About Binational Health

*The border region includes the area 100km (62 miles) north and south of the 2000-mile-long land border. Note: Mobility arrows are for illustrative purposes and do not denote actual origins, crossing points, or destinations.

Infectious diseases know no borders. People come and go between the United States and Mexico to visit, work, and live. The movement of people and products between the two countries creates a unique binational environment for preventing and controlling diseases spread through food and water, from insects or animals, and between people.
