* Includes probable and laboratory-confirmed cases.
† CDCDB received a total of 529 specimens. The 596 total cases reported to ArboNET are the sum of probable (468) and confirmed (128) cases.
§ Probable is defined as a single immunoglobulin M (IgM)-positive specimen in late acute phase or convalescent phase of illness.
¶ Laboratory-confirmed results were positive by polymerase chain reaction (PCR) or viral isolation.
** If not specified otherwise, the number of cases from each country is one. Unknown indicates that no location-specific travel history was provided. Does not include travel destinations of persons with probable cases.
†† Of the 518 probable cases reported to ArboNET, 50 probable cases also were reported to CDCDB. These 50 probable cases were subtracted from the ArboNET total and included in the CDCDB total, resulting in 468 probable cases.
§§ Of 135 laboratory-confirmed cases reported to ArboNET, seven laboratory-confirmed cases also were reported to CDCDB. These seven cases were subtracted from the ArboNET total and included in the CDCDB total, resulting in 128 laboratory-confirmed cases.

* Cases were reported via ArboNET or to CDCDB; 57 cases were detected in both systems.
† Might not add to 100% because of rounding.
After the Council of State and Territorial Epidemiologists (CSTE) recommended addition of dengue to the list of nationally notifiable diseases, in January 2010, CDC added dengue to the list. Public health jurisdictions are encouraged to report cases via the ArboNET system. Health-care providers are encouraged to submit specimens to the CDC Dengue Branch for diagnostic testing, as follows:

Dengue infections commonly occur among U.S. residents returning from travel to endemic areas and are more prevalent than malaria among returning travelers from the Caribbean, South America, South Central Asia, and Southeast Asia.
During 2006–2008, an average of 244 confirmed and probable travel-associated dengue cases annually were identified by two CDC-maintained passive surveillance systems, substantially more than the 33.5 cases (range: 13–77 cases) identified annually during 1990–2005.
Health-care providers should consider dengue in the differential diagnosis of patients with a history of travel to endemic areas within 14 days of fever onset.
