The new health threats of exotic and global travel

摘要

We live in a globalised world with travel, population movements, and migration impacting virtually all countries. As a result, global infectious disease epidemiology is changing. Greater global mobility leads to the potential of importing, exporting, or spreading communicable diseases across regions, borders, and continents, potentially posing a health threat to the UK. The movement of animals, plants, and other goods across the globe, through international trade, also creates new public health challenges. London is a key transit hub for global air networks, and the number of passengers continues to grow. Heathrow is the world's busiest airport in terms of international passenger traffic.
