Protective Practices and Respiratory Illness Among US Travelers to the 2009 Hajj

Abstract

Recommended protective behaviors were associated with less respiratory illness among US travelers to the 2009 Hajj. Influenza A(H1N1) communication and education in KSA during the Hajj may also have been an effective component of efforts to mitigate illness. Evaluations of communication efforts and preventive measures are important in developing evidence-based public health plans to prevent and mitigate disease outbreaks at the Hajj and other mass gatherings.
