Submicroscopic infections and two malaria vectors are major contributors to residual malaria in an Amazonian village in Peru.

ABSTRACT: In the Loreto region of Amazonian Peru, the primary malaria vector is Nyssorhynchus (or Anopheles) darlingi. The present year-long study sought to identify specific landscapes with the greatest risk of Plasmodium transmission, incorporating epidemiological data, landscape stratification models, satellite imagery, and vector biology. A monthly longitudinal cohort study and population screening of all residents of the focal village Santa Rita detected, among 353 inhabitants enrolled, a ratio of 17:1 submicroscopic/ microscopic malaria infections. Microscopy-detected human infections were seasonal, generally peaking with rising river levels and increasing rainfall, but submicroscopic infections, detected by qPCR, were perennial. Despite high mosquito net usage, inhabitants with outdoor occupa
