Ten years since the last Chikungunya virus outbreak in Italy. History repeats itself

The prevalence of Arbovirus (arthropod-borne virus) infections is increasing worldwide. Recently, new clusters of autochthonous cases have been reported in countries with temperate climates where the competent vector is present. This scenario represents a new threat for transfusion medicine.CHIKV has been a significant public health concern in Asian and African countries, where most epidemics occurred in the 1960s and 1990s, and is newly emerging in Middle East, Pacific, American, and European countries. Exactly 10 years after the first European outbreak of CHIKV, the virus has emerged again in Italy where the competent vector (Aedes albopictus) is present.
