What documents do I need to travel outside the United States? In general, you will need to present a passport from your country of citizenship or your refugee travel document to travel to a foreign country. In addition, the foreign country may have additional entry/exit requirements (such as a visa).
However, avian influenza A viruses are very contagious among birds and some of these viruses can sicken and even kill certain domesticated bird species including chickens, ducks, and turkeys. Infected birds can shed avian influenza A viruses in their saliva, nasal secretions, and feces.
Avian flu cannot yet be categorized as a pandemic, because the virus cannot yet cause sustained and efficient human-to-human transmission. Cases so far are recognized to have been transmitted from bird to human, but as of December 2006, there have been very few (if any) cases of proven human-to-human transmission.
