Typhoid fever is a life-threatening illness caused by the Bacterium Salmonella Typhi. Typhoid fever is still common in the developing world, where it affects about 21.5 million persons each year. Typhoid fever can be prevented and can usually be treated with antibiotics.

How can you avoid typhoid fever?
Two basic actions can protect you from typhoid fever:
1.    Avoid risky foods and drinks.
2.    Get vaccinated against typhoid fever.
Vaccines
Two vaccines are available.
•    One is injected in a single dose about two weeks before exposure.
•    One is given orally in four capsules, with one capsule to be taken every other day.
Neither vaccine is 100 percent effective, and both require repeat immunizations as vaccine effectiveness diminishes over time.
Because the vaccine will not provide complete protection, follow these guidelines when traveling to high-risk areas as well:
•    Wash your hands. Frequent hand-washing is the best way to control infection. Wash your hands thoroughly with hot, soapy water, especially before eating or preparing food and after using the toilet. Carry an alcohol-based hand sanitizer for times when water is not available.
•    Avoid drinking untreated water. Contaminated drinking water is a particular problem in areas where typhoid is endemic. For that reason, drink only bottled water or canned or bottled carbonated beverages, wine and beer. Carbonated bottled water is safer than uncarbonated bottled water. Wipe the outside of all bottles and cans before you open them. Ask for drinks without ice. Use bottled water to brush your teeth, and try not to swallow water in the shower.
