Chikungunya is a viral disease transmitted by mosquitoes of the Aedes genus (especially Aedes aegypti and Aedes albopictus), present in many tropical and subtropical regions. It typically causes sudden high fever and severe joint pain that may persist for weeks or even months. There is no specific antiviral treatment, but two vaccines have been approved in certain countries. Prevention relies on protection against mosquito bites (using repellent, appropriate clothing, mosquito nets) and control of mosquito breeding sites. Vaccination may be considered for individuals at high risk of exposure. Epidemiological surveillance and early detection are key to preventing the geographic spread of the virus.
