USAID’s Global Health Security program aims to strengthen the capacity of partner governments, universities and research institutions, the private sector, and civil society for the prevention, preparedness, detection, and response to infectious disease threats. Nearly 75 percent of emerging infectious diseases are a result of zoonotic pathogens (spread between animals and people), in addition to the threat of antimicrobial resistance. Recognizing the interconnection between the health of humans, wild and domestic animals, and their shared environment, USAID works across these sectors applying a One Health approach to strengthening health systems.
