[Infections due to Toscana virus, West Nile virus, and other arboviruses of interest in Europe].
Arbovirosis, viral infection transmitted by arthropods, is a widespread health problem. Recurrent outbreaks caused by some of these viruses such as dengue or West Nile strains in regions where they do not appear frequently, justify the establishment of global control measures. Tick-borne encephalitis viruses, sand fly fever viruses (Toscana, Naples and Sicily) and occasionally West Nile and Crimean-Congo fever viruses are the most frequent causes of arbovirosis in Europe, although circulation of other potentially pathogenetic viruses such as Chikungunya has also been detected. The only native arbovirosis described in Spain is infection produced by Toscana virus, which causes aseptic, usually benign meningitis. Nevertheless, some West Nile virus-associated meningo-encephalitis cases have been described in France, Portugal and countries in the Magreb region, increasing the risk of sporadic occurrence of these processes in our country. To achieve an accurate diagnosis, high clinical suspicion is required as well as highly specific laboratory techniques, mainly based on IgM detection, RT-PCR and viral culture of CSF and/or serum.
