[Surveillance of the dengue vector at its distribution limit. A collaborative experience between the scientific, municipal and citizen ambits].

Introduction: In Argentina, during the last decade a southward expansion of the mosquito Aedes aegypti has been observed, accompanied by an expansion in the dengue transmission. The objective of this study was to assess the establishment of the dengue mosquito vector in a locality next to its distribution limits by a collaborative work among scientific, municipal and citizen ambits.

Methods: A vector surveillance system through ovitraps was implemented, and it was complemented by pictures and mosquitoes captured by citizens, and by the active search of breeding sites in different urban spaces of Tandil City, Argentina.
