Surveillance of arboviruses in Spanish wetlands: detection of new flavi- and phleboviruses.

The presence of viruses in arthropods in Spain has been studied over 5 years. Flaviviruses similar to cell-fusing agent, sequences of a flavivirus related to those transmitted by mosquitoes, and a phlebovirus similar to Naples and Toscana viruses were detected. Their potential human or animal pathogenicity should be studied.
