[Imported fever due to Chikungunya virus].

Introduction: Imported diseases pose a diagnostic challenge for the physician, epidemiologists, and the local health care authorities, implying a risk for the community in some cases.

Method: We report the case of a patient with Chikungunya virus infection in Spain and describe the clinical and epidemiological characteristics of this condition.

Results: Diagnosis was confirmed by specific tests in paired samples.

Conclusions: The vector for the disease (Aedes albopictus) now exists in Spain. There is a danger that local outbreaks may occur where there are patients with viremia in areas with a prevalence of the vector.
