Travel Notice Definitions

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
Level 1: Watch	Reminder to follow usual precautions for this destination, as described in the Travel Notice and/or on CDC’s Travelers’ Health website. Following usual precautions, including being up to date on all recommended vaccines and practicing appropriate mosquito avoidance, is the best possible protection against this identified increased risk.
Level 2: Alert	Follow enhanced precautions for this destination. Travel Notice describes additional precautions added, or defines a specific at-risk population, to protect against this identified increased risk.
Level 3: Warning	Avoid all non-essential travel to this destination High risk to travelers, no precaution available to protect against the identified increased risk.
