    • Anopheles albimanus (Diptera: Culicidae) Ensemble Distribution Modeling: Applications for Malaria Elimination 

      Rhodes, Charlotte G.; Loaiza, Jose R.; Romero, Luis Mario; Gutiérrez Alvarado, José Manuel; Delgado, Gabriela; Rojas Salas, Obdulio; Ramírez Rojas, Melissa; Aguilar Avendaño, Carlos; Maynes, Ezequías; Valerín Cordero, José A.; Soto Mora, Alonso; Rigg, Chystrie A.; Zardkoohi, Aryana; Prado, Monica; Friberg, Mariel D.; Bergmann, Luke R.; Marín Rodríguez, Rodrigo; Hamer, Gabriel L.; Fernando Chaves, Luis (MDPI, 2022)
      In the absence of entomological information, tools for predicting Anopheles spp. presence can help evaluate the entomological risk of malaria transmission. Here, we illustrate how species distribution models (SDM) could ...
    • Characterization of a recent malaria outbreak in the autonomous indigenous region of Guna Yala, Panama 

      Calzada, José E; Marquez, Ricardo; Rigg, Chystrie; De La Cruz, Manuel; Chaves, Luis F; Cáceres, Lorenzo (BioMed Central, 2015-11-17)
      Background: This study aims to describe the epidemiological and entomological factors associated with a recent malaria outbreak that occurred in 2012 in a socially marginalized population from Guna Yala Comarca in Panama. ...
    • Climatic fuctuations and malaria transmission dynamics, prior to elimination, in Guna Yala, República de Panamá 

      Amarilis Hurtado, Lisbeth; Calzada, José E.; Rigg, Chystrie A.; Castillo, Milagros; Chaves, Luis Fernando (BioMed Central, 2018-02-20)
      Background: Malaria has historically been entrenched in indigenous populations of the República de Panamá. This scenario occurs despite the fact that successful methods for malaria elimination were developed during the ...
    • Indian Ocean Dipole and Rainfall Drive a Moran Effect in East Africa Malaria Transmission 

      Chaves, Luis Fernando; Satake, Akiko; Hashizume, Masahiro; Minakawa, Noboru (Oxford University Press, 2012-06-15)
      Background. Patterns of concerted fluctuation in populations—synchrony—can reveal impacts of climatic variability on disease dynamics. We examined whether malaria transmission has been synchronous in an area with a common ...
    • Indian Ocean Dipole drives malaria resurgence in East African highlands 

      Hashizume, Masahiro; Chaves, Luis Fernando; Minakawa, Noboru (SCIENTIFIC REPORTS, 2012-02-16)
      Malaria resurgence in African highlands in the 1990s has raised questions about the underlying drivers of the increase in disease incidence including the role of El-Nin ̃o-Southern Oscillation (ENSO). However, climatic ...
    • Malaria elimination in Costa Rica: changes in treatment and mass drug administration 

      Chaves, Luis Fernando; Romero-Vega, L. Mario; Huber, John H.; Rojas Salas, Obdulio; Ramírez Rojas, Melissa; Gutiérrez Alvarado, José M.; Alex Perkins, T.; Prado, Monica; Marín Rodríguez, Rodrigo (MDPI AG, 2020-06-30)
      Costa Rica is a candidate to eliminate malaria by 2020. The remaining malaria transmission hotspots are located within the Huétar Norte Region (HNR), where 90% of the country’s 147 malaria cases have occurred since 2016, ...
    • Presence and potential distribution of malaria‑infected New World primates of Costa Rica 

      Dolz, Gaby; Chaves, Andrea; Ibarra-Cerdeña, Carlos N.; Núñez, Genuar; Ortiz-Malavasi, Edgar; BERNAL VALLE, SOFÍA; Gutierrez-Espeleta, Gustavo A. (Malaria Journal, 2022-01-08)
      Background: In South and Central America, Plasmodium malariae/Plasmodium brasilianum, Plasmodium vivax, Plasmodium simium, and Plasmodium falciparum has been reported in New World primates (NWP). Specifically in Costa Rica, ...
    • Re-emergence of Plasmodium malariae in Costa Rica 

      Dolz, Gaby; Calvo, Nidia; Morera, Jessica; Solórzano-Morales, Antony; Herrero-Acosta, Marco Vinicio (Universidad Nacional, Costa Rica, 2015-04-30)
      In this paper we report the diagnosis of four cases of Plasmodium malariae in humans in Costa Rica, using parasitological and molecular techniques. Real-time PCR detected P. malariae in all four samples and established ...
    • Regime shifts and heterogeneous trends in malaria time series from Western Kenya Highlands 

      Chaves, Luis Fernando; Hashizume, Masahiro; Satake, Akiko; Minakawa, Noboru (Parasitology, 2011-10)
      Large malaria epidemics in the East African highlands during the mid and late 1990s kindled a stream of research on the role that global warming might have on malaria transmission. Most of the inferences using temporal ...
    • The Impact of Deforestation, Urbanization, and Changing Land Use Patterns on the Ecology of Mosquito and Tick-Borne Diseases in Central America 

      Ortiz, Diana I.; Romero Vega, Luis M.; Wagman, Joseph; Troyo, Adriana; Piche-Ovares, María Marta (MDPI, 2021)
      Central America is a unique geographical region that connects North and South America, enclosed by the Caribbean Sea to the East, and the Pacific Ocean to the West. This region, encom- passing Belize, Costa Rica, ...
