Asymptomatic low-density gametocyte carriers represent the majority of malaria-infected individuals. However, the impact of recommended treatment with single low dose of primaquine and an artemisinin-based combination therapy to reduce transmission in this group is unknown. METHODS This was a four-arm, open label, randomized controlled trial comparing the effect of dihydroartemisin...
