The State Department's Office of International Health and Biodefense (IHB) addresses the relationships among human health, environmental protection, and sustainable development as they intersect with U.S. foreign policy concerns. IHB focuses on the diplomatic dimension of a broad range of environmental health and sustainable development issues such as:

  • the emergence of zoonotic diseases in an international context;
  • access to clean water and sanitation, and support for hygiene promotion;
  • the health effects from indoor air pollution due to household cooking and heating practices;
  • maternal and child environmental health.

IHB works on these issues in partnership with a wide range of stakeholders, including other Department offices, agencies across the U.S. Government, international organizations, non-governmental organizations, and private sector businesses.
