Chikungunya virus (CHIKV) is an arboviral (arthropod-borne) disease. In the Western Hemisphere, the cycle is currently maintained in a human-mosquito cycle. There is no other known vertebrate (animal with a spinal column or backbone) host. Clinical signs of fever and polyarthralgia (pain in many joints) typically resolve within 7–10 days. Severe clinical signs and symptoms are rare. Mortality is also rare and occurs mostly in older adults. As with other mosquito-borne diseases, avoidance of mosquito bites is the key to prevention.
