BACKGROUND Rio de Janeiro, Brazil, experienced a severe dengue fever epidemic in 2008. This was the worst epidemic ever, characterized by a sharp increase in case-fatality rate, mainly among younger individuals. A combination of factors, such as climate, mosquito abundance, buildup of the susceptible population, or viral evolution, could explain the(More)
The spatial distribution of Aedes aegypti and Aedes albopictus in a transition zone, Rio de Janeiro, Brazil Padrões da distribuição espacial do Aedes aegypti e Aedes albopictus em uma zona de transição no Rio de Janeiro, Brasil Abstract Dengue fever has become the most important vector-borne viral disease in Brazil. Human facilitated transport of(More)
Freqüência e distribuição espacial de Aedes aegypti e Aedes albopictus (Diptera, Culicidae) no Rio de Janeiro, Brasil Frequency and spatial distribution of Aedes aegypti and Aedes albopictus (Diptera, Culicidae) Abstract We evaluated the intra-and peri-domiciliary distribution of Aedes aegypti and Ae. albopic-tus in urban, suburban, and rural districts in(More)
We performed a longitudinal study of adult survival of Anopheles darlingi, the most important vector in the Amazon, in a malarigenous frontier zone of Brazil. Survival rates were determined from both parous rates and multiparous dissections. Anopheles darlingi human biting rates, daily survival rates and expectation of life where higher in the dry season,(More)
INTRODUCTION The mosquito Aedes aegypti, vector of dengue, chikungunya and yellow fever viruses, is an important target of vector control programs in tropical countries. Most mosquito surveillance programs are still based on the traditional household larval surveys, despite the availability of new trapping devices. We report the results of a multicentric(More)
Aedes aegypti and Ae. albopictus are vectors of dengue viruses, which cause endemic disease in the city of Manaus, capital of the state of Amazonas, Brazil. More than 53 thousand cases have been registered in this city since the first epidemic in 1998. We evaluated the hypothesis that different ecological conditions result in different patterns of vector(More)
This paper describes the RobChair assistive navigation system. RobChair project was conceived with the aim to assist disabled people in the difficult task of manoeuvring a powered wheelchair. This paper describes the overall hardware and software architecture including the communication system; a friendly Graphical User Interface (GUI) which also works as a(More)
We analyzed factors associated with severe cases of dengue in children and adolescents hospitalized during the 2007/2008 epidemic in Rio de Janeiro, Brazil. This is a retrospective case-control study that covers 88 cases of severe dengue in patients admitted to four tertiary care children's hospitals. Controls consisted of 22 children with non-severe dengue(More)
Fish farming in the Amazon has been stimulated as a solution to increase economic development. However, poorly managed fish ponds have been sometimes associated with the presence of Anopheles spp. and consequently, with malaria transmission. In this study, we analyzed the spatial and temporal dynamics of malaria in the state of Acre (and more closely within(More)
