* Among the 415 patients with travel-associated cases, some information about the destination of travel was known for 299 (72.0%). These 299 patients reportedly had a total of 327 country visits during the 14-day exposure period. For the purpose of these analyses, travel to a U.S. territory was classified as international. Destinations are listed in descending order, by the number of country visits.
† Percentages in this column do not total 100% because of rounding.
§ Among the 299 patients, 18 (6.0%) reported travel to more than one country: eight patients had traveled to two countries, and 10 patients had traveled to three.
¶ U.S. outbound travel estimates are based on data from the U.S. Department of Commerce, International Trade Administration, National Travel and Tourism Office (Source: National Travel and Tourism Office. 2015 U.S. resident travel abroad. Washington, DC: US Department of Commerce, International Trade Administration, National Travel and Tourism Office; 2016. https://travel.trade.gov/outreachpages/download_data_table/2015_US_Travel_Abroad.pdf). Travel estimates were unavailable if the sample size for a particular country/year was <400 respondents. The country-specific percentages were calculated by summing the number of country visits and dividing by the outbound visits to that country during the period(s) with available data.
** Not available or applicable.
†† Each of the specified destinations (or regions) of travel in the “other” category was associated with fewer than three patients. The destinations include 28 countries not listed. For two of the country visits, only region-level data were available (i.e., the Caribbean and Scandinavia). Overall, 287 (87.8%) of the 327 visits with at least region-level data were in the Americas, including Mexico (n = 208), the Caribbean (n = 43), Central America (n = 31), and South America (n = 5). The other 40 visits (12.2%) were elsewhere in the world, including Asia (n = 29), Europe (n = 9), and Africa (n = 2).
