Surveillance and Spatial Characterization of Aedes aegypti in Sint Eustatius, Netherlands Antilles
Abstract
Dengue, an arbovirus transmitted by Aedes mosquitoes, threatens over 40% of the worlds population. In Latin America and the Caribbean the incidence and severity of disease has increased rapidly in recent years. On the island of Sint Eustatius, a Caribbean island in the Netherlands Antilles, it has been over 65 years since the last known entomological survey. This study was designed to characterize the domestic distribution of adult and larval Ae. Aegypti and identify potential risk factors for the distribution of Ae. Aegypti and dengue infections in Sint Eustatius. Surveys were completed using Prokopack aspiration, BioGents-Sentinel (trademark) mosquito trap, and sampling of larval positive containers. Over 75 percent of the homes surveyed were positive for Ae. aegypti. There were statistically significant positive linear correlations between Prokopack aspiration indoors and BioGents-Sentinel mosquito traps outdoors, while nolinear correlation existed with either and larval surveys. Garbage related and domestic use containers contributed 95%of the sample larvae sampled, while homes with outdoor and window screens contributed to 82%of the sampled adults. There were no dengue positive mosquito pools identified with qPCR for the study period of June-August 2012.
