This study aims to evaluate the effectiveness of social group and social group/provider interventions in increasing the demand (use and/or request) for MRDT among community members with fever or malaria-like illness in Ebonyi state, Nigeria.MethodsA three-arm, parallel, stratified cluster randomized design will be used to evaluate the effect of two interventions compared to control: control involves the usual practice of provision of MRDT services by public primary healthcare providers and patent medicine vendors; social group intervention involves the sensitization/education of social groups about MRDT; social group/provi...

Purpose of review Malaria threatens the lives of over 200 million individuals with the disease each year. Plasmodium falciparum is the predominant cause of severe malaria which may be lethal and result in neurocognitive sequelae despite appropriate treatment. We review recent advances regarding the pathophysiology of severe malaria and treatment recommendations for severe disease in the United States. Recent findings Infected red blood cell (iRBC) sequestration in microvascular beds is a critical factor in the development of severe malaria syndromes. Interactions between iRBC variant adhesive peptides and the endothel...

(Abstracted from Lancet 2019;393:1428–1439.) In Africa, malaria in pregnancy presents a risk to 50 million women each year due to Plasmodium falciparum infection. Although women in endemic areas are typically asymptomatic when infected with malaria parasites, the infection is associated with maternal anemia and adverse birth outcomes including miscarriage, stillbirth, preterm birth, low birth weight, and infant mortality.

More than 1,500 deaths and 2,500 people sickened – that’s the recent account of the ebola outbreak in the Democratic Republic of Congo (DRC) raging in the country since last August, and recently declared a public health emergency of international concern. Experts say efforts to contain the virus are hindered by biological, public health, political, and cultural issues, but we looked around what digital health technologies could do to mitigate the spread and the devastation of the infectious disease. The Spaghetti-like virus… The lethal Ebola virus first appeared in 1976 around a river in Congo &nda...

CONCLUSION: This study has shown that malaria in pregnancy causes a significant decrease in the platelet count and prolongation in the prothrombin (PT) and the activated partial thromboplastin time (APTT). There is need for the malaria and haemostatic parameters to be assayed routinely on pregnant women particularly those presenting to antenatal clinic with febrile illness.

During pregnancy, Plasmodium falciparum-infected erythrocytes (IE) accumulate in the intervillous spaces of the placenta by binding to chondroitin sulfate A (CSA) and elicit inflammatory responses that are associated with poor pregnancy outcomes. Primigravidae lack immunity to IE that sequester in the placenta and thus are susceptible to placental malaria (PM). Women become resistant to PM over successive pregnancies as antibodies to placental IE are acquired. Here, we assayed plasma collected at delivery from Malian and Tanzanian women of different parities for total antibody levels against recombinant VAR2CSA antigens (F...

Infections that reach the placenta via maternal blood target the fetal-placental barrier and are associated with reduced birth weight, increased stillbirth, miscarriage and perinatal mortality. Malaria during pregnancy can lead to infection of the placental tissue with adverse effects on the unborn child even if the parasite is successfully cleared, indicating that placental sufficiency is significantly compromised. Human samples and animal models of placental malaria have been used to unravel mechanisms contributing to this insufficiency and have implicated molecular pathways related to inflammation, innate immunity and n...

This report summarizes confirmed malaria cases in persons with onset of illness in 2016 and summarizes trends in previous years. DESCRIPTION OF SYSTEM: Malaria cases diagnosed by blood film microscopy, polymerase chain reaction, or rapid diagnostic tests are reported to local and state health departments by health care providers or laboratory staff members. Case investigations are conducted by local and state health departments, and reports are transmitted to CDC through the National Malaria Surveillance System (NMSS), the National Notifiable Diseases Surveillance System (NNDSS), or direct CDC consultations. CDC refer...

Conclusions Toxoplasma gondii infection induces a strong innate and adaptive immune response. While the innate immunity is important for controlling the early stages of the infection (Yarovinsky, 2014), the adaptive immunity is critical for restricting the parasite replication during the later stages (Gazzinelli et al., 1992). Amongst the adaptive immune subsets, CD8 T cells are the primary effector cells while CD4 T cells play an essential helper role to maintain long-term immunity (Casciotti et al., 2002). Notwithstanding, a robust CD8 T cell immunity induced during acute phase of infection, does not result in the total...
