Long considered a tropical disease confined to certain regions of Africa and Asia, chikungunya has undergone a concerning expansion in recent years. Primarily transmitted by Aedes aegypti and Aedes albopictus mosquitoes, the virus causes an acute febrile illness often accompanied by severe joint pain that can persist for months or even years in some patients. While major outbreaks were once relatively sporadic, both the number of epidemics and their geographic spread are now increasing rapidly.
