Chikungunya virus infection in Italy: epidemiology, climate change implications and public health recommendations

Chikungunya is an emerging public health threat in Europe, driven by climate change, vector expansion and international travel. Italy has recently experienced an increasing proportion of autochthonous cases, highlighting gaps in surveillance, prevention and preparedness. Recent national and regional data, including those from Apulia Region, confirm ongoing transmission risk in receptive areas. Integrated surveillance, vector control, risk communication and targeted vaccination strategies are available, although unevenly implemented. This policy brief evaluates current evidence and outlines actionable recommendations to support timely decision-making and reduce the risk of local Chikungunya outbreaks.
