With increased movement of populations across borders and ever-expanding trade between countries, diseases once confined to a region now can rapidly spread internationally causing health, social, and economic disruption world-wide. The health security of each nation is dependent on that of other members of the international community. Consequently, the connection between our national health security and global health security is recognized by the 2015 National Health Security Strategy, which states “In partnership with other nations, intergovernmental organizations, and public and private stakeholders, the United States will help accelerate progress toward a world safe from public health threats and will promote efforts to strengthen global health security as a national health security priority.”
The mission of the Division of International Health Security (DIHS) stems from the Pandemic and All-Hazards Preparedness Act, which calls for the ASPR to “provide leadership in international programs, initiatives, and polices that deal with public health and medical emergency preparedness and response.” DIHS fulfills this mandate for ASPR by engaging with domestic and international partners to create an all-hazards approach to improve our collective capabilities for managing public health emergencies, including those that arise from chemical, biological, radiological and nuclear (CBRN) threats, outbreaks of emerging infectious diseases, and natural disasters. Accordingly, DIHS leads international programs, initiatives and policies to strengthen public health and medical emergency preparedness and response for events with a domestic and international interface.
