On occasion, the Centers for Disease Control issues travel notices, designed to inform travelers about current health issues related to specific destinations. These issues may arise from disease outbreaks, special events or gatherings, natural disasters, or other conditions that may affect travelers’ health.
- Level 1 is a Watch. A watch means that there is typical risk or slightly above baseline risk for the destination and limited impact to the traveler. A watch serves as a reminder to follow usual precautions for this destination.
- Level 2 is an Alert. An alert means that there is an increased risk in defined settings or associated with specific risk factors. Travelers visiting an area with an alert are encouraged to follow enhanced precautions during their visit.
- Level 3 is a Warning. A warning means that travelers to the area under warning are at high risk of contracting the illness/disease for which the warning was issued. Under a warning, the CDC encourages travelers to avoid all non-essential travel to an area.
