Chikungunya virus disease
Chikungunya is a viral disease transmitted by Aedes mosquitoes to humans. The word ‘chikungunya’ means 'that which bends up', an allusion to the posture of the suffering patients. The most common clinical form associates fever, arthralgia and rash. Recovery is the usual outcome but chronic arthritis is not rare. Diagnostic tests are available but there is no antiviral treatment or licensed vaccine. The disease is notifiable at EU level.
The risk of the chikungunya virus spreading in EU is high due to importation through infected travellers, presence of competent vectors in many countries (particularly around the Mediterranean coast) and population susceptibility. Read more in the factsheet on chikungunya
Prevention and control
The best protection against mosquito-borne diseases is preventing mosquito bites. Control measures include strengthening mosquito surveillance in areas in Europe at risk of importation of mosquitoes and virus transmission.
