Spain: Chikungunya

17 June 2019

Spain: Chikungunya

The Spanish health authorities confirmed (by media, in Spanish) three cases of chikungunya in Alicante.


The three people live in Iceland and were diagnosed after their return from Spain.


Another possible case of a family member living in Norway is currently under investigation.


In southern Europe, chikungunya is transmitted by the Asian tiger mosquito Aedes albopictus.


Chikungunya is a disease caused by a virus (arbovirus) transmitted by mosquitoes. The name of this zoonosis (animal disease transmissible to humans) means Makonde "walk bent", describing the attitude of people with the virus. These mosquitoes are diurnal with a peak of activity at the beginning and end of the day. The mosquito takes the virus by pricking a person with the disease during the viraemia phase and becomes infected. In another sting, he can transmit the virus to a healthy person.


In case of sudden onset of fever associated possibly with headaches, muscle and joint pain, it is necessary to consult a doctor to clarify the diagnosis and be prescribed appropriate drugs. Indeed, some drugs, especially anti-inflammatories, may be contraindicated (especially in pregnant women) or must be the precaution of use and a suitable dosage in children.


The onset of these symptoms within 12 days of leaving an area where the chikungunya circulates requires consulting a doctor specifying the destination and dates of stay. Remember that it is imperative to protect against mosquito bites during the stay but also on the occasion of the return if the symptoms appear, so as to avoid possible transmission.
