Situación actual en España y eco-epidemiología de las arbovirosis transmitidas por mosquitos culícidos (diptera: culicidae)

Abstract

In this manuscript we analize the possible emergence and/or re-emergence in Spain of some of the mosquito-borne arboviruses (Diptera: Culicidae) with highest incidence in recent years. The faunistic, bioecological and distributional data of the culicids in our country allow to differentiate between species with ability to maintain the enzootic cycles of arboviruses from others that can act as bridge vectors to the human population. The results show the existence of several common and anthropophilic species as Aedes vexans, Culex modestus, Culex pipiens or Ochlerotatus caspius, with a high capacity to transmit flaviviruses such as West Nile virus or Usutu virus. Moreover the recent introduction, establishment and spread of the Asian Mosquito Tiger, Aedes albopictus, propitiate a new situation for the emergence of possible epidemic outbreaks of arboviruses usually imported to our country by immigrants and tourists such as Dengue or Chikungunya. Finally we discuss the epidemiological interest of other native species as Aedes vittatus or Ochlerotatus geniculatus, due to its capacity to transmit some of these typically tropical arboviruses.
