The virus’s name, taken from the Makonde language of south-central Africa, refers to the common effect it has of causing sufferers to “bend over” in pain. The virus is carried by infected Aedes aegypti and Aedes albopictus mosquitoes, the same species that transmit dengue virus. Symptoms of chikungunya, which also include headache and muscular pain, usually appear three to seven days after a person is bitten by an infected mosquito. The disease is only rarely fatal, but the joint pain it causes can last for months or even years for some.
