Globalization and health.

Globalization means different things to different people; a general definition is the increasing movement of information, material and people across borders. It can be considered in terms of five conflicting but inter-relating themes, economic transformation; new patterns of trade; an increasing poverty gap associated with widening health inequalities; the revolution in electronic communication; and the growing role of non-state actors, such as non-governmental organizations and transnational corporations, in global governance. Globalization is both an opportunity and a threat, but it is not inexorable. Successful action against its undesirable aspects is possible.
