Who We Serve

Globally Mobile Populations

Globally mobile people may travel across a single country or from country to country. This movement can increase their risk of exposure to uncommon infectious diseases and can spread those diseases to different parts of the world.

Binational Populations

DGMQ works with populations who travel, live, and work around the United States and Mexico border because of the health conditions and risks that the two countries share. The movement of people and products between the US and Mexico creates a binational environment for preventing and controlling diseases spread through food and water, from insects or animals, and between people.

Mexico is the top destinationExternalexternal icon for US residents traveling internationally (39% of all foreign travel), and Mexican residents visiting the United States represent almost 25% of all international visitors.

DGMQ is focused on binational public health issues, such as

  • Infectious diseases affecting both countries, including outbreaks among people who have traveled between the United States and Mexico
  • Diseases associated with importing and distributing products within North America
  • Identification and referral of people with infectious conditions who are traveling back and forth between the United States and Mexico

Immigrants, Refugees, and Migrants

DGMQ assesses the health of people coming to live and work in the United States while also protecting the health of communities they join. DGMQ provides the technical instructions to physicians who conduct required medical screenings for immigrants, refugees, and migrants before they are admitted to the United States. During these required medical exams, individuals receive vaccinations as well as treatment needed to ensure that certain health conditions are treated before their arrival.

DGMQ works to improve the health of immigrants, US-bound refugees, and migrants through programs that

  • Track disease outbreaks to learn about diseases of concerns in immigrants and refugees. For example, with tuberculosis and vaccine-preventable diseases, figure out how and where they spread and how to stop them from spreading
  • Develop guidelines to respond to disease outbreaks and other health events affecting US-bound immigrants and refugees
  • Build capacity for healthcare partners to diagnose and treat diseases and strengthen international partnerships that also build this capacity
  • Develop guidelines for clinicians who care for immigrants and refugees after they arrive in the United States

Today, around the world, DGMQ partners with

  • >600 physicians performing required immigration medical examinations outside the United States
  • 5,000 physicians performing required immigration medical examinations in the United States
