With a total of 623 travel associated and locally acquired chikungunya cases, three states account for slightly more than half of all chikungunya cases in the United States, according to the latest data from the Centers for Disease Control and Prevention (CDC) Wednesday.


New York (274), New Jersey (109) and Florida (240 travel associated and local transmission) account for some 51 percent of the 1,211 cases reported nationally.

Florida has reported 11 indigenous chikungunya cases to date, the only such cases reported in the United States so far.

The travel associated cases are reportedly from the Americas (1,184), the Pacific Islands (8), or Asia (8).

The only states without a reported chikungunya case include Montana, North Dakota, Wyoming and Alaska. According to the Pan American Health Organization, Canada has seen 8 imported cases as of last Friday.

From 2006‒2013, studies identified an average of 28 people per year in the United States with positive tests for recent chikungunya virus infection (Range 5‒65 per year). All were travelers visiting or returning to the United States from affected areas, mostly in Asia.

Since the first locally acquired chikingunya cases were reported in the Western hemisphere in December 2013, some 750,000 chikungunya cases have been reported from North, Central and South America. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
