Terms to know

Migration is the movement of people for different reasons from where they usually live to another place within a country or across an international border.

Border health focuses on populations moving across borders within and between countries, and the communities they are in before, during, and after travel. It also includes closely connected communities on both sides of an international border. The aim of border health is to limit the geographic spread of health threats.

What CDC is doing

CDC experts work in the United States and abroad to apply the best science to protect people from the international spread of infectious diseases. Working with government and non-government partners globally, CDC helps develop public health capacity in border areas and at points of entry (POEs), including international airports, ports, and ground crossings. This technical assistance also helps build capacities in national or regional public health systems to better address mobile populations.
