§ Cases were classified as travel associated or domestically acquired on the basis of the patient's travel history during the pertinent exposure period (i.e., the 14 days before illness onset). If the patient reported having a history of international travel (i.e., travel outside the United States) during all or part of the exposure period, the patient's case was classified as travel associated. If the patient reported having no history of international travel, the patient's case was classified as domestically acquired.
