“…The whole envelope gene (1435 bp) of DENV-4-positive isolates recorded in the study was also amplified as two fragments using two primer pairs, D4742/D4CP1838 and D41236/D4CP2536 (Lanciotti et al, 1997) to determine the genotypic evolution of this rare serotype in India. The protocol followed was modified from that described by Lanciotti et al (1997). The one envelope gene and all 29 CprM gene sequences generated in the study were submitted to GenBank.…”

“…The alphaviruses (except CHIKV) produced a 434 bp fragment and the flaviviruses produced a 958 bp fragment, whilst CHIKV produced a 354 bp fragment (Hasebe et al, 2002). The flavivirus-positive 958 bp fragment was further processed by amplification of the capsid premembrane (CprM) gene (~511 bp) using the DNA primers D1 and D2 reported for DENV (Lanciotti et al, 1992) to check for dengue infection status, following the protocol of Lanciotti et al (1997).…”

“…Unlike other RNA viruses, some segments of the dengue virus genome have a high degree of stability where fixed mutations are common. Partial sequencing of some genomic regions has been successfully employed to determine the genetic variation of dengue viruses and to characterize genotypes within serotypes (6)(7)(8)(9)(10)(11).…”

“…For four years prior to this, DENV-1 was spreading throughout the Caribbean Islands, Central America and Northern South America (Moros et al 2003, Uzcategui et al 2003. The year 1981 also marked the arrival of DENV-4 in the Americas (Lanciotti et al 1997). In Boa Vista, this first invasion was interrupted through vector control programs and the country was spared any new dengue invasions until 1986, when DENV-1 arrived in Rio de Janeiro, triggering nationwide epidemics (Nogueira et al 2007).…”

The highest infestation rates occurred during the peak of the rainy seasons, but a large presence was also observed during the early dry season (although with more variation among years). Spatial distribution of positive houses changed from a sparse and local pattern to a very dense pattern during the dry-wet season transition. These results suggest that the risk of dengue transmission and the potential for the new serotype invasions are high for most of the year.Key words: Aedes aegypti -dengue fever -ovitraps -seasonality -Amazon Separated from the rest of country by the Amazonian Forest, Roraima (RR) is the most isolated state in Brazil. Boa Vista, its capital, is a medium-sized city (249,853 inhabitants) (IBGE 2008a) located in the middle of a sparsely populated savannah. A highway is the only paved interstate route, connecting Boa Vista to the city of Manaus 805 km to the south and the Venezuelan border 220 km to the north. Despite its isolation, Boa Vista (and RR as a whole) has received -and continues to receive -a large inflow of visitors and migrants from Venezuela, Guyana and the Caribbean countries, as well as migrants from other regions of Brazil. As a consequence, RR's population increased from 79,400 inhabitants in 1980 to 395,725 inhabitants in 2008, a 5-fold increase in fewer than 30 years. Today, 53.7% of RR's population are immigrants, the highest proportion observed in Brazil (IBGEb 2008).The first dengue fever epidemic in Brazil after the re-invasion by Aedes aegypti occurred in Boa Vista in 1981-1982 with 11,000 reported cases (Osanai et al. 1983, Travassos-da-Rosa et al. 1998. DENV-1 and DENV-4 were isolated. For four years prior to this, DENV-1 was spreading throughout the Caribbean Islands, Central America and Northern South America (Moros et al. 2003, Uzcategui et al. 2003. The year 1981 also marked the arrival of DENV-4 in the Americas (Lanciotti et al. 1997). In Boa Vista, this first invasion was interrupted through vector control programs and the country was spared any new dengue invasions until 1986, when DENV-1 arrived in Rio de Janeiro, triggering nationwide epidemics (Nogueira et al. 2007). Dengue fever has become an endemic disease in Brazil, with the cocirculation of DENV-1, DENV-2 and DENV-3 in most of the 27 Brazilian states. DENV-4 did not persist in Brazil after RR's 1981-1982 outbreak (Nogueira et al. 2007). For several years now, RR has consistently had one of the highest dengue incidence rates among Brazilian states. In 2007, RR registered an incidence rate of 594.8 cases per 10,000 inhabitants. This was the highest rate after Amapá (877.7), Tocantins (TO) (1415.3) and Mato Grosso do Sul (MS) (3213). In 2006, the incidence rate in RR was 657.8, highest after MS (688.3) and TO (665.7) (MS 2007).Ae. aegypti in Boa Vista, RR • Cláudia Torres Codeço et al. 615Its proximity to Venezuela, where all four dengue serotypes are found, and appropriate vector and climate conditions for dengue transmission, make Boa Vista a strategic point for dengue surveillance in Brazil.
