Hotspots of Malaria Transmission in the Peruvian Amazon: Rapid Assessment through a Parasitological and Serological Survey

Abstract: BackgroundWith low and markedly seasonal malaria transmission, increasingly sensitive tools for better stratifying the risk of infection and targeting control interventions are needed. A cross-sectional survey to characterize the current malaria transmission patterns, identify hotspots, and detect recent changes using parasitological and serological measures was conducted in three sites of the Peruvian Amazon.Material and MethodsAfter full census of the study population, 651 participants were interviewed, clin… Show more

“…Since then, the number of malaria cases again began to rise (Figures 2 and 3), with the total number of reported P. vivax and P. falciparum cases increasing from 20,421 to 49,745 and from 2,639 to 12,475 cases, respectively, from 2011 to 2015 3. One leading hypothesis to explain the rapid resurgence of malaria after 2011 is that the Peruvian NMCP was politically and financially limited so that it could not keep up with the intense control interventions in the Amazon after the PAMAFRO project ended 6,42. Because of such a rapid resurgence, other factors must have contributed including weather changes (i.e., increased rain, increased river height related to Andean snow melt related to climate change, as well as social and political disorder in Iquitos in recent years.…”

“…More than 80% of the total malaria clinical cases detected by PCD in Loreto are concentrated among only 10–20% of the total communities of the department 6. Moreover, cross-sectional studies using LM for malaria diagnosis have also showed that malaria parasite prevalence varied considerably across communities around Iquitos (capital of Loreto),16,47 and those differences remained or even increased when using more sensitive diagnostic tests 16,48.…”
