United States - Mexico Unit
El Paso and San Diego Quarantine Stations
The U.S. Centers for Disease Control and Prevention (CDC) established the U.S.–Mexico Unit (USMU) in the Division of Global Migration and Quarantine (DGMQ) in 2009. The Unit was created to enhance collaboration between the United States and Mexico on binational public health issues and events of mutual concern. USMU serves as CDC’s official liaison with the Mexico Secretariat of Health.
The Unit implements CDC programs that focus on the U.S.–Mexico border, including managing CDC Quarantine Stations in El Paso and San Diego and conducting binational infectious disease surveillance projects.
USMU staff are located at or work with state and local health departments in El Paso, Texas; and San Diego, California. Additional DGMQ staff are assigned to the Unit to help with other CDC programs.
The USMU quarantine jurisdiction includes all ports of entry in Arizona, New Mexico, San Diego and Imperial Counties in Southern California, and South and West Texas (Health Districts 8–11). This includes the seaports of San Diego; Port Isabel and Corpus Christi, Texas; and the U.S.–Mexico land border crossings and international airports.
Quarantine Station Activities
- Respond to reports of illness at land border crossings, international airports, and on maritime vessels (cruise and cargo).
- Review medical records of migrants who will reside permanently in the United States. Notify state and local health departments of any migrants with specific medical conditions that need prompt evaluation or treatment.
- Assist cross-border, tuberculosis (TB) patients with continuity of treatment.
Binational Communication and Partnership
- Facilitate high level public health communication between CDC and Mexico Secretariat of Health.
- Communicate among U.S. and Mexico public health officials and humanitarian agencies.
- Detect, notify, and investigate communicable disease cases with partner health officials and border protection agencies in the United States and Mexico.
- Help coordinate binational response to outbreak investigations and other public health events affecting the U.S.–Mexico border region.
- Collaborate and help support binational surveillance and disease control projects, such as Border Infectious Disease Surveillance (BIDS) and binational TB projects (Cure-TB, TB-Net, Project Juntos).
- Provide technical assistance and subject matter expertise to U.S.–Mexico federal and state agencies on binational infectious disease issues.
Research and Preparedness
- Conduct public health research on food-borne, vaccine preventable, and vector-borne diseases that affect cross-border populations.
- Partner with other U.S. federal agencies and local and state health departments in preparedness activities related to quarantine and isolation at international ports of entry.
