Toscana virus causes unexplained encephalitis

A team from the Institut Pasteur in Paris, in collaboration with researchers in Spain, has identified Toscana virus in samples taken from patients in southern Spain.

The presence of this virus in the samples challenges the assumption that it was rare in the Mediterranean region. Thanks to this discovery, doctors can take a more effective approach to the diagnosis of encephalitis.
