Assessing present and future suitability of European cities to the Asian Tiger ...
Oliveira, Sandra; Rocha, Jorge; Sousa, CA; Capinha, CésarThe Asian Tiger mosquito (Aedes albopictus) is already established in many countries of Europe and cities are particularly vulnerable to the spread of vector-borne diseases. We evaluated the suitability of 62 large urban areas in Europe to the establishment of this mosquito, based on the level of agreement between published predictions of its potential distribution. We classified levels of suitability and uncer...
Dengue importation into Europe
Salami, Donald; Capinha, C.; Martins, MR; Sousa, CAThe spread of dengue through global human mobility is a major public health concern. A key challenge is understanding the transmission pathways and mediating factors that characterized the patterns of dengue importation into non-endemic areas. Utilizing a network connectivity-based approach, we analyze the importation patterns of dengue fever into European countries. Seven connectivity indices were developed to...
Phylogeography and invasion history of Aedes aegypti, the Dengue and Zika mosqu...
Salgueiro, P; Serrano, Célia; Gomes, Bruno; Alves, Joana; Sousa, CA; Abecasis, AB; Pinto, JAedes-borne arboviruses have spread globally with outbreaks of vast impact on human populations and health systems. The West African archipelago of Cape Verde had its first outbreak of Dengue in 2009, at the time the largest recorded in Africa, and was one of the few African countries affected by the Zika virus epidemic. Aedes aegypti was the mosquito vector involved in both outbreaks. We performed a phylogeogr...
Origin and expansion of the mosquito Aedes aegypti in Madeira Island (Portugal)
Rocha Seixas, Gonçalo Filipe; Salgueiro, P; Bronzato-Badial, A.; Gonçalves, Y.; Reyes-Lugo, M.; Gordicho, Vasco; Ribolla, Paulo; Viveiros, BelaHistorically known as the yellow fever mosquito, Aedes aegypti invaded Madeira Island in 2005 and was the vector of the island's first dengue outbreak in 2012. We have studied genetic variation at 16 microsatellites and two mitochondrial DNA genes in temporal samples of Madeira Island, in order to assess the origin of the invasion and the population structure of this mosquito vector. Our results indicated at le...
Potential of Aedes aegypti populations in Madeira Island to transmit dengue and...
Rocha Seixas, Gonçalo Filipe; Jupille, Henri; Yen, Pei-Shi; Viveiros, Bela; Failloux, Anna Bella; Sousa, CABACKGROUND: Aedes spp. mosquitoes mainly transmit the arboviruses dengue virus (DENV) and chikungunya virus (CHIKV) in urban areas, causing a severe public health problem. In 2012-2013, a major dengue outbreak occurred on Madeira Island where the mosquito Aedes aegypti was the only vector. Up to now, the competence of Ae. aegypti populations from Madeira to transmit DENV or CHIKV remains unknown. This study aim...
The study of arboviroses transmitted by vectors in IHMT = O estudo das arboviro...
Parreira, R; Sousa, CAThe study of vector-borne diseases has always been an area of interest of the Instituto do Higiene do Medicina Tropical (IHMT). After the eradication of malaria in Portugal, the activity of IHMT in this field of knowledge focused mainly on the study of these diseases in tropi- cal and subtropical regions. However with the (re)emergence of some of these illnesses at global level, including arboviroses such as th...
