Entomological surveillance with an emphasis on Aedes aegypti (Díptera: Culicidae) in displaced persons camps of Haiti, 2010-2011.

Abstract

Introduction: as a result of the earthquake occurring in Haiti in 2010, health, sanitation and environmental conditions worsened and a large number of persons lost their homes. Objective: evaluate vector surveillance with an emphasis on Aedes Aegypti in a post-earthquake displaced persons camp in the commune of Carrefour, Haiti, from June 2010 to June 2011. Methods: determination was made of the presence and density of Ae. aegypti, Anopheles albimanus and Culex quinquefasciatus by means of larval surveys. Adult control measures and larvicides against Ae. Aegypti were also used. Results: seven mosquito species were identified. The values obtained for the indices household, container and Breteau showed that Ae. aegypti densities remained stable, with an increase in the second half of the year. Most breeding sites were miscellaneous containers (56%), followed by pneumatic tires (27%). An. albimanus and Cx. quinquefasciatus showed scant presence in the study area. Adulticide treatments contributed to the control of mosquito densities at institutions with the presence of Cuban cooperation personnel and in the displaced persons camp. Conclusions: mosquito surveillance and control were permanent during the study period, as a result of which there were no reports of diseases transmitted by this vector in the displaced persons camp.
