Prevention of Typhoid Fever
People who travel to areas where typhoid fever is common should avoid eating raw vegetables and other foods served or stored at room temperature. Generally, people can safely consume the following: Foods that are served very hot immediately after cooking Bottled or canned beverages that are sealed Hot tea or coffee Fruit that they have peeled themselves People should assume that ice and water (unless it is boiled or chlorinated before use) are unsafe. Sealed bottled water should be used for brushing teeth. A vaccine given by mouth (orally) and a polysaccharide vaccine given by injection into a muscle can help prevent typhoid fever. Both vaccines are about 70% effective and have few side effects. Vaccination is recommended for Travelers to regions where typhoid fever is common People who live in a household with or who have close contact with carriers Laboratory workers who work with the bacteria People who remain at risk should receive a booster vaccine 2 years after receiving the injected vaccine and 5 years after receiving the oral vaccine. In the United States, most cases of typhoid fever occur in travelers returning from parts of the world where typhoid fever is common. Most of these cases could have been prevented if people had been vaccinated.
