Abstract

In December 2013, chikungunya virus (CHIKV) transmission was reported for the first time in the Americas. Since then it has spread quickly, with more than 1 million suspected and confirmed cases being reported in one year, where previously there were only sporadic travel-related cases. Transmission patterns suggest that the epidemic in the southern hemisphere is only beginning and that chikungunya will not go away anytime soon.

Chikungunya cases reported by month. Red bars indicate the number of cases reported each month including suspected and confirmed, imported and autochthonous cases. Orange bars indicate the cumulative number of countries or territories reporting autochthonous cases. Data were compiled from Pan American Health Organization reports (http://www.paho.org/chikungunya) using cumulative reports published closest to the end of each month. *The US includes cases in Puerto Rico and the US Virgin Islands where large outbreaks are ongoing.
