Globalization, the flow of information, goods, capital and people across political and geographic boundaries, has helped to spread some of the deadliest infectious diseases known to humans.
Globalization is driven by economic, technological, political influences, cultural systems and values, and factors of social and natural environment. We must beware of how far-reaching changes are impacting on infectious diseases.
It should be noted that infectious diseases are a growing threat to all nations in the developed world. But it also can provide innovative mechanisms, to controlglobal infectious diseases.
In public health, a similar combination of factors of age and new can be seen. People have cooperated in the fight against infectious diseases, first through international sanitary treaties and later through the World Health Organization.
Globalization has affected public health in three ways. First, the shrinking of the world by technology and economic interdependence allows diseases to spread globally at rapid speed. Second, the development of the global market has intensified economic competition and increased pressure on governments to reduce expenditures, including the funding of public health programs, leaving states increasingly unprepared to deal with emerging disease problems. Third, public health programs have also “gone global” through WHO and health-related nongovernmental organizations.
