Binational Border Infectious Disease Surveillance Program (BIDS)

Supporting local and state health departments to enhance surveillance and control of infectious diseases.

The BIDS program works closely with the four US states on the US-Mexico border to foster local, state, and federal collaboration to improve detection, reporting, and prevention of infectious diseases of binational importance. BIDS program also partners with the US-Mexico Border Health Commissionexternal icon, an organization committed to providing international leadership to improve the health and quality of life along the US-Mexico border. In alignment with the Global Health Security Agendaexternal icon, BIDS projects address a wide range of diseases including COVID-19, influenza, tuberculosis, and vector-borne and foodborne diseases.

BIDS program’s goals:

Funding Recipients

CDC’s Division of Global Migration and Quarantine funds projects that align with the BIDS Program’s goals. State and local public health agency recipients can address unique epidemiologic and communication needs of the diverse and dynamic border region. CDC also provides technical assistance to funding recipients and facilitates coordination with the Mexican Ministry of Health.

BIDS Activities

BIDS partners implement and enhance surveillance, communication, and preparedness to identify and report binational disease cases, notify public health partners about shared cases, and exchange epidemiologic information.


Surveillance activities are tailored to local disease control priorities. BIDS partners may also conduct special projects to inform surveillance needs.

Examples include:

  • Surveillance for respiratory illnesses, including influenza and COVID-19, in border communities and border-crossing populations.
  • Conducting surveys at US-Mexico land ports of entry to understand border crossers’ mobility patterns, as well as knowledge, attitudes, and practices related to COVID-19 and other diseases.
  • Incorporating the binational variable pdf icon[PDF, 88K, 5 pages]external icon into surveillance databases for reportable conditions, which flags cases of disease related to Mexico that may require binational notification or coordination.
  • Investigation of binational contacts for tuberculosis cases in Imperial County, CA, and Mexicali, Baja California, Mexico.

Communication and Preparedness

The BIDS program promotes systematic communication among partners and preparedness for infectious disease outbreaks. These activities prepare BIDS partners to detect and respond to illnesses and events of binational significance.

Examples include:

BIDS Past to Present

US and Mexican federal health authorities have been collaborating since 1999 to detect and monitor infectious diseases along the US-Mexico border. Since then, the BIDS program has evolved to address changing epidemiological and laboratory priorities.
