Two months into 2015 and there has been 43 cases of chik in travelers coming back to the US. These cases have been peppered across the US (see figure) but the majority have been in Florida (n=12) and New York (n=9). I have not seen where these cases were identified to their origin. There has been one local case in the US Virgin Islands so we can assume it is established there.
Cases, outside the US
Costa Rica: 121
El Salvador 138,617
French Guiana 12,308
Puerto Rico 24,281
Antigua + Barbados + Cayman + Jamaica 5000
So here's a prediction: we'll see a spike next month as spring breakers go down to the islands to escape the heat and Florida thaws.
Fun, fun, fun.
