Genomic epidemiology of Plasmodium knowlesi reveals putative genetic drivers of adaptation in Malaysia.

Sabah, Malaysia, has amongst the highest burden of human Plasmodium knowlesi infection in the world, associated with increasing encroachment on the parasite's macaque host habitat. However, the genomic make-up of P. knowlesi in Sabah was previously poorly understood.

The 1985 Plasmodium vivax malaria elimination campaign in Santa Catarina, Brazil: the feasibility of using serology amid other integrated tools in the last mile.

This report outlines the process of malaria elimination in two municipalities, São Francisco do Sul and Araquari, located in Santa Catarina, Southern Brazil, from 1980 to 1985. Before 1948, Santa Catarina reported an annual average of nearly 60,000 malaria cases. The primary vector responsible for transmission was Anopheles (Kerteszia) cruzii, which exhibited high infestation levels in endemic areas.

Spatial distribution of Plasmodium vivax Duffy Binding Protein copy number variation and Duffy genotype, and their association with parasitemia in Ethiopia.

Background: Duffy Binding Protein (PvDBP) binding to the Duffy antigen receptor for chemokine (DARC) is essential for Plasmodium vivax invasion of human reticulocytes. PvDBP copy number variation (CNV) might increase parasite invasion and thus parasitemia. We examined the spatial distribution of PvDBP CNVs and DARC genotypes and their association with parasitemia in P.

Incorporating Community Case Management in Risk-Based Surveillance for Malaria Elimination in the Dominican Republic.

As countries strive for malaria elimination, it is crucial to gather sufficient evidence to confirm the absence of transmission. Routine surveillance data often lack the sensitivity to detect community transmission at low levels. In the Dominican Republic, community health workers (CHWs) have been deployed in malaria foci to perform active case detection.

Quantifying Plasmodium vivax radical cure efficacy: a modelling study integrating clinical trial data and transmission dynamics.

Background: Plasmodium vivax forms dormant liver stages (hypnozoites) that can reactivate weeks to months after primary infection. Radical cure requires a combination of antimalarial drugs to kill both the blood-stage and liver-stage parasites. Hypnozoiticidal efficacy of the liver-stage drugs primaquine and tafenoquine cannot be estimated directly because hypnozoites are undetectable.
