Chikungunya virus was first identified during an outbreak in *Tanzania in 1952-1953*. Its name comes from the Makonde language, meaning \"that which bends up,\" referring to the stooped posture of sufferers due to severe joint pain. It has since caused major outbreaks in Africa, Asia, and more recently, the Americas, highlighting its re-emerging global threat.
Chikungunya fever is primarily transmitted to humans through the bite of infected female *Aedes aegypti* and *Aedes albopictus* mosquitoes. These mosquitoes typically bite during the daytime. Humans become infected when bitten by an infected mosquito, and can then infect other mosquitoes if bitten while the virus is circulating in their blood.
Contagious Period: Varies by disease
