U.S international travelers are always at the risk of being infected and becoming ill. Most travelers don't see the need of getting vaccinated before traveling outside the United States. Those who intend to travel to other countries are advised to be vaccinated for yellow fever, measles, mumps and rubella. Most of these diseases are not present in the United States but are plentiful in tropical countries.
