What is Chikungunya ?

Chikungunya virus is transmitted from human to human by the bites of infected female mosquitoes This virus is an  insect-borne virus , of the genus  Alphavirus, that is transmitted to humans by virus-carrying  Aedes mosquitoes ( Aedes aegypti and Aedes albopictus, two species which can also transmit other mosquito-borne viruses, including dengue). It causes an illness with symptoms similar to  dengue fever . CHIKV manifests itself with an acute  febrile  phase of the illness lasting only two to five days, followed by a prolonged  arthralgic disease that affects the joints of the extremities.

It was first detected in 1952 in Africa at a place called Makonde Plateau. The name "chikungunya" is from the Makonde language and its meaning is "that which bends up". This is a reference to the Chikungunya symptom where patients walk in a stooped posture due to joint pain.
