The globalisation of the world economy and the consequent increase in
commerce, travel, and communication have brought benefits to virtually
every country. But these changes also bring risks that cannot be addr
essed adequately within traditional national borders. These risks incl
ude emerging infectious diseases, resulting in part from increased pre
valence of drug-resistant pathogens; exposure to dangerous substances,
such as contaminated foodstuffs, and banned and toxic substances; and
violence, including chemical and bioterrorist attack. By investing in
global health, industrliased countries will not only benefit populati
ons in desperate and immediate need of assistance, but also themselves
-through protecting their people, improving their economies, and advan
cing their international interests. This paper describes the rationale
for involvement of industrialised countries in global health, and sug
gests a means for its coordination.
