New York state is now reporting 100 imported chikungunya cases, or 15 percent of the US total to date, following only Florida in the number of cases, according to the Centers for Disease Control and Prevention (CDC) yesterday.


The number of imported Chikungunya virus disease cases reported to ArboNET as of Aug. 19 is now at 636 in 43 states and the District of Columbia. This up from 580 cases last week.

The CDC numbers in Florida (138 imported, 4 locally acquired); however, do not match the numbers the Florida Department of Health reported this week. Health officials say the number of locally acquired chikungunya cases in the Sunshine State is now 171, while Palm Beach County reported two additional locally acquired cases, bringing that total to six.

The chikungunya cases in the US are linked to travel to the following countries: Anguilla, Antigua and Barbuda, Dominica, Dominican Republic, El Salvador, Guyana, Haiti, Indonesia, Martinique, Puerto Rico, Saint Barthelemy, Saint Kitts and Nevis, Saint Lucia, Saint Martin, Sint Maarten, Tonga and US Virgin Islands.

Florida health officials also reported an imported case this week linked to travel to the Philippines.

The 636 cases reported to date is significantly higher that the 28 case average reported 2006-2013 in the United States. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
