What is Typhoid Fever

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. Salmonella Typhi lives only in humans. Persons with Typhoid Fever carry the bacteria in their bloodstream and intestinal tract. In addition, a small number of persons, called carriers, recover from typhoid fever but continue to carry the bacteria. Both ill persons and carriers shed Salmonella Typhi in their feces (stool). About 5 percent of people infected with S. Typhi become lifelong carriers, releasing the germ in their stool for years, which can spread the disease.

Transmission of Typhoid Fever

Typhoid Fever

Persons with Typhoid Fever carry the bacteria in their bloodstream and intestinal tract. In addition, a small number of persons, called carriers, recover from typhoid fever but continue to carry the bacteria. Both ill persons and carriers shed Salmonella Typhi in their feces (stool). You can get Typhoid Fever if you eat food or drink beverages that have been handled by a person who is shedding Salmonella Typhi or if sewage contaminated with Salmonella Typhi bacteria gets into the water you use for drinking or washing food. Therefore, Typhoid Fever is more common in areas of the world where hand washing is less frequent and water is likely to be contaminated with sewage. Once Salmonella Typhi Bacteria are eaten or drunk, they multiply and spread into the bloodstream. The body reacts with fever and other signs and symptoms.

Precautions to avoid Typhoid Fever

Two basic actions can protect you from typhoid fever, avoid risky foods/ drinks and get vaccinated against typhoid fever.

  • If you drink water, buy it bottled or bring it to a rolling boil for 1 minute before you drink it. Bottled carbonated water is safer than un-carbonated water.
  • Ask for drinks without ice unless the ice is made from bottled or boiled water. Avoid popsicles and flavored ices that may have been made with contaminated water.
  • Eat foods that have been thoroughly cooked and that are still hot and steaming.
  • Avoid raw vegetables and fruits that cannot be peeled. Vegetables like lettuce are easily contaminated and are very hard to wash well.
  • When you eat raw fruit or vegetables that can be peeled, peel them yourself.
  • Avoid foods and beverages from street vendors. It is difficult for food to be kept clean on the street.
