Chikungunya is a mosquito-borne viral disease causing symptoms such as fever, joint pain, muscle pain, headache and nose and gum bleeding.
Chikungunya is present in parts of Africa, Southeast Asia and on the Indian subcontinent. The most recent large outbreaks were reported in 2005–2006 from Réunion Island, Mauritius, Mayotte and several Indian states. The first transmission within continental Europe was reported from north-eastern Italy in August 2007. Every year, imported cases among tourists are identified in several European countries.
