Since human migrations began, germs have traveled with people, animals and traded goods. In an interconnected and mobile world, diseases such as HIV/AIDS and SARS can spread rapidly. Yet international cooperation through agencies such as the World Health Organization also allows for a collective response to global health threats and faster response times. Nations have developed diverse health care systems, aiming for cost-effective treatment.
