Special Issue Information

Dear Colleagues,

Malaria continues to have a devastating global health burden, being responsible for 263 million cases and 597,000 deaths in 2023, across 83 countries. This is likely to continue for the foreseeable future unless further preventative strategies are implemented. Progress is being made: the forwarding by the World Health Organisation (WHO) in October 2021 of the first vaccine against Plasmodium falciparum malaria as well as developments in monoclonal antibodies for malaria prevention show this. However, therapeutic strategies are being threatened by the emergence of partial artemisinin resistance in certain parts of the world including South America, East Africa, and Southeast Asia.

The aim of this Special Issue is to explore and further expand our understanding of the evolving epidemiology and immunopathogenesis of malaria (all species), as well as to report on novel developments in its prevention, diagnosis, and treatment. A range of studies, including case reports and series, cohort and case–control studies, narrative reviews, and systematic reviews and meta-analyses, are welcome.

Malaria is one of the most severe parasitic diseases worldwide and presents unique challenges in solid organ transplantation (SOT). Donor-derived malaria, although rare, can cause severe morbidity and mortality due to diagnostic delays and the altered immunity of transplant recipients. This manuscript synthesizes available evidence on transmission routes, diagnostic timing, clinical manifestations, geographic variability, and cyclosporin’s mechanistic antimalarial properties, and integrates recommendations from major transplant associations. The findings highlight that global travel and migration have increased donor-derived malaria risk, Polymerase Chain Reaction (PCR) is the most sensitive screening tool, and cyclosporin shows potent in vitro antiplasmodial activity without documented clinical protection. International guidelines consistently emphasize epidemiologic donor screening, risk-based laboratory testing, post-transplant surveillance, and pre-travel prophylaxis. Full article

Performance of High-Resolution Melting Analysis for Molecular Detection and Species Differentiation of Malaria: A Scoping Review

Malaria diagnosis remains challenging in low-density, asymptomatic, mixed-species, and non-falciparum infections. This scoping review mapped the diagnostic and operational evidence for high-resolution melting (HRM) analysis in malaria. Following PRISMA-ScR guidance, PubMed and Scopus were searched for English-language studies published between 2016 and 2026. Two reviewers independently screened records in Rayyan. Of 162 records identified, 15 studies met the eligibility criteria. Most assays targeted 18S rRNA, although mitochondrial, apicoplast, species-specific, and resistance-associated markers were also evaluated. Reported sensitivity ranged from 91.76% to 100%, and specificity generally exceeded 92%. HRM enabled differentiation of major human-infecting Plasmodium species and detected mixed, low-parasitemia, and submicroscopic infections that were missed by microscopy or rapid diagnostic tests. However, substantial heterogeneity in assay targets, platforms, comparators, and reporting limited direct comparison. Current applications remain laboratory-developed and require HRM-capable real-time PCR instruments, dedicated analytical software, and trained personnel. HRM is therefore a promising complementary method for reference laboratories and malaria surveillance, but standardized assays, multicentre validation, and implementation studies are required before routine or decentralized use.

Plasmodium falciparum with deletions in the pfhrp2 and pfhrp3 genes has increasingly challenged national malaria control efforts worldwide by reducing the reliability of HRP2-based rapid diagnostic tests. This review explores available reports and evidence on this issue across Latin America. The results show a varied distribution, with countries such as Peru, Colombia, and Brazil reporting the emergence and spread of multidrug-resistant strains. Meanwhile, Caribbean countries and parts of Central America report low prevalence or no deletions. Understanding these patterns is essential for adjusting surveillance strategies, especially in countries nearing malaria elimination. Full article

Malaria continues to impose a devastating disease burden globally despite control efforts spanning decades. Its elimination has been hindered by parasite and vector complexity and emerging drug and insecticide resistance, along with unremitting barriers to uptake of preventative strategies largely driven by social inequities, cost constraints, and logistical challenges in implementation. This review synthesises current and emerging prevention strategies, including vector control, chemoprevention and immunoprophylaxis. Insecticide-treated nets and indoor residual spraying remain cornerstones of vector control, although their effectiveness is increasingly compromised by widespread insecticide resistance. Chemoprevention, including intermittent preventive treatment in pregnancy and seasonal malaria chemoprevention in children, has proven highly efficacious, yet uptake remains below WHO targets and concerns about drug resistance remain. Recent advances in vaccines, notably RTS,S/AS01 and R21/Matrix-M, represent landmark achievements, with large-scale rollouts demonstrating reductions in severe disease and mortality. Novel approaches, such as monoclonal antibodies and genetically modified mosquitoes, offer promising avenues for future prevention. However, challenges remain in ensuring equitable access, sustaining efficacy in the face of evolving parasite and vector biology, and integrating interventions into diverse health systems. This review highlights the need for adaptive, multifaceted approaches to achieve malaria elimination goals. Full article

Transmission of malaria by blood transfusion is rare in non-endemic countries but can lead to serious complications in blood recipients. Increasing travel to and immigration from regions at risk for tropical diseases poses a challenge to blood donation services, which are striving to reduce the number of blood donor deferrals while ensuring a high level of blood safety. National guidelines of the Blood Transfusion Service of the Swiss Red Cross demand that donors at risk are serologically tested for malaria antibodies. Here, we summarize the numbers of malaria tests performed and the results obtained since the introduction of mandatory testing in Switzerland in 2007. From malaria-positive donors, information on travels to endemic areas and place of origin, or if malaria symptoms were experienced and if prophylaxis was taken, was requested in a post-donation questionnaire.
