On April 25th, World Malaria Day provides an opportunity to reflect not only on the global burden of cases, but also on how our understanding of the disease continues to evolve, and the challenges that remain to eliminate it.

In the Americas, recent studies have shown that malaria transmission is more complex than what routine surveillance alone can capture. One important finding is the presence of low-density and asymptomatic infections that often go undetected, yet continue to sustain transmission within communities. This situation is further intensified by human mobility, as people move between rural and urban areas, and even across borders. These patterns highlight the need for stronger surveillance systems and improved data sharing to better monitor and respond to malaria. 

At the same time, studies of malaria parasites across the region show that they are highly diverse and constantly changing. In other words, malaria does not behave the same way everywhere. Its transmission is shaped by local conditions, such as the environment, human movement, and the control measures in place. This means that strategies that work well in one setting may not be as effective in another.

These advances have been made possible by the increasing use of malaria molecular surveillance (MMS), which has become a key tool to better understand transmission, detect hidden infections, and track changes in parasite populations over time. 

In this context, the MMS Américas Network brings together researchers and institutions across the region who have been contributing to this body of evidence. Looking ahead, the network aims not only to advance malaria research but also to strengthen capacity across the region. This includes promoting training and knowledge exchange through workshops and collaboration between laboratories, helping build a shared base of expertise across countries. The network also seeks to improve sustainability by strengthening regional coordination to support access to resources, laboratory tools, and bioinformatics capacity. In parallel, it seeks to harmonize methods and data analysis so that information generated in different countries can be more easily compared and used. 

On this World Malaria Day 2026, the message is clear: advancing toward elimination in the Americas will depend on our ability to detect what remains unseen, understand how malaria behaves in different contexts, and work collaboratively across borders.

Through science, innovation, and regional collaboration, a malaria-free future becomes increasingly within reach.
