The Transportation Security Administration (TSA) was created in the wake of 9/11 to strengthen the security of the nation’s transportation systems while ensuring the freedom of movement for people and commerce. Within a year, TSA assumed responsibility for security at the nation’s airports and deployed a federal workforce to screen all commercial airline passengers and baggage. In March 2003, TSA transitioned from the Department of Transportation to the Department of Homeland Security.
TSA is committed to evolving its systems to enhance the safety of the traveling public as well as individual passenger experiences whenever possible.
Center of Disease Control
The CDC maintains a department that is concerned with travelers health.
CDC issues different types of notices for international travelers. We are refining these definitions to make the announcements more easily understood by travelers, health-care providers, and the general public. In addition, defining and describing levels of risk for the traveler will clarify the need for the recommended preventive measures. From the public health perspective, scalable definitions will enhance the usefulness of the travel notices, enabling them to be tailored readily in response to events and circumstances.
