discussion on access to and delivery of antiretroviral agents in sub-Saharan Africa, as summarized in Chapter 3.
As globalization creates new governance challenges with respect to infectious disease prevention and control, the role of international law in infectious disease control policy has been shifting in important but uncertain ways.

Historically, study of the emergence of infectious diseases has been restricted to the realm of biology. The political ecology of disease provides a new conceptual framework for understanding the public health consequences of globalization, including, for example, investment decisions that lead to environmental alterations, changing vector ecologies, and increased risk of the emergence and spread of infectious diseases.

The political and economic instability of sub-Saharan African countries with high HIV infection rates, for example, threatens the potential for strong international trade partnerships and poses a serious national security risk to the United States.
Although the renewed interest in international public health can be attributed mainly to economic and national security concerns, numerous other factors are at play. One participant described this renewed interest as a convergence of economic, humanitarian, and other ideals and strategic interests, including the following:
