West Nile Virus (WNV), an arbovirus transmitted by mosquitoes and primarily hosted by birds, represents a major public health concern in the Mediterranean region. This zoonotic disease can cause clinical manifestations ranging from mild symptoms to severe encephalitis, especially in the elderly or immunocompromised individuals.
Despite the existence of surveillance systems in many Mediterranean countries, control measures remain limited due to the lack of a human vaccine and curative treatment. Prevention relies mainly on vector control and early detection of outbreaks. One of the main challenges lies in the silent circulation of the virus in endemic areas, facilitated by climate change, avian migratory flows, and the diversity of mosquito vectors. Additionally, disparities in surveillance strategies between countries make epidemic forecasting difficult.
