Malaria continues to be a major health problem in more than 100 endemic countries located primarily in tropical and sub-tropical regions around the world. Malaria transmission is a dynamic process and involves many interlinked factors, from uncontrollable natural environmental conditions to man-made disturbances to nature. Almost half of the population at risk of malaria lives in forest areas. Forests are hot beds of malaria transmission as they provide conditions such as vegetation cover, temperature, rainfall and humidity conditions that are conducive to distribution and survival of malaria vectors. Forests often lack infrastructure and harbor tribes with distinct genetic traits, socio-cultural beliefs and practices that greatly influence malaria transmission dynamics. Here we summarize the various topographical, entomological, parasitological, human ecological and socio-economic factors, which are crucial and shape malaria transmission in forested areas. An in-depth understanding and synthesis of the intricate relationship of these parameters in achieving better malaria control in various types of forest ecosystems is emphasized.

“…Biochemical and molecular analyses and crosses established that this species is a complex composed of at least three “species”: one from southern USA, Mexico and Guatemala, another from Central America, Belize and South America and the third from Grenada Island (Dantur et al 2010). However, Manguin et al (1995) argued that there is a single species with three widely distributed populations: one in the United States, Mexico, Guatemala, and Belize, another in Colombia, Ecuador, Peru, Chile and Argentina and, finally, a locality type present on Grenada Island.…”

Here we present a comprehensive review of the literature on the vectorial importance of the major Anopheles malaria vectors in Colombia. We provide basic information on the geographical distribution, altitudinal range, immature habitats, adult behaviour, feeding preferences and anthropophily, endophily and infectivity rates. We additionally review information on the life cycle, longevity and population fluctuation of Colombian Anopheles species. Emphasis was placed on the primary vectors that have been epidemiologically incriminated in malaria transmission: Anopheles darlingi, Anopheles albimanus and Anopheles nuneztovari. The role of a selection of local, regional or secondary vectors (e.g., Anopheles pseudopunctipennis and Anopheles neivai) is also discussed. We highlight the importance of combining biological, morphological and molecular data for the correct taxonomical determination of a given species, particularly for members of the species complexes. We likewise emphasise the importance of studying the bionomics of primary and secondary vectors along with an examination of the local conditions affecting the transmission of malaria. The presence and spread of the major vectors and the emergence of secondary species capable of transmitting human Plasmodia are of great interest. When selecting control measures, the anopheline diversity in the region must be considered. Variation in macroclimate conditions over a species’ geographical range must be well understood and targeted to plan effective control measures based on the population dynamics of the local Anopheles species.

Contribución de los autores:Liliana Quintero: asesoría de la revisión, corrección del manuscrito e ideas para la discusión Jhon Carlos Castaño: revisión de la literatura científica y redacción del manuscrito Magda Beatriz López y Harold Ramírez: participación en la fase de campo y en la elaboración del informe de estas actividades que sirvió de base para la redacción del manuscrito Introducción. La malaria o paludismo es la enfermedad parasitaria transmitida por mosquitos vectores más frecuente en las regiones tropicales. Debido a diversos factores, incluido el cambio climático, la enfermedad puede aparecer o reaparecer en diferentes lugares del mundo. Objetivo. Describir un brote autóctono de malaria urbana en la ciudad de Armenia, Colombia. Materiales y métodos. Después de la consulta en un hospital de segundo nivel del sur de Armenia de dos niños con síntomas de malaria, cuyo diagnóstico mediante gota gruesa confirmó la presencia de trofozoítos de Plasmodium vivax, se visitó el sector donde residían para la búsqueda activa de casos. Se describieron las condiciones ambientales y socioculturales del sector y se recolectaron e identificaron entomológicamente larvas, pupas y adultos de mosquitos. Igualmente, se implementaron medidas de control y se evaluó su efectividad.Resultados. La búsqueda activa en la comunidad permitió la identificación de 11 casos probables de malaria, de los cuales se confirmaron por microscopía tres casos de malaria por P. vivax en niños. El análisis entomológico de las larvas y pupas de mosquitos mostró la presencia de Anopheles spp., Anopheles punctimacula y Anopheles argyritarsis. Conclusiones. Se reportó el primer brote autóctono de malaria por P.vivax en Armenia, asociado con un asentamiento subnormal en una comunidad indígena y se constató cómo en los márgenes del río Quindío se presentan las condiciones eco-epidemiológicas que permiten el ciclo de reproducción del mosquito vector de la malaria. Materials and methods:After two children consulted a second level hospital located in the south of Armenia with malaria symptoms and their diagnosis was confirmed through the presence of Plasmodium vivax trophozoites detected by a positive thick blood smear, a visit was conducted to the residence of the children. An active search for cases was carried out, the environmental and sociocultural conditions were described and mosquito larvae and pupae were collected and identified. Control measures were implemented and their effectiveness was evaluated as well. Results:The active search in the community allowed the identification of 11 probable cases, three of which were P. vivax malaria cases in children confirmed by blood microscopy. The entomological analysis of mosquito larvae and pupae showed Anopheles spp., Anopheles punctimacula and Anopheles argyritarsis. Conclusion: This is the first report of an autochthonous malaria outbreak by P. vivax in the city of Armenia, associated with the subnormal settlement of an indigenous community. The banks of the Quindío river offer the eco-epidemiolog...
