Malaria continues to be a major threat to public health in tropical regions, primarily affecting sub-Saharan Africa but also Asia, the Middle East, and Latin America. Malaria cases in Honduras have seen a significant decline and the country aims to eliminate the disease by 2030. This study examines the genetic diversity of and in Honduras using four molecular markers (, , , and ), and the chloroquine resistance marker in the context of the elimination phase.

Background: Amazonas is a region in northern Peru with the second-highest incidence of malaria. Approximately 95% of the cases are reported in the Condorcanqui province, where native communities living along the banks of Santiago River lack access to potable water, sewage, and electricity. This study aimed to analyse malaria's spatial, temporal, and climatic characteristics in Condorcanqui to guide future studies and prevention strategies.

In Colombia, human leishmaniasis is endemic in rural areas, with increasing reports of outbreaks and cases in urban areas. Cartagena, an urban city in the Colombian Caribbean with a wildland-urban interface, faced its first local cases between 2011 and 2015. Despite reports, visceral leishmaniasis (VL) remains neglected and understudied and almost devoid of active surveillance.

Background: Federal guidelines and equitable care mandate that patients who use a language other than English receive interpretation in their preferred language. Substantial variability exists in interpreter use in intensive care settings. We aimed to increase the rate of interpretations in our pediatric intensive care unit (PICU) through a series of targeted interventions.

Article Synopsis
  • Plasmodium vivax is increasingly problematic in tropical regions, particularly where Plasmodium falciparum is declining, due to its ability to cause relapse infections that hinder treatment efforts.
  • Researchers developed four specialized molecular inversion probe (MIP) genotyping panels targeting key genetic variations in P. vivax, aiming to better understand its population structure and resistance mechanisms.
  • Analysis using these panels on 866 infections in the Peruvian Amazon revealed significant findings, including transmission networks, gene mutations related to drug resistance, and potential vaccine targets, suggesting these tools can enhance research and control of P. vivax globally.
