Requirements for vaccinations differ by country. Although there may not be any restrictions on direct travel to and from the United States, there may be restrictions if you travel indirectly and stop over in another country before reaching your final destination. Although not required, vaccinations against typhus, typhoid, and other diseases are advisable. The Centers for Disease Control and Prevention (CDC) maintains a web page to advise travelers of current conditions by country and region at http://cdc.gov/travel.
