Early determination of the reproductive number for vector‐borne diseases: the case of dengue in Brazil
TLDR
A new method of deriving the reproductive number for vector-borne diseases from the early epidemic curves for vector‐borne diseases with incubations in the vectors and in the hosts is evaluated.
Associations between dengue and combinations of weather factors in a city in the Brazilian Amazon.
TLDR
Climate-based multivariate temporal stochastic analyses have the potential to identify periods of elevated dengue incidence, and they should be integrated into local control programs for vector-transmitted diseases.
On the possibility of autochthonous Chagas disease in Roraima, Amazon region, Brazil, 2000-2001.
TLDR
Results show that Chagas disease is not endemic in the areas studied, however, all elements of the transmission cycle are present, demanding for an adequate and continuous vigilance.
Affinity and diversity indices for anopheline immature forms.
As for the entire Amazon Region, malaria continues to be a major health public problem in Roraima that presented an Annual Parasitic Index of 85.4 in 2005, the highest in Brazil. Information on…
Distribution summaries of malaria vectors in the northern Brazilian Amazon
ABSTRACT Knowledge of vector distribution is important for the design of effective local malaria control programs. Here we apply ecological niche modeling to analyze and predict the distributions of…
Preliminary assays indicate that Antonia ovata (Loganiaceae) and Derris amazonica (Papilionaceae), ichthyotoxic plants used for fishing in Roraima, Brazil, have an insecticide effect on Lutzomyia…
TLDR
Laboratory-reared Lutzomyia longipalpis was tested with extracts of two ichthyotoxic plants, known as timbós, used as fishing poison in the Amazon, and preliminary assays indicated that A. ovata and D. amazonica displayed significant insecticide effect against L. longipalPis.
A Triatoma maculata (Hemiptera, Reduviidae, Triatominae) population from Roraima, Amazon region, Brazil, has some bionomic characteristics of a potential Chagas disease vector.
TLDR
To investigate the possibility of T. maculata to possess the potentiality to transmit T. cruzi, bionomic characteristics were studied under laboratory conditions and it is shown that the Passarão population ofT.maculata should be considered a potential vector of T., cruzi.
An ecoregional classification for the state of Roraima, Brazil: the importance of landscape in malaria biology.
TLDR
An ecological classification of the state of Roraima, Brazil, in the northern Amazon Basin, focused on the natural history of malaria and transmission was used, using ecological niche modeling techniques to develop a fine-scale picture of malaria vector distributions in the state.
Parity and age composition for Anopheles darlingi Root (Diptera: Culicidae) and Anopheles albitarsis Lynch-Arribálzaga (Diptera: Culicidae) of the northern Amazon Basin, Brazil
TLDR
Investigation on longitudinal spatiotemporal change in longevity and survival rates would help clarify differences in vector competence for An.
Exploratory Temporal and Spatial Distribution Analysis of Dengue Notifications in Boa Vista, Roraima,
In Brazil, as in the rest of the world, dengue has become the most important arthropod-borne viral disease of public health significance. Roraima state presented the highest dengue incidence…
