In the rush of Ebola news, it's easy to forget that chikungunya is a much more clear and present danger to the western hemisphere. On September 26 the Pan American Health Organization published its latest update, and the numbers continue to look bad.
All told, PAHO counts 737,084 "suspected" cases in the Americas as of week 40, but this number is likely a serious undercount. Even the US is updated only to week 39. Incredibly, Haiti seems not to have reported since week 28, when it reported just 65,695 cases. The Dominican Republic, as of week 38, had 486,306.
On the mainland, El Salvador at week 36 had 16,389 cases, while Colombia (week 39) had 4,619. Islands in the "Latin Caribbean" continue to report high numbers: Guadeloupe (78,120), Martinique (64,250), and Puerto Rico (7,306).
The impact on trade, travel and tourism in the Caribbean is going to be serious, especially this winter.
