CDC issues different types of notices for international travelers. As of April 5, 2013, these definitions have been refined to make the announcements more easily understood by travelers, health-care providers, and the general public. The definitions are laid out below. They describe both levels of risk for the traveler and recommended preventive measures to take at each level of risk.

Notice Level	Action
