Cross-Border Health Risks
This term is used to describe risks to human health that cross national borders. Examples include risks from climate change and the illegal drugs trade, as well as cross-border movements of people, which can lead to the spread of communicable diseases such as HIV/AIDS, malaria, TB and influenza. Since 1990, global trade has grown six-fold and the number of people travelling by air has increased 17-fold. Today, more than 2 million people cross borders each day and travel times are shorter than the incubation periods of many diseases. Increasingly, a country's foreign policy may be linked to cross-border health risks.
