Answer:
Typhoid fever is caused by Salmonella typhi bacteria. Typhoid fever is rare in developed countries. It is still a serious health threat in the developing world, especially for children.
Contaminated food and water or close contact with an infected person cause typhoid fever.
Prevention
Safe drinking water, improved sanitation and adequate medical care can help prevent and control typhoid fever. Unfortunately, in many developing nations, these may be difficult to achieve. For this reason, some experts believe that vaccines are the best way to control typhoid fever.
A vaccine is recommended if you live in or are traveling to areas where the risk of getting typhoid fever is high.
