About the Division of International Health Security

The interconnectedness of our world brings with it the ability for emerging infectious diseases and other health security threats to spread rapidly across borders. To better protect health and save lives, the Division of International Health Security coordinates with its partners across the country and around the globe to enact plans, policies and response strategies that help mitigate these threats.

What we do

DIHS provides leadership on a variety of multilateral and bilateral engagements designed to strengthen the health security of U.S. and international partners and foster domestic and international collaboration on public health preparedness and response. These include the Global Health Security Initiative (GHSI), the North American Plan for Animal and Pandemic Influenza (NAPAPI), binational health security issues under the Canada-U.S. Beyond the Border Initiative and other bilateral engagements.

DIHS develops policies and plans for HHS to provide and receive international assistance and for coordination of public health emergency responses at the domestic-international interface, integrating national and international activities and stakeholders. DIHS leads the implementation of these policies and plans during public health emergencies that have both national and international implications, with a focus on sharing of public health and medical assets, such as medical countermeasures, laboratory specimens, and medical and public health personnel.

Under the U.S, binding commitment to the World Health Organization’s (WHO) International Health Regulations (IHR), DIHS manages the U.S.IHR National Focal Point (NFP) and leads all policy aspects of notifications of public health emergencies of international concern (PHEIC) to WHO.  In addition, DIHS leads the monitoring and evaluation of the U.S.’s implementation of its capacities to detect, prevent and respond to public health emergencies, including leading the self-assessment and coordination of the external, independent evaluation of our country’s capacities under the IHR Joint External Evaluation (JEE) framework, assigned to HHS under the Executive Order for Advancing the Global Health Security Agenda to Achieve a World Safe and Secure from Infectious Disease Threats

DIHS also collaborates with domestic and international partners through strategic programs to support implementation of IHR core capacities in partner countries, including strengthening of NFP capacities and preparedness planning for response to public health emergencies.


*The DIHS mission stems from a legislative mandate in the Pandemic and All-Hazards Preparedness Act (PAHPA), Public Law 109-417.

Health Security in an Interconnected World
