"The infectious agent, chikungunya virus (CHIKV), is from the Togaviridae virus family. The Aedes aegypti and Aedes albopictus mosquitoes act as the primary vectors."
"The name chikungunya is the word used by the Makonde tribal group from Tanzania to refer to the condition. It literally means “that which bends up” from the position adopted by sufferers of the disease. The ultimate derivation is from the verb 'kungunyala' which means to 'assume a contorted position'. It is interesting to note that many publications mistakenly state that its etymology descends from the Swahili language 3."
"Chikungunya fever is caused by the chikungunya virus (CHIKV), and is characterised by a classic viral prodrome of fever, skin exanthem, malaise and arthralgia. Its most striking manifestation is a marked, often fairly debilitating arthritis."
