The Global Technical Strategy for Malaria 2016-2030 targets eliminating malaria from at least 35 countries and reducing case incidence by 90% globally. The importation of parasites due to human mobilization poses a significant obstacle to achieve malaria elimination as it can undermine the effectiveness of local interventions. Gaining a comprehensive understanding of parasite importation is essential to support control efforts and advance progress toward elimination. Parasite genetic data is widely used to investigate the spatial and temporal dynamics of imported infections. In this context, this systematic review aimed to aggregate evidence on the application of parasite genetic data for mapping imported malaria and the analytical methods used to analyze it. We discuss the advantages and limitations of the genetic approaches employed and propose a suitable type of genetic data along with an analytical framework to discriminate imported malaria infections from local infections. The findings offer potential actionable insights for national control programs, enabling them select the most effective methods for detecting imported cases. This also may aid in the evaluation and refinement of elimination programs by identifying high-risk areas and enabling the targeted allocation of resources to these regions.

Article Synopsis
- Mansonella perstans is a filarial parasite endemic to sub-Saharan Africa with inconsistent treatment protocols and unclear effectiveness, prompting a study to analyze the presence of Wolbachia in its samples.
- The study analyzed 19 samples from patients infected with M. perstans from various West African countries, finding that 74% contained Wolbachia, with some countries having Wolbachia detected for the first time.
- Results indicated that the presence of Wolbachia could influence treatment strategies, specifically suggesting that doxycycline could be effective, although discrepancies in sample results may point to technical challenges or the existence of different M. perstans populations.

In Japan, malaria is rare, and only a few institutions have the diagnostic capabilities to treat it. In falciparum malaria, the symptoms and signs of the disease are non-specific, and diagnostic delay in symptomatic patients can be fatal. Herein, we describe a case of falciparum malaria that achieved good outcomes in a patient who initially visited an institution in Japan that lacked malaria diagnostic resources.

The continued emergence of antimalarial drug resistance highlights the need to develop new antimalarial therapies. Unfortunately, new drug development is often hampered by undesirable drug-like properties of lead compounds. Prodrug approaches temporarily mask undesirable compound features, improving bioavailability and target penetration.
