Overview

The United States and Mexico share a dynamic history of social, cultural, and economic ties. People travel between the United States and Mexico to visit, work, and live. Large volumes of people and products constantly move between the two countries, influencing the environment, economies, and health of people in both countries. This inter-connectedness creates binational communities of people who live throughout the United States and Mexico.

There are unique challenges and opportunities for preventing the spread of infectious diseases in the border regionA and binational communities. Public health agencies from both countries work together on shared health challenges.
