"Congressional interest in and support for global health programs has remained strong for several years. In FY2017, U.S. global health funding reached an estimated $9.6 billion. These funds are managed by several U.S. agencies and the Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund)-a multilateral organization aimed at combating the three diseases worldwide. Concern about infectious diseases, especially HIV/AIDS, tuberculosis, and malaria (HTAM), continues to drive budget growth. In FY2001, roughly 47% of the U.S. global health budget was aimed at these three diseases. By FY2017, roughly 73% of the U.S. global health budget was provided for fighting HTAM."
