Chikungunya fever (CHIK) is an emerging viral disease. It is caused by the Chikungunya virus, an alphavirus from the Togaviridae family. It is transmitted to humans by the bite of infected mosquitoes, mainly Aedes aegypti and Aedes albopictus. They are also involved in the transmission of dengue, malaria, etc. CHIK is now endemic in any region of Africa and Southeast-Asia. Cases of CHIK have been reported in America, the Caribbean, and Europe (France, Italy and Spain). There are reservoirs of these mosquitoes in some regions of Spain (Catalonia, Alicante, Murcia and Balearic islands). CHIK is characterized by a sudden high and debilitating fever, and severe or disabling symmetrical arthralgia. It tends to improve in days or weeks. There are severe and chronic forms of CHIK. There is no specific treatment or prophylaxis for CHIK. An algorithm is proposed for the clinical management of CHIK based in the latest guidelines.
