Clean water supplies and effective waste disposal systems are the best
ways of preventing typhoid, but these are lacking in many countries. A
vaccine is available in the early 2000s that is about 70-percent effective
for several years.
Travelers to countries where typhoid fever is common should drink
only boiled or bottled water. They should eat only food that has been
properly cooked or fruit that they peel themselves and that has not
been washed with tap water. The Centers for Disease Control and
Prevention sums up advice for travelers this way: “Boil it, cook it, peel
it, or forget it.”
