Dengue Surveillance

Patient-based dengue virus surveillance in Aedes aegypti from Recife, Brazil.

BACKGROUND & OBJECTIVES: Dengue is currently one of the most important arthropod-borne diseases and may be caused by four different dengue virus serotypes (DENV-1 to DENV-4), transmitted mainly by Aedes aegypti (Diptera: Culicidae) mosquitoes...
