Visas:
U.S. citizen tourists staying for fewer than 30 days do not require a visa, but
must possess a passport and may be asked to show an onward/return ticket.
Health risks: Thai authorities have confirmed human cases of the H5N1
strain of avian influenza, commonly known as the "bird flu." Travelers to
Thailand and other countries affected by the virus are cautioned to avoid
poultry farms, contact with animals in live food markets, and any surfaces that
appear to be contaminated with feces from poultry.
