Smithsonian scientists explain spread of chikungunya vector

The tropical disease chikungunya began twisting Western tongues in July when the first locally transmitted case was reported in Florida. Spotted in the Caribbean just last year, the disease spread explosively throughout the Americas in 2014. Chikungunya’s arrival in prompted to examine how human activity spreads its and the serious implications this has for disease ecology everywhere.

Chikungunya causes fever, fatigue and joint swelling and is transmitted by the Asian , Aedes albopictus. The also spreads dengue, so the study published in PLOS Neglected Tropical Diseases also holds a cautionary tale for dengue-eradication programs, which primarily target another mosquito, the virus’s main vector, Aedes aegypti.
