Description
Jacob van der Ende and co-authors hunt for silent malaria infections in Ecuador's Amazonian Putumayo region, in a 2025 study. Ecuador nears malaria elimination, but this border area sits next to high-transmission zones in Colombia and Peru. People can carry the parasite with no symptoms, seeding new cases while routine checks miss them.
The team tested 293 healthy people in four river communities during the 2023 rainy season. Rapid tests found no infections at all. Microscope checks found three, and sensitive gene tests found five, all at very low levels. The study warns that elimination plans need molecular surveillance to catch this hidden reservoir. The infections clustered in the mid-to-late rainy season, mostly in males.
