Chikungunya rarely kills, but it can be profoundly debilitating. The hallmark symptom is severe joint pain that can persist for weeks, months, or even years after the initial infection. The name itself comes from a Makonde word meaning "to become contorted" — describing the stooped posture of sufferers.
Like dengue and Zika, chikungunya is carried by day-biting Aedes mosquitoes. It has been spreading geographically since the 2000s, with outbreaks now occurring in southern Europe (Italy, France, Spain) in addition to its traditional range across Africa, Asia, and the Americas.
There is no vaccine or antiviral treatment. Management focuses on pain relief and hydration. Elderly travelers and those with pre-existing joint conditions are at highest risk of prolonged symptoms.
Aedes aegypti and Aedes albopictus — day-biting species. The tiger mosquito (albopictus) is the primary vector in European outbreaks.
Elderly travelers, newborns, and people with chronic conditions like diabetes or heart disease. The debilitating joint pain can persist for months or years, significantly affecting quality of life.
