“…The epidemiological dynamics of the Mayaro virus observed in the human population is quite similar to that of other arboviruses in Colombia, like dengue between 2004-2013 [72,73] and to the colonization of mosquitoes of epidemiological importance such as Ae. aegypti, the main vector in the Americas for dengue, chikungunya and Zika [75] and Ae. albopictus, the main vector of these arboviruses in Asia and Europe [27,76].…”

Background Mayaro virus (Togaviridae) is an endemic arbovirus of the Americas with epidemiological similarities with the agents of other more prominent diseases such as dengue (Flaviviridae), Zika (Flaviviridae), and chikungunya (Togaviridae). It is naturally transmitted in a sylvatic/rural cycle by Haemagogus spp., but, potentially, it could be incorporated and transmitted in an urban cycle by Aedes aegypti, a vector widely disseminated in the Americas. Methods The Mayaro arbovirus dynamics was simulated mathematically in the colombian population in the eight biogeographical provinces, bearing in mind the vector’s population movement between provinces through passive transport via truck cargo. The parameters involved in the virus epidemiological dynamics, as well as the vital rates of Ae. aegypti in each of the biogeographical provinces were obtained from the literature. These data were included in a meta-population model in differential equations, represented by a model structured by age for the dynamic population of Ae. aegypti combined with an epidemiological SEI/SEIR-type model. In addition, the model was incorporated with a term of migration to represent the connectivity between the biogeographical provinces. Results The vital rates and the development cycle of Ae. aegypti varied between provinces, having greater biological potential between 23 °C and 28 °C in provinces of Imerí, biogeographical Chocó, and Magdalena, with respect to the North-Andean Moorland (9.33–21.38 °C). Magdalena and Maracaibo had the highest flow of land cargo. The results of the simulations indicate that Magdalena, Imerí, and biogeographical Chocó would be the most affected regarding the number of cases of people infected by Mayaro virus over time. Conclusions The temperature in each of the provinces influences the local population dynamics of Ae. aegypti and passive migration via transport of land cargo plays an important role on how the Mayaro virus would be disseminated in the human population. Once this arbovirus begins an urban cycle, the most-affected departments would be Antioquia, Santander, Norte de Santander, Cesar (Provinces of Magdalena), and Valle del Cauca, and Chocó (biogeographical province of Chocó), which is why vector control programmes must aim their efforts at these departments and include some type of vector control to the transport of land cargo to avoid a future Mayaro epidemic.

Introducción. Aedes albopictus es vector de arbovirus, como Flavivirus, Alphavirus, Bunyavirus, Phlebovirus, Orbivirus y Picornavirus. Muchos son agentes etiológicos de enfermedades en humanos. Actualmente, A. albopictus se encuentra en expansión geográfica por su adaptación a diversos ambientes y tipos de criaderos. En Colombia, este mosquito fue reportado por primera vez en 1998 y, hasta el momento, se ha registrado en 10 departamentos.Objetivo. Determinar la presencia de A. albopictus en Yopal, Casanare. Materiales y métodos. En una búsqueda activa de larvas de A. aegypti en la zona industrial de Yopal, se observaron por primera vez mosquitos adultos de A. albopictus. Por lo anterior, se realizó la inspección en el intradomicilio y el peridomicilio de las viviendas en ocho localidades del municipio, en la cual se recolectaron larvas y pupas al inspeccionar hábitats larvarios, y hembras adultas, mediante capturas sobre atrayente humano protegido. Resultados. Se identificaron 755 larvas de mosquitos, 71,5 % de A. aegypti, 24,8 % de A. albopictus, 3,2 % de Culex quinquefasciatus y 0,8 % de C. coronator y C. nigripalpus. Se capturaron 37 mosquitos adultos de A. albopictus. Los depósitos con mayor abundancia de este vector fueron las llantas.Conclusión. Ante la presencia de A. albopictus se sugiere intensificar el sistema de vigilancia entomológica para detectar nuevas poblaciones dentro del departamento y en las áreas cercanas. Se debe poner atención a los criaderos artificiales de las zonas cercanas a los parqueaderos de vehículos de transporte de alimentos, insumos y maquinaria, procedentes de áreas con presencia del vector.

Contribución de los autores:Andrés Gómez-Palacio: concepción y análisis del estudio, escritura del manuscrito Juan Suaza-Vasco: recolección de ejemplares y desarrollo del trabajo en campo Sandra Uribe: participación en todas las etapas de la investigación Todos los autores participaron en la clasificación taxonómica y los análisis genéticos y moleculares. Mosquitoes were processed for dengue virus identification, and a fragment of the NS3 gen was sequenced and compared with DENV-2 genotypes reported in the literature. Infección deResults: Sequence analysis of COI indicated Ae. albopictus individuals were similar to those recently reported in Colombia, and genetically close to those from other regions worldwide. Among the pools tested one was positive for DENV-2, and the NS3 analysis indicated it belonged to the Asian-American clade.
