BACKGROUND:
Aedes mosquitoes are vectors of arboviral diseases of great relevance for public health. The recent outbreaks of dengue, Zika, chikungunya and the rapid worldwide spreading of Aedes albopictus emphasize the need for improvement of vector surveillance and control. Host antibody response to mosquito salivary antigens is emerging as a relevant additional tool to directly assess vector-host contact, monitor efficacy of control interventions and evaluate risk of arboviral transmission.
METHODOLOGY/PRINCIPAL FINDINGS:

Hematophagous arthropods during feeding inject into their hosts a cocktail of salivary proteins whose main role is to allow for an effective blood meal by counteracting host hemostasis, inflammation and immunity. However, saliva of blood feeders also evokes in vertebrates an antibody response that can be used to evaluate exposure to disease vectors.
