To report a case of bilateral malarial retinopathy secondary to uncomplicated Plasmodium vivax malaria. A 45-year-old male patient presented with sudden onset of diminution of vision both eyes and was treated for P. vivax malaria 1 week before the ocular symptoms. Dilated fundus examination revealed multiple intraretinal (dot-blot, flame shaped) hemorrhages, cotton-wool spots, and areas of retinal whitening predominantly involving the posterior pole both eyes, with features being more severe in left eye. Optical coherence tomography revealed bilateral subfoveal neurosensory detachments. Retinopathy is typically rare in the settings of P. vivax malaria, albeit commonly seen in patients with cerebral malaria (Plasmodium falciparum).

Background: In Myanmar, progress towards malaria elimination has stagnated in some areas requiring deployment of new tools and approaches to accelerate malaria elimination. While there is evidence that networks of community-based malaria workers and insecticide-treated nets (ITNs) can reduce malaria transmission in a variety of settings, evidence for the effectiveness of other interventions, such as topical repellents, is limited. Since malaria transmission in Myanmar occurs outdoors, mainly among forest-goers, this study tested the effectiveness of topical repellents in combination with supplemental ITN distribution and strengthened networks of malaria workers.

Transmission-blocking vaccines (TBVs) targeting sexual-stage antigens represent a critical tool for malaria control and elimination through inhibiting parasite development within mosquitoes. P230, displayed on the surface of gametocytes and gametes, plays a crucial role in gamete fertilization and is one of the leading TBV candidates for both Plasmodium falciparum and P. vivax.

Background: Daily primaquine-induced hemolysis is a common cause of complications during Plasmodium vivax malaria treatment in individuals with glucose 6-phosphate dehydrogenase deficiency (G6PDd). Alternative regimens balancing safety and efficacy are needed.
Methods: G6PDd participants with P.

Background: India is committed to malaria elimination by the year 2030. According to the classification of malaria endemicity, the National Capital Territory of Delhi falls under category 1, with an annual parasite incidence of <1, and was targeted for elimination by 2022. Among others, population movement across states is one of the key challenges for malaria control, as it can result in imported malaria, thus introducing local transmission in an area nearing elimination.

Background: The Highlands of Papua New Guinea are non-endemic for malaria compared to the rest of the country. This study aimed to explore the local transmission of malaria in the Highlands through a cross-sectional school survey coupled with reactive case detection.
Methods: Between July and November 2019, 5575 schoolchildren and 1048 household members were screened for malaria using Rapid Diagnostic Tests, subsequently validated by light microscopy.
