title: Chikungunya fever.
abstract: Chikungunya fever (CF) is an acute illness caused by Chikungunya virus (CHIKV) belonging to the alphavirus genus of the Alphaviruses (Togaviridae) family. The virus is transmitted by Aedes mosquitoes. CF is primarily tropical disease occurring in Africa, Asia and Indian Ocean islands but in the last decade an outbreak of CHIKV autochthonous infections were reported in Italy and France. It is associated with viral genome mutations facilitating transmission of the disease by Aedes albopictus, a mosquito occurring in several European countries. The CF is highly symptomatic, characterized by fever, cutaneuos rash and severe athralgia and arthritis. In some patients severe neurological or hemorrhagic manifestations occur. The disease is self-limiting but a part of the patients suffers from a long-lasting arthritis akin to rheumatoid arthritis. Treatment is only symptomatic. Prevention includes reduction of mosquito bite (mosquito net, repellent) or application of measures against mosquito larvae. Vaccination is not currently available but investigations are in progress. CF presents a significant worldwide health problem affecting in the last decade millions of person, and currently dangerous also for European countries.
