“…The introduction of DENV in Córdoba city and the occurrence of Based on a previous study, the survival of Ae. aegypti in Argentina was estimated to be 15 days (Carbajo et al 2001), then autochthonous dengue transmission might be expect to be limited by RND values higher than fifteen. At higher values, virus extrinsic incubation period could not be completed before mosquito death.…”

“…Previous research has demonstrated that GIS is an effective tool for the delineation of areas at increased risk of vector-borne disease outbreaks, including Lyme disease (Nicholson & Mather 1996) and malaria (Martin et al 2002). Additionally, dengue risk maps have been developed using GIS at the global scale (Hopp & Foley 2003), as well as for Argentina (Carbajo et al 2001) and New Zealand (de Wet et al 2001). Finally, Napier (2003) developed a risk model and map for Hawaii using GIS with a different approach and different variables than those included here.…”

Climate variability brought about by the El Niño-Southern Oscillation has been linked to outbreaks of infectious diseases, such as hantavirus pulmonary syndrome, cholera, and malaria. Additionally, climate change affects the distribution of diseases, causing some regions to become more or less favorable for the transmission of certain pathogens. Mosquitoes in particular are sensitive to climate change, and mosquito-borne diseases may become more common at higher latitudes and elevations under warmer conditions. This study examined the potential changes in dengue risk in Hawaii, USA, in response to climate variability and change using GIS. Dengue, transmitted by mosquitoes of the genus Aedes, is considered to be an emerging disease and almost half of the world's population is at risk of infection. Previous research has identified mosquito habitat and potential dengue risk areas in Hawaii based on average climate conditions, and this study incorporated notions of climate variability and change to that model and determined the population at risk under different scenarios. Dengue risk areas generally contract during El Niño-induced droughts and expand as a result of increased precipitation received during La Niña events. Future climate scenarios predict warmer temperatures and wetter summers in Hawaii over the next 25 yr, which will cause an expansion of mosquito habitat and potential dengue risk areas. The results of this study contribute to the overall understanding of climate-dengue relationships and will aid public health officials in efforts to determine where to concentrate resources for mosquito and dengue surveillance, given certain current or forecast climate conditions.

DHF appears to be linked to subsequent infection with a different strain of the virus (Guzman & Kouri 2002), making prevention and control of dengue in Hawaii of critical importance; those infected during the 2001-2002 outbreak could be at increased risk of contracting DHF should a different strain of the virus be introduced. A global resurgence of dengue and DHF has occurred over the past 3 decades as the range of the mosquito vector has expanded and the virus has been transferred to a greater number of locations. One factor that has been implicated in the emergence of dengue is climate variability and change (Morse 1995, Gagnon et al. 2001.While other st...

“…The increasing transmission of dengue in Brazil, Bolivia and Paraguay has been related to epidemics in Northern Argentina 2 . Misiones, Formosa and Salta have been the most affected provinces and are located in high-risk zones for dengue transmission in Argentina 2 . In the absence of a vaccine and clinical cures, control of dengue will continue to depend on the reduction of Aedes aegypti populations and mosquito interactions with humans.…”
