Sandfly fever is a febrile emerging arboviral illness which is a huge threat posed to public health. Sandfly fever viruses (Sicilian, Naples, and Toscana) are endemic to the Mediterranean region. Evidence suggests an increase in the activity of sandfly-borne phleboviruses and their extension to other places. The infection is relatively benign but may cause severe clinical manifestations and complications. Sandfly fever viruses belongs to the genus Phlebovirus (family Bunyaviridae), and the four main serotypes include sandfly fever Sicilian virus, sandfly fever Naples virus, sandfly fever Cyprus virus, and Toscana virus. Sandfly fever has flu-like symptoms such as fever, headache, photophobia, malaise, myalgia, and retro-orbital pain. The incubation period of the disease is 4-8 days, and the patient usually recovers within a week. The first infection provides the host with immunity. Sandfly fever viruses are transmitted through the bites of infected female sandflies, thus, the epidemiology of sandfly fever is closely related to the presence and activity of sandfly species that act as the vectors for transmission. Cases and outbreaks of the disease have been reported worldwide for more than 100 years. All in all, this disease is important for non-endemic countries because it is a travel-related and/or imported illness.
